Help drawing 16mm lines.

I need a bit of help with doors in doombuilder.

When drawing doors, the small sector in between is made of two 16mm (or however long) lines. Can someone tell me how to draw those 16mm lines?

Cheers.

You'll need to make the grid smaller: by default, it snaps to 32 fracunits. Click the 'grid' section of the status bar at the bottom of the window. Or just turn off snapping.

the [ and ] buttons on your keyboard by default change the size of the grid as well.

Okay. Thank You.
