Hi Michael,
I just removed my porting to UWP, as already say is not my intention destroy your great work.

"That works ok for software that's at a very low price and high volume, or that is free with "in app" purchases. MoI is not in that category at all, it's totally the reverse of that, it's a lower volume and somewhat higher cost software and used to get work done."
Thank you, I understand!
...now wich I'm speaking directly with you, I have a question: why there aren't measuring tools(distence, area and volume) to use during drawing steps? For me this lack is a great problem...
