Dynamic Block Stretch Problem

Anonymous — Fri, 22 Feb 2019 14:47:50 GMT

I am trying to create a dynamic block of a curtainwall frame that I can place onto a 3D skeleton building elevation. The frames will vary in height, and the vertical members will be skewed at various angles (see attached files). Basically I want to place the block onto the elevation and snap the four corners to points on the skeleton. I also need to move the intermediate member up and down.

The problem that I am having when I test the block is that depending on how I stretch the frame the grips will move away from the frame corners as it becomes a parallelogram.

How can I stretch it and keep the grips at the corners?

Thanks in advance.

I've tried to get this done and 2 troublemakers when put together in this case are (1)Intermediate Member (2)Constraints. I would suggest to make 2 different blocks.

Thanks for looking at it Salmanul. Two blocks isn't really an option for me. I think when I get back to work Monday I am going to modify it by adding two angle parameters in the lower corners with a list of angles and see how that goes.
