An SKEY is typically a four-character code (like VBFL for a flanged ball valve) found in the component’s properties. autocad plant 3d iso symbol skey
An SKEY is a unique, hard-coded or user-defined string attribute embedded within a Plant 3D part ( .pcat or .pcf ) that the IsoConfig.xml file reads to determine which block to insert and how to orient it during isometric generation. | | Valve draws as a straight pipe

| Problem | Likely Cause | Solution | | :--- | :--- | :--- | | Red "X" on isometric | SKEY not found in IsoSymbolStyles.dwg | Copy the missing block from a working project or create it. | | Valve draws as a straight pipe | SKEY is blank or set to PIP (pipe) | Open spec and assign correct valve SKEY (e.g., VAG ). | | Wrong symbol (gate instead of globe) | Spec points to wrong SKEY | Change SKEY in spec editor to VGL (globe valve). | | Flanges missing on isometric | SKEY is FL (lap joint) instead of FLW (weld neck) | Correct the flange’s SKEY in the spec. |
