Boundary Surface

The boundary surface feature lets you create surfaces that can be tangent or curvature continuous in both directions (all sides of the surface). In most cases, this delivers a higher quality result than the loft tool. Consumer product designers and others who require high quality surfaces with curvature continuity can use this tool.

Direction 1 and Direction 2 are fully interchangeable in the PropertyManager. You achieve the same results whether you select entities using Direction 1 or 2.
Examples of boundary surfaces:
Single curve to a point in one direction Three curves in directions 1 and 2

To create a boundary surface feature, click Boundary Surface (Surface toolbar) or Insert > Surface > Boundary Surface, set the PropertyManager options, then click .

  • Curve callouts colors match those used in the PropertyManager.
  • Click callouts to change the Tangent Type.
  • To change the display color of the surface while you are editing it, use the System Options - Colors page to edit the color for Temporary Graphics, Shaded.
