Framework:Blending

The ACIS Blending Framework comprises two components (Blending and Advanced Blending) which facilitate the creation of smooth blend surfaces and chamfers in order to replace sharp edges and vertices in a model. The ACIS Blending Frameworks allow creation of rolling ball, variable radius, entity-entity, three entity, curvature continuous, and holdline blends. The surfaces in this framework are generally ACIS procedural surfaces except when analytic representations are possible.

Component	Description
Blending	The Blending component (BLND) allows the creation of blends and chamfers on sharp edges of a model. Standard Blending allows the creation of Constant Radius Blends Variable Radius Blends Chamfers
Advanced Blending	The Advanced Blending component (ABL) allows the creation of more complex blends and chamfers than the standard ACIS Blending component. Advanced Blending allows the creation of Entity-Entity Blends Three Entity Blends Curvature Continuous Blends Advanced Chamfers Holdline Blends Variable Radius Blends With Advanced Features

• ... create blends without losing features contained within the blend sheet
• ... create curvature continuous blend surfaces
• ... create full round blend surfaces

Some of the ACIS R20 improvements are:

• The behavior of Blending on tolerant parts has been made more robust especially when rollover/rollon and capping are involved.

• Blending APIs provide additional diagnostic information as part of their outcome. This would potentially give some more clues to identify the problem zone.
