Offsetting Surfaces

Create a parallel surface or solid by setting an offset distance from a surface.

With SURFOFFSET, you specify the offset distance and whether or not the offset surface maintains associativity with the original surface. You can also specify the offset distance with a mathematical expression.

When you offset a surface, you can do the following:

• Change the offset direction with the Flip option
  
• Offset in both directions to create two new surfaces
  
• Create a solid between the offset surfaces
  
• If you are offsetting more than one surface, you can specify whether the offset surfaces remain connected.
  
• Enter an expression that will constrain the distance of the offset surface to the original surface. This option is only available if associativity is on.
