NX reference dimension in sketch
NX reference dimension in sketch
(OP)

I am trying to have the length of the lower segment changes as function of the upper segment. I don’t want to constraint the upper segment to any certain value but there’s a relationship I ‘d like to keep.
In the expression tab, I had the lower_length=upper_length+10, the problem is when I changed the upper_length, the upper_length variable doesn’t update.
It seems to me that NX records the reference as a constant and doesn’t keep track of the changes.
NX 10.

For your particular situation, I would suggest breaking your sketch into 2 sketches. The first sketch will define the upper line. Finish the sketch then create an associative measurement of the length of the line; this will create an expression of the line length (a reference dimension, if you will) that you can use to drive the lower line length in sketch #2. Not as clean & satisfying as having everything in a single sketch, but it avoids the situation that you are currently in.
