And one more question - the new beta grouped all objects with the same name. Could it be possible to get an option at the Import/Export options for it like "group objects with same name" because it can cause problems?

For example - I get a Rhino file there is an object with a name that is copied several times - for example a bolt with the name "bolt 30x10". After meshing per MoI and import the mesh to Rhino all bolts are joined to one mesh. Now only ungroup and explode helps to get single objects - no, not single object, all mesh faces are splited. So, the new feature can cause a lot trouble.

If you dont like to add an option for keeping separate objects separate, please add an ini file option for disabling it.
