Speckle currently supports Plant 3D versions: 2026 & 2027. The Plant 3D connector works on Windows only.

​
Setup

1

Install the connector

Install your Plant 3D connector
2

Open the Plant 3D connector

  1. In Plant 3D, select the Speckle tab in the ribbon.
  2. Select Speckle to open the Plant 3D connector.
  1. Select Sign in if you haven’t linked your Speckle account.
    Login
  1. Make sure your version of Plant 3D is one of the supported versions.
  2. Uninstall and reinstall your connector.
Don’t select Run as administrator when installing: that installs the connector for the administrator account, not yours. Double-click the .exe, or right-click it and select Open.
Installation issues can also be caused by conflicting plugins.If you’re still experiencing problems, report it in our Community Forum and include:
  • Your application version
  • Your Speckle connector version
If your connector window is floating, try docking it to your application to fix blank UI issues. For major issues, you can sometimes find a log file in your directory at AppData\Roaming\Speckle\Logs. Report your problem in our Community Forum and include your application version, your Speckle connector version, and a copy of the log.
Signing in opens a browser page for your Speckle server. If it doesn’t open, or it never returns you to the connector, check that you can reach your server in your browser, update the connector to the latest version, and try again.
Older connector versions sign in through Speckle Desktop Services, which is deprecated. Update the connector to the latest version. If you must stay on the older version, search for Speckle Desktop Services in Windows search and run it before signing in.
All Speckle connectors are installed like any other program. You can uninstall them directly from your system’s Applications. For a full uninstall, also remove Speckle Desktop Services if it is installed.
You can always download the latest version of the connector in the web app. If a new version of the connector is available, you will also see a notification in your connector UI.

  1. Your model is now published to Speckle and is available to the rest of your team.
You can publish Plant 3D objects such as:
  • pipes
  • inline assets, including fittings and valves
  • equipment
  • P&ID objects, including assets and line segments
You can also publish supported AutoCAD drawing entities, including lines, curves, text, hatches, solids, meshes, and blocks. Plant 3D objects without a dedicated conversion are published using their available display geometry when possible.
Objects linked to the Plant 3D project database include their available project data, such as tags, nominal dimensions, and other fields associated with the object. These fields are grouped under P&ID in the object’s properties in Speckle.Extension dictionary and other available object properties are also included. The exact fields depend on the object’s class and the data defined in your Plant 3D project.
Plant 3D objects are published with display geometry that can be viewed in Speckle. Composite objects are broken down into supported geometric parts while remaining a single selectable object with their Plant 3D properties attached.
Published objects are organized by their Plant 3D drawing layers. Their original layer, color, and material information is included when available.
The connector uses the display geometry available from Plant 3D. An object may publish without geometry if Plant 3D cannot provide geometry that the connector can convert. Its available properties may still be published.
New model creation defaults to your current drawing’s file name. You can edit the model name before publishing.
In the viewer, select the View Modes button in the side bar, and switch the view mode to Shaded. If you still don’t see your object colors, let us know in our Community Forum
Image texture files are not supported. Speckle does not transfer bitmaps or other image maps (such as JPG or PNG files) embedded in materials from the source application.Speckle does carry PBR-style material data in general—where a connector maps to it, materials can include properties such as base colour, opacity, metalness, roughness, and emissive colour. That is not the same as shipping texture images: you get numeric material parameters, not image assets used for wood grain, brick patterns, and similar in the authoring tool.Different materials can still appear separately in the destination with distinct colours and PBR fields. What you see may look closer to a consistent shaded or PBR preview than to the full render-appearance with image maps in tools such as Revit or SketchUp. To use image textures in your target application, apply or remap them locally after you publish or load.
After you publish a Speckle model, click on the Report button to see any errors that may have occurred. Click on any item in the report to highlight that item in your application. Some objects may not be supported for publishing.

Loading a Model

The Plant 3D connector is publish-only.
If you would like to be able to load a model into Plant 3D, please reach out on our Community Forum: https://speckle.community/c/features Include the following information: - Which application your Speckle model is published from - Why you want to load your model into Plant 3D- How frequently you would use this workflow (daily, weekly, monthly, longer).
