[Ma...] Posted October 24, 2019 Share Posted October 24, 2019 I am increasingly seeing the Envelope requirement appear on our companies drawings. (Letter E in a circle) My understanding is that this requirement is a combination of several other GD&T elements, is there some way of reporting dimensions to this requirement in Calypso TIA Link to comment https://qualityforum.zeiss.com/topic/17302-gdampt-envelope/ Share on other sites More sharing options...

[He...] Posted November 9, 2019 Share Posted November 9, 2019 In the characteristic 2-point diameter there is a radio-button for Envelope condition. This will make Calypso evaluate (for a hole) the maximum 2-point diameter as max-value and maximum inscribed cylinder (or circle) for the min value. For a shaft it is the other way around. This is not a perfect approach since it will only evaluate 2 point diameters from the same circle path but for machined parts it should be fine.
