[Ch...] Posted April 9, 2021 Share Posted April 9, 2021 Does anyone know how to plot or give a visual of a free form curve? Can't seem to figure it out. Thank you in advance. Link to comment Share on other sites More sharing options...

Profile of a surface is what I use. The data needs to be associated with the CAD geometry, and you need to use CAD evaluation. Lots of options and methods , so state your goal for more specific guidance. I'm a novice at the Curve option but plenty of help on the forum.

[Ch...] Posted April 12, 2021 Author Share Posted April 12, 2021 Yep, I have a CAD model. I don't think you can do a free form surface w/out one. So far I have not been too thrilled w/ this feature. I'm not aware of anyway to get a visual plot of it after the program has been run, & I have my doubts on how accurate it is. Using various alignments and vector points (space points), I have verified that the CAD model is correct. I did the same - alignments & space points - to try & validate the free form readings & there is definitely a difference. The profile has no datum scheme so I made sure I clicked "No Datum Reference Frame" in the profile of a surface characteristic. I clicked best fit for both translation and rotation (no datum ref). And yet the free form surface is anywhere from 0.022mm to 0.041mm. The individual space points are all w/in a fraction of a micron, locational speaking. Kind of at a loss.

[Ch...] Posted April 12, 2021 Author Share Posted April 12, 2021 Okay I got it. The software was not calculating the nominals for the point spread correctly. I made my own point set and verified all the nominals and everything came out great. Also verified w/ the vector points I was checking to verify. So all the numbers jive. Just another Calypso quirk. Thanks everyone who tried to help. Appreciate it. Link to comment Share on other sites More sharing options...
