Clearances

The clearances between the segments of the cutout and the line segments of the profile section are numbered like the radii, if not otherwise specified according to the figure below.

Figure 2:2. Clearances for different profile types.

Certain clearances may be irrelevant for certain cutout types, for example, C3 for flat bars, bulbs and L-bars when the cutout is quite open on the mould line side.
