VB6 - Extract attributes

I'm making a project in VB6 and i don't know what i need to import data from acad¿?

can somebody help me?

thanks in advance

 

You can work with the drawing attributes directly from VB6 code.
1. Get your AutoCAD Application object using VB functions CreateObject() or
GetObject().
2. Set your ACAD ActiveDocument object.
3. Build a selection set of drawing objects (usually block references) that
contain the attributes you want.
4. Step through the objects in the selection set with a For Each loop.
Check to make sure the object has attributes using it's HasAttributes
method. If so, gather the attributes into an array using the object's
GetAttributes method.
5. Step through the array to read the attribute's TagString property (it's
name) and TextString property (it's value). Update the TextString as
necessary, or store them to a database, or whatever.
6. Do your cleanup and release your objects.

That's the sketch. Details and examples are in the help files. Ask more
questions when you are ready.

 

hello,

in the second step you wrote "ACAD active document Object"

i would try to do without open the AutoCAD only selecting a DWG , is this possible?

thanks

Browse through this site:
http://www.opendwg.org/

And run the terms "OpenDWG" and "Open Design Alliance" through your favorite
search engine. You may find what you are looking for.

 

Please post how it went m0nz0, your post read my mind. i'm in the same boat and it would be nice to know if its even worth getting into?

 

I am confused John I did not find any such code examples?

 

Did I say you would find sample code? Open Design Alliance produces
libraries and utilities that can be used to read/write .DWG files without
the presence of AutoCAD. There would probably be sample code in their kits,
but you will need to explore that yourself. If you have AutoCAD installed
on your target machines, but just don't want to open it in order to read the
attributes, then look into the ObjectDBX, which is supplied by Autodesk.

 

Extracting from a DXF with VB is pretty easy if you can use dxfs instead of dwgs.
