Hi Marek,

re:

The relative point input needs a point coordinate, either an x,y value (which will use z=0) or an x,y,z value.

Also if your locale's number system uses the comma as the decimal separator then put it in as a space between the x and y coordinates instead of a comma between them.

So either r-5,0 or r-5 0 if you use commas as decimal separators.
