@78783718,
Hi.
Here are some notes about first problem. Unfortunately, we don’t have support to change format for DWG yet. We can write the file with the version in which it was created (DWG 2013 and DWG 2018 only now). It is not enough to use DwgVersionWriter to change file versions, we will remove it in further Aspose.CAD versions.
