Sometimes you want a family of valves (AV??) to share the same base logic but use specific blocks. In IsoSkeyAcadBlockMap.xml , you can use question marks as wildcard placeholders.
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 engine maps the SKEY to a specific 2D graphics block and end-type behavior. Structure of an SKEY
What SKEY Is and Why It Matters SKEY (symbol key) is effectively a code assigned to piping items (fittings, valves, flanges, equipment nozzles, specials) that tells the ISO style engine which graphic to place on an isometric. In Plant 3D, components in the 3D model carry properties — manufacturer, specification, class, size, rating, and crucially, SKEY. When generating an isometric, the ISO style consults the component’s SKEY and looks up a corresponding symbol in the ISO symbol library or mapping table. This mapping ensures that a globe valve, gate valve, elbow, reducer, or blind is consistently represented with the correct symbol, orientation, and any annotation attributes (tag, size, material). autocad plant 3d iso symbol skey
Set to FILTER (or VALVE , depending on your XML mapping) and Iso SKEY to STCS .
An SKEY, or Symbol Key, is a four-character or two-character alphanumeric code assigned to piping components in the Plant 3D catalog and spec. It tells the isometric engine (Isogen) two critical pieces of information:
Located within your project's Isometrics folder, this XML file acts as the translator. It looks at the TYPE and SKEY from the model and maps them to a specific and Block Name . 3. The IsoSymbolStyles.dwg Sometimes you want a family of valves (AV
Use code with caution. Save and close the XML file. Step 4: Update Your Catalog and Spec Open the .
Navigate to your project folder and open IsoSkeyMap.xml with an editor like Notepad++.
: Once your block is saved in the drawing, go to your Spec Editor . Find your component and update the ISO SKEY field to match your new identifier. Open the file named
In AutoCAD Plant 3D, isometric drawings (Isos) are vital deliverables for piping design. These drawings rely heavily on a combination of specific symbols and two key properties: and SKEY (Symbol Key) .
