P-line Identification
- Last UpdatedOct 06, 2023
- 2 minute read
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 (remember that 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):
