https://forums.autodesk.com/t5/net-forum/converting-app/m-p/1578084#M82435 We’re converting a VB 6 application to VB.net. The app returns blocks and layers from AutoCAD versions 2002-2006 and sends commands to Autocad. The files are opened by starting an acadapp and then using dbx documents. I’m new to AutoCAD (I didn’t write the existing vb6 app) so I’ve been reading this discussion forum to try and get an understanding of how to get started. I have been able to open drawings to retrieve block and layer information using interops, but I question if that’s the best way. I’ve also read a little about getting the information from the database, is that a better? Now that the app is being re-written, what is the best way to do it in VB.net, using interops, database, or another way? I’ve searched for books too but haven’t found one on creating a vb.net app that communicates with AutoCAD, does anyone have any suggestions? Thanks.
