Use the Extend Lines context to make an existing line longer, following the general vector and/or curvature of the
input line. You can specify the distance as a numeric value, or extend the line to a specified node, line, surface,
or point.
A surface represents the geometry associated with a physical part. A surface is a two-dimensional geometric entity that
may be used in automatic mesh generation.
Solids are closed volume of surfaces that can take any shape. Solids are three-dimensional entities that can be used in
automatic tetra and solid meshing.
