Maya
provides several techniques for creating a curve-on-surface:
Draw a curve-on-surface by placing edit
points
- Select the surface on which you want
to draw a curve-on-surface.
- In the Status Line, click the “Make
the selected object live” icon.
- Choose
Create > CV Curve Tool or
Create > EP Curve Tool.
- Draw a curve on the live surface.
- When the curve is finished, click the
“Make selected object live”
icon again.
Project
a curve onto a surface along the view direction
- Select a surface and one or more curves.
Select the objects in
a view pointing in the direction you want to project. For example,
if you want to project along Y, select the objects in the Top view.
- Select
Edit NURBS > Project Curve on Surface > and
set Project Along to Active
View.
- Click Project.
Project
a curve onto a surface along the surface’s normals
- Select a surface and one or more curves.
- Select
Edit NURBS > Project Curve on Surface > and
set Project Along to Active
View.
- Click Project.
Intersect
two surfaces to create a curves on surface
- Select two surfaces.
- Select
Edit NURBS > Intersect Surfaces.
The default is to create
curves-on-surface on both surfaces. To only create curves-on-surface
on the first or second surface, open the option box (
Edit NURBS > Intersect Surfaces > ) and
set the Create Curves For option.
Notes
- If a curve on surface has been created
using project curve or intersect surfaces with construction history
enabled, performing delete components on such curves before deleting
construction history may create data loss when saving into a file.
Delete construction history before deleting components.
