JP5562731B2 - Method and system for converting CAD data for wooden house - Google Patents

Description

  The present invention can convert between any design CAD, structural CAD, and structural calculation CAD for a wooden house, and can convert CAD data for a wooden house that can be easily reconverted after data correction. The present invention relates to a method and a system thereof.

  At present, the design of wooden houses built by construction companies is mostly created by design CAD, the design of precut materials for wooden houses manufactured by the precut factory is created by structural CAD, and the strength calculation of wooden houses is It is done by structural calculation CAD. However, these CADs are developed in different data formats and are not compatible at all. For this reason, for example, when design CAD data is used for structural CAD, data is currently input using a keyboard. In particular, in the case of the conventional construction method, the number of types of precut materials to be used is extremely large, so that data input is complicated and there is a high risk of erroneous input.

  In order to link design CAD data, structural CAD data, and structural calculation CAD data, the Wooden House CAD / CAM Data Standardization Committee has been organized and CEDXM is the standard specification for wooden house CAD / CAM data.(Registered trademark)Was proposed. CEDXM(Registered trademark)Is described in XML (Extensible Markup Language) and is tagged so that it is easy to understand the contents. And CEDXM (Registered trademark)Can be expressed as part manufacturers and model numbers, so it can be used not only as a link between design CAD and precut CAD, but also as a standard data specification among housing production personnel.

If the precut factory can generate CAM data from the CAD data sent to the precut factory in the CEDXM (registered trademark) format by the construction company, it is expected that the precut work can be streamlined and streamlined. Furthermore, if the CAD / CAM data of the precut factory can be converted back to the design CAD of the construction company, it can be used as construction management data. However, in most cases, design CAD data from a construction company cannot be used as it is, even if it is put into the CAD / CAM of a precut factory in the CEDXM (registered trademark) format. This is because the design CAD data created by the construction company looks like a firm sketch, but in reality the walls overlap, the columns overlap, and the beams partially overlap. Because there are many things to do. Therefore, when generating structural CAD data for pre-cutting plants from the design CAD data of the construction company, data necessary for pre-cut materials (for example, how to handle end parts of horizontal members such as beams) is calculated, and structural safety Need to check above.

  However, many design CADs, structural CADs, and structural CADs are currently sold separately, and there is no compatibility between them. Therefore, when converting CAD data, conversion software between individual CADs must be created. However, most of the construction and pre-cut factories are small, and it is virtually impossible to hold a large number of conversion software. For this reason, no electronic data is exchanged between the design CAD and the structural CAD, or between the structural CAD and the structural calculation CAD, and the current situation is that the data is manually input via a keyboard. This inconvenience increases the design cost and places an excessive burden on the user.

  In addition, for example, when data is converted between a design CAD and a structural CAD, the design CAD does not have all the data necessary for the structural CAD, and all the data in one CAD is necessary for the other CAD. Not a translation. For example, as shown in FIG. 18, the design CAD has data items that are not normally required for the structural CAD, and at the same time, does not have some of the data items required for the structural CAD. That is, there are data items common to both CAD, unnecessary data items, and missing data items. Therefore, when design CAD data is converted to structural CAD data using a conventional conversion system, data for missing data items can be generated manually, etc., but unnecessary data items disappear and are included in the converted structural CAD. It will not be. As a result, conversion from design CAD to structural CAD is one-way, and when converting in the reverse direction (re-conversion), data items lost as unnecessary data items become insufficient data items, and data is generated again by manual input, etc. There is a need to. In actual wooden house design, it is often necessary to go back and forth between design CAD, structural CAD, and structural calculation CAD and repeat corrections. Therefore, if unnecessary data items are ignored, re-conversion takes time.

  Therefore, the object of the present invention is to enable conversion between arbitrary design CAD, structural CAD and structural calculation CAD for wooden houses, and also CAD for wooden houses that can be easily reconverted after data correction. A data conversion method and system are provided.

  As a result of earnest research in view of the above object, the present inventor, when converting between any design CAD for wooden houses, structural CAD and structural calculation CAD, (1) there is missing data and unnecessary data together with common data (2) Unnecessary data is ignored in the conventional conversion method. (3) Therefore, when reconverting in the opposite direction, the ignored unnecessary data becomes insufficient data and needs to be input and recalculated. In addition to providing a process for identifying unnecessary data, and saving the identified unnecessary data together with the conversion data and generated data, it can be used as it is when reconverting in the reverse direction, and is therefore ignored. It was discovered that the need for data input and recalculation was eliminated, and the present invention was conceived.

