There’s a moment on many projects where momentum pauses. Someone asks “Is this dimension allowed?” At that point, the process shifts into static reference materials, a BIM tool, or an engineering review.
That shift is manageable for architects and designers, since they already use the Informed Design Add-in for Revit to configure products within the supplier’s allowable range – but the buying process doesn’t stop with the architect. Clients, procurement teams, and other project collaborators want to evaluate options for a product outside the BIM authoring context.
With the new Informed Design APS Viewer Extension, that same rule-driven validation designers access through our Revit Add-in is now available directly in the web browser.
The Foundation: Autodesk Platform Services Viewer
If you’ve used the Autodesk Viewer through Autodesk Docs (soon to be Forma Data Management), Fusion Team, or Shared Views functionality, you’re already familiar with high-performance 3D model viewing in the browser.
Our Informed Design Viewer Extension is built on that same APS Viewer SDK to enable not only visualization, but rule-driven product configuration and BIM-ready output generation, directly in the browser.
For Product Suppliers
As a supplier publishing products using the Informed Design Add-in for Inventor, you can now open your published releases in the 3D web viewer.
Open a release and preview variants in the web browser
Open the Informed Design Web Portal. In the header navigation, select the Forma hub and project that host your products, then open the Releases tab.
Note: Project Admin–level permission in the Autodesk Docs (Forma Data Management) project is required to access the Releases tab.
Select a product from the list on the left, then choose a release from the table.
Note: Products appear based on the folders selected in the Folders filter. If the list is empty, click the Folders filter button above the list. In the Filter products by folder dialog, select at least one project folder containing published products and click Apply.
Open the release: Click View in 3D at the top of the Releases table. The Informed Design APS Viewer Extension opens in a new browser tab and loads the selected release.
The Informed Design toolbar appears on the far right of the viewer, after the APS Viewer’s standard navigation and selection tools. It includes the following options:
Release details – Displays read-only summary information such as the release date and Revit Family (.rfa) output's Category.
Form – Shows the release’s input parameters, values, and controls, which are editable when the release’s configuration rules allow it.
Variants – Opens a table listing all variants created for the release. From here you can access the web-viewable (.svf) outputs of completed variants and monitor those still in progress.
Preview existing variants: Click the Variants toolbar button to open the variants table. Select any row to display that variant in the 3D viewer.
Configure variants and track output status
If the release is Configurable, you can use the Form to create new variants directly in the 3D viewer. Each validated configuration you generate in the browser automatically becomes BIM-ready content, building your Revit Family (.rfa) library as you go.
Open the configuration form: Click the Form toolbar button to display the release’s configuration form.
Note: For releases published as Static, form controls are read-only. Open the Variants table to browse the supported configuration in its available model state representation(s).
Create a variant: Use the form controls to select the desired values. Once the configuration passes validation rules, click Generate to create the variant.
Note: If a release has the Obsolete status, it can still be opened in the viewer and existing variants can be previewed. However, form controls and the Generate button are disabled because new outputs cannot be created from an obsolete release.
Open the Variants dialog. After you submit a configuration, a new row appears in the Variants table.
Track variants in progress. Two columns track output status:
SVF shows the status of the web-viewable model displayed in the browser.
RFA shows the status of the generated Revit Family (.rfa). For variants that support Revit output, both the web-viewable (.svf) model and the Revit Family (.rfa) are generated in parallel.
Identify BIM-ready variants: When generation completes successfully, a checkmark icon appears in the status column:
When the variant's SVF column is checked, the web-viewable model is displayed in the browser.
When the variant's RFA column is checked, designers with permission can immediately load that Family into their Revit projects through Informed Design's Revit Add-in. This relationship works both ways – when a designer generates a variant .rfa using the Informed Design Add-in for Revit, the corresponding web-viewable .svf is created automatically and appears in the 3D viewer's Variants list.
Variants created through the API
In some releases, the Variants table may contain rows where the Representation column shows “Not specified”, and the SVF and RFA columns display question-mark icons. This occurs when a variant was created through the API.
API-first variants do not require a representation when they are generated (see POST /variants). However, both the .svf (web-viewable model) and .rfa (Revit Family) outputs depend on a representation (see POST /outputs) so their availability cannot be determined automatically.
To resolve this, open the Form and select a representation from the dropdown menu in the dialog footer. The dropdown lists the representations available for the .svf output type. Then click Generate to display it in the viewer.
If the selected representation also supports .rfa output, the Revit Family will begin generating in parallel and you’ll see a progress spinner. If it does not, the RFA column will display a ban icon (circle with a dash), indicating that .rfa output was not made available for that representation in the current release.
For Developers and Partners
The Informed Design Viewer Extension is also available as an embeddable component. This allows suppliers to integrate interactive 3D product exploration directly into their own web platforms.
