I use it after switching from ecscad (aka Aero II and III).
It was my employer's choice to run ecscad for few years and ±2 years ago to change to Electrical. It made me happier - I did not like that program for various reasons, one of them was how "somebody" set it up (for example directory structure went over the limit of maximum number of characters!).
I need to learn a lot (at my age...), but ... I am coping so far.
[My apologies to anybody who likes ecscad, but it is as it is. I don't want to offend anybody].
Regards,
Andrzej
