CAD & BIM Systems

Upload the STEP File.
Get the GLB, the BOM,
and the Quote.

RenderDraw converts over 30 CAD formats inside workflow blocks. Upload a SolidWorks assembly, a Revit model, or a 200-page DWG set — and your workflow produces a web-ready 3D viewer, a full BOM, dimension extraction, and an automatically priced quote.

How CAD Files Flow
Through a Workflow.

CAD File Input

Uploaded directly, pulled from Autodesk BIM 360, or attached to a Salesforce record

Input

CAD Conversion Block

HOOPS Exchange converts the file to GLB/GLTF. Extracts geometry, hierarchy, metadata, and PMI data

Convert

BOM Extraction

Part list extracted from assembly hierarchy. Part numbers, quantities, materials, and mass properties

BOM

Price Each BOM Line

Datasource block queries Salesforce CPQ or SAP for pricing per part number

Price

3D Viewer Delivery

GLB served via embedded 3D viewer. Customer sees the exact model in the proposal

Autodesk Integration

BIM 360 & Construction Cloud
as a Workflow Source.

Connect to Autodesk BIM 360 or Autodesk Construction Cloud via OAuth 2.0. RenderDraw can monitor project folders for new model uploads, pull the latest approved model version, and trigger a takeoff or conversion workflow automatically.

  • Watch folders — trigger when a new .rvt, .dwg, or .nwd file is uploaded to a BIM 360 project folder
  • Version control — always pull the latest approved model version, not a stale local copy
  • Sheet extraction — for BIM 360 sheets (2D drawing PDFs), use Claude Sonnet vision for takeoff extraction
  • Model coordination — pull clash reports and RFI data from BIM 360 to feed RFI management workflows

Conversion Output

Three Outputs From
Every CAD Conversion.

GLB / GLTF 3D Model

A web-ready 3D model file that loads in any modern browser via the RenderDraw 3D viewer web component. Embed in proposals, portals, or Salesforce records. Supports configuration states, design views, and annotations.

Three.js viewer Embeddable Config states

Bill of Materials (BOM)

Structured JSON BOM extracted from the assembly hierarchy. Part number, description, quantity, material, mass, and any custom properties stored in the CAD file. Mapped to workbook columns for automatic pricing.

JSON BOM Workbook-ready Part metadata

Dimension Extraction

Overall bounding box dimensions, part-level dimensions from PMI annotations, and custom dimension attributes extracted from the CAD model. Used to validate takeoff quantities and generate technical datasheets.
