Hello, I've got a very strange problem on my Archicad 15 x64. When I start to use the dimension tool, I put the firs point, then put the second one, and when I make a double click ot stretch the dimension line, nothing happens! When I click 3 times , the dimension line is stretched but the program puts a third point between the other two, and make the dimension on two parts. That's very annoying! Please, help!
