Cross Extend Surfaces

Use the Surfaces: Cross Extend tool to extend surfaces to meet each other, or other target surfaces.

Disconnected surfaces on the same plane cannot be extended using the Surfaces: Cross Extend tool.
  1. From the Geometry ribbon, Create tools, click Surfaces > Cross Extend.


    Figure 1.
  2. Optional: On the guide bar, click to define cross extension options.
  3. Select the source surfaces.
  4. If the Choose targets option is selected, click the Target selector on the guide bar then select the target surface(s).
  5. Extend surfaces in the following ways:
    • Click Extend on the guide bar.
    • Left-click a selected surface.

Access
Go to Geometry > Surfaces > Cross Extend.

Options

Define using
Select whether to extend surfaces by a thickness multiplier or by a maximum distance.
Thickness multiplier
Change the thickness multiplier to extend surfaces.
Distance
Change the maximum distance to extend surfaces.
Minimum angle
Change the minimum angle to extend surfaces.
Maximum angle
Change the maximum angle to extend surfaces.
Maintain edge angles
Do not change the angle of surface edges during extension.
Allow shortening
Shorten edges, within the extension tolerance, so that edges meet.
Extend as new surface
Create extended edges as new surfaces rather than a continuation of the existing surfaces.
Choose targets
Enable target surface selection.
