Good afternoon. We wanted to purchase this software but encountered a problem with training. If possible, please help with a mentor, preferably in Russian.
Hello @Константин 
,
I’ll respond in English, hopefully that’s okay with you.
We generally offer various training materials, though unfortunately, they are mostly available in German or English, but not in Russian.
You can find many free webinars on our website here:

Additionally, we offer individual training (available in English or German). For more information, please reach out to our sales team via this link:

Best regards,
Fabian
