Creating a Net Surface

From the Creation section of the action bar, click Net Surface

.

Successively select one or more guide curves.

Click the profiles text in the dialog box and successively select the profile curves.

Note: All the curves selected as either a guide or a profile must generate the flow of the surface (in the U or V direction but not both). Thus, two curves selected as a guide, for example, must not be perpendicular to each other (1 in U direction and 1 in V direction).

The dialog box updates with the number of guides and profiles selected.

Note: The guide and profile you select first is identified as being dominant, specifying that the surface segmentation is based on these specific curves segmentation. Click on a Guide or Profile tag to let this curve become the dominant curve.

Optional: In the Net Surface dialog box, click <<Settings to access advanced settings.

Optional: Click Copy (d) mesh on surface, then click Apply.

Note: In the App Options panel, select Furtive Display

to be better able to analyze the result.

Copy (d) mesh on surface selected: The parameterization of the dominant guide curve and the dominant profile curve is copied to the entire Net surface.
Copy (d) mesh on surface cleared: The parameterization of the other selected curves is copied to the Net surface.

Click Selection>> , then Display>>, and information to show or hide the tags.

Click moving frame to show or hide the moving frame symbol.

The moving frame defines the profile's position along the dominant guiding curve.

To edit the moving frame, do one of the following:

In the work area, click the moving frame to change its type. You can right-click the moving frame to see all the available types.
Shift + click the moving frame to switch to the previous type.
Right-click the moving frame's center to display its context menu.
Drag a handle at the moving frame's center to move it along the dominant guide.

Click Apply, then click OK.
