Dynamic block - stretching equally with angled lines

[Anonymous]

Hi,

I have been having trouble making a dynamic block to stretch correctly based on a specified input value. I want to be able to have the distance equal to the value I type in and have it stretch simetracally on each side such in a way that the angles will bend symmetrical opposite of each other. When I put in a distancevalue of 12" or 16" it will make the distance wider or shorter than my input value. I tried using a distance multiplyer but still failed.

Please see the attached block.

Thank you.

I just played around with it a little and I'm getting close, however my stretch arrows are off when I stretch. Is there a way to fix that so the stretch arrows align perfictly in the corners?

Here is the revised block.

thanks.

I changed the parameter basepoint to midpoint and the stretch actions' distance multipliers to 1.  I also removed the '2nd' stretch from each parameter and added back a similar one that is associated with the end that doesn't have a grip.

I think You loose 1 stretch 🙂

Ah, I didn't notice that.  I used the block from his second post which doesn't have the horizontal stretch.

Thanks for all your help! This is exactly what I was looking for.
