Sketch lose refences

Creator
Creator

Hello to everyone,

 

I am pretty new in NX and I have problem with sketch. First my sketch was green, I've added a dimension and unexpectedly becomes blue. You can see in the attached file. Then when I draw something, in one case NX gives me tangent constraint option and in other he doesn't. When I try to add constraint it lose references.

In second sketch, if I just add some circle sketch becomes overconstrained.

Can someone please explain me what is the problem?

 

Thanks in advance

I'm analyzing your movie. I think I can give you a solution - suggestion to the first problem.

In my opinion you have turned off the 'Create Inferred Constraint' option in sketch.

This is seen when you make offset curve and degrees of freedom increase from 23 to 67 (status line at second 54).

Ciao

p.s. I use often sketch in task environment and very rarely direct sketch.

For the second problem I saw that there is a dependency between Distance Measurement (10) and the Sketch (11). First try to suppress this features and look at the effects.

Thank you Cesare for your reply. But i still don't know why the sketch is blue and not green?

Best regards
