Define the specific end-connection or style of that component (e.g., FL for Flanged, SW for Socket Weld, SC for Screwed/Threaded).
stands for Symbol Key . It is a unique, short text string assigned to every parametric component (fittings, valves, flanges, and equipment) within a Plant 3D spec.

A is a four-character alphanumeric code used by the Iso engine (IsoIsogen) to determine how a 3D piping component is represented on a 2D isometric drawing. This mapping architecture relies on a file named
Navigate to your project directory: Your Project > Isometrics > [Your Iso Style, e.g., Final_ANSI] . Open the file named . Open the Block Editor ( BEDIT ).
The Symbol Key (SKEY) is the invisible link between your 3D model’s specification and the 2D representation on an isometric drawing. Misunderstand the SKEY, and your isometrics will look chaotic. Master it, and you gain complete control over your project’s deliverables.
Understanding SKEYs requires working with two primary project files: IsoSkeyAcadBlockMap.xml : Located in the project's

Add . Create AutoCAD Points ( POINT ) at the exact locations where the pipe connects to the symbol.
AutoCAD Plant 3D is the industry standard for creating piping and instrumentation diagrams (P&IDs) and 3D piping models. One of its most powerful features is the automated generation of isometric drawings (Isos).
Defines the graphical representation, behavior, or end connections (e.g., BW for Butt Weld, SW for Socket Weld, FL for Flanged).
