checking a fixture using part CAD

[Jonathan S]

I have a check fixture for a stamped sheet metal part that I need to verify. It is designed to use a feeler gage around the edges to check the profile. I have CAD for the part but not the fixture. I do not have access to a 3d drawing program. What I would like to do is use the CAD to create points, offset them 3mm along their normal vector and then flip the vector so I can check the surface profile of the fixture using nominal part data. How would I go about this?

in auto features go to advanced and use thickness. Put in feeler size in theo.

Make sure you know what side matl is drawn on in CAD model, you may have to add or not.

i usually just measure a vector point and make my check distance enough to hit the feeler surface, dimension T and the deviation should be very close to 3mm ±0.05 (Ford tolerance).

Thanks. That's easy enough.

I prefer the thickness method. Some engineers have violent mental fits if they have to "figure" something out from a report.
