An SKEY is always four characters long and splits into two distinct parts:
In AutoCAD Plant 3D , generating flawless isometric drawings directly depends on two properties: and Iso Symbol SKEY (Symbol Key). These properties act as the DNA of your piping components, telling the isometric engine exactly how to represent a 3D model as a 2D symbol on a drawing.
Are you struggling with a specific component mapping, or do you need a list of the ?

When you place a component in the 3D model (e.g., a gate valve), the part has several properties:

Navigate to your project folder and open IsoSkeyMap.xml using a text editor like Notepad++ or VS Code.
The last two characters of your SKEY do not match the end types of your connecting piping.
