What to expect from your conversion
While conversions for different CAD-based applications will yield different results, most will have the following limitations:
You may need to create your own materials.
UV-information may not be preserved which can prevent provided textures from being re-applied.
Geometry may be fused into a single object.
Geometry may be faceted.
Layer information will not convert.
Objects/features generated from plug-ins may not convert.
