1) Following message appears during the importing process:
In your DWG file are one or more .SHX files which were created as external references during the last saving of your DWG file. This application of the external references must be avoided, because our evo software can't handle the references.
You can try to include these references as blocks in a CAD software and/or clean the drawing.
It is also possible to download and install the free CAD software DraftSight 2016 (http://www.chip.de/downloads/DraftSight-64-Bit_64883837.html).
Once you load the DWG drawing in DraftSight, you must open the context menu by right-clicking on the unresolved reference in the References tab. There you will find an entry in the menu "Detach". If you execute this command, the external reference is removed and the DWG file should now be imported into our evo software without any problems.
2) Open the problematic DWG file in a CAD software and execute the "Explode" function several times. After this save the DWG as a 2010 AutoCAD version, and then import it again into evo. In the corresponding screenshots the free CAD software DraftSight 2016 is used.
