Autocad 2006
I am mot very conversant with cad,all i use it for is to pick out co-ords
for setting out purposes.
I have one large layout drawing which shows the external brickwork corners
of a pack of twelve units,the values are stated on the drawing and cad also
reports the same values.
I have seperate drawings for each of the twelve units,detailing
foundations/internal brickwork etc from which i would like to aquire the
detailed setting out coords.The values produced are wildly different---i am
assuming it is a generic layout to which the XYZ origin has been incorrectly
set.
As i have the values of the corners,how do i reset the origin so cad will
produce the correct values.
I have gone thru the help files and that has left me more confused than
ever.
Is there a simple way to generate the info i need?
Thanks in advance folks

Moving the origin would be an option (type UCS MOVE then the co-ordinates of
where the origin should be).
But I'd normally move the drawing back to the correct location. The easiest
way is probably to xref a correct drawing into the incorrect one, then move
the objects to the correct location, using the xref as a reference.

Thanks for the help--i think the xref thing is way beyond my cad
knowledge,but re assigning the origin looks like an achievable option with
the knowledge i have (must go on a cad course) --the relavant buildings are
not square to the grid (O/S)
As i know the coord values of the brickwork on all corners how do i go about
defining where the origin is?
Is it as simple as setting the origin to a corner of the building and
telling cad the angle from north the y values lay?

thanks for the help

First thing to check: do any of the drawings have a custom UCS (co-ordinate
system) selected? Type UCS then return twice to switch back to the default
(World) co-ordinate system. Hopefully this should cure the problem. If not
I'd be tempted to tell the person who gave you the drawings to sort them
out - there's no excuse for drawings that don't "stack up" properly. And
that way it's not your fault if something ends up in the wrong place!

But if you do have to sort it out yourself, there are various options in the
UCS command that could help you. It's probably worth looking it up in the
help file.
For example, typing UCS Z 10 will rotate the co-ordinate system 10 degrees
anticlockwise. Or you could use the 3 point option, where you pick an origin
point, a point to specify the rotation of the x-axis and a point to specify
which side the positive y-axis is (but that can give unexpected results if
your points aren't in a flat plane, which happens quite a lot).

Good luck!
