Editing ARX Objects with AutoLISP????

[bdwidhalm]

Does anyone know how to edit custom objects (ARX) with an AutoLISP routine? I can give more specifics if needed.

The company I work for have their own software add-on they developed for joist and deck. However it is lacking a few simple editing features such as moving some text from one side of the object to the other side. In order to accomplish this users have to select the object, open the properties and select the choice from top to bottom. They have that available through properties so I was wondering if there is a way AutoLISP could access it and change it??? I can obtain the object entity info and I know that the dotted pair (292 . 1) represents text on top and (292 . 0) is bottom. I've tried doing an entmod but it always comes back nil.

I was wondering if entmod won't work on custom objects??? Or if I just need to go about this another way.

Any thoughts would be great and if you'd like more info or graphics I can get those too.

Thanks.

You may be able to use VisualLISP to modify the object.

Seeing as your custom object shows its properties in the Property Palette, this might just work. Type the following 3 lines at the command prompt & select the object when asked:

(setq en (entsel))
(setq eo (vlax-ename->vla-object (car en)))
(vlax-dump-object eo t)

Press F2 to open the text screen - it should display all the available properties / methods on that object. From there you can then figure out which to call using (vlax-invoke-method eo ...) or (vlax-put-property eo ...).
