Arranging of arm starting point mainly is divided into following three kinds of situations:
(1) starting point is separated, i.e. this arm and other arm onrelevant are branches independently;
(2) starting point of this arm is the distal point of front arm, simultaneously with preceding arm latter end in the same way, the caliber difference, for example, suppose that arm 1 to 3 is connected in series successively, at this moment, the distal point of the starting point of arm 1 for being responsible for, the starting point of arm 2 is that the starting point of the distal point arm 3 of arm 1 is the distal point of arm 2; Wherein, when design, in order to make first section of this arm and preceding arm latter end in the same way, need the first segment length of given this arm, particularly, length can be by conveniently getting any unidirectional (XYZ) length or true length, differentiate then and select for use, concrete expression mode can be in the following ways: X300 represents to extend on the directions X point of 300 correspondences, and Y600 represents to extend on the Y-direction point of 600 correspondences, represents true length (tiltedly long) when the unmatched asyllabia of 800 expressions is female, like this, according to condition in the same way just can determine preceding 2 points (Point0 and 1) of this arm coordinate data (X, Y, Z);
(3) starting point of this arm is a middle part point, that is to say that starting point is the middle part point (bifurcation point) of other arm; At this moment, when design, need determine by-pass line K, the distance of segment number I and distance section initial point, the first section I section with arm K expressing this arm forms the fork section.
In addition, mainly there are following two kinds of situations in arm for first section: fork section or reducer.
When expression each pipeline section of pipeline and pipeline parts install and fix flange or live flange, can be by the mode shown in table 1 and the table 2:

Table 1
As shown in table 1, F represents mounting flange (FIXED FLANGE), and L represents the flange (LOOSE FLANGE) of living.
Table 2
As shown in table 2, for the reducing pipeline section of special shape, can represent its flange fixation case equally.
When detailing(of parts (floor plan), the user passes through the input caliber, external diameter of pipe, and flange diameter, flange thickness, bending radius etc. all adopt the parameter of current pipeline, the content of input can be marked in the arrangenent diagram that generates, thereby avoid hand drawn.In addition, in arrangenent diagram (detail drawing), comprise straight tube, elbow, be furnished with multiple pipeline parts such as the elbow of short tube, many siphunculus, reducer pipe, the parameter of all pipeline parts is used by analysis and is recorded in the database in the process that the pipeline model forms, draw according to this and come out to be detail drawing, that is to say that detail drawing is the expression to all pipe fittings.And, can comprise gather (for example, can be expressed as 2 at identical elbow, draw a detail drawing, elbow quantity record 2) to identical pipe fitting in the detail drawing
More because of parameter, external diameter of pipe and flange diameter and thickness are to be chosen automatically by program according to the type of caliber and pipe, if the type of pipe does not determine that then being defaulted as flanged (FLGD) pipeline section type is XX, not flanged is XS; If the type of flange does not determine that then being defaulted as flange type is Flange PN1.0.As shown in Figure 3, the parameter of fork pipeline section Line-Y detail drawing shown in Figure 3, MainLine Length represents the length be responsible for, SubLine Length represents the length of arm; Start Length is the distance apart from main leg's starting point, and Y-angle is the angle of bifurcated pipe.These parameters are to be analyzed automatically by program according to the data of the Trunk Line under the bifurcated pipe and by-pass line to determine, and draw out detail drawing according to this.
In addition, below each detail drawing, can mark the material list of each pipeline segmentation.
Can straight line be reference point, copy the relevant position of duplicating material table, in material list, mark the length of straight section, the angle of elbow and corresponding flange
Concrete pipeline parts can (for example be selected from the tens of kinds of pipeline section shapes that common graphics software provides, comprise straight tube, elbow, fork, parts such as reducing), automatically draw each section detail drawing of the pipeline that calculates based on the stereoscopic model of drawing (comprising the combination of selected pipeline parts), automatically distribute pipeline section, and be equipped with sequence number and mark, automatically three-dimensional conduit line map is converted into and dissects two dimension view--be used for the General Arrangement of utilities pipeline, or the interference checking of many pipelines article two,, can store the data of pipeline afterwards, in order to adjusting and checking, and with the automatic typing Excel of the material list of pipeline file, in order to gathering.
