See attached image. Does anyone have a lisp routine that draws turning vanes in the corner of the ductwork? Right now I am using a dynamic block and I would like to cut out the steps of having to stretch the vanes manually. What I would like is for the user to do it in 3 clicks. 1) Select the button to start the lisp. 2) Select the inside corner of the duct. 3) Select the outside corner of the duct. And the rest would automatically draw it in. The only requirements would be that the routine draws these lines on a specific layer and they are yellow. The other requirement is that the 2 lines not dashed are 3" offset from the inside corner of the ductwork. I've searched on augi for this lisp routine but I can't find any posts related to it. I have also googled it and again found very little info (unless I want to pay). Thanks in advance.