That is, the method of the present invention for converting wooden house design data created by the first CAD into data for the second CAD is as follows. (1) The first CAD data is converted to CEDXM (registered ) by the input means. entered in trademarks) format, (2) by comparing all the data items required for the second CAD and all data items of the first CAD by a specific means, (a) the second The first CAD data item corresponding to the CAD data item (hereinafter referred to as the corresponding data item), and (b) the first CAD data item that is insufficient to be converted to the second CAD ( (Hereinafter referred to as the missing data item) and (c) the first CAD data item that does not correspond to the second CAD data item (hereinafter referred to as the unnecessary data item), and (3) the conversion means According to the rules of the data item of the second CAD, the data of the corresponding data item Calculated and converted into data of the second CAD, (4) calculated in accordance with a stored algorithm the data of the missing item and generates data for the second CAD by generation means, (5) storage means stored in the second storage folder the unnecessary data item with converted data and the generated data for CAD, outputting the data in the storage folder to the second CAD by output means (6) Features.

It is preferable that the corresponding data items are sequentially deleted from the list of data items of the first CAD by unnecessary data item specifying means , and the last remaining data item is specified as the unnecessary data item.

  FirstBy calculation file creation meansCreate a calculation file containing all data items of the first CAD,By unnecessary data item identification meansThe corresponding data items are sequentially deleted from the data item list in the calculation file, and the last remaining data item is replaced with the unnecessary data item. Identify asIs preferred.

If the re-converted data of the first CAD in the second CAD, a calculation file containing the missing data item with all data items of the first CAD created by calculation file creation hand stage It is preferable that all data items necessary for the second CAD are compared with the data items of the calculation file by the comparison means .

It is preferable that arbitrary data among the data of the missing data items is manually input by an input unit, and data that can be calculated is generated by a generation unit according to the built-in algorithm.

The system of the present invention for converting wooden house design data created by the first CAD into data for the second CAD is as follows: (1) The first CAD data is in the CEDXM (registered trademark) format. And (2) by comparing all the data items necessary for the second CAD with all the data items of the first CAD, and (a) corresponding to the data items of the second CAD The first CAD data items (hereinafter referred to as corresponding data items), and (b) the first CAD data items that are insufficient to be converted into the second CAD (hereinafter referred to as insufficient data items). And (c) means for identifying the first CAD data item that does not correspond to the second CAD data item (hereinafter referred to as an unnecessary data item), and (3) the data of the corresponding data item Calculated according to the rules of the second CAD data item and converted to the second CAD data Means for converting, (4) means for incorporating a calculation algorithm for generating data of the second CAD corresponding to the data of the deficient items, and (5) data converted for the second CAD and A storage folder for storing the unnecessary data items together with the generated data, and (6) means for outputting the data in the storage folder to the second CAD.

Conversion system of the present invention, the first sequence to delete the corresponding data item from a list of data items CAD, preferably have a means of identifying the last remaining data items as the unnecessary data fields. Further, the conversion system of the present invention comprises means for creating a calculation file including all data items of the first CAD, and sequentially deletes the corresponding data items from the data item list in the calculation file. It is preferable to have means for making the remaining data items unnecessary data items.

  In the conversion system of the present invention, the calculation file includes the missing data items together with all the data items of the first CAD, and when the data of the first CAD is converted again to the second CAD, It is preferable to compare all data items required for the second CAD with the data items of the calculation file.

  The conversion system of the present invention preferably includes means for manually inputting arbitrary data among the data of the insufficient data items.

Since the present invention uses the CEDXM (registered trademark) format common to all CADs for designing wooden houses, any CAD conversion can be performed. In addition, the missing data items and unnecessary data items that inevitably exist between the pre-conversion CAD and post-conversion CAD are identified, and the data for the missing data items is newly generated according to the built-in algorithm, so the conversion work can be automated. In addition, since unnecessary data items are stored without being lost, unnecessary data items do not become insufficient data items when reconverting in the reverse direction.

  Therefore, for example, design CAD data is converted to structural CAD data, the design of the structural material is corrected, and the structural calculation CAD is used to confirm that the strength of the wooden house is sufficient. Even when re-converting to design CAD data for reflection in CAD, unnecessary data is saved, so it can be easily converted to design CAD without causing data shortage. As described above, the conversion system according to the present invention can reliably perform data conversion between any design CAD, structural CAD, and structural calculation CAD for a wooden house without causing a data shortage problem. As a result, it is possible to smoothly convert data between existing wooden house preparation CAD, structural CAD, and structural calculation CAD that exist without relation.

It is a fragmentary figure which shows the example of an ant mouthpiece.

