Hi there,

While drawing a line, I know I can type in the degree to constrain its direction.
To do that, I type in the degree value in the numeric field, though I wonder if there's a shortcut for that, so I can decide the degree without moving the mouse cursor from the viewport.

Hi verysame, yes if you want to set angle constraint to say 30 degrees, you can type in:

<30

and push Enter. When you type you'll see your keystrokes go into the x/y/z coordinate box in the bottom toolbar, you don't need to click on it first. If you type a single number in that box it will be the same as if you clicked on the distance constraint box and put in a number and if you use the "<" character in front of a number that will be the same as if you clicked in the angle constraint box and put in a number there.

See here for the different kinds of input you can use in the x/y/z coordinate input:

You can also press the Tab key to cycle keyboard focus between the x/y/z input, distance constraint input and angle constraint input.

Perfect, that's what I was looking for!

Thanks Michael.
