smorales02 Posted August 22, 2008 Posted August 22, 2008 happy Friday everyone, I will do my best to explain the situation. I have a profile of a water line that shows existing grade ( which was brought in using a LDD surface and so forth,) than I drew in a water line trying to keep a minimum distance between the existing grade and top of my pipe. My question is, what would be a quick way of finding out the shortest distance between the pipe and grade. this way I can make sure that I kept my minimum clear all the way through the pipe. Not a major problem, but I just want to know if there is a way to verify what I did meets the requirements. Let me know if anything else is needed to clarify. Quote
Strix Posted August 22, 2008 Posted August 22, 2008 there's probably a more technical answer, but can you offset one on top of the other? Quote
smorales02 Posted August 22, 2008 Author Posted August 22, 2008 thats what I do to draw in my pipe, the only problem is that my existing grade is never just a straigth line.... Im gonna post a scree shot and explai a little more...give me a min Quote
smorales02 Posted August 22, 2008 Author Posted August 22, 2008 ok here is a screenshot of a portion of my drawing. The two blue lines are my pipe..what i am looking for is a way to find the length of the shortest magenta line. If this needs to be in the lisp forum feel free to move it. This line runs about a mile so I need a way to draw the magenta lines in between the red and blue lines than find the shortest one. What i did for this screenshot was just draw XLINES vertically from the endpoints of the red line than trimmed between the two... So im trying to find a quicker way of combining those steps.. Quote
lpseifert Posted August 22, 2008 Posted August 22, 2008 Maybe this will work for you... Compliments of Joe Burke, CAB and Vovka MinDist.lsp Quote
smorales02 Posted August 22, 2008 Author Posted August 22, 2008 Thats what i am after.. But I seem to have one problem. When I use the lisp and select the red line first than the blue line it gives me a different minimum line than if i would selcet the blue line first than the red.. shouldnt it be the same??? Also is there a way to have it give me the minimum Vertical distance, right now it draws a perpendicular line between the two... but thank you for the find cause this will save me some major time..