As shown in FIG. 1, the conversion system of the present invention includes any design CAD-A, CAD-B, CAD-C... And any structure CAD-A, CAD-B. Arbitrary structural CAD-A, CAD-B ... and Arbitrary structural calculation CAD-A ..., Arbitrary structural CAD-A, CAD-B ... and arbitrary structural CAD- Data can be freely converted between A, CAD-B, etc. Since each CAD is composed of different format formats, CEDXM (registered trademark) is used as a common format format. In CEDXM (registered trademark) , each data is expressed in a tagged format.

  If the first CAD is called pre-conversion CAD and the second CAD is called post-conversion CAD, the CAD house file for wooden house design (before conversion) only contains a large amount of data. For example, as shown in simplified form in Table 1, data items B (1), B (3), B (5), B (6), B (8) corresponding to the data items necessary for the converted CAD And B (9), data items B (2), B (4), B (7) and B (10) unnecessary for the converted CAD, and missing data items. In the present invention, the corresponding data items B (1), B (3), B (5), B (6), B (8) and B (9) are calculated according to the CAD rules after conversion, and converted data is created. To do. For the missing data item, there is no data to be converted. Therefore, after inputting different data depending on the preference of the construction owner using the keyboard as necessary, calculation is performed according to a built-in algorithm, and data for converted CAD is generated. Unnecessary data items B (2), B (4), B (7), and B (10) are not included in the converted CAD by simple conversion processing, but are stored in the storage folder in the present invention, so they are converted. There is no missing data item when converting to the previous CAD in the reverse direction.

FIG. 2 is a flowchart showing the principle of the conversion system of the present invention. First, file B data of the first CAD (CAD before conversion ) is input in the CEDXM (registered trademark) format (steps 1 and 2). The number of data items in file B is m, and the type is B (m). Because it has a conversion to any wooden houses for CAD is CEDXM (registered trademark), it is possible to output the data in CEDXM (registered trademark) format, CEDXM (registered trademark) data entered by the format of self-format Can also be converted. Therefore, all the CAD data can be exchanged in the CEDXM (registered trademark) format.

  Next, the second CAD (converted CAD) is selected (step 2). The number of CAD data items after conversion is n, and the type is A (n).

  In order to identify unnecessary data items, a calculation file B1 including all data items B (m) of the file B is created (step 3). The number of data items in the calculation file B1 is m1, and the type is B1 (m1). Here, m1 = m and B1 (m1) = B (m).

  After conversion, each data item A (1), A (2), A (3) ... A (n) is converted into all data items B1 (1), B1 (2), B1 (3 ) ... Sequential comparison with B1 (m1) (step 4). FIG. 3 shows an example of a specific procedure of step 4. If any data item in CAD after conversion is A (c) and any data item in calculation file B1 is B1 (d), A (1) is B1 (1), B1 (2), B1 ( 3) ・ ・ ・ Compare sequentially with B1 (m1). In the example shown in Table 1, A (1) corresponds to B1 (1) (corresponding to B (1)), so the data of B1 (1) is calculated according to the rules of A (1) and converted data B1 ′ ( 1), which is converted to CAD A (1) data. While performing this conversion, B1 (1) is deleted from the data item list of the calculation file B1, and the number of data items is set to m1-1. This procedure is sequentially performed for c = 1, 2, 3,. As a result, B1 (3), B1 (5)... B1 (9) are also converted and deleted from the data item list of the calculation file B1.

  When c = n, check whether the number of data items m1 is greater than zero. When m1> 0, some data items of the calculation file B1 remain without being converted. That is, there are data items in the calculation file B1 that are not in the CAD after conversion. Since these data items do not need to be converted, they can be called unnecessary data items. The value of m1 at the time when step 5 is completed indicates the number of unnecessary data items. Unnecessary data items are stored in the storage folder F because they are necessary for reverse conversion, that is, conversion from A (n) to B (m) (step 5). When m1 = 0, all data items in the calculation file B1 have been converted, so there are no unnecessary data items in the calculation file B1.

  For example, as in A (11) shown in Table 1, if there is no data item corresponding to an arbitrary data item A (c) of the converted CAD in the calculation file B1, that is, if there is insufficient data in the CAD before conversion, It is determined whether or not the deficient data is arbitrary data that can vary depending on the preference of the construction owner. If the deficient data is arbitrary data, the data to compensate for the deficiency is input with the keyboard. In addition, if the deficient data has a property obtained by calculation, A (c) data is newly generated according to the built-in algorithm.

