Create a curve-on-surface
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.
