The above examples are explained as follows: revit is the name of a suite of software series available from Autodesk. The Revit series software is constructed for a Building Information Model (BIM) and can help architects to design, build and maintain buildings with better quality and higher energy efficiency.
Because the common BIM (building Information modeling) modeling software cannot expand the curved surface of the spatial three-dimensional heterotype structure model into a single plane, the high-level Rhino modeling software proposed by Robert McNeel can well control the curve degree of the model surface. According to the design and manufacture of the chamfer template at the corner, the problem of unfolding of the spatial special-shaped structural curved surface is solved through Revit conventional modeling and Rhino modeling analysis, so that the structural division of the template is determined, the template manufacturing precision is finally improved, the curved path is reduced on a construction site, the rework time is reduced, and the construction quality and the construction efficiency are improved.
Illustratively, the specific process analysis for step two BIM modeling is as follows: the model established by Revit is exported to a DFX format and then imported to the Rhino, and from a perspective view, it is found that the surface mesh of the chamfer model is changed into a triangular mesh, because Revit adopts polygon modeling, and Rhino adopts NURBS modeling, which is unfavorable for curved surface expansion and analysis.
Respectively drawing a space three-dimensional curve and a chamfer section outline of 5 chamfers in the Rhino, generating a chamfer model through a curved surface lofting command Loft, picking up a chamfer curved surface, unfolding through a curved surface unfolding and flattening command UnrollSrf, wherein the plane is a curved surface connected with concrete in the template, and marking the corresponding size of the unfolded plane.
When the curved surface is unfolded into a plane, the surface area of the curved surface is unchanged, that is, the surface area of the curved surface is the same as that of the unfolded plane corresponding to the curved surface. Inquiring and comparing the surface Area before and after the expansion of each chamfer curved surface through an Area command Area in the Rhino, calculating the difference value of the surface areas,it can be seen that the absolute values of the differences are all less than or equal to 2mm2The error is within the modeling allowable error range in the Rhino software, no influence is caused on site construction, and the error can be ignored, so that the method proves that the error is avoided by using the method, and the method is shown in fig. 7, fig. 8 and table 1.

setting the maximum uniform load F as 32360N/m2The distance between the back ridges is 20cm, and the rotation angle is 4 degrees. In order to simplify the calculation, three components of the back ridge, the purline (namely the arc purline) and the panel (comprising the vertical panel and the haunched panel) are simplified into two components of the back ridge, the purline and the panel. Selecting a C3D8RH hexahedron as a grid unit for grid division; according to the integral stress analysis of the three-dimensional model, the maximum deformation position is in the middle of the panel, and the maximum displacement value is 7.11 multiplied by 10-6And m is selected. The maximum stress of the back edge is 1.08 multiplied by 10 according to the stress analysis of the back edge5Pa, less than the maximum allowable stress value of the specification, and the maximum stress position is the chamfer angle of the template. The maximum deformation value of the dorsal bar is 3.49 multiplied by 10-6And m is smaller than the maximum allowable deformation value of the specification, and the maximum deformation position is the chamfer of the template. The maximum stress of the purline and the panel is 6.45 multiplied by 10 which is known by the stress analysis of the purline and the panel5Pa, less than the standard allowable maximum stress value, and the position of the purline is at the chamfer; the maximum deformation value of the purline and the panel is 7.11 multiplied by 10-6m, less than the maximum deformation allowed by the specification, located in the middle of the panel. Through comparison, the stress of the back edge and the purline at the chamfer is maximum, and although the standard requirements are met, reinforcement treatment should be carried out again in actual construction.
