ACE ACE Performance Optimization & Hardware Configuration 2 — Questions and Answers
Question 1: In AutoCAD, which command opens the Graphics Performance dialog to configure hardware vs. software acceleration settings?
- GRAPHICSCONFIG (Correct answer)
- OPTIONS
- PERFMON
- ACADGFX
Correct answer: GRAPHICSCONFIG
The GRAPHICSCONFIG command opens AutoCAD's Graphics Performance dialog, where users configure hardware acceleration, anti-aliasing, and other GPU settings.
Question 2: What Revit performance technique uses a smaller, simplified version of a view to speed up navigation in large models?
- Thin Lines view with hidden elements
- Section Box to isolate a region (Correct answer)
- Detail Level set to Coarse
- Temporary Hide/Isolate
Correct answer: Section Box to isolate a region
Using a Section Box in Revit crops the active 3D view to a specific region, reducing the number of elements Revit must process and dramatically improving navigation speed.
Question 3: Which Inventor assembly performance setting loads sub-assemblies as a single, non-editable mesh to reduce memory overhead?
- Substitute LOD
- Shrinkwrap (Correct answer)
- Derived Assembly
- Envelope Component
Correct answer: Shrinkwrap
The Shrinkwrap feature in Inventor creates a simplified single-body mesh representation of an assembly, dramatically reducing load time and memory when used as a substitute component.
Question 4: For Autodesk Civil 3D, which display setting improves performance by preventing dynamic profile and section views from regenerating continuously during pan/zoom?
- Disabling dynamic input and viewport refresh for data shortcuts
- Freezing surface layers (Correct answer)
- Setting object snap to None
- Turning off UCS icon
Correct answer: Freezing surface layers
Freezing surface display and TIN layers when not actively editing them prevents Civil 3D from continuously recalculating surface triangulations during viewport operations.
Question 5: What Autodesk Navisworks feature should be used to improve real-time navigation performance in large federated models?
- File Unit and Transform options
- Autodesk rendering mode
- Speed and Culling settings in viewport options (Correct answer)
- Clash Detective batchmode
Correct answer: Speed and Culling settings in viewport options
Navisworks' Speed and Culling settings control frame rate targets and automatically hide distant or small objects to maintain smooth real-time navigation in large models.
Question 6: In Revit, which journal file location should be monitored and periodically cleared to prevent slow startup times?
- %LOCALAPPDATA%\Autodesk\Revit\Journals (Correct answer)
- C:\Program Files\Autodesk\Revit\logs
- %APPDATA%\Revit\Cache
- C:\Revit\Backup
Correct answer: %LOCALAPPDATA%\Autodesk\Revit\Journals
Revit writes a journal file for every session to %LOCALAPPDATA%\Autodesk\Revit\Journals; accumulation of thousands of files can slow Revit startup and should be cleared periodically.
