Circular Plane

[AAP_CMM]

I want to measure a plane in a circular motion of a known diameter. I am using PC DMIS CAD++ 2011. Is this possible?!

Auto feature plane allows creating circular planes. Just select "radial" in the auto plane, enter the radius, and select only 1 row. Select also circular moves.
You can also use vector points with a copy / paste with pattern. Be carefull to moves between hits in this case.

AAP_CMM : are you in dcc mode ?
Did you look at the excellent post of AndersI below ?

In 2010 mr2, can the start and end angle of the circle (radius) path be edited?

There is no start angle or end angle for an auto plane. However, you can control where the first point is taken by setting the angle vector.

Autoplane, Select "Radial" under "Pattern", make sure the "Void detect" button is not pressed, set your number of rows, number of hits, and "Spacer".

Note that in that old version the "Spacer" distance will be used both for distance from center to first ring, distance between hits, and distance between rings. In newer versions there's the more flexible "TTP plane circle" strategy where (among other things) those distances are separated.

Another way is to go INSERT - SCAN - CIRCLE then select TYPE plane enter the nominals as required this option allows full contact or single hits.

HNATko : this method should work if you want to measure less than 360°.

If I had been reading this thread rather than fighting PC-DMIS, that would have been an excellent idea. Instead, I did a point, copied and rotated, and recalled the points into a constructed plane. I come from many years in the Calypso/U-Soft/U-Mess environment; this is not going to be easy...

Or set your origin to the center of your circle, use polar radius/ polar angle to enter point coordinates and then construct a plane
