JMT - Import dwg

When importing a dwg (I have tried v2000 and v2010) into JMT(android), the arc linework does not show. Is there a specific dwg version that is required for JMT?

I have yet to find a way to import arcs, particularly from CAD files.

From DWG/DXF files, regardless of version, arc entities aren't imported at all, while arc segments of polylines are imported as a chord line.

Other file formats such as SHP and KML import arcs as tessellated line segments. I can bring an arc in, but it becomes ~100 line segments (depending on radius and length).

Here are some test drawings that I experienced this issue with. Each contains the same three entities: 1 line, 1 arc, and 1 polyline which includes an arc segment.

For me, this happens with any version DWG/DXF, so I've attached just a few examples in the Zip file.

For reference, the coordinate system is NAD83(2011) Alaska State Plane Zone 8, US Survey Feet

Import points and dwg. Looking at the map they both line up. When you do a localization, it looks like the points get shifted but not the dwg.
