find intersection of a generic circle and angled plane below the surface

joedraper
Hi all, I am new to PC-DMIS (2021R1 CAD++) and have been working on trying to configure a measurement for a couple weeks now. I do apologize for my terminology ahead of time. This forum has helped tremendously with the other measurements for this part, however, I have not been able to find a post related to this special characteristic that can apply to what I am looking to accomplish.

I am looking for some advice regarding a special characteristic that I need to find the intersection measurement between a generic circle/cylinder (R=34.5) and -0.49 below the part surface on an angled plane of 10+/-0.5 deg from the center of the measured circle (R= 30.25). The whole part is in 3D space, but the SC i am looking for is shown in 2D (ZX) as a side view. (hopefully the pic is visible). ​ ​
​ ​
Ive experimented with different settings/methods for constructing lines, points, planes and generic constructions of cylinders/circles to try and program the needed measurement efficiently and accurately. I may be missing a step when trying to align the generic circle (34.5R @ Z-PLUS) to the smaller measured circle (which R=30.25) located below the angled plane. Another issue i have encountered is trying to create a stationary line from the center of the constructed circle intersecting at the desired measurement location (generic circle and angled plane intersection), in tolerance (0.49 +0.08/-0.02).

Please let me know if additional clarification. I am very grateful for any help and direction from the community Slight smile . Thanks in advance!

  • Yes, i can interpret it in 2D.
    So, the special characteristic i am looking for is located on the angled plane 4.25 units in the X direction from the left edge (where the end of the smaller circle is located) and 0.49 below the parts surface.

    I created a cylinder with R=34.5 (with the same origin as the smaller circle) with an intersecting line at -0.49 below the surface. At that intersection, i created a pierce point to identify the intersection on the angled plane.
    I could have very well overcomplicated this when trying to create the program for the 3D part, which is why i reached out to the forum.
