Intersecting Objects

You can intersect an object with another object.

This task shows you how to:

Before you begin: Open a 3D Shape containing curves and surfaces.

Intersect a Surface With a Surface

You can intersect two surfaces.

Select one surface as the object and another surface as the reference.
Click OmniIntersect .
Optional: Click Selection Sets: Swap to swap object and reference.
Select the Extrapolation Type for a temporary result curve that does not reach the surface edge.
The extrapolation is always done with respect to the reference.
Optional: You can click Go back to selection at any time to change the selection, define and use selection sets, or to choose another mode in the selector panel.
Click OK.
The intersection curve is created on the reference surface.

You can intersect a curve with a surface.

Select a surface as the object and a curve as the reference.
Click OmniIntersect .
Optional: Select Extend Curves for Intersection to extend the curve parametrically to find an intersection.
Click OK.
The intersection point is created on the curve.

You can intersect a curve with a curve.

Select one curve as the object and another curve as the reference.
Click OmniIntersect .
In the Intersect Result list, select one of the following options.
Optional: Select Extend Curves for Intersection to extend the curves parametrically to find an intersection.
The pick point when you select the curve specify the side of the extension.
Select Projection Direction: View to compute the intersection in the direction of the current view.
Click OK.
The intersection point is created on the reference curve. Additional points are created according to the selected Intersect Result.