With the stereoscopic model of pipe system from least one direction projection on given plane, when obtaining the arrangenent diagram of pipe system, when whenever carrying out projection from a direction, all need model is copied, perhaps, can in advance stereoscopic model be copied according to the number of projecting direction; Whenever after a direction is carried out projection to the model of pipe system, the stereoscopic model of pipe system is rotated, and the model of mobile pipe system; With through rotation and mobile model projection on given plane, thereby avoid the projection of model on given plane to overlap each other.
(that is, drawing floor plan) is the projection line with two-dimentional lines direct representation object because 2D draws, and therefore, in the process that 2D draws, the X-Y scheme that need draw on the XY plane of the model space is then in paper space viewport layout.
Preferably, by means of computer equipment, at the drafting floor plan quantity of 3D model by required view is copied, be rotated by required respectively, move to suitable position, make the direct projection of direction (XY plane) of vertical view go out required each X-Y scheme (floor plan); Wherein, for vertical view, owing to be vertical view in the XY plane projection, therefore also can not change the position of master mould.
For front view (front view), need copy pipeline 3D model, will copy model and turn 90 degrees around the X-axis dextrorotation, make the copy model be projected as the front view of model at the XY face; And need make the copy model be positioned at the top of master mould on the XY plane with the copy model along Y direction displacement Ly, be the position of front view.Wherein, displacement Ly should be greater than 2 times of the total Y values of pipeline, make that front view can not overlap with vertical view among the 2D figure of projection;
For left view, then need to copy pipeline 3D model, will copy model and be rotated counterclockwise 90 degree around X-axis, be rotated counterclockwise 90 degree around Y-axis again, make the copy model be projected as the left view of model at the XY face; And will copy model and move Ly along Y direction, along directions X displacement Lx, make the copy model be positioned at the upper right quarter of master mould on the XY plane, be the position of front view, wherein, selecting the purpose of displacement Ly is for concordant with front view, and displacement Lx should be greater than 2 times of the total X values of pipeline, make that left view can not overlap with front view among the 2D figure of projection.
For the drafting of right view, then similar with the left view method, carry out symmetrical treatment and get final product.
So just can access the floor plan shown in Fig. 5 and Fig. 6, wherein, can pipeline structure be shown at 1 to 4 by left view and right view, and, the pipe system in the time of in front view and planimetric map, can illustrating with A, B and C axle as reference equally and the Different Plane of pipe system.And, no matter be front view, planimetric map, left view, right view and southwestern axonometric drawing, each other can't be overlapping, can not influence the staff and consult.
As shown in Figure 4, suppose to exist 1 person in charge and two arms (arm 1 and arm 2), can be from left to right, an ordering behind the former head, and, the line segment of every pipeline from top to bottom by rows, the pipe fitting detail drawing of each line segment is from left to right arranged, the sequence number of all detail drawings can be fully (A-＞Z) continuously.
Position relation by each detail drawing of illustrating for example with Fig. 4 with and represented content separately, make operating personnel be convenient to each pipe fitting detail drawing is checked.First section on the main line has two pipe fitting detail drawings: detail drawing A and B.
At paper space after once projection goes out the 2D figure of required each view on the XY plane, just can be in the explanation of the appropriate location of each view filling line of vision, the 2D figure of each view is copied back the XY plane of the model space, and like this, that present to the user is the 2D figure of the pipeline that has mark that goes out of projection.After above-mentioned processing, can obtain the piping diagram that an actual engineering is used, expressed the relation of pipeline and post layer equipment, and the detail drawing of each pipe fitting.Thereby can reduce the manually-operated amount in the floor plan drawing process, and can avoid a large amount of processing procedures such as pipeline parts mark to the influence of drawing accuracy.
It should be noted that, interface shown in Fig. 2 and only be concrete example for the expression of each parameter, and be not used in restriction the present invention, in actual applications, can make amendment and adjust above-mentioned interface, also can provide other interface to reach the purpose that is projected as floor plan after the three-dimensional pipeline model of design.
