: First, open your project's catalog in the Spec Editor and navigate to the 'Catalog Editor' tab. Find the component (e.g., a flange). In its properties, you'll see the fields 'Iso Symbol Type' and 'Iso Symbol SKEY' .
Open this file to draw your custom symbol geometry. Use standard AutoCAD lines and arcs. Crucially, you must place using specific block attributes so the engine knows where the pipe attaches. Step 2: Map the SKEY in IsoSymbolMap.xml The isometric engine cannot find the SKEY listed
When you run IsoProject or IsoDrawings , the following deterministic workflow occurs:
For example, the SKEY tells Plant 3D to draw a Ball Valve (VT) with Flanged End Connections (FL) on the isometric sheet. 2. Deciphering the SKEY Matrix: Common Identifiers : First, open your project's catalog in the
AutoCAD Plant 3D comes pre-loaded with hundreds of standard SKEYs out of the box. Familiarizing yourself with these standard prefixes and suffixes simplifies troubleshooting. Common SKEY Prefixes (Component Type) Elbow TE: Tee RE: Reducer FL: Flange VA: Ball/Gate/Check Valve VG: Globe Valve VT: Three-way Valve CO: Coupling PL: Plug CA: Cap Common SKEY Suffixes (End Connections) FL: Flanged BW: Butt Welded SW: Socket Welded SC: Screwed / Threaded PL: Plain End WF: Wafer (common for butterfly valves) SKEY Examples in Action Component Description TYPE Property SKEY Property 90-Degree Butt-Weld Elbow ELBOW ELBW Slip-On Flange FLANGE FLSO Threaded Tee TEE TESC Flanged Gate Valve VALVE VAFG Socket-Weld Ball Valve VALVE VASW 3. How Plant 3D Maps SKEYs to AutoCAD Blocks
Before you can draw a symbol, you have to tell the database which SKEY belongs to which part. This is done in the Catalog Editor:
Modify the geometry. Keep your geometry centered around the and ensure the connection points match the standard flow lines. Save changes and close the file. Step 2: Update the IsoSymbolMap.txt
