Stretch of diagonal parallel lines

"How to correctly apply stretch X, Y in a dynamic block to maintain a constant distance of 50 mm between two diagonal parallel lines?"

[j.palmeL29YX]

For a first attempt I used the dimensions given in your example file.

OK, thanks for the help, but unfortunately, that's not what I meant. This example is just a snippet of a larger object. I need to use stretch. I tried combining the Stretch function with bindings, but it ultimately falls apart.

Then next time please start with the complete context instead of adding context/rules after someone helps you.
Unfortunately you cannot do this with normal stretch actions.

Maybe it's possible in combination with move actions/point parameters but it would be very difficult.
