Create a flat surface inside a curve
 
 
 

Use Surfaces > Planar Surfaces > Set Planar to create a trimmed surface using a flat curve or set of curves as the outline.

Fill a flat curve with a planar trimmed surface

  1. Choose Surfaces > Planar Surfaces > Set Planar.
  2. Click or drag a pick box around all the curves that define the planar surface or surfaces.

How does the layout of multiple curves affect the surface?

  1. Click Go.
    Note

    You can mix boundary curves of different degrees without affecting the resulting surface.

    Note

    The flatness of surfaces created with the Set planar tool is not automatically maintained.

What if...?

The curve I want to use is not exactly flat?
