问题
I am expoloring currently an AutoCAD .NET API to create a dwg files from winform. Is this possible or should I look for another library? Are there any new tutorials of doing so? thanks
Thanks for all your answers .... I will stick with my old DXF implementation, since this is personal project.
回答1:
I think your only choice if you want DWG is to use OpenDesign. If you don't want to pay what that costs, you can write DXF instead. I have used VectorDraw, which does give a reasonable object model, and can export DXF without any extra component (I think), or use OpenDesign to write DWG.

Here you have exacly how to do it. AutoCad includes an API for doing that. The problem is that you need to have AutoCad in the computer where your application remains.

Autodesk sell a library called RealDWG which allow you to read and write dwg file with C# without AutoCAD installed. ~ 2500 € / year.

You can also use DXF, which is easier to read and write (text file). The reference can be found here : http://usa.autodesk.com/adsk/servlet/item?siteID=123112&id=12272454&linkID=10809853

As mentioned by others, OpenDesign is one possibility. It is, however, prohibitively expensive for small companies; we have started using CadLib, which is far cheaper and seems to do the trick so far. It writes to DXF or DWG, and has fairly good documentation.
回答5:
If you're planning to create the file without having autocad running, then you CANNOT use the .net API. The use of the .net API basically requires AutoCAD (or the CoreConsole) to be running for it to work. (You can open other databases but you'd be doing it in process from Autocad.
If you don't want it running in process you can use the Interop API.
Or the other alternative is to is to write to a DXF format which can then be imported into AutoCAD (or any other CAD program) which is capable of reading the format.
