Q - question

How to convert a solid body to a surface (3D faces)?

A - answer If you need to convert a SOLID to its surface representation consisting of 3DFACEs, you can use the conversion to Mass Element in AEC versions of AutoCAD.

AutoCAD Architecture, AutoCAD MEP and AutoCAD Civil 3D contain the command MassElementConvert (or its quite different version -MassElementConvert), which converts a solid body to a mass element. This mass element can be then exploded to a block reference then to the individual 3D faces. Smoothness of the resulting surface is controlled by the FACETDEV variable.

So, to convert a 3D solid to 3D faces, us the sequence of commands MassElementConvert, EXPLODE, EXPLODE.
