    When your cursor is not near an ortho angle, the line is "free" to be the angle you are indicating.
    I've given that a shot in the past and have had a hard time getting used to it. It somehow feels less solid to me. I keep fearing that the lines I draw will be at 1 degree when I actually want it set at 1 degree. I don't know. Maybe it's just me being a crumudgeon ...

    And why the limit is 32,767!

    Useful command of ConvertPStyles for when you get a drawing from someone who uses name dependent plot styles as opposed to color dependent. And vice versa.

    I can't believe you had 32,767 layers in a drawing!

    Didn't happen.
    Had to know the upper limit.
    Greatest number approx. 1200.
    Too many people didn't purge unused layers in too many xrefs.

    8 x 2 = 16
    16 x 2 = 32
    32 x 2 = 64
    64 x 2 = 128
    128 x 2 = 256
    256 x 2 = 512

    Those numbers look familiar? If you keep going with x2, you'll eventually get to 32,768 (zero is included as a number so it's 32,767).

    They probably made it that big because, hey, you hit 1,200, right? AutoCAD put it a few levels above what they thought would be the most any average firm would get to just to be safe. But I'm SURE someone has hit the limit anyway.

    Actually, it just doesn't sort them at all. It displays them in the order created (which is how they are stored internally)

    Because back in the day of 386's, etc. you might not want to wait on AutoCAD to sort a large number of layers.

    It's not. I think r14 was the last release with that limit.

    I just created 35000 in a drawing (using r2006)

    Use this code if you want to try for yourself

    Code:
    (setq i 1)
    (command "._layer")
    (repeat 35000
      (command "_m" (itoa i))
      (setq i (1+ i))
    )

    ohh I believe it, I deal with alot of very old legacy drawings that have been floating around for years....you have no idea how happy I was when Acad enhanced the purge command to automatically purge nested items and purge w/o confirming.
    That and a lisp routine called shortsym are my friends. I'm also very happy that the layer command will now delete the layer filters for you if they exceed the actual number of layers in dwg. I have a legacy drawing in front of me now that has 100 layers and about 2000 filters (most of them empty). thanks for the info-

    Hi folks.
    Good thread going here!
    Anybody know how I can get my osnap menu back when I press shift+right-click?
    Also, why double clicking on text doesn't do anything? I have already checked dblclickedit variable.

    Thanks!

    Marv
