Title: How to start Lisp with Civil 3D-Props?
Post by: Peter2 on March 17, 2017, 08:05:27 AM
I would like to start with usage of Autolisp in Civil 3D (objects, props, ..)

Are there some references which describes the (different?) ways of communication between Lisp and Civil?

Have a fine weekend?

Peter, no, there are no references specifically for lisp with C3D. If you search the Autodesk C3D Customization forum you will find a number of posts steering you away from lisp lisp to the .NET API. You will also find quite a few small lisp commands that I, and others, have posted. The C3D COM API reference has not been updated since C3D 2012 (http://docs.autodesk.com/CIV3D/2012/ENU/API_Reference_Guide/com/civil_om.htm), and some of the links in that are broken so some creative editing of the url is needed at times.

There are quite a few of the COM objects that you cannot get/set properties for due to lisp not recognizing the type of variable it expects. However, there is still a lot you can do in lisp. Here is what I currently use (posted by another user on the C3D forum, I do not recall who that was though) to get the AeccLandApplication for any version of C3D (you will need this to get any C3D object without using a selection):
Code - Auto/Visual Lisp: [Select]
  1. (defun getaeccApp (/ *acad* C3D)
  4.            (setq C3D (strcat "HKEY_LOCAL_MACHINE\\"
  5.                              (if vlax-user-product-key
  6.                                (vlax-user-product-key)
  7.                                (vlax-product-key)
  8.                              )
  9.                      )
  10.                  C3D (vl-registry-read C3D "Release")
  11.                  C3D (substr
  12.                        C3D
  13.                        1
  14.                        (vl-string-search
  15.                          "."
  16.                          C3D
  17.                          (+ (vl-string-search "." C3D) 1)
  18.                        )
  19.                      )
  20.                  C3D (vla-getinterfaceobject
  21.                        (vlax-get-acad-object)
  22.                        (strcat "AeccXUiLand.AeccApplication." C3D)
  23.                      )
  24.            )
  25.       )
  26.     C3D
  27.   )
  28. )
  29.

Thanks Jeff, I will look at it.

What are you trying to do ?

To give a couple of my examples.
Rotate multiple Aeccpoints
Contour style display via a toolbar rather than toolspace
Label styles via a toolbar

Thanks.

In the meantime I found this document:
http://images.autodesk.com/adsk/files/AutoCAD_Civil_3D_API_Developer_s_Guide.pdf

I will start to work with it to understand the basic and the "data-system". For further questions I will come back to the forum.
