shennig Posted March 4, 2015 Share Posted March 4, 2015 Hi everybody! Im looking for a lisp routine that will draw a polyline on a certain layer & then offset it both sides at a certain distance & then put those offset lines on a different layer. I have tried to create this but due to not really knowing lisp i have failed miserably. What i am trying to achieve is draw a HVAC flexible duct with a centreline to improve productivity. any help is appreciated cheers:D Quote Link to comment Share on other sites More sharing options...

BIGAL Posted March 5, 2015 Share Posted March 5, 2015 Search here for Duct there are numerous posts for drawing ducts, pretty sure one of the regulars has a suite of programs. Quote Link to comment Share on other sites More sharing options...
