Institute provides threedimensional model and corresponding flat facade two dimension drawing.The threedimensional model that designing institute provides only has profile, without corresponding data,
In special-shaped steel reinforced concrete structural elements, it is impossible to well guide field construction.We use the Revit software in BIM system, set up three
Dimension module obtains to cut out required cross section according to construction requirement after design confirms, arbitrarily extracts data, and guide field is constructed.
Build three-dimensional BIM model to comprise the following steps:
1, plane dropping place is imported in Revit software, locking；Again the rhinoceros form model that designing institute provides is imported
In Revit software, three-dimensional references point overlaps with plane dropping place datum mark, locking；By tripleplane by member planar subpoint
Position is distributed on figure, and CCP position is provided by designing institute, and auxiliary magnet position will be split voluntarily according to member profile feature, size
Add；
2, after plane each point position has been checked, give plane each point position according to elevation high-rise, with designing institute provide three
Dimension module is checked, and controls dropping place point position, and (auxiliary magnet position is complicated according to component to add auxiliary magnet position, control member position and moulding
Degree determines quantity, and at big radian curved surface, auxiliary magnet is close, and at little radian curved surface, auxiliary magnet is few, and the place of facing directly only needs head and the tail two
Point)；
3, generating line after each three-dimensional point position has been checked, line meets formation skeleton control, the head and the tail two of control wheel profile
The positions and dimensions of end section, generates threedimensional model in Revit software, and the threedimensional model that designing institute provides is checked；
4, Revit model send out in designing institute confirm, confirm errorless after, can in Revit model according to construction requirement cut
Going out required cross section, extract data, guide field is constructed.
But, above-mentioned detailed description of the invention is exemplary, is to preferably enable those skilled in the art
Understand this patent, it is impossible to be not understood as this patent is included the restriction of scope；As long as the institute according to spirit disclosed in this patent
Any equivalent change made or modification, each fall within the scope that this patent includes.
