[To...] Posted January 14, 2020 Share Posted January 14, 2020 I thought I had posted this question before but can’t find it. Any suggestions for how to set this up in Calypso?

[Ja...] Posted January 14, 2020 Share Posted January 14, 2020 Could you check the runout to the secondary datum while making sure that it is constrained to the primary datum in the evaluation settings?

[An...] Posted January 15, 2020 Share Posted January 15, 2020 LSC,MCC,intersection point,constraint to datum or not. The result of total runout is always the same. Regarding the plane,not the cylinder. See attached.

I believe you trying describe the top view below but I feel the bottom view is correct, but you failed to explain how to use 2 datums in a characteristic that only allows 1 datum in Calypso.

[Ch...] Posted January 15, 2020 Share Posted January 15, 2020 Tom, I have this on a lot of our parts. What works for me is : Constructing a 'Perpendicular'. Perhaps Calypso should consider allowing an axial and radial datum inside a runout characteristic. This should work for a circle and plane or a cylinder and plane. Be sure to select the correct runout evaluation of course, axial or radial. Let me know if this helps.

[To...] Posted January 16, 2020 Author Share Posted January 16, 2020 Please sign in to view this quote. I like the concept of using an OTE cylinder as the Primary datum feature, with it constrained to an OTE plane. Thank you Phillip. The problem with using a Perpendicular construction (remember, from the mid-point of Feature 1, perpendicular to Feature 2), when you select the cylinder as Feature 1 in order to get the mid-point of the axis, you can't select a plane feature for Feature 2. If you reverse the order, it works but the 3d line it constructs is from the mid-point of the plane, perpendicular to the cylinder axis. It does work with a circle as Feature 1, but then you lose the ability to capture the Virtual Condition cylinder.

[Lu...] Posted March 31, 2020 Share Posted March 31, 2020 Please sign in to view this quote. Hello, i have a similar problem with runout to A/C .For example 0.01/A/C. A is a plane. C is a Cylinder. I always create Perpendicular construction. But this method works when i select first Cylinder and second plane. It is correct?
