If you have recently completed an AutoCAD course in Hyderabad and are preparing for job interviews, it’s essential to familiarize yourself with common AutoCAD interview questions. These questions help assess your knowledge and practical skills in design and drafting. Below is a comprehensive list of the most frequently asked AutoCAD interview questions along with detailed answers.

1. What is AutoCAD?

AutoCAD is a computer-aided design (CAD) software developed by Autodesk. It is widely used by architects, engineers, and designers to create precise 2D and 3D drawings. It allows users to draft, edit, and annotate designs efficiently.

2. What are the main features of AutoCAD?

Some of the key features of AutoCAD include:

  • 2D Drafting and Annotation
  • 3D Modeling and Visualization
  • Customizable Interface
  • Data Extraction and Linking
  • Parametric Constraints
  • Collaboration and Cloud Storage Integration

3. What are the different file formats used in AutoCAD?

AutoCAD supports multiple file formats, including:

  • DWG (Drawing File Format) – The native file format of AutoCAD.
  • DXF (Drawing Exchange Format) – Used for data exchange between different CAD applications.
  • DWF (Design Web Format) – A format for sharing and publishing designs.
  • PDF (Portable Document Format) – Used for printing and sharing drawings.

4. What is the difference between model space and paper space in AutoCAD?

  • Model Space is where the actual design and drawing take place. It represents a full-scale workspace.
  • Paper Space is used for creating layouts, adding annotations, and preparing designs for printing.

5. How do you create a new layer in AutoCAD?

To create a new layer in AutoCAD:

  1. Open the Layer Properties Manager by typing LA in the command line.
  2. Click New Layer.
  3. Enter a layer name and set its properties (color, line type, line weight, etc.).
  4. Click OK to save changes.

6. What are the different types of line types in AutoCAD?

AutoCAD provides various line types such as:

  • Continuous
  • Dashed
  • Dotted
  • Hidden
  • Center

These line types help in differentiating various elements of a design.

7. What is the purpose of the OFFSET command in AutoCAD?

The OFFSET command is used to create parallel copies of lines, circles, arcs, or polylines at a specified distance. This command is useful in architectural and mechanical drawings.

8. What is the difference between the EXTEND and TRIM commands?

  • EXTEND allows you to extend a selected line to meet another object.
  • TRIM removes unwanted parts of an object up to the nearest boundary.

9. What is the use of the BLOCK command in AutoCAD?

The BLOCK command is used to create reusable objects or symbols in a drawing. It helps in reducing repetitive work and maintaining consistency.

10. How do you insert a block in AutoCAD?

To insert a block:

  1. Use the INSERT command.
  2. Browse for the block file or select an existing block.
  3. Set the insertion point, scale, and rotation angle.
  4. Click OK to place the block.

11. What is the function of the SNAP command in AutoCAD?

The SNAP command restricts the movement of the cursor to specified increments, helping in precise drafting.

12. What is the difference between POLYLINE and LINE in AutoCAD?

  • LINE creates individual segments, each acting independently.
  • POLYLINE creates a series of connected segments that act as a single object.

13. What are the different coordinate systems used in AutoCAD?

AutoCAD supports the following coordinate systems:

  • Absolute Coordinate System – Uses exact X, Y, and Z coordinates.
  • Relative Coordinate System – Defines a point relative to the previous point.
  • Polar Coordinate System – Uses distance and angle measurements.

14. What is the use of the DIMENSION command?

The DIMENSION command is used to add measurements to a drawing. It includes linear, angular, radial, and aligned dimensions.

15. How do you print a drawing in AutoCAD?

To print a drawing:

  1. Use the PLOT command.
  2. Select the printer/plotter.
  3. Choose the paper size and layout.
  4. Set the scale and preview the print.
  5. Click OK to print.
