I am so happy! SOLIDWORKS R&D listened to us!
Thank you, Matthew Lorono!
Looks like in SW2020 Detached functionality is merged in the standard drawings!!!
Finally we have a drawing environment that is responsive to detailers.
One more note: if you will benefit from this huge enhancement, send a thank you note to our forum colleague, Grant Mattis.
Long story, short, everything started with Grant.
Also, many thanks to Solidworks Swcare, Mark Johnson for being the first to listen to Grant and for bringing in the cavalry.
