Purpose
Usage
Click the sweep accuracy input box to activate it, type in the required value
and press <enter>.
Comments
Computing the surface for a sweep from its defining curves is an approximation.
The smaller the value, the smaller the deviation of the approximating surface
calculated from its defining curves. Also the smaller the value, the larger the
number of control points used to define the surface. More points can result in
more rendering time.
A value of 0.0 or a negative value is not allowed (default is 0.15).