  The built-in algorithm is determined according to the type of structural material, the mode of joining, and the like. For example, if there are two structural materials that are to be joined at right angles, the design CAD does not specify the joining mode, so the necessary size data is created using this as the dovetail. Although details will be described later, the specific shape and size of the dovetail differs depending on each structural CAD (related to the tool size of a specific processing device), so conversion from design CAD to structural CAD Rather than deciding the shape and size of the ant mouth, determine only the length of the ant mouth (for example, D shown in (B) of FIG. 10), and then the specific shape and It is more efficient to determine the size. This is because the specific shape and size of the dovetail is necessary when processing individual precut materials from the structural CAD, but not when calculating the structure.

The converted CAD data consists of converted data, generated data, and unnecessary data. These data are stored in the residence folder F and output in the CEDXM (registered trademark) format.

  The flowchart of FIG. 2 shows the case of first conversion from the first CAD to the second CAD. However, the conversion system of the present invention performs the second CAD → after the first CAD → second CAD conversion. Conversion (reconversion) in the reverse direction of the first CAD can be easily performed, and reconversion from the first CAD to the second CAD can be easily performed. FIG. 4 is a flowchart including reconversion. In the case of re-conversion, since the house-specific storage folder F already exists, the missing data item F (p) is acquired from the house-specific storage folder F together with all the data items B (m) of the file B, and the calculation file B1 is created. . After that, conversion data and generated data are created in the same manner as in the flowchart of FIG. 2, and unnecessary data is specified.

  The present invention will be described in more detail with reference to the following specific examples, but the present invention is not limited thereto. Since there is an extremely large amount of structural material information, the following specific example shows an example of a calculation that is actually performed, but other calculations are also performed in the same manner.

Specific 1
For example, the case where the data of the file B of the design CAD-B in FIG. 1 is converted into the data of the structure CAD-A will be specifically described below with reference to FIG.

  The design data of the mansion that the file B of the selected design CAD-B has, for example, as shown in FIG. 8, simply indicates the state in which the structural materials are connected, and specifies the shape of the connecting part (joint, joint, etc.) Absent. The structural CAD data corresponding to the design CAD data is shown in FIG. However, the thickness of the structural material does not match between FIG. 8 and FIG. 9 for the purpose of illustration, and FIG. 9 shows the structural material in a separated state.

Among the data of design CAD-B file B, there is data relating to all structural materials, for example, there are many data relating to columns. The data of one pillar is shown as follows, for example.
Pillar 1
Start point End point X 100 100
Y 100 100
Z 540 3285
Width 105 × 105

In this way, design CAD data having a large number of structural material information is converted into the CEDXM (registered trademark) format. Expressed in CEDXM (registered trademark) format as an example one pillar members and one horizontal member of the structural material, it becomes as follows.

  For example, when the second structural material 2 is joined to the side surface of the first structural material 1 at a right angle, the design CAD data is such that one end of the second structural material 2 is the first as shown in FIG. The structure CAD data shows that the ant 2b provided at one end of the second structural material 2 is the first structural material as shown in (C) of FIG. The state of being housed in 1 ant hole is shown. However, since the shape and size of the ant 2b differ depending on the structural CAD, the structural CAD data converted from the design CAD data has the first end 2a of the second structural member 2 as shown in FIG. The shape and size of the ant 2b shown in FIG. 10C are set by the individual structural CAD. Therefore, the structural CAD data converted from the design CAD data by the conversion system of the present invention is the first structural material 1 until the end 2a of the second structural material 2 reaches the depth D as shown in FIG. It is assumed that it is housed in the hole.

  In the case of the first conversion, since there is no residence folder F, the data items of the calculation file B1 are exactly the same as the data items of the file B of the design CAD-B. That is, m1 = m and B1 (m1) = B (m). In the second and subsequent conversions, the conversion system of the present invention stores already-converted data, etc., in the residence storage folder F, so that calculation can be omitted if they are used as data items in the calculation file B1. . In this case, m1 = m + p and B1 (m1) = B (m) + F (p). However, F (p) is a missing data item.

  As a result of comparison between the data item of the structural CAD-A and the data item of the calculation file B1, the correspondence data is recognized, for example, the design data shown in (A) of FIG. 10 and the structural data shown in (C). . Therefore, the X coordinate of one end of the second structural material 2 is moved by D (the second structural material 2 is lengthened by D). Such conversion is performed on all the structural materials to be joined, and converted into the structure data shown in FIG. As already mentioned, the conversion from (B) to (C) is done by structural CAD itself.

