Q: I need to place a corner sink cabinet at a 45 degree angle. Is there a simple way to do this?
A: Yes, Solid has a Hot Key for this.
1) Start a new job. Go to the Solid Button \ Preferences. Now go to the Tools tab and notice the Snapping Options \ Corner. It should by default be showing the letter C. Just click OK to continue.
2) Place two Walls at a 90 degree angle. Drag a Base cabinet into the corner area but do not click with the mouse to drop it in.
3) Now simply click the letter C on your keyboard. This will place the base cabinet into the corner at a 45 degree angle.
4) Now place a base cabinet on either side of the corner cabinet to prove that it is positioned correctly.
