Accessing cad file data

[shehab_fekry]

I have a revit api project and I want to access the data from a dwg file, data like block names and attribute values i can only access geometry and layers in Revit api.

First of all, in order to use the AutoCAD api, you would have to have AutoCAD installed on the same pc. Do you?

Yes I do, i have added the dll files as references in my project, I want to access a document without opening it, I want to read some attributes from some blocks in the autocad document.
