Hi Everyone

First time posting on here, I hope you guys can help me out. I'm fairly new to PC DMIS and I'm stumped on the best way to measure the distance from one plane to another angled plane at a particular gauge height called out. The attached sketch is representative of the drawing.

I would measure two vertical planes and one horizontal plane. Horizontal plane I would use to create offset plane in 3.0 height then intersect vertical planes with offset plane. Result will be two lines in height 3.0. DIM "A" will be distance between lines. Instead of planes can be used lines, then result will be distance point to point.

I'm not sure what the part actually looks like from this. There are plenty of different ways depending on the features involved. You could offset a plane up the basic distance from a copy of the bottom plane. Or level and origin to the bottom, offset the alignment up the basic dimension, then create an alignment plane. Alignment planes are workplane dependant.
Then intersect the new plane with the angled plane and distance to the intersection.

Measure point on right hand wall at 3.0 from bottom

Measure left hand wall to find angle.
Measure point on left hand wall, approaching at angle vector at 3.0 from bottom.

Report distance between points.

Measure point on left hand wall, approaching at angle vector.

Report distance between points.

The problem with that is if the angled wall is off "location" at 3.0 up, the probe will NOT touch at 3.0 up and give a false return.

The problem with 3 planes and intersecting lines and distance between lines is that it won't work either if there is any angle deviation to either side wall (in the direction of the picture), you won't get the correct value either.

Plane on the bottom
Plane on the right
Plane on the left
Plane constructed 3.0 up from bottom plane
Line intersection of 3.0up plane and right plane
Line intersection of 3.0up plane and left plane
Plane on FACE
Plane on REAR
Intersect both lines with both front/rear planes
2-D distance between 'rear' points
2D distance between 'front' points

Thanks Matthew, that worked like a charm!
