Definition

The Intersect routine determines the characteristics of the intersection of two selected features. In conditions where more than one possible solution is identified, the user will be prompted to choose the solution.

Applying Intersection

The Intersection routine creates a compatible feature from the two features selected. The chart below outlines possible solution between pairs of features.

Notes Solution items marked in BOLD requires that both features must share a common Part Coordinate System.

Validity Rules

An intersection performed on a pair of 2D features requires that both features share a common Part Coordinate System and a common PCS Base Plane. For example, two XY Lines both in PCS #1 would be valid for intersecting. However, two 2D Lines one in the XY base plane and the other in the ZX base plane would not be valid for intersections.

Special Intersection Applications

In some cases, the intersection command results in multiple solutions. Geomet provides special tools to assist in choosing the correct solution you require. To see these tools, select from a feature combination below.
