It all depends on the Import function available in the Markierteufel Pro . I visited the official website, and although their product is present, no downloads are available, or anything I could use to provide the necessary details.
Firstly, check the files Markierteufel Pro supports, then export the graphic from the DWG to one of those formats if you have the possibility.
Additionally, get in touch with the developers using the contact details on their official website.
