Part Geometry and Connection Angles

Whenever an edge is connected in a fillet connection to a plate surface, the nominal geometry of the part may have to be re-calculated depending on the bevel type, the material thickness and orientation and the connection angle.

This is illustrated in the figures below. For this facility to function it is essential that the bounding curves have been intersected in the mould plane of the current panel.

Figure 1:25. Change of nominal part contour.

In the figures the mould plane has been indicated by a cross (X). The nominal limit curve is in P.

Both figures show a plate edge supposed to have a square bevel.

In case A the nominal size need not be changed for the part. In case B the nominal size must be reduced for the part so that the limit curve is moved from P to P1. This displacement is not constant but may vary along the curve depending on the connection angle.

All types of fixed bevels are affected by this change as illustrated in another figure below

Figure 1:26. Change of nominal contour.

In this case the part size is expanded, being moved from P to P1.

The facility to re-calculate the part geometry is activated by the environment variable name SBH_BEVEL_ADJUST but also supposes that the option in product number 10517 ("Variable Bevelling in Plates and Profiles") is available.
