I have a model in which out of numerous amounts of curves in the work space, I only want four. So i have curve 1 and cyrve 2 on mesh A, and curve 3 and curve 4 on mesh B. I will do meshintersect+splitmeshwithcurve+deletemeshface, hope that makes sense. Now i am working on a script in which rhino can detect curve 1 and 2 are on mesh A, and perform the intersection etc and this continues on with mesh B.
I originally secluded them by length but each model has different lengths and even range varies, so its not repeatable. SO for now i have settled on selecting these four curves out of the work space using get object and then performing the necessary tasks. BUT of course this is not preferred. Someone gave me advice on using coordinates ( creating bboxes round each curve, finding the centroid and then using either the x y or z coordinates to select the curves) but thats a bit of work for me, although im still looking into it. But for now this get object script i have keeps crashing Rhino, it works at times, and crashes most of the time. can someone check what exactly is wrong with it?
