Generate Avoidance Geometry

Introduction

CloudNC Generate Avoidance geometry is part of the CAM Assist for Fusion add-on suite.

Avoidance geometry blocks out portions of the stock that don’t need to be machined for the specified Fusion ‘Setup’ of a part.

These ‘blocked out’ portions (avoidance geometry) are different from fixture bodies. While fixture bodies MUST be avoided, the Avoidance Geometry is considered part of the stock and may be gouged in specific cases. For example, drilling a through hole may pierce the avoidance geometry but not the fixture. Fixture bodies also require clearance from any tool, whereas all roughing tools may touch the surface of the avoidance geometry.

The CloudNC ‘Generate Avoidance Geometry’ add-on (available from the CAM Assist panel) generates this geometry for you in just a few clicks.

Once generated, the avoidance geometry portion of the stock can be seen in the ‘Models → Bodies’ section of the Fusion Browser and is utilized in the ‘General’ tab of CloudNC CAM Assist (see below).
