Both prior art examples remain silent on automatic determination of wall connections. Both prior art examples remain silent on creation of 3D spaces directly. Once walls are drawn, a slab can be added.īoth prior art examples allow to model connected walls and a corresponding slab via a procedure involving a plurality of sequential steps. See, for example, OnapMenJE, entitled “AutoCAD Classes Fast 3D Wall” (2014). Walls associated with the outline can be added via the POLYSOLID command, by specifying a height and a thickness, and by further specifying (a part of) the outline as starting point.
AutoCAD 2013) a two-dimensional outline for multiple walls can be drawn via the PLINE command. See, for example,, entitled “BricsCAD BIM Basics-How to create walls” (2014). A corresponding slab can be inserted via boundary detection and the EXTRUDE command. Multiple walls can be connected via the BIMCONNECT command. V14) a wall can be created via the POLYSOLID command. BACKGROUNDĭrawing walls and slabs for a building in a computer-aided design (CAD) model, such as a building information model (BIM), typically requires many user operations. The invention pertains to the technical field of computer-aided design (CAD), and in particular building information modeling. 17, 2018, which is hereby incorporated by reference in its entirety as if fully set forth herein.
