AutoCAD DWF File Format

Post by fchateau » 28 Dec 2005, 00:39

I originally posted a message asking if you had considered working with DWF files. I was wondering if there is a reason why DXF files are better. Afterward I managed to locate the DXF file format specification on the AutoDesk Website. It's definitely more comprehensive than DWF format.

My only concern was that DXF files are large and might be slower to load and transport but I notice there is a specification for binary DXF files. That would seem to resolve the problem.

Can CADImport.NET read binary DFX files? If not, is the difference between binary and ASCII format very noticeable?

Regards,

Fred Chateau

Dear Mr. Fred Chateau,

Yes, really binary DXF file format borrows on the average on 25 % less size (as official AutoDesk(R) information says). Our customers ordinarily use DXF ASCII. For decreasing of the file size DWG file format is usually used.
We plan to release support of the DWG file format in DXFImport .NET up to the end of the February, 2006.

DXF BINARY and DWF are also in our task list.

Sergey.

Are you able to write managed classes to import the DWG file or do you have to write a custom managed wrapper around unmanaged code? My project manager does not want to use any managed wrappers in our applications unless they are written by Microsoft or AutoDesk.

Hello,

Yes, we will write our own library for opening DWG that will not use libraries of other companies.
Perhapse there will be a restriction on the supported DWG formats. Access interface to the entities will be the same as the access interface to the entities in DXF files.
