Read DWG/DXF FILE DATA IN ASP.NET WEB APPLICATION
In general, there are 3 ways to create/edit data in dwg/dxf files:
1. Using AutoCAD , the desktop application, itself. Since you are doing web application that runs in an unattended server, this would not be a viable option. However, you may consider use AutoCAD's accoreconsole.exe, which comes with AutoCAD installation.
2. License Autodesk's RealDwg technology/SDK, which enable you to access data in drawing file without using AutoCAD. The license is a bit expensive, but if your web app deals large volume of drawing file, the cost would be justified.
3. Use Autodesk's Forge Cloud services. Since you are doing web application, this would be the more suitable way: it only costs when the service is used.
Whichever way you choose, you, or someone working with you must know how to deal with AutoCAD drawing database (acdbmdg.dll) very well.
