Origin and Element Placement

N/A
Hi
I started a new drawing, changed the origin and then drew a vertical
line with the lower end located at the new origin. But now when I look
at the properties of the line it says the end point is at -9 ft 0 1/16
in, 0 ft 3 15/16 in. Does anybody have any idea why it is not 0,0?
TIA

FWIW I just changed my account settings to something more friendly :-)

Phil,
When you say you changed the origin, I assume you are talking about the grid
origin.
You cannot change the actual model origin.
The grid origin can be change so that you can use the grid points/lines with
respect to a defined point.
This will not redefine the objects relative to the grid origin.

Oh. I'm not an expert but I think you can change the actual drawing
origin in AutoCAD (haven't used it for a couple of years) so I assumed
that was what I was doing. I would change it to the bottom left corner
of whatever I was drawing and then I wouldn't need to do so much math
trying to place things. (I know there are more advanced ways of doing
that but I never learned them.)
Thanks

Phil,
Have you worked through the tutorials?
If you are trying to draw geometry to specific coordinates,
you are not using the built in tools effectively.
Solid Edge and Solid Edge 2D Drafting are fully associative systems.
What that means is that geometry is not simply stick figures.
I do not draw precise geometry.
I draw the basic shape and with the geometry constrained as needed,
then I place dimensions and drive the geometry where I need it to be.
For example, I need to create a 2 in. X 4 in. rectangle.
Make sure Maintain relationships and Relationship Handles are enabled.
I draw a rectangle. It doesn't matter the shape.
I place a linear dimension for both the width and the height.
I change the value of the dimensions to 2 in. and 4 in.
I now have a rectangle the correct size.
The best part about this is that I can easily change the size by changing
the dimensions,
not by moving the lines of the rectangle.
You were talking about having to do the math. Don't worry with the math.
Let the system do the math.
Just draw what you want and let the system drive it where you need it.
Regards,
Rick B.

Never thought of that. I did the tutorials but they pack a lot in and it
didn't click that that was so important to using the program. It just
seemed like a handy feature to look into later. Thanks.
