Efficient modelling seems to depend a lot of selection of start point and sequence of actions. This is exercise 6.118 from Giesecke F.E., Mitchell A., Spencer H.C., Hill I.L., Dygdon J.T., & Novak J.E. (2014). Technical Drawing. Upper Saddle River (NJ) USA: Prentice Hall I have been pondering where to start and what to do for quite a while now and I don't see any clear favourite. Where would you begin? ... and Why?
jeremyearle5 posted a topic in AutoLISP, Visual LISP & DCLI need to know how to get the start and end points of a polyline. I'm a rookie at this and just learned how to pull out the start and endpoints of a line and when I went to do it to a polyline I was completely lost. Another question: I use a comand that takes a line and turns it into a perforated line with each segment being a separate poly line. It creates them all in order down the line. Immediately following this command, would there be a way to call the first poly line created to extract its data, without manually selecting it?
