Create a curve at the intersection of two or more surfaces or faces. The selections must intersect.

In the Feature toolbar:

Intersection curve icon in toolbar

Intersection curve allows you to create a curve at the intersection of surfaces and faces.

Click the intersection curve feature from the feature toolbar. Select the surface or group of surfaces that intersect. A curve is created at the intersection.

Click the checkmark to accept the new intersection curve.

The benefit of this workflow is that it is faster than other workflows, such as using split, and the original surfaces remain intact.

Steps

With two or more surfaces or faces that intersect in the graphics area:

  1. Click Intersection curve icon.

    Intersection curve dialog

  2. Group 1 is automatically highlighted. A group is a collection of surfaces and/or faces from which intersections are created. Select the first group of surfaces and/or faces in the graphics area.
  3. Select Group 2 in the dialog.
  4. Select the second group of surfaces and/or faces in the graphics area.
  5. Click Accept checkmark icon to accept.

Intersections between entities in the same group do not generate a curve, only intersections between Group 1 and Group 2.

Depending on the selections for Group 1 and Group 2, more than one curve can be created.

Multiple Intersection curves example

An example where two intersecting surfaces result in the creation of 3 curves

Use the eye icon in the Parts (Curves) list to show/hide the curve.

Tip

  • If you create a Linear pattern from an intersection curve, the curves may not be created along the surface. If you instead want them created along the surface, open the Linear pattern feature dialog, add the plane used for the intersection in the Features to pattern, and check Reapply features.
