Snap ?

Hello.

Normally you click twice to create a line.

Now I have the issue that when I click once, and then enter an number for the length, it wont snap onto the nearest line, while the green "nearest" symbol shows up.

It snaps onto the 91 degrees angle as shown in the pictures, and I want to snap it along the blue line (90 degrees).

I tried to find something to solve this issue but I couldnt find anything.

Please help.

Thanks in advance.
