Circle coordinates nominals in CAD not exactly matching with 2D drawing nominals

1st reason can be not exact model.

2nd reason - did you first alignment from extracted features?

This happens with all CADs.

there's no issue in alignment and references.

Version of Calypso?

File format of CAD?

I have never face this - only if model was not correct, but models from SolidWorks ( in SAT and IGES ) are correct once i extract key features for base alignment and setup.
Other extracted features are then ok.

How are you extracting the features out of the model? With define points?

With 'define circle on cylinder'

[[No...]]

Although it is probably the least likely cause, may I ask what kind of parts we talk about? If it's plastic or otherwise molded parts, they usually have draft angles and I cannot count the number of prints I've seen where even the designer wasn't able to hit the correct one of two edges (start or end of draft) in 2D dimensioning.

Hi,

 

I 've often this issue with nominals when I use points (distance beetween points, distance beetween point and other form...) when I whant to check the nominals on the cad I use only plan line circle cylinder...

We check machined parts.

No draft angles are there.

Hast du evtl. die Temperatur-Kompensation eingeschaltet und die Temperatur nicht auf 20° ?

Dann passiert sowas schonmal

Could it be rounding on the drawing? Are you able to validate the coordinate of the model by other means such as a CAD modeling software such as SolidWorks or CATIA?
