Solid - 3D-General

Solids in the 3D-Professional Version are defined using boundary Surfaces and identified as 3D-General Solid. In one project, one can not use at the same time 3D-General Solid and 3D-Layered Solids (created in the 3D-Standard Version) or the parametric blocks (created in the 3D-Lite Version). It is, however, possible to convert 3D-Layered Solids into 3D-General Solid by changing the project type from 3D-Layered to 3D-General.

Boundary Surfaces of a Solid must enclose a closed space and cannot intersect each other. Interior of a Solid must form a three-dimensional “simply continuous space”, i.e., it must be possible to connect any two internal points using a polyline that is entirely located inside of a Solid. Boundaries of a Solid thus can be formed by any number of either planar or curved surfaces.
