map 2000 transform of coordinates

Hi
If this isn't the right ng, I appologise...
Is there a step-by-step resource on how to convert drawing in UTMs to State
Planes coordinates? I find the Acad Map 2000, Release 4 User's Guide
confusing...and my two big reference books, Osborne's Complete Reference to
AutoCAD 2000, and Sybex's Mastering AutoCAD 2000 appear silent on this
issues. It appears that to do the job in Acad Map, one has to attach
drawings that have defined or assigned coordinate systems... and using an
alien concept to me...drawing sets, ACAD is supposed to do all of the magic
adjustment. I've tried to blunder my way through with no luck. My current
solution right now, is to do coordinate conversions outside of Acad using a
DOS program called Trallaine which converts Acad12 dxfs from one coordinate
to another. This appears to work but Acad's solution must be more
elloquent...if I only knew the magic series of commands.

Is there a step-by-step resource on how to convert drawing in UTMs to

Open your UTM drawing.

In the Map pull down menu, choose Tools>Assign Global Coordinate System... and check the correct UTM coordinate system is assigned.

I would also check that UNITS is set correctly.

Save and close.

Create a new blank drawing and, as above, assign the correct state planes system. (again, I'd also set UNITS correctly too - it can save hassles and weird behaviour in the future).

Under the Map menu, turn on Utilities>Project Workspace.

Open a Windows Explorer window and drag your UTM drawing into an empty area of the Project Workspace (if you have alias problems, the manual is pretty easy to follow on how to set one up) - Your UTM "Source drawing" is now attached to your state plane "Project".

Double click on Current Query in the Project Workspace.

Press Clear Query if there is anything in the white current query area.

Press Location and choose Boundary Type All.

Set Mode to Draw.

Make sure the tick box under Options, next to Alter Properties, is empty.

Execute the Query (don't just press OK).

That should do it. As usual with AutoCAD based stuff, there are several ways to access each of the steps - hopefully this will get you started, and the manual will begin to make more sense.

Thank you so much. Works like a charm. Too bad you weren't asked to write
the AutoCAD Map User's Guide.
BTW, can I change the format of the x,y position readout at the lower corner
of my Win2000. x is shown as 1.3447E+07 feet and GPS readout for the guy's
on the ground are obviously down to the decimal, i.e. 13447235.36

No bother.

Reduce the precision under UNITS. It only affects display precision, so don't worry about it reducing accuracy.

A warning about UNITS: if you set angles to be measured clockwise from north, as makes sense, you may find object tracking is messed up.

Also, a tip about Map 2000 on Win2000 - I don't think it is a supported platform. I remember having a few irritating issues, but mainly I found performance gradually reduced as the day went on. Rebooting windows at lunchtime usually kept it acceptable.
