As the saying goes 'Your results may vary.' I suppose there is a chance that this lisp routine will solve your problem all by itself. If you look at the bottom rectangle on the right you'll see a single magenta boundary that surrounds the two merged hatch patterns. Result is shown below in green.įinally, used a lisp routine called Hatchb.lsp written (03-30-2000) by Jimmy Bergmark that recreates a hatch boundary. Used a lisp routine by forum member hmsilva that he graciously wrote and shared on the AutoDesk Community website and posted to the Visual Lisp.forum on 04-12-2013 to merge the two patterns. Two boxes created with the Rectangle command which I hatched then moved the two hatch patterns to the right assigning each a different color (yellow and blue). I think I might be able to help but you will have to change the lisp routine you are currently using to merge your hatch patterns and adopt a second lisp routine that will create a single boundary.ĬAVEAT: I've only tested this technique once using nearly square hatch patterns.
