Hi,
I am trying to read .DWG file through VB, scan all the 2D and 3D. Looking for some sample code that works for both Model Space and Paper Space. Thanks in advance.

You can go about a few ways. To search everything, you can look through the Block collection. It includes, ModelSpace, PaperSpace, and BlockTables. If you are looking for certain "types" of entities, you can use the AcadSelectionSet to narrow your search based on entity parameters, and then search through those "found" entities.

Here is what I am trying to do:
I have .DWG (from mechanical desktop)files that have both 3D & 2D entities in them. not able to export(step or iges) the complete data out of Mechanical desktop. If I use step, I am losing 2d drawing data. If I use IGES, i am losing 3d data.

I would like to: (through VB )
scan all the .DWG files. If 3D entities are found, export them into STEP. If 2D entities( pure 2d drawing )are found, export them into IGES 2D.

If someone has some sample code for searching entities both in ModelSpace and PaperSpace, please post it here.

If you have some other ideas, please share with me.
Thanks in advance.
