To create or customize an ISO symbol in AutoCAD Plant 3D, you need to edit the skey file associated with the symbol. Here are the general steps:
Save and close the Block Editor. Save the IsoSymbolStyles.dwg file. Step 3: Map the New SKEY in IsoSkeyMap.xml

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).
Open the ( BEDIT ) and select the block corresponding to the symbol type you want to modify, or create a brand new block. To create or customize an ISO symbol in
Locate the component, go to its properties, and find the and Iso SKEY fields.
Add a new line matching your custom 4-character SKEY (let’s use VAIV for Valve Instrument Valve): Step 3: Map the New SKEY in IsoSkeyMap
Define the specific end-connection or style of that component (e.g., FL for Flanged, SW for Socket Weld, SC for Screwed/Threaded).
Understanding AutoCAD Plant 3D Isometric Symbols and SKEYs In AutoCAD Plant 3D, isometric drawing generation is a critical deliverable for piping designers and engineers. The system automates this process using a 2D drafting engine that translates 3D pipeline models into standard 2D isometric layouts. At the heart of this translation process is the relationship between the and the SKEY (Symbol Key) .
[VALVE_SYMBOL] Shape= CIRCLE Diameter= 20 FillColor= RED Label= "VALVE" LabelFont= Arial LabelSize= 12
The engine driving this automated drafting process relies on two critical identifiers: and Symbol Keys (SKEY) .
