I have a part that needs to dynamically change shape if the height changes. I have a horizontal bar that a bracket is mounted to and I have another surface that needs to be able to go up and down depending on what value I need the height for that one. When attachment 2 is below attachment 1, I want one line to have a minimum that it will go down above the top of attachment 1 point so the bracket doesn't get too weak. However, if I go up, I want that top linked point to go up with the top of the bracket so that it gives it strength as it goes up.

As an example, here is a low position.

If I move the Attachment 2 to the high position I can keep the top of the line above Attachment 1 at the same height like this pretty easily

However, I want it to do this instead only if the Attachment 2 goes high Notice the new line at an angle.

Is there any way to use an IF/THEN statement or some other way to allow this to happen automatically in the background? I suppose this might cause a Topographical Naming Problem though if the number of surfaces change.

* You should do 2 sketches (and 2 pad/pocket): 1 for static lines, 1 for modifiable lines.
* 2nd sketch need to always have the same number of lines (TNP - no refine)

No if/then but ternary operation.

I would have never thought to do that. I have the two sketches linked to a spreadsheet and I can use the If/Then there to adjust the length of the one segment to stay near 0 or increase as it goes higher. Not a pretty part, but at least it doesn't break now.
