Working faster with 3D solids

Many modeling tools in the 3D Objects task area create general 3D objects, regardless of whether the source or result is delimited by curves. However, when it comes to complex, polygonal objects consisting of countless small surfaces that are planar, it does not make sense to create BREPS (surface models) or NURBS objects.

So that you can work faster with complex 3D objects, Allplan creates general 3D objects only when these objects are required. When the initial solids and paths consist of polyhedrons and polygons, the modeling tools create polygonal 3D solids, if this is possible, or Allplan automatically converts the results to polygonal 3D solids.

The following tools create polygonal 3D solids if this is possible:

• General polygonal 3D objects will be converted automatically to polygonal 3D solids; this also applies to user-defined architectural elements that were converted from these objects.
• Extrude
  (when extruding or cutting out general polygonal 3D objects)
• Boolean functions
  • Union
  • Subtract and Retain Solid
  • Subtract and Remove Solid
  • Create 3rd Solid from Common Volume of 2 Solids
  • Create Volume from Intersection
  • Remove Common Volume
• Extrude Along Path
• Loft
• Sweep Path
• Rotate
