I am sketching house floor plans. In the Diagram Format Panel there is a point size adjustment next to the grid setting, but it does not seem to do anything. Any tips?
In the options panel on the right side un-check the guide box. Then set your grid settings to your required size.
Any shape you add will start of as its normal size. When you re-size it it will conform to the grid settings. Also, moving a shape will conform to grid settings.
