Known Issues:

Limitation: The default layer in Alias is called DefaultLayer and cannot be deleted or renamed.
Work Around: The translator will rename the layer to "_Default_" so that round trip transfers don't end up with multiple layers called "DefaultLayers".

Limitation: Some trimmed periodic/closed surfaces may not get trimmed properly.Work Around: Please detach such surfaces into two before transfer or convert them to shells, using SurfaceEdit->Stitch function.

Limitation: Some complex multi-level instances may not transfer properlyWork Around: Please extract the instances using Edit > Expand Instance before the transfer.
