Autocad Plant 3d Iso Symbol Skey ❲GENUINE | Release❳

AutoCAD Plant 3D SKEY (Symbol Key) is a four-character code that determines the graphical representation of a 3D piping component in an isometric drawing. Without a valid SKEY, isometric generation may fail or split. Core SKEY Components An SKEY typically consists of two parts: First two characters : Define the component type for Elbow, for Valve). Last two characters : Define the or specific variant (e.g., for Buttweld, for Flanged). Essential SKEY Mapping Files

Understanding SKEYs requires working with two primary project files: IsoSkeyAcadBlockMap.xml : Located in the project's

folder, this file maps the SKEY to a specific AutoCAD block name. IsoSymbolStyles.dwg

: The block library that contains the actual geometry for the isometric symbols.

Advanced Techniques: Using Wildcards and Long SKEYs

Modern versions of Plant 3D support Long SKEYs (more than 3 characters). This allows for intelligent matching.

For example, instead of one GAV symbol for all gate valves, you can have:

To do this, you do not change the SKEY property in the spec. Instead, use the SkeyMap XML to map the FullDescription or LongSkey: AutoCAD Plant 3D SKEY (Symbol Key) is a

<SkeyMap skey="GATE-150LB-FLANGE" acadBlock="G15" />
<SkeyMap skey="GATE-300LB-FLANGE" acadBlock="G30" />

Then, in your IsoSymbols.dwg, create blocks named G15 and G30 with different sizes (thicker flanges, different bolt patterns).

Part 1: What is an SKEY (Symbol Key) in Plant 3D?

Before we modify anything, we must understand the hierarchy of how AutoCAD Plant 3D draws an isometric.

When you place a component in the 3D model (e.g., a gate valve), the part has several properties: Advanced Techniques: Using Wildcards and Long SKEYs Modern

When you run the IsoConfig and generate the drawing, the Plant 3D ISO engine reads the SKEY from the model. It then looks at the IsoSymbols.dwg file (or your project’s symbol map) and finds the block named GV. It then inserts that block (the 2D representation) onto the isometric line.

In short: The SKEY is the lookup key that tells the ISO engine which 2D block to draw.

How to access it:

  1. Open AutoCAD Plant 3D.
  2. Go to Project Manager -> Isometric DWG Settings.
  3. Click the "ISO Symbol Editor" button.

Inside the ISO Symbol Editor, you will see a grid. Each cell represents a specific SKEY. For example:

Each symbol is drawn using specific rules:


Step 2: Create the New 2D Block

  1. Open your project’s IsoSymbols.dwg.
  2. Copy an existing block. Do not start from scratch. Copy GAV and rename the copy to GAG (Gear Actuated Gate).
  3. Explode the copy and modify the geometry. Draw the gear operator (a small circle or star) on top of the valve stem.
  4. Use the BLOCK command to redefine GAG (ensure 'Scale uniformly' is OFF).
  5. Save IsoSymbols.dwg.

Level 2: Change the SKEY via Spec Editor

This is the preferred method for permanent fixes.

  1. Open Spec Editor from the ribbon.
  2. Navigate to your component (e.g., Ball Valve, 2", Flanged).
  3. Find the SKEY property (often in the “Iso Data” or “Optional” group).
  4. Change it from VAB to VAG if you want it to draw as a gate valve on isometrics.
  5. Save and re-export the spec.
