Change Grid Size?

[davecollinsjr]

Hello,
I love wings3d and I'm using it for 3D printing. I'm a total noob - thank heavens for the tutorials!!

I thought it might be useful for me to think of a wu (wings unit) as 1mm in size (I realize it is a theoretical unit - but I thought it would make my design tasks easier). However, if I do that, the size of my model is such (40mm x 70mm) that the tiny 10x10 grid becomes useless.

Is there any way to change the grid size so that it is, perhaps 100x100 instead of 10x10?

Thanks!
Dave
