You can start by placing a guide point at x=5 and y=5 by starting from the origin and typing <5,5,0>. You could also just move the object to that point by typing [5,5,0] after starting the move.

<x,y,z> gives you relative coordinates, [x,y,z] gives you absolute coordinates.

If you really have to have a grid you could model one easily enough (The Sandbox tools would make quick work of it) or you could use an extension to create a grid of guides.

I rarely find coordinates useful in my modeling but it is handy to know.

The most common application I have is when I’m fixing a model for someone else and they’ve got their model at a great distance from the origin. I can grab the object and start moving it, then type [0,0,0 and move it to the origin instead of dragging it.

Coordinates: The Measurements box accepts global or relative coordinates. To enter global coordinates, use square brackets, such as [3’, 4’, 5’] to designate coordinates from the model origin. To set relative coordinates (from the starting point of the move operation), use angle brackets, such as <3’, 4’, 5’>.

Thanks for your reply. I see where you can type in Measurements in the bottom right corner, but don’t see anything that lets me enter coordinates as <5,5,0> or [5,5,0].

No. You can’t enter coordinates to start drawing an edge. As I told you, start by placing a guidepoint relative to the origin. Then you can start drawing the edge from there.

Here I’ve placed a guidepoint at (5,5,0) and then I’ve drawn an edge starting at that guidepoint.

I’ve told you several times, you cannot just start drawing an edge by entering coordinates. Place a guidepoint at the desired starting point and start drawing the edge from there.
