Dynamic Block stretch not working

[riley.hillW59LM]

Hello,

This is my first time creating a CAD block and can't seem to get it working.

I have created a block where you can enter the diameter and wall thickness of any pipe. (this part works)

But when I go to stretch the block it does not work. It only stretches 4/5 of the lines after a certain length. If anyone knows how to fix this it would be greatly appreciated. It works fine if I enter the length manually but if I use the snap point it only does 4/5 of the lines.

It's because of the constraints. It's best not to mix constraints with dynamic parameters/actions and there is no need for any constraints in this block.  See attached.

Thank you for you quick response, works great

How did you get the THICKNESS parameter to do both sides?

I added a move action for each of the lines, then selected the move action for the bottom line and changed its angle offset property to 180.
