This command creates a curve that is offset f rom
a curve that lies on a sur face. In other words, the
parentcurvemusthaveoneofthefollowingtypes:
surface-surface intersection, U iso, V iso, normal
projected, vector projected, CV curve on surface,
or point curve on surface. The offset is normal to
the sur face. T hat is, the new curve is either above
or below the surface by the offset amount.
Creating surface offset curves
Procedure
To crea t e a surface of f s et curv e:
1.
In a NURBS object that contains at least
oneNURBSsurfacewithacurveonit,turn
on Create Surface Offset Cur ve in the NURBS
toolbo x, or Surf Offset on the Create Curves
rollout.
2. Put the cursor over a curve that lies on a surface,
and drag to set the offset amount. Release the
mousebuttontoendcurvecreation.
