1st off, i'll say that i'm new to AutoCad.
My question is: Why certin AutoCad files, I'm not able to draw lines?
I'm in model space. I can move objects. I can even erase/delete things. But I'm tring to edit this shop drawing, i need to add some details, so i need to draw some lines. I use the "l" command. Select my 1st point, then 2nd point. It doesn't work??? The Command line keeps saying: Specify next point or [Close/Undo]. But no lines are getting drawn. i finally have to hit escape to end the line command but no lines have gotten drawn. its the same thing if i draw a square or circle. (Not sure if you need to know this but these are my companies files created by a former employee of my company using our own AutoCad. So, i would think if he's locked this file somehow, i should be able to unlock it.)
