If you have ever tinkered with some AutoLISP program you downloaded from the Internet and thought "Gosh, what's this all about?" you definitely need this book!

AutoLISP is all about really controlling AutoCAD. If AutoCAD doesn't have it, I wont wait for them developers to add it in some future Release...  I'll make it up.

For example, I was fed up with copying one solid part so I could subtract it from another without losing the original. So I went to work and in a couple of days I came up with STRIM, The 3DSolids trimming App you can now download from Autodesk Exchange. Using it you can select a bunch of "trimming" solids whose volume will be subtracted from another bunch of solids selected to be trimmed. They say "time is money" and this tool I'm sharing with you all has sure saved me a lot of time.

Once I solved the trimming, I wondered if sometimes I would need not to TRIM the solids, but instead to SPLIT them in a way that all the portions overlapping would be split into separate solids.
So I put AutoLISP to work again. And here came SSPLIT, the other App I'm sharing.


But I don't want to keep the way it's done secret. I've been a teacher all my life and that's a thing I really enjoy. So if you wish to do things like this, then this books can help you. Be it in the Paperback edition or the Kindle e-books.

Hope you enjoy them. I look forward for your feedback.
