Units

I've used AuotCAD LT for years but only as an amatuer to help build an
occasional piece of furniture. How do you set the units to be used on the
2004 version? I have the size and shape of my lot on AutoCAD but it has
dimensioned it in inches and I can't seem to change it. I guess that I have
the same question if I want to use millimeters (as my primary unit) to
dimension a piece of furniture. I apologize if I'm in the wrong group.

 

If I type "units" I get a box with the heading "Drawing Units". The
subheadings within the box are "Length", "Angle" and "Drag and drop Scale".
I don't see any Insertion Scale. I very seldom need units in anything but
inches but I remember being able to change versions previous to 2004. Can
you please help me further?

 

I set the "drag & drop" to mm but nothing happened. This is frustrating
because I could readily change units on revisions prior to 2004. I
occasionally want to use millimeters because they are easier to work with in
some cases. I only use the program in my hobby of wood working so I can
live without it. Thanks.

 

Try setting LUNITS to 2, and LUPREC to 0.

In AutoCad pre2006, units is units is units. It takes no account of the
type of units when inserting blocks, Xrefs, etc. eg, if you draw a
table in inches and a chair in mm, insert the chair into the table
drawing, the chair will be 25.4X the size it ought to be.

You will have to set the insertion scale on import of the blocks.

Similarly, if you want to dimension something up in mm and you have
drawn it in inches, you will have to scale up the drawing.

 

Thanks for all of your suggestions. No more than I use AutoCAD LT 2004 I'll
just continue to muddle along experimenting occasionally. I seem to
remember that in previous versions I did not have this problem but that was
a long time ago.

 

I used fastcad for years, it was simple in practice to change units you
just went to units command and switch to mm and everything was
instantly rescaled to mm, switching back was the same.

In autocad it's different, there really are no units except machine
units. You then choose what you want to call those machine units ie.
inches, mm, feet, etc. So to switch units in Autocad you must rescale
your machine units to what you desire. For example if you're calling
1 machine unit 1 inch then to switch to mm you must rescale/multiply
everything by 25.4 so that you now of 25.4 machine units where there
used to be 1. I don't like it because in rescaling everything you have
to unlock all layers.
