How to convert a body object to a 3D solid

Instructions on how to convert a body object, such as polyface mesh, to a 3D solid in AutoCAD. These objects are not able to be edited by core 3D commands.

1. Create a layer to place the body object on and isolate that layer.
   • Isolating the layer can either be done via the Layer Properties Palette or by using the LAYISO command (see link below).
2. Type FACETERSMOOTHLEV and set the variable to 0
3. Execute command CONVTOMESH and select the "body" object. When prompted, click Create mesh.
4. EXPLODE the new object to 3DFACE objects
5. Execute command REGION and select all 3DFACES. Don't use union on regions (there are circumstances where you can but there is no need for this in this process).
6. Execute command SURFSCULPT (not CONVTOSOLID) and select all regions
