Sketch problem in NX 7.5

Sketch problem in NX 7.5

Sketch problem in NX 7.5

(OP)
Hi All,

I have a sketch in NX7.5 which keeps over constraining too quickly when I add contraints. I have tested this by adding a completly seperate line with no inferred contraints, the sketch tells me I need 3 contraints. When I try this with another sketch that is working normally the sketch tells me to add 4 contraints, which is what I would expect.

The sketch giving me problems has a few offset curves, could this be the reason for the unexpected behaviour?

Anyone else come across this or have a fix?

Rich

Hi Rich...

This is a bit difficult to investigate without an example... Can you upload the partfile ( or create one showing the same behavior )

RE: Sketch problem in NX 7.5

Did you created the offset curves with the Associative box checked? This will imply that they don't need dimensioning or constraints.

Best regards,

Michaël.

Thanks Guys,

I understand about the need to have an example, not sure if I can post one due to intellectual property rights reasons.

From memory, when I created the offset curves it told me I only needed 1 constraint (the offset value) this seemed normal to me. I have tried to create another offset curve but could not find the associative box although I did have the inferred contrains toggle button selected.

Cheers,
Rich

I deleted a bunch of contraints and re-did them slightly different. Now when I add an unassociated line it asks for 4 contraints, so it looks like the sketch is working normally again!

Thanks for your time

Rich

If you can't post the file here on a public site, then may I suggest that you cantact GTAC and have them look at it as they're set-up to protect your intellectual propery.
