Creating Combined Curves

You can 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. From the section of the action bar, click . Combine
  2. Select Normal to curve .
  3. 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.

    This illustration represents the virtual extrusions, allowing the creation of the intersection curve that results in the combine curve.



  4. 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.
