Specifically, the computer equipment obtains model surface information of each model surface of the wall keel model to be connected and obtains a bottom guide beam model to be connected. The model surface information may include, but is not limited to, the shape, size, position, orientation of the model surface, and the belonging solid model. And the computer equipment processes every two of the model surfaces of the wall keel models to be connected and the bottom guide beam models to be connected by adopting the adjacent algorithm, so that adjacent information representing the adjacent state between each model surface of the wall keel models to be connected and the bottom guide beam models to be connected is obtained. Alternatively, the adjacent state may include adjacent and non-adjacent. The adjacent information can represent the adjacent state of each model surface of the wall keel model to be connected and each bottom guide beam model to be connected.

And S13, determining a placing surface, a placing point and a placing direction of a connecting node required by the connection between the wall keel model to be connected and the bottom guide beam model to be connected according to the adjacent information.

The computer equipment can determine a required connecting node between the wall keel model to be connected and the bottom guide beam model to be connected according to the adjacent information, and specifically, the computer equipment can determine the placement direction of the connecting node according to the model surface orientations of two entity models with adjacent relation in the adjacent information; the computer equipment can also determine the placement point of the connecting node according to the size and the position of the overlapped part of the model surfaces of the two solid models; or the computer equipment determines the placing surface of the connecting node according to the positions and the orientations of the model surfaces of the two solid models; optionally, the method may further include the step that the computer device determines the size of the connection node according to the thicknesses of the wall keel model to be connected and the bottom guide beam model to be connected, to which the two model surfaces with the adjacent relationship in the adjacent information respectively belong; optionally, the type and number of the connection nodes required between the wall keel model to be connected and the bottom guide beam model to be connected may also be determined by the computer device according to the adjacent information, which is not limited in this embodiment.

And S14, generating the connecting node according to the placing surface, the placing point and the placing direction.

Specifically, the computer-based equipment can automatically generate the connecting node capable of connecting the wall keel model to be connected and the bottom guide beam model to be connected according to the placing surface, the placing point and the placing direction of the connecting node. Specifically, the computer device may use the placement point as the origin of coordinates of its own coordinate system of the connected node, use the placement surface as a generation surface of the connected node, and automatically generate the connected node according to the placement direction, thereby completing the automatic placement of the connected node.

In this embodiment, the computer device obtains the wall keel model to be connected and the bottom guide beam model to be connected, and determines the adjacent information of the wall keel model to be connected and the bottom guide beam model to be connected by using a preset adjacent algorithm according to the model surface information of the wall keel model to be connected and the model surface information of the bottom guide beam model to be connected. Because the adjacent information is used for representing the adjacent state of each model surface between different entity models, and the adjacent algorithm is an algorithm for determining the adjacent relation between the model surfaces according to the intersection state after the model surfaces are extended, the computer equipment can automatically and accurately determine the wall keel model to be connected and the bottom guide beam model to be connected, on which the connecting nodes need to be placed.

The method can solve the problems of low efficiency and easy error caused by the traditional mode of manually placing the connecting nodes, thereby greatly shortening the generation time of the connecting nodes between the wall keel model to be connected and the bottom guide beam model to be connected and greatly improving the design efficiency of the connecting nodes; meanwhile, the accuracy rate of placing the connection nodes is greatly improved. In this embodiment, through the automatic generation connected node for model design's degree of automation is higher, consequently very big reduction model design's the degree of difficulty, makes the designer just can accomplish model design's relevant part design through simple study, therefore learning cost greatly reduced, thereby reduced design cost.

