The Revit structural calculation model includes structural information.
Specifically, the structural information includes connection information of adjacent beams and columns, a distance between adjacent columns and adjacent beams, rigid connection information between adjacent beams, and hinge information between adjacent beams.
And step S03, aligning the beams and the columns of the Revit structure calculation model by using a preset Dynamo program, and correctly connecting adjacent beams to obtain the structure model construction drawing shown in FIG. 7. A structural plan construction drawing as shown in fig. 8 is formed based on the X-axis and Y-axis data of the structural model construction drawing.
Specifically, the alignment between the beams and the columns of the Revit structural calculation model using the preset Dynamo program specifically includes: the automatic connection between all beams and columns of the Revit structural calculation model was cancelled using a preset Dynamo program as shown in fig. 9, and then all beams of the Revit structural calculation model were aligned to the column side adjacent thereto.
Specifically, the step of correctly connecting adjacent beams of the Revit structural calculation model by using a preset Dynamo program specifically comprises the following steps of: the automatic connection between adjacent beams of the Revit structural calculation model was cancelled using a preset Dynamo program as shown in fig. 9. And combining and connecting all the beams which are in the same direction and are rigidly connected with each other in the Revit structure calculation model according to the rigid connection symbols by using a preset Dynamo program shown in figure 10.

This prevents the hinged ends from merging when merging all of the beams in the same direction but rigidly joined to each other.
All the beams which are in the same direction and are rigidly connected with each other are connected in a combining way, so that the connecting mode of the rigidly connected beams can be intuitively known. And carry out collision inspection with all roof beams, the roof beam that collides each other is carried out the roof beam limit and is aimed at, then lets articulated roof beam align rather than merge, can understand directly perceivedly which one end is the hinged end. Parameters of the beam family are automatically modified, so that the connection between the adjacent beams conforms to a building scheme, and the modification is quick, accurate and efficient.
And if the rigid connection information between the adjacent beams in the Revit structure calculation model is read by using a preset Dynamo program and the hinge joint information between the adjacent beams fails, returning to the step S02.
Specifically, the step of forming the structural plane construction drawing according to the X-axis and Y-axis data of the structural model construction drawing comprises the step of forming the structural plane construction drawing of the building layer through Revit software according to the X-axis and Y-axis data of a plurality of beams located on the same plane in the structural model construction drawing.
According to the invention, the beam family and the column family are established firstly, so that the later-stage data can be modified consistently, the consistency of modification of the construction drawing is ensured, the operation is reduced, and the efficiency is improved. The YJK-Revit plug-in is led into YJK structure software to carry out structure calculation and then is transmitted back, so that corresponding structure data can be obtained quickly, manual input is not needed, and the method is quick and convenient. The beams and the columns of the Revit structure calculation model are aligned by using a preset Dynamo program, and adjacent beams are correctly connected, so that the degree of automation is high, manual adjustment is not needed, beam and column mistaken deletion or adjustment mistake during manual adjustment is prevented, and the integrity and the accuracy are ensured.
