ACA ACA Design Fundamentals and Workflows 1 — Questions and Answers
Question 1: Which Autodesk application is primarily used for 2D CAD drafting and is a core focus of the ACA certification?
- AutoCAD (Correct answer)
- Revit
- Inventor
- Fusion 360
Correct answer: AutoCAD
AutoCAD is the primary Autodesk application for 2D CAD drafting and is a central focus of the ACA certification exam.
Question 2: What does the term 'UCS' stand for in AutoCAD?
- Universal Coordinate System
- User Coordinate System (Correct answer)
- Unified Construction Standard
- Unit Control Setting
Correct answer: User Coordinate System
UCS stands for User Coordinate System, which allows users to define a custom coordinate system for drawing.
Question 3: In AutoCAD, which command is used to combine two or more overlapping regions or 3D solids into one?
- INTERSECT
- SUBTRACT
- UNION (Correct answer)
- MERGE
Correct answer: UNION
The UNION command combines two or more regions or 3D solids into a single composite object.
Question 4: Which AutoCAD feature allows you to create parametric relationships between objects so they maintain geometric or dimensional constraints?
- Dynamic Blocks
- Parametric Constraints (Correct answer)
- Object Snaps
- Layer Groups
Correct answer: Parametric Constraints
Parametric Constraints in AutoCAD create geometric or dimensional rules between objects that are maintained when the drawing is modified.
Question 5: What is the purpose of the OFFSET command in AutoCAD?
- To move an object to a new location
- To create a parallel copy of an object at a specified distance (Correct answer)
- To rotate an object around a point
- To scale an object proportionally
Correct answer: To create a parallel copy of an object at a specified distance
The OFFSET command creates a new object parallel to and at a specified distance from the original object.
Question 6: In the ACA exam context, what is a 'viewport' in AutoCAD?
- A saved camera position in 3D space
- A window in paper space that displays a view of model space (Correct answer)
- A display panel for tool palettes
- A section of the ribbon interface
Correct answer: A window in paper space that displays a view of model space
A viewport in AutoCAD is a window within paper space (layout) that displays a specific view of the model space drawing.
