All components generated by Isogen are defined by a unique code called a symbol key (SKEY). SKEYs contain 2-4 characters; the first two characters define the type of component, and the last two characters define the end type, such as flanged, butt welded, or screwed. You can specify an appropriate end condition by replacing the ** characters in the SKEY with one of the set of characters from the table below.

Some special components such as mitre bends and pulled bends can have special characters in the SKEY to affect its shape, as detailed below.
-
To denote the number of segments, replace the AT sign (@) in the SKEY with an integer value in the range 1 to 9, inclusive. Currently, regardless of the value assigned to the AT sign, the software draws the symbol according to the SKEY-plotted isometric shape.
-
To denote the bend radius, replace the Plus sign (+) in the SKEY with an integer value in the range 1 to 9, inclusive. This is for identification only and is not used for pipe length calculations.
