WF3, part in mm. I created 4 datum points on the front plane: (0,0), (30,0), (30,6), (0,6) -these point are at the corners of a rectangle. I then wanted to create a datum curve using "Thru Points" with connect type "Single Rad". I started to add points 1, 2, 3. At this stage it asks for a bend radius and I enter 2. It won't accept the value and insists that "Range is 4.1500 to 5.9999. Please re-enter:" My question is why it won't accept 2 mm and how do I change the range? I need to use 2 mm as the bend radius. How do I solve the problem? I would appreciate any help. Thanks,
