North rotation

[Anonymous]

How does one do a North rotation in Civil 3D?
What if your drawing has points?

You need to rotate everything so that North is North. If you don't have to
alter the original drawing. Insert it as an Xref and rotate the Xref. I
don't know how a North Rotation affects Points. But I'd assume you'd have to
export the points from LDT and import them to C3D.

Of course you will either want to start your new work in the correct
coordinate system or rotate all the work into that system once it is
established.

One thing you could try. In LDT establish a UCS that is equivalent to you
North Rotation and WBlock out the entire drawing. Then import the results in
to C3D

When we've started new drawings, the object is to get the topo to our
engineers as quick as we can so they can begin design. We only use
"assumed" bearings at the start of a job. Our drawing is set up from the
beginning to fit a sheet in model space. We will then go back and tie our
job into USGS coordinates. We would then change the north of the drawing to
relate to our monument tie-in. When these drawings are then converted to
c3d, that orientation is being lost. I just found this out when I started
using a design drawing done by our engineering staff. Until everything is
being done in c3d, is there a way to work around this problem?

It is my understanding that users of Field Book may not be able to do this
but I don't use the Field Book. I make sure that "Allow Points to be Moved"
is turned on and I just move the whole drawing to a point that represents my
State Plane, then I rotate to my State Plane "UP" North.
AUDITING & SAVING, prepared for the worse and normally I get it done without
too much fanfare.

I think my advice would be to finish those projects in Land Desktop, if
that's what you were using, and start new projects with Civil 3D.
Convertting LDT projects into Civil 3D can be problematic, especially when
the project is well under way.

I'm new to 2008 and I'm having a tough time of it. I get the fact that 2008
has North UP in all cases and I'll deal with that but I'm coming from the
survey end of this and don't understand this program well. In 2004, drawing
north was adjusted to fit our paper the best. We are converting over now
but many of our drawings are still 2004. When these drawings are used as
base maps for design, they no longer carry over the same bearing system in
2008. How can I change the orientation in 2008 to match what has been done
already? Do we have to rotate each drawing as soon as it is created in 2008
to match our "old" bearing system? We currently do a "save as" and change
the name but in 2008 then, north is "up". This is a big issue for us and I
could really use some advice.
