Once again this is a textbook example of someone screwing up a drawing
because they don't take a minimal amout of time to figure out how to
use the software correctly. The simple fix is isolate all the tick
marks, erase them. Then open the dimension style dialog box and fix
the dimension style you are using to use the arrow, tick mark, etc. of
your choice. Then when you freeze, turn off the dimension layer all
the dimension objects disappear.
So, if you freeze the dims layer - as opposed to turning it off - I
guess they disappear, right?
Now that you mention it - YES, when I freeze them they disappear, but when I
turn them off they remain... whats the difference?
This isn't well documented but you can easily test this for yourself.
Just make a simple block comprising objects created on Layer0,
Defpoints and 1 or 2 other layers. Now insert the block onto each of
the layers and play around with the layer settings.
You will see that turning off a layer only affects the block objects
of a block inserted on that layer if those objects belong either to
that layer or to layer0.
Freezing a layer 'freezes' any blocks inserted on that layer and any
and all objects within those blocks.
Note also that with 3d objects, turning off a layer renders 3d objects
belonging to it invisible, however they will still be seen to
'obscure' other objects behind them. This is true whether or not the
objects belong to a block.
What strawberry said. Also, note that when layers are frozen they are
completely non-selectable. But when they are merely turned off, they
are selectable with the "_all" selection option. There are handy
reasons, I suppose, to turning off a layer, but in my practice, I find
it a whole lot safer to freeze layers rather than to turn them off. I
just don't like suprises in my work.
