Let's have a break for a while then, I'll try to reproduce those files by myself then I'll post them again using the method A-DRAW-PER FILE, moreover if it's me the author I can give the licence that you need!
Just let me know, unfortunately I have a lot of free time in these days.
@everyone that can cooperate
I can provide architectural blocks, but it would also good if someone that can draw mechanical parts would do the same thing in that sector. I don't know very well, but an example is given by the LC block list once the program is installed: you can find a screw, so mechanical designers could add more parts, I am not able to create them because I came from another sector
Best regards to everyone
...the problem is not the problem, the problem is your aptitude about the problem...
