I have provided a list of some useful Lisp resources previously here: The Cadalyst website has for many years been a repository of custom lisp routines provided by users which are available to download to use or to learn from. This includes tedious tasks like creating custom hatch patterns.
AutoLISP, despite being an older environment, can perform many popular tasks. I usually see the questioner switch off at this point and mentally write off the custom hatch issue as not being possible, but hang in there, we have an easy solution!įor many years AutoCAD (and now AutoCAD LT 2024) can achieve tasks via its API. We must plan out a series of lines and points on paper or in our head, and type it out into a text file, save it with a PAT extension and then add it to our drawing or template file. The answer is, the process is a little clunky. not just ones with parallel or crosshatch lines but ones with more bespoke arrangements. A common question I receive when training AutoCAD at various levels is, how easy it is to create complex custom hatch patterns? i.e.
