Convert CAx data to symbols elmt

Welcome.

I work on Siemens components and I try download CAx data files from Siemens site and import data (dxf and csv).

But it's not possible.

On Siemens CAx portal aviliable many formats to electrical software.

I try import some files but not correct results.

Someone on community try make import from Siemens CAx site to elm? 

CAx formats and a plan macros it's on many sites but would be perfect to import to Qelectrotech. Of course I know it's not simple.

And I have second question : someone have information maybe some databases symbols example from see electrical or others are compatibille to import to elmt?

Best regards and sorry for my English.
