Creating Combined Curves

Combine lets you create a curve resulting from the intersection of the extrusion of two curves.

This task shows you how to:


Before you begin: Create a 3D shape containing two curves.

Create a Normal Combined Curve

You can create a 3D curve by combining two planar curves lying on different planes. The virtual extrusion is computed as normal to the curve planes.

  1. Select Normal to curve .
  2. Successively select the two curves to be combined.
    The combine curve is the intersection curve between the extrusion of the selected curves in virtual perpendicular planes.
  3. Click OK.

Create a Combined Curve Along Directions

You can create a combined curve along specified directions. You need to specify the extrusion direction for each curve (Direction1 and Direction2 respectively).

  1. Click Combine .
  2. Select Along a direction .
  3. Successively select the two curves to be combined and a direction for each curve.
    The combine curve is the intersection curve between the extrusion of the selected curves along the selected directions, as illustrated here:
  4. Click OK.

Important: Select Nearest solution to automatically create the curve closest to the first selected curve, in case there are several possible combined curves.
