I noticed that I raise a dwg in which there are proxies ...with autocad mech tells me that there are and if I want to hide them etc but in draftsight just doesn't communicate anything like ever?
I repeat it, and try to read the phrase well, are few words and the concept is quite easy.
open the drafsight guide (believe it exists, it is not a legend) and write proxy. you will appear 4/5 results. make the effort to read them.
If you do not even know that new programs you use (solidworks, mechanical, drafsigh) there is a guide the problem is not programs, it is yours and it is big.
a drafsight open f1 prizes or open the menu with the question and click on guide or help
