Symbol Editor provides a user-friendly interface in which you can easily create new or modify existing XML-based or ASCII symbols files for use in Isogen drawings. The software allows you to graphically define and modify a component, and save it to an XML-based file or export the redefined symbol to an Isogen ASCII file so that it can be used in your generated isometric drawings.
Understanding SKEYs
All components generated by Isogen are defined by a two to four character code called an SKEY, or symbol key. The first two characters define the type of component, such as globe valve or concentric reducer, and the last two characters define the end type, such as flanged, butt welded, or screwed. For example, the SKEY VGFL denotes a flanged (FL) globe valve (VG). You can specify an appropriate end condition by replacing the ** characters in the SKEY with one of the set of characters listed in the table below.

-
Components such as miter 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.
-
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.
