Hi There,

Do you have any update on the issue, I too facing the same challenges.

@rahulpd,
Hi.
The issue is not resolved yet, unfortunately. It is helpful for us if you can submit your example file for the investigation, so we can inspect and check it.

@Buffer2018,
Hi.
We made some changes so the result is not empty now but linearized (and some other issues may appear too) as a intermediate solution. The reason for the issue is that original file has 2007 DWG file format, that significantly differs from other versions. We work now to implement full support for 2013 and 2018 formats, after that we plan to work on 2007. Please use more recent DWG formats if possible. We are sorry for the inconvenience.
