This registry entry determines the conical tolerance for added tip changes. This allows PC-DMIS to utilize a tip that has a shank vector that is within the tolerance of the optimal vector angle for a given feature.
Entry Name: ConicalTolerance
Entry Type: Real Number to specify an angle. The default value is 5.
For features such as points, lines, and planes, there is a built in conical range of 90 degrees since a plane with a vector of 0, 0, 1 could be measured by T1A0B0 or T1A90B0. In the case of these features, PC-DMIS adds the user-entered value to the built-in range. The proposed tip angle is also checked by running collision detection (silently) to determine if the tip will actually work.
