I imported a .dxf model in MED via Import FBX,dxf.... While the mesh is imported correctly and can be textured, the engine preview does not show the model, but a black screen only.
After saving the model as a MDL7 file and reloading, the model can be displayed correctly in the engine preview.

Well, just a minor flaw, but people should know about it.

GSTUDIO A8, Extra edition, MED version 6.922
DXF file was created by Blobsculptor for DOS running in DOSBOX on WinXP SP3. Geforce 6200 512 MB, driver 6.14.0012.8558 from 8.10.2011.

Thanks for the info. Dxf is a mesh only format, which probably causes an issue with the preview.

OK, a simple solution for engine preview probs whatsoever.

A model created in MED and skinned in MED is shown in engine preview correctly.
However if you have an imported model from other (various) formats and the model is not shown correctly in engine preview , especially a DXF imported model, after skinning save it to MD5 or MD7 format and reload it.
Note that you need to skin your model correctly and have the settings of the skin correctly also to avoid any problems.
