[Mi...] Posted December 15, 2021 Share Posted December 15, 2021 Attached is a scan of a part I am working on. The 3 non scanned areas are Ears that protrude out from the center. The print calls out the Envelope req but with it not being a full circle Calypso will not give me the results. Im in need of a work around but Im coming up empty.. Help is appreciated...

[Ro...] Posted December 15, 2021 Share Posted December 15, 2021 Hi Mike, You can use a Minimum Circumscribed circle/cylinder for the MMC condition and a Maximum Inscribed circle/cylinder for the LMC condition. If it passes both of those then it meets the Envelope Rule. This is for an OD diameter, which this appears to be. You would do the opposite for an ID diameter. Maximum Inscribed for the MMC and Minimum Circumscribed for the LMC.

Both have same meaning one is default and other need emphasis, correct??

[Mi...] Posted December 15, 2021 Author Share Posted December 15, 2021 Yes it is for an OD Thats what I have it set up as. It passes GN but fails the GN. So I guess it does not meet E Req.

[Ri...] Posted December 15, 2021 Share Posted December 15, 2021 Please sign in to view this quote. For the newbies - just use OTE for MMC and ITE for LMC. Calypso automatically selects the correct evaluation depending on if it an OD/ID.
