Can't dimension sketch

[Berserk]

Hello,

UGNX5.0.4.1\WinXP SP3

I created basic lines based on the edge of a part, then projected it in a plane.

Then I created a sketch and added all the lines to create a closed rectangle.

Now, whenever I try to dimension the lines, it won't let me.

When I am at sketcher, the lines are dark green, but when I click on a dimension icon, it turns dark red.

According to the help file, this shows that it is fully constrained. But when I click on the "show constraint" icon, it does not show any. Not even horizontal or vertical. I guess it is using the original curves as reference.

How do I break this association?

TIA

a couple thoughts.

> Maybe you just need to "add existing curves to sketch" to make them part of the sketch.

> Instead of creating basic lines on the edge of the part and then projecting them ...
I think it would work if you extracted the edge curves from the solid and then project them. That way they are associated to the solid.
But then I believe you will still need to do what I mentioned above

Actually the real question is; why didn't you just project the edges directly into the sketch in the first place and skip all of the extraction/copying steps?

As for not being able to dimension these curves, since they are derived from, and are still associative to, the edges of the solid you can NOT add any additional constraints, be they dimensional or geometric, since, by definition, they are already fully constrained, which they turning 'Dark Red' IS the visual feedback telling you that they are. And even if you could add a dimension, what exactly did you expect to be able to control by editing that dimension?

As to your question as to how to break any relationships, what is it that you're trying to do with these projected curves?

To an Engineer, the glass is twice as big as it needs to be.

Hello,

I am working in assembly and I just need the edges of another part as a rough reference.
I do not need it to be associative. I would like to adjust the width and length and positioning based on datum planes.

Thanks for the tip about projecting the edges. I have always extracted edges then project the resulting curves. Did not know/notice that you can project edges.

Try projecting the curves, converting them to reference and then create normal sketch curves constrained relative to them (Parallel, Perpendicular, etc.) and work with these in terms of editing their location and size.
