Calculating Region Intersections

A feature of SVOffice™ 2009

June 6, 2011

SVOffice™ 2009 supports overlapping geometry, but complex 2D models may benefit from non-overlapping geometry. SVOffice™ 2009 includes a tool to make this operation easy. It operates in one of two modes: an automatic mode that attempts to generate all non-overlapping geometry, and a manual mode that provides tools for determining intersections, unions, subtractions, and exclusive-or operations. The manual mode includes settings to generate new regions, modify existing regions, and to remove clipping regions after use.

The following model demonstrates a sample case. Note the highlighted region geometry in red:

Use the following steps to access this feature:

• Open the model to be modified,
• Select Model > Geometry > Tools > Intersection...,
• Use the Automatic tab to auto-generate region intersections, or
• Use the Manual tab to access detailed functions for intersection, union, subtraction, and exclusive-or,
• Adjust the options on the Manual tab to generate new regions, modify existing ones, and remove clipping regions after use.
