Can you change the Drawing Origin (0,0) location?

N/A
I'm starting to use Solid Edge 2D and I like it a lot so far. However, I
need to be able to export 2D designs in .dxf format to read into the Rhino
program.
To have them read into Rhino easily I need to be able to set the (0,0)
origin point on the drawings.
Currently the (0,0) origin is always at the lower left hand corner of the
drawing sheet, but this is clumsy as I can't have any dimensions or text on
the left or bottom of my drawing.
Is there a way to change the location of the (0,0) point on a drawing sheet?
Thanks,
Paul T.

Paul,
No the origin cannot be moved. However you can move your geometry anywhere
in 2D space. The geometry does not have to reside within the bounds of the
displayed sheet. You commented that you can't have any dimensions or text
the left or bottom of the drawing. You can draw geometry outside the bounds
of the sheet. I don't know what you are trying to accomplish. If all you
need to translate is the geometry and not the sheet border, you may find it
better to work in 2D Model instead of on a working sheet (Sheet1). There is
no sheet border in 2D Model.

Its pretty simple, I'd like to be able to have a drawing that's reasonably
centered on the drawing page while also having a 0,0 origin at a location
that you can place on a chosen point on the drawing. For example if the
drawing is a fixture plate, I'd like to be able to make the lower left
corner of the fixture plate be at 0,0 without having to jam the fixture
plate design down on the lower left corner of the page.
This is an issue as I will be exporting the 2D drawings using .dfx format
into other CAD/CAM programs for further design or machining. Right now when
imported the drawings come in with a somewhat arbirtrarily placed origin
that will offset the designs by that arbitrary number. For example I often
will need to read them into RhinoCAM for further design work, and instead of
coming in with correct alignment with Rhino's axis they will come in offset
from the Rhino axis by the arbitrary amount, and having to align them
everytime would be a hassle. I also use the SheetCAM package alot and have
the exact same issue when importing designs into that package.
As you mentioned, with a working sheet I can workaround this issue by
temporarily moving the entire design so that the desired 0,0 corner of my
design is at the corner of the page before doing the export and then moving
it back for printing and further work on the design. A hassle but it works.
I'm still playing with the 2D Model page but I don't see any way to even
move a desired design point to the 0,0 location in this page, when you do a
move it doesn't show you any absolute locations, but if you know how to do
this please let me know.
The inability to easily specify a desired 0,0 design origin is a surprising
limitation in this otherwise powerful package, I guess I might be able to
use the workaround before exporting but I do that alot and it would be a
pretty big hassle.
Thanks for your help-

I figured how to do what I need to do in the 2D model view, if you turn the
Grids on it displays the 0,0 point as the intersection of 2 red lines, and
its pretty easy to move a desired design point to this location, and then my
exports work correctly.
Its a slight tradeoff since the printing behaves a little differently from
the 2D model view, but I can live with that.

To identify the origin of the 2D model sheet turn on the grid. You can also
place a point and type in 0 values for the X & Y location. I don't think
the point tool is available by default. You may have to turn it on via
View-Toolbars-Toolbars-Customize

Re: Can you change the Drawing Origin (0,0) location?

Paul,
I was guessing that you were sending the geometry to a CAM package. Ad David
suggests in a responce further down in this thread, you can place a point at
(0,0). The Point command is in the drop list beside the Line command. Place
the point on a layer that can be turned off. Also you can use the properties
of the point to make it thicker or change the color so it is more visible.
Another thing to consider is to place a lock constraint on the point. This
way you don't change the location of the point by mistake while modifying
other geometry. This works well with drag modify. The point will not change
location.
To easily move all the geometry in relationship with the point, use Ctrl+A
to select all the geometry. All the geometry will highlight. Use Ctrl+click
on the point to deselect it, take it out of the select set. Now you have all
the geometry except for the point in the select set. You are going to use
the move command to move the geometry. The Move command will suspend
constraints during the move and will override the lock constraint on the
point. That is why you take the point out of the select set.
Now with the geometry to move selected, click on the Move command. Click on
the from point, for example the corner of two connecting lines that you want
to be at zero. You will see the endpoint indicator when you are over an end
point. Click on the endpoint. The selected geometry will now connect to the
cursor. Click on the point that is at zero. It will move all your geometry
and put the initial point selected at the zero point.
Give this a try with a simple rectangle. Use the bottom left corner of a
rectangle to position it relative to a point. Then move the rectangle again
using a different corner of the rectangle to position the rectangle relative
to the point.

Rick and David, thanks for your help, now that I've got a better
understanding of the different views and commands I'm in good shape.
The work flow will be to do my designs in the 2D Model page, which makes it
easy to place the 0,0 origin where I want it, just turn on the grids and do
a "Move All" to place my desired design point at 0,0. Exporting from the 2D
model page will now bring the designs into my CAM programs in sync with
their axis grids.
Then for printing to scale and centered on the page I'll use the "Place 2D
Model View" (sorry, probably not the exact right name) to place a view in a
design sheet, and use that sheet for printing.
A very nice package and their "hook 'em on the free one" plan will probably
work in my case, at some point when I need detailed 3D design I'll probably
pop for the full 3D version of Solid Edge.
Thanks again for your help,
Paul T.
