Keyhole dimension questions

[[Mi...]]

Not actual part, just image off the web. Cannot show print.

1)   Drawing has a true position of the small diameter, I created a cylinder and when I generate the Position it shows a 7mm deviation in the results. The cylinder diameter and X.Y location are less than 50 microns off. 

 

2)  How to get the radius to radius dimension? (blue arrow)

 

Thanks

For TP i would suggest Geometry norm.

For that distance - there can be many ways:

• line from centers of those two circles - then intersection line/circle with mode: curve
• section - then two touch point ( disc ) on selection and projected on section instead of mesh

Thank you,

 

Did not know Geometry was an option. For the distance I used the second option, not familiar with curves in GOM Inspect, I do use curves all the time in Calypso so I'll have to spend some time learning them with Inspect
