A cap surface takes a closed planar curve and makes a trimmed surface. It's a shortcut to build a flat surface trimmed with a custom-fit edge and for solid models. It is useful for making a planar trimmed surface to fill the area inside a curve.
Note: You probably need to
extract the source curve from an existing surface or surfaces.
To create a Cap Surface:
- Select Construct tab > Surfaces panel > From Curves > Cap to display the Cap Surface dialog.
- Optionally enter a name in the Surface name field.
- Select a closed curve from the
Curve list, or click the
Pick Curve
button and select it in the graphics window.
- Use the
Move item up
,
Move item down
, and
Delete item
buttons to set the sequence of the curves in the mesh.
- Enter a Tolerance. This determines the accuracy of the approximation to the curves.
- Click Preview to display a preview of the surface in the graphics window.
- Click OK.
