nurbs mode menu

solid

Purpose
To determine whether the interior of a Nurbs model that is closed in at least one direction is solid or empty (surface only).

Usage
Click the solid button to activate or deactivate it.

Comments
If this toggle button is not active, the Nurbs model is an empty shape, like a balloon. When this toggle button is active, the inside is solid and can be modelled (subtracted).
The model should be closed in at least one direction (like a tube), or in both directions (like a balloon).
