Dynamic block idea

I made this dynamic block that I use for adding snow load to roof plans, but had to take some info off because it belongs to the company, but you get the idea.

I needed to stretch the triangle to get the scaled length and wanted to array the arrows (12" spacings) with it. However, the arrows had to be scaled down so they didn't overshoot the hypotenuse of the triangle. I couldn't get that to work so I settled for moving the arrows at 1/12, 2/12....etc, the distance parameter.

No question here, just the idea may prove useful.
