A real quick topic but something I’ve been meaning to post for ages. Many of you may already be using the character map but for those that are not here is a tip for adding special symbols such as Degrees, square etc.
Click the start button and type CHARMAP, select the symbol you want to use and then copy to the clip board, you can then paste this into text etc.
Another option is to use the keystroke to directly insert this into Revit. If you look in the bottom right hand corner of the Character Map you will see a keystroke combination. The example on the top image is the degree symbol. The keystroke would be ALT+0176 so you hold the ALT key down and type 0176 (you need to use the number pad for this) and the symbol is inserted into Revit.
