Revolve with Rail
This is not simple to understand, but very useful for many shapes and
creating tents.
Complex NURBS surfaces can be created by revolving a prole along a
guide curve (rail).
The Revolve with Rail command creates the NURBS surface by revolving a
planar NURBS curve about an axis. The revolution is guided by a rail curve
on a plane perpendicular to the plane containing the prole curve and axis.
To create a NURBS surface with prole and rail:
1.
Create an axis, rail and prole out of NURBS curves.
The axis must be a linear NURBS curve•
The prole must be a planar NURBS curve•
The prole cannot intersect the axis, though it can touch•
The axis must lie on the same plane as the prole•
The rail must be a planar NURBS curve perpendicular to the axis •
and prole
2. Select Model > 3D Power Pack > Revolve with Rail
. Select, in
order, the axis, prole and rail.
3. The NURBS surfaces are created.
