What command is used to create a circle in AutoCAD?
Correct Answer
A. Circle
Explanation
The Circle command in AutoCAD is used to create a circle by defining its center point and radius or diameter. It is a fundamental drawing tool that allows users to specify the exact size and location of a circle. Unlike the Arc or Ellipse commands, which create partial curves or ovals, the Circle command generates a complete circular shape. This tool is widely used in both 2D and 3D designs for drafting round objects, cutouts, or other circular features. Mastering the Circle command is essential for precision in many technical drawing tasks.

Which command allows you to move an object in AutoCAD?
Correct Answer
C. Move
Explanation
The Move command in AutoCAD allows you to relocate objects from one place to another without altering their size or shape. By selecting an object and specifying a base point, users can drag or type precise coordinates for the object’s new location. Unlike Copy, which duplicates the object, Move simply changes its position. This command is often used to adjust the placement of elements within a drawing, ensuring correct alignment and spacing. Understanding the Move command is crucial for efficiently managing layouts and designs in AutoCAD.
3.
How do you display the full model space in AutoCAD?
Correct Answer
B. Zoom Extents
Explanation
Zoom Extents is a crucial AutoCAD command that adjusts the view to display all objects within the drawing. It ensures that every element, no matter how far or small, becomes visible within the model space. This command is especially useful when working with large or complex drawings, as it eliminates the need to manually pan around. Zoom Extents fits the entire drawing within the viewport, giving users a comprehensive view of all elements. It helps streamline navigation, saving time when locating distant or out-of-frame objects.
4.
Which tool helps you snap to specific points, like midpoints or endpoints, in AutoCAD?
Correct Answer
B. Object Snap
Explanation
Object Snap (Osnap) in AutoCAD is an essential tool that allows users to snap precisely to predefined points on objects, such as endpoints, midpoints, intersections, and centers. This enhances accuracy in placing, moving, or modifying objects by automatically detecting the exact points of interest. Unlike Grid Snap, which forces movement along a grid, Object Snap dynamically adjusts to the specific geometry of objects. It is vital for precision drafting, ensuring that all lines and shapes connect perfectly, especially in detailed technical designs where even minor inaccuracies can cause significant issues.
5.
What command is used to create a 3D solid in AutoCAD?
Correct Answer
B. Extrude
Explanation
Extrude is a command used in AutoCAD to create 3D solids from 2D objects like lines, circles, or polygons. By giving depth to flat shapes, the Extrude command transforms them into three-dimensional models. It is widely used in 3D modeling to create objects with height or depth based on their 2D profiles. This command requires the user to select a 2D object and specify the height or path for the extrusion. Mastering this tool is key for designing more complex and realistic models, particularly in architectural and mechanical drafting.
6.
Which layer property controls the visibility of objects?
Correct Answer
C. Freeze
Explanation
The Freeze property in AutoCAD is used to control the visibility of objects on a specific layer. When a layer is frozen, all objects on that layer are hidden from view, but they remain part of the drawing and can be unfrozen at any time. This differs from turning off a layer, as freezing a layer improves system performance by not processing those objects. The Freeze feature is often used in large or complex drawings to simplify the workspace, making it easier to focus on relevant details without permanently altering the design.
7.
How can you rotate an object by a specific angle in AutoCAD?
Correct Answer
B. Rotate
Explanation
The Rotate command in AutoCAD allows users to rotate objects around a base point by a specific angle. By selecting the object and defining the base point, users can input an exact angle of rotation. This command is useful for changing the orientation of objects to align them with other elements or design requirements. Unlike the Move or Scale commands, Rotate only affects the object's orientation without altering its position or size. Precision in rotation is key, especially in technical drawings where angles must be exact for components to fit or function correctly.
8.
What does the Trim command do in AutoCAD?
Correct Answer
C. Cut objects
Explanation
The Trim command in AutoCAD allows users to cut or shorten objects at a specified boundary or cutting edge. This is particularly useful in cleaning up lines and shapes by removing excess parts that extend beyond a desired point. By selecting a cutting edge and the object to be trimmed, users can quickly eliminate unnecessary sections of the design. Trim helps maintain a tidy and precise drawing, especially in architectural or engineering plans where overlapping lines need to be trimmed for clarity. Understanding the Trim command is vital for efficient and accurate drafting.
9.
Which file type is commonly used to save AutoCAD drawings?
Correct Answer
B. .dwg
Explanation
The .dwg file format is the standard file type for saving AutoCAD drawings. It stands for "Drawing" and is the primary format used by AutoCAD and many other CAD programs. The .dwg file stores all drawing data, including layers, dimensions, colors, and geometry, making it essential for sharing and preserving detailed technical designs. This format supports both 2D and 3D elements, allowing users to save complex designs in a single file. Unlike .pdf or .doc files, .dwg is fully editable, making it the preferred choice for ongoing design work in professional settings.
10.
How do you create an array of objects in a rectangular pattern?
Correct Answer
D. Rectangular Array
Explanation
The Rectangular Array command in AutoCAD allows users to create a grid-like pattern of objects by specifying rows and columns. This feature is particularly useful for duplicating objects in a structured and evenly spaced manner. By inputting the number of rows, columns, and the distance between each, users can quickly replicate objects across a defined area. This command saves time and ensures precision when creating multiple instances of an object, such as chairs in a room layout or bolts on a mechanical part. Rectangular Array is essential for managing repetitive designs efficiently.
