The dimensions of free bites is for technical drawing DIN 509 standardized. When one dimension is different then the Clear stitch forms E, F, G and H. The different forms are free stab in the table below precisely defined. Whether it is an external (eg a wave) or internal (eg a hub) in paragraph applies does not matter.

If you have a free sample draws, you can either completely or simplified sign to show. In the simplified representation must, however, the form, radius and the depth of the relief (with a reference arrow) indicate. This information may e.g. as follows: DIN 509-E1x0, 2
The indication from the example indicates that the Clear Stich (DIN 509) form the 'E' has a radius of 1mm and a depth of 0.2 mm.
