Title: Special Lisp-functions for Map 3D - experiences?
Post by: Peter2 on May 23, 2019, 05:31:45 AM: Digging deep in the lost times of dinos I found a documentation for spec

https://knowledge.autodesk.com/de/support/autocad-map-3d/getting-started/caas/simplecontent/content/map-3d-documentation.html

The ZIP for version 2012 contains a CHM (basically written in 2007) which describes some features. The sample-code for "map_dwgbreakobj" worked fine in MAP 2018.

Who has experience with this package in current versions?
Does it work fine (on Oracle based data)?

Why AutoCAD quit providing help for these functions I'll never understand.

great link.

I'm just beginning with map, but when I look at all the different blogs which had the last post in 2012/2013, then I think that theq quit more than the Lisp-documentation :-(

Autodesk has stopped providing help for LISP in Civil 3D / MAP because :-
(a) LISP is outdated for them and no further developmental work is going on in LISP. Similar is case of VBA.
(b) Autodesk wants to focus on dotNET (.NET) programming because it is the most common platform nowdays. Although I don't think this is a wise idea because the number of developers on LISP must be 1000 times the number of developers on dotNET for CAD Products.
(c) LISP has many limitations such as limited graphics, no multi-tasking, limited capability to interact with external software etc.

This topic is now approx. 20 years old, and still only partly correct. As we all now - and you mentioned it above - " ~~Punk's~~ Lisp is not dead" now, and the old advantages are still the current advantages. Nevertheless, we won't change it.

Have a fine weekend!

Post by: snownut2 on July 11, 2019, 03:14:00 AM: Peter2 I have to disagree with you. We are changing it, Bricscad is actively developing lisp and will cause AuTODESK headaches in their user base. By the time they figure it out it will be to late.
