ACE Data Exchange & Interoperability 2 — Questions and Answers
Question 1: Which Autodesk format is specifically designed to package BIM data, geometry, and metadata for cross-platform sharing without requiring the originating application?
- IFC (Correct answer)
- FBX
- AXM
- RVT
Correct answer: IFC
IFC (Industry Foundation Classes) is an open standard for BIM data exchange that is application-neutral.
Question 2: When exporting a Revit model to IFC, which element property controls how Revit categories map to IFC entity types?
- IFC Export Settings (Correct answer)
- Object Styles
- Project Parameters
- Shared Parameters File
Correct answer: IFC Export Settings
IFC Export Settings in Revit allow you to define how Revit categories and elements map to IFC entity classes.
Question 3: A Civil 3D user needs to share a road corridor model with a Revit structural engineer. Which workflow best preserves geometric accuracy?
- Export corridor to IFC and link into Revit (Correct answer)
- Send the DWG drawing file only
- Export to PDF and embed dimensions
- Use Autodesk Docs sharing without export
Correct answer: Export corridor to IFC and link into Revit
Exporting a Civil 3D corridor to IFC and linking it into Revit preserves 3D geometry and metadata for structural coordination.
Question 4: What is the primary purpose of the Autodesk Platform Services (APS) Model Derivative API in a data exchange workflow?
- Translate design files into web-viewable formats and extract metadata (Correct answer)
- Generate new parametric models from scratch
- Synchronize drawings to a local file server
- Manage user authentication across Autodesk products
Correct answer: Translate design files into web-viewable formats and extract metadata
The Model Derivative API translates source files (RVT, DWG, IPT, etc.) into SVF/OBJ/IFC and extracts property data for downstream use.
Question 5: Which file format should be used when exchanging complex mechanical assemblies between Autodesk Inventor and a non-Autodesk CAD system to preserve feature history?
- STEP (STP) (Correct answer)
- DXF
- FBX
- DWF
Correct answer: STEP (STP)
STEP (ISO 10303) is the industry-standard neutral format for exchanging solid model geometry and can carry assembly structure between different CAD systems.
Question 6: In Autodesk Fusion, what does 'Send to' functionality accomplish when used with Autodesk Docs?
- Uploads the current design to a specified Autodesk Docs project for team access (Correct answer)
- Emails the design file as an attachment
- Creates a static PDF snapshot of the design
- Converts the design to DXF for laser cutting
Correct answer: Uploads the current design to a specified Autodesk Docs project for team access
'Send to Autodesk Docs' from Fusion pushes the live design file to a cloud project hub for collaborative access.
Question 7: When using Navisworks to aggregate models from multiple disciplines, which file format allows Navisworks to cache the combined model for faster reloading without the source files?
- NWD (Correct answer)
- NWF
- NWC
- IFC
Correct answer: NWD
NWD (Navisworks Document) is a self-contained file that embeds all model geometry and data, removing the dependency on source files.