Optionally, on the basis of the foregoing embodiment, one possible implementation manner of the foregoing step S12 may include: performing adjacent information judgment operation on each model surface of each wall keel model to be connected and each bottom guide beam model to be connected pairwise to obtain adjacent information; the adjacent information comprises at least one group of model identification pairs with incidence relation and information of model surfaces with adjacent relation in the model identification pairs, and the model identification pairs comprise model identifications of a wall keel model to be connected and model identifications of a bottom guide beam model to be connected. Specifically, the computer equipment can combine each model surface of a wall keel model to be connected and one bottom guide beam model to be connected in pairs to form a combined pair of which the adjacent relation needs to be judged. For example, the wall keel model to be connected has six model surfaces a, B, c, d, e and f, and the bottom guide beam model B to be connected, and a combination pair formed after two-two combination comprises: aB. bB, cB, dB, eB and fB. Then, the computer device performs an adjacency information determination operation on the formed combination pairs using the adjacency algorithm, thereby obtaining an adjacency state of each combination pair. The model identification of the wall keel model to be connected and the model identification of the bottom guide beam model to be connected form a model identification pair, and the combination pair between the two and the adjacent state of the combination pair can be used as part or all of the adjacent information. And after the computer equipment executes the operation on each wall keel model to be connected and each bottom guide beam model to be connected, the adjacent information can be obtained. In this embodiment, the computer device can perform the adjacent information determination operation on each model surface of each wall keel model to be connected and each bottom guide beam model to be connected in pairs by using a preset adjacent algorithm, so as to obtain adjacent information, where the adjacent information includes at least one group of model identifier pairs having an association relationship and information of model surfaces having an adjacent relationship in the model identifier pairs, and the model identifier pairs include a model identifier of the wall keel model to be connected and a model identifier of the bottom guide beam model to be connected. Based on this, the computer equipment can be according to above-mentioned adjacent information, select the wall fossil fragments model of waiting to connect that needs connect and wait to connect the end nose girder model from a plurality of entity models of design model automatically to can be at the wall fossil fragments model of waiting to connect that the confirmed needs connect and wait to connect the model surface of end nose girder model and automatically generate connected node, and then improved connected node's the efficiency of placing and connected node's the rate of accuracy of placing, and then reduced design cost.

In one embodiment, the neighboring information determining operation may be as shown in fig. 3, and includes:

s121, generating a corresponding virtual entity along the normal direction of the surface of the first model; the size of a cross section, perpendicular to the normal direction of the first model surface, of the virtual entity is the same as that of the first model surface, and the thickness of the virtual entity is used for representing a judgment threshold value of the adjacent relation.

Specifically, when the computer device performs the adjacent information judgment operation between two solid models, the first model surface of the first solid model is determined first, where the first solid model may be any one of the two solid models, or may be determined according to a priority set in a rule, and usually, when the wall keel model and the bottom guide beam model perform the adjacent information judgment, the wall keel model may be performed as the first model where the first model surface is located. The computer device generates a virtual entity with a certain thickness in the normal direction of the first model surface, the virtual entity is attached to the first model surface, it should be noted that the size of the cross section of the virtual entity perpendicular to the normal direction of the first model surface is the same as the size of the first model surface, meanwhile, the thickness of the virtual entity is not limited, and generally, the virtual entity is preset for judgment as long as the adjacent relationship can be represented. For example, if the thickness exceeds X centimeters, it is determined that a connection node is not required to be arranged between the two solid models, the two solid models are non-adjacent solid models, and if the thickness is less than X centimeters, it is determined that the two solid models are required to be connected, and if the thickness is adjacent to the two solid models, the thickness of the virtual entity can be set to X centimeters. It will be readily appreciated that the virtual entity may be a solid portion extending the first model surface by a thickness in a normal direction.

S122, acquiring an intersection state between the virtual entity and the second model; wherein the second model is a different solid model than the first model.

Specifically, the computer device may perform intersection determination on the virtual entity and a second model different from the first model, so as to obtain an intersection state of the virtual entity and the second model, and may also perform intersection determination between the virtual entity and a second model surface on the second model; alternatively, the computer device may determine whether two objects intersect, that is, respectively project the two objects in three directions in the three-dimensional space, and then determine whether the projections of the two objects in each direction overlap, and if the projections in the three directions overlap, it may be determined that the two objects intersect, and if the projections in more than one direction do not overlap, it may be determined that the two objects do not intersect.

And S123A, if the intersection state is intersection, determining that the adjacent state of the first model surface and the second model is adjacent.

S123B, if the intersection states are not intersected, determining that the adjacent states of the first model surface and the second model are not adjacent.

Specifically, when the intersection state is intersection, it may be determined that the first model surface and the second model are adjacent; when the intersection states are not intersected, the first model surface and the second model can be determined to be non-adjacent states. Optionally, when all the model surfaces of the first model are not adjacent to the second model, it may be determined that the first model and the second model are not adjacent; the first model and the second model may be determined to be adjacent if one of the surfaces of the first model is adjacent to the second model.

