Create a four-sided surface with continuity (Square)
 
 
 

Square creates a four-sided surface by filling a region defined by four intersecting boundary curves. The resulting surface can maintain continuity with surrounding surfaces depending on the options that you set. You can use a curve, isoparm, surface edge, or curve-on-surface as curve types for the square surface boundaries.

In order for a square surface to be created, the following conditions must exist:

To create a square surface

  1. Make sure the four boundary curves intersect.
  2. Select the four curves in a specific order (either clockwise or counterclockwise).

    The first curve you select sets the U direction for the surface and the second curve sets the V direction.

  3. Select Surfaces > Square.
  4. In the toolbox, click Show Manipulators to view the continuity indicators.

    Click the indicator on a side to set the requested continuity, or open the channel box and set the square surface’s continuityTypeN attribute (the numbers indicate the order you clicked the curves).

Maya will still attempt to create a surface even if it cannot achieve the requested continuity options.

Troubleshooting square surfaces

If a square surface fails to be created as you expect, you should check the following:
