"Equal" constraint overdefines sketch?

[Anonymous]

I have come across this problem numerous times. I solved it by dimensioning one side, and then setting the other dimension to equal the first by clicking the first. This only works if you're directly defining the dimension — in many cases, I want dimension B to be equal to dimension A, but dimension A is defined by other entities in the sketch, such as projected model geometry.

I am a Solidworks convert. This would not be over-constrained in Solidworks. I am trying to make the hole in the A and the O equal width. I can drag them horizontally, but I can't set them "equal". Any idea how I can set them that way?

Thanks!

There should not be any problem setting an Equal constraint between two entities, such as a projected geometry and another geometry, so long as it does not overdefine.  One thing I noticed in your screenshot is it looks like the preview/beta color indication of sketch constrainment is turned on, as indicated by some lines being black and others blue.  I would suggest try turning this off in Preferences under the Preview section, since it has been known to have some overconstraint bugs associated with it right now. 

Otherwise I can't really tell from the picture what might be going on, but if you could share your model, such as by exporting the .f3d file and uploading on this thread, that would be great.