In the neighboring information determining operation related in this embodiment, the computer device generates a corresponding virtual entity by a normal direction along the first model surface, and obtains an intersection state between the virtual entity and a second model different from the first model, when the intersection state is intersection, it is determined that the neighboring states of the first model surface and the second model are neighboring, and if the intersection state is non-intersection, it is determined that the neighboring states of the first model surface and the second model are not neighboring. The size of the cross section of the virtual entity perpendicular to the normal direction of the first model surface is the same as that of the first model surface, and the thickness of the virtual entity is used for representing the judgment threshold value of the adjacent relation, so that the computer equipment can realize accurate judgment of the adjacent relation through the intersection state of the virtual entity and the second model, and adjust the judgment threshold value of the adjacent relation through the thickness of the virtual entity.

Optionally, on the basis of the foregoing embodiment, a possible implementation manner of step S13 may be as shown in fig. 4, and includes:

s131, according to the adjacent information, determining an overlapping area between adjacent surfaces of the wall keel model to be connected and the bottom guide beam model to be connected, which are adjacent in each group of model identification pairs.

Specifically, each group of model identification pairs includes a wall keel model to be connected and a bottom guide beam model to be connected, which have an association relationship, where the association relationship may be two entity models for determining an adjacent relationship. The computer device may calculate an overlapping area of the adjacent model surfaces between the two adjacent solid models according to the adjacent information between the two solid models, for example, project the model surfaces of the wall keel model to be connected and the bottom guide beam model to be connected to the target direction, and calculate an area of an overlapping portion of the two in the projected area as an area of the overlapping area. The target direction is a direction in which a projected area is the largest in a three-dimensional space in which the solid model is located.

S132, acquiring the central point of each overlapping area.

Specifically, the computer device may obtain a center point of the overlap region by using a preset algorithm, where a projection of the center point in the target direction is a point of the center of the projection region of the adjacent model surface in the target direction.

And S133, taking a surface which is closest to the central point in the model surface of the bottom guide beam model to be connected as the placing surface.

And S134, taking the projection of the central point on the placing surface as the placing point.

And S135, taking the web orientation of the wall keel model to be connected as the placing direction.

Specifically, the computer device may calculate a distance between each model surface of the to-be-connected bottom guide beam model and a central point, then use a model surface closest to the central point as a placement surface of the connection node, project the central point on the placement surface, then use the projection point as a placement point of the connection node, and at the same time, the computer device uses a web orientation of the to-be-connected wall keel model as a placement direction of the connection node. The position and pose of one connecting node can be determined by the placement point, the placement surface and the placement direction. Alternatively, the above-mentioned connection node may be a screw, the result of which placement can be seen in fig. 4 a.

In this embodiment, computer equipment is according to adjacent information, determine the overlap region between the adjacent model surface of every group model identification centering adjacent waited to connect wall fossil fragments model and waited to connect the end guide girder model, then acquire the central point of every overlap region, and will wait to connect the face nearest with the distance of central point in the model surface of end guide girder model, as placing the face, regard the projection of central point on placing the face as placing the point at last, will wait to connect the web orientation of wall fossil fragments model as placing the direction, thereby realize carrying out accurate location with the generating position of connected node, and then make the automation of connected node place more accurately.

After the step S131, the method may further include: judging whether the area of the overlapping area is larger than a preset placing area threshold value or not; and if so, executing the step of acquiring the central point of each overlapping area. Specifically, the computer device determines whether the area of the overlap region is larger than a preset placement area threshold, and determines that the overlap region can place the connection node if the area of the impact region is larger than the preset placement area threshold, so that the step of obtaining the center point of each overlap region is performed to realize the automatic placement of the connection node; otherwise, the area of the overlapped area is considered to be too small, the connecting nodes cannot be placed normally, and the connecting nodes are not placed any more. Optionally, when the connection node is a screw, that is, the wall keel model to be connected and the bottom guide beam model to be connected are connected by using a screw, the placement area threshold may be set to 10 square millimeters.
