Edit Points Mode

Edit Points mode is often misused by beginners.Try editing the source object first.

Edit Points mode gives the false illusion of being in control of theshape. Most of the time it is better to edit the parameters of source

objects using construction history.

The Truth About Curves

NURBS curves are the only real type ofcurve existing in Evolve.

Every curve creation tool uses NURBScurves as the bricks.

Each tool provides a shortcut for achievingspecific shapes easily without having to

work manually on points.

If you collapse the construction tree for anobject created using the curve tools, the

result will be an object comprised ofNURBS curve entities.
