Break a design into its parts with Extract Parts

Let Vizcom detect the discrete objects and components in your image, extract each one as its own image, and generate structured Bill of Materials (BOM) data you can export.

​
When to use Extract Parts

Extract Parts turns a single concept image into a set of separable components — useful when you need to isolate, reuse, or document the pieces that make up a product. Use Extract Parts when:
  • Isolating components from a product render for reuse
  • Generating clean, separated images of each part
  • Producing a first-pass Bill of Materials for a concept
  • Preparing parts for handoff, costing, or assembly discussion
It lives in the Extract block in Workbench, alongside Extract Colors and Extract Material.

​
How to use Extract Parts

Extract Parts reads from a connected image, detects the parts, and lets you curate the list before extracting.

​
Using Extract Parts in Workbench

  1. From the toolbar, add an Extract block and connect a drawing or image to it.
  2. Open the Parts tab. Vizcom detects the parts automatically and shows them in the Part list.
  3. Curate the list:
    • Check or uncheck parts to include them. Drag across the checkboxes to toggle several at once.
    • Click a name to rename a part, or remove parts you don’t need.
    • Option-click (Alt-click) a part to isolate it; click again to restore the full list.
    • Use Type to add part… to add a component the detector missed.
  4. Optionally Re-detect parts or Revert to Original from the header controls.
  5. Click Extract N parts to generate a separate image for each selected part. Each one lands as its own element on the canvas.
  6. Click Export BOM to download a CSV of the parts and their estimated attributes.
The BOM CSV includes fields like category, color, material, surface finish, dimensions (W/H/D in mm), manufacturing process, weight estimate, cost tier, quantity, and assembly relationships. These are best-effort AI estimates, not measured specifications — fields the model can’t infer are marked N/A.

​
Best practices when using Extract Parts

  • Start from a clear, well-lit image
    • Distinct, unobstructed parts detect more reliably than overlapping or low-contrast ones.
  • Curate before extracting
    • Rename parts to meaningful labels — the names are sent with the extraction and help condition each generated image.
    • Deselect parts you don’t need so you only spend a generation on the ones that matter.
  • Treat BOM data as a starting point
    • Use it to kick off costing or documentation, then verify dimensions and materials against your real specs.

​
Tips

The part list is capped at 10 parts, and the add-part field disappears once you reach the limit. If a design has many small components, focus the list on the parts that matter most for your downstream work.

Next steps

  • Use Extract Colors on the same image to capture its palette alongside the parts.
  • Bring extracted parts into a new Workbench composition to rebuild or re-style the product.
  • Export the BOM to seed a costing or specification document.