For example, as shown in Fig. 11 (A), design CAD usually does not display braces that are not related to the design, so the calculation file B1 containing the data of file B of the design CAD-B lacks bracing data. Yes. Therefore, it is necessary to add bracing data (width, length, and position) to the structural CAD as shown in FIG. 11B and FIG. In FIG. 12, the braces 13 are provided on two diagonal lines of a quadrangle surrounded by pillar members 11, 11 ′ and horizontal members 12, 12 ′. Bracing data is generated according to a built-in algorithm for bracing in structural CAD. According to this built-in algorithm, the position where the bracing is provided is determined according to the following priority order.
(1) Avoid openings.
(2) Provide a brace preferentially at the corner of the outer wall.
(3) Provide bracing between columns exceeding one module.
(4) Determine the shape and size of each brace under these conditions.

  Since the built-in algorithms differ for each structural material, the conversion system of the present invention needs to incorporate algorithms for all types of structural materials. Built-in algorithms basically follow building standards.

  Data unnecessary for the structure CAD-A is stored in the residence storage folder F together with all converted data and all data generated by the built-in algorithm.

Concrete 2
When converting structural CAD-A data to structural calculation CAD-A data, as shown in FIG. 6, first, the data of structural CAD-A file A is input in the CEDXM (registered trademark) format (step 1). ). The number of data items in file A is n, and the type is A (n). Next, the structural calculation CAD-A is selected (step 2). The number of data items in the structural calculation CAD-A is x, and the type is C (x).

  In order to identify unnecessary data items, a calculation file A1 including all data items A (n) of file A is created (step 4). The number of data items in the calculation file A1 is n1, and the type is A1 (n1). For the first conversion, n1 = n and A1 (n1) = A (n). For the second and subsequent conversions, n1 = n + q and A1 (n1) = A (n) + F (q). . However, F (q) is a missing data item.

  Data items C (1), C (2), C (3) ... C (x) of structural calculation CAD-A are all data items A1 (1), A1 (2), A1 of calculation file A1 (3)... A1 (n1) is sequentially compared (step 5). FIG. 7 shows an example of a specific procedure of step 5. As a comparison between the data item of structural calculation CAD-A and the data item of calculation file A1, for example, in the case of a load-bearing wall, whether structural material data is in calculation file A1, whether floor height data is a calculation file It is checked whether it is in A1, whether the type of bearing wall, use location, and usage method are in calculation file A1, and if not, data is input using a keyboard. The above is an example of check items, and all other necessary items are checked. Further, for example, when there are joints and joints, as shown in FIGS. 13A and 13B, the structure is converted to a structure without joints and joints. In this way, the structural calculation ignores the joining mode of the structural materials and treats them as an integral structure.

  Since a house is generally horizontally long, the area when viewed from the L direction in FIG. 14A is larger than the area when viewed from the D direction. Therefore, as shown in FIG. 14B, the area (indicated by the hatched portion 10a) when viewed from the L direction is referred to as a found area. Since the wind in the L direction gives the house more power than the wind in the D direction, the area found is important when assessing the wind resistance of the house. However, since the calculation file A1 has no data for the found area, it must be calculated according to the built-in algorithm. That is, the found area is insufficient data, and the calculated found area is generated data. For example, if the proof strength for the found area is insufficient according to the Building Standards Law, change some of the structural CAD data for calculating the found area, convert it again to the structural calculation CAD, recalculate the proof strength for the found area, and evaluate To do.

  As shown in FIG. 15, the structural CAD has data on the fire-cracking base 3 provided on the horizontal members 1 and 2. Since a reinforcing material such as plywood is attached on the fire-cracking base 3, the load resistance is evaluated. When doing so, the data of the struck base 3 is not necessary. Therefore, in the case of conversion from structural CAD to structural calculation CAD, the data of the flame laying base 3 is handled as unnecessary data.

  Although the deficient data and unnecessary data have been exemplified above, there are of course many other deficient data and unnecessary data, and these are processed in the same manner as described above.

Example 3
It may be necessary to convert between structural CADs. This is because each structural CAD corresponds to an NC machine, so if the NC machine used for precutting is changed, the structural CAD must also be changed. For example, since the dimensions of each part of the structural material depend on the attributes of the NC processing machine, the dimensions of each part of the structural material must be changed according to the change of the NC processing machine (change of the structural CAD). In the example shown in FIG. 16, (A) shows a sickle of structure CAD-A, and (B) shows a sickle of structure CAD-B. Because sickle size and shape are different, when converting the sickle data structures CAD-A sickle data structures CAD-B, the distance between the bonding lines and the grid lines of the structural member 1 and 2 to D _B from D _A change. Thus, by converting according to the rules of each structural CAD, the data of the first structural CAD can be converted into the data of the second structural CAD. Similarly, different because each shape of the Joint also structured CAD as shown in Figure 17, the distance D _A it is necessary to perform a conversion to change D _B.
