P-line Identification

Each p-line is identified by a two, three or four letter code (known as its PKEY) which identifies its relative position in the 2D profile

Note:

Each p-line is extruded in the design model to represent a line running along the length of a section.

The most commonly referenced PKEYs use the following naming conventions (each profile uses only a subset of these):


BBH	Bottom bolt hole
BBHL	Bottom bolt hole, left
BBHR	Bottom bolt hole, right
BLW	Bottom left of web
BLWT	Bottom left web top
