I have noticed in certain cad appz that no matter if you resize the window the actual drawing keeps it’s size and dimension’s how do I recreate this?
Thanx in Advance

simple… if the windows is 500 pixels wide and 100 pixels tall map it to -250,250 -50,50 instead of using your older ratio…
key idea is that keep the ratio of the window and the ratio of the co ordinates you are mapping to same…
