3sides

Creates a surface blended between three boundary curves. Curves must intersect at their endpoints and determine an enclosed region.

How to use

1. Click the 3sides icon or choose the Tools > Surfaces > 3sides command.

2. The program console prompts Pick curve #1.

3. Pick the first curve that will be used as a boundary of the surface. Once picked, the curve turns green.

4. The program console prompts Pick curve #2.

5. Pick the second curve making sure that it is consecutive to the first one, i.e. the first point of the second curve should coincide with the last point of the first curve.

6. At the program console prompt Pick curve #3, pick the third curves.

Note: The Construction Tree allows you to modify any boundary curve only if intersections between curves are respected. If you move the middle points of a curve, the 3sides surface will automatically be updated.

If you move the start/end point of a boundary curve you will have to adjust the end/start points respectively of the other curve, in order to restore intersections. The three boundary curves should always determine an enclosed region.

Options

Curve #1

Curve #2

Curve #3

To replace a boundary curve.

Views / Modeling Tool panel. Switch the Replace check button on and pick another curve in the scene. The 3sides surface will automatically be updated if start and end points of the new curve intersect with the other boundary curves thus determining an enclosed region.

Type of interpolation

To set the type of interpolation to be used to generate the surface.

Modeling Tool panel. Switch the chosen radio button on. You have two options: Bilinear and Bicubic.
