40 AutoCAD Interview Questions and Answers  

Here are 40 AutoCAD basic interview questions with answers and the context of the questions asked. 

How would you define AutoCAD?  

The interviewer wants to assess your understanding of AutoCAD and your ability to explain its purpose concisely.  

Answer: AutoCAD is a Computer-Aided Design software for creating, modifying, and optimising 2D and 3D designs. It provides a platform for precise and detailed drawings in various industries like architecture, engineering, and construction.

2) What is the significance of layers in AutoCAD?   

This question aims to evaluate your understanding of organisation and efficiency in AutoCAD.   

Answer: Layers in AutoCAD help organise and manage different elements of a drawing. They allow for better visibility control, grouping related objects, and ease of editing by providing a hierarchical structure for design components.  

3) How do you create a block in AutoCAD?  

The interviewer is assessing your knowledge of creating reusable content in AutoCAD.  

Answer: To create a block in AutoCAD, use the "BLOCK" or the "BMAKE" command. Select the objects you want to include in the block, specify the insertion point and other options, and give it a name. Blocks allow for efficient replication of objects, reducing file size and simplifying editing tasks. 

4) How can you modify the properties of an object in AutoCAD?  

This question tests your familiarity with object manipulation and customisation in AutoCAD.  

Answer: To modify object properties in AutoCAD, you can use the "Properties" palette or the "Properties" command. Select the object, and you can change various properties like colour, layer, linetype, and more. This allows for precise adjustments and adherence to drawing standards.

6) How can you create a hatch pattern in AutoCAD?  

This question assesses your knowledge of applying patterns to enclosed areas in AutoCAD.  

Answer : To create a hatch pattern in AutoCAD, use the "Hatch" command. Select the enclosed area to be hatched, choose the desired pattern and scale, and specify any additional settings. Hatching is useful for representing materials, textures or indicating areas in a drawing.  

7) What are the differences between absolute and relative coordinates in AutoCAD?   

The interviewer aims to evaluate your understanding of coordinate systems and precision in AutoCAD.   

Answer : Absolute coordinates in AutoCAD specify points based on a fixed origin, such as the intersection of the X, Y, and Z axes. Relative coordinates, on the other hand, define points relative to the last point specified or relative to a predetermined base point. Absolute coordinates provide precise positioning, while relative coordinates offer flexibility during drawing.  

8) How do you use the "Mirror" command in AutoCAD?  

This question tests your ability to mirror objects accurately in AutoCAD.
