SPC CAD
SPC CAD Panel
Bring your 3D models to life inside Grafana. Visualize CAD geometry, overlay real measurement data, and spot quality issues at a glance — all from your dashboard.
Why SPC CAD?
Manufacturing quality teams spend hours switching between measurement software, spreadsheets, and reporting tools. SPC CAD Panel puts everything in one place: your 3D model, your data, and your analysis — live, interactive, and shareable across your organization.
Key Features
Interactive 3D Visualization
Load STL, 3MF, PLY, and ASC files directly into your dashboard. Rotate, pan, and zoom with intuitive trackball controls. Display multiple models side by side for assembly-level inspection.
Feature Annotations
Click any measurement feature on your model to see its data. Annotations combine tables, time-series charts, and custom grid layouts — all populated from your Grafana queries in real time.
Forecasting
See where your process is heading. When paired with the KensoBI SPC Characteristic Datasource, the panel displays forecast trends with upper and lower confidence bands directly on feature charts — helping you act before problems occur.
Point Cloud Deviation Analysis
Overlay scan data on your CAD model with automatic deviation color mapping. A blue-to-red gradient instantly highlights where your part deviates from nominal.
Color-Coded Quality Status
Define rules to color features based on measurement values — green for in-spec, red for out-of-tolerance, or any scheme that fits your workflow. Spot problems without reading a single number.
13 Built-in Templates
Pre-configured annotation layouts for common feature types: point, circle, cylinder, sphere, ellipse, line, rectangle, slot, plane, slab, cone, and more. Select a template and your annotation is ready — or customize it to fit your needs.
Scan Timeline
Navigate through historical scan data with a built-in timeline slider. Play back inspections over time to track process trends and catch drift early.
Getting Started
- Install the plugin in your Grafana instance
- Create a new panel and select SPC CAD as the visualization
- Add a CAD model URL or upload a file (STL, 3MF, PLY, or ASC)
- Connect a data query with your feature measurements
- Click features on the model to create annotations

Installing SPC CAD on Grafana Cloud:
Installing plugins on a Grafana Cloud instance is a one-click install; same with updates. Cool, right?
Note that it could take up to 1 minute to see the plugin show up in your Grafana.
Warning
Plugin installation from this page will be removed in February 2026. Use the Plugin Catalog in your Grafana instance instead. Refer to Install a plugin in the Grafana documentation for more information.

Installing on a local Grafana:
For local instances, plugins are installed and updated via a simple CLI command. Plugins are not updated automatically, however you will be notified when updates are available right within your Grafana.
1. Install the Panel
Use the grafana-cli tool to install SPC CAD from the commandline:
grafana-cli plugins install The plugin will be installed into your grafana plugins directory; the default is /var/lib/grafana/plugins. More information on the cli tool.
Alternatively, you can manually download the .zip file for your architecture below and unpack it into your grafana plugins directory.
Alternatively, you can manually download the .zip file and unpack it into your grafana plugins directory.
2. Add the Panel to a Dashboard
Installed panels are available immediately in the Dashboards section in your Grafana main menu, and can be added like any other core panel in Grafana.
To see a list of installed panels, click the Plugins item in the main menu. Both core panels and installed panels will appear.
