Hence it is important to learn AutoCAD so you can answer various interview questions proactively.
Basic AutoCAD Interview Questions And Answers
The followings are the AutoCAD basic interview questions and answers for freshers AutoCAD designers:
Q1. What is AutoCAD?
AutoCAD is a platform for all types of designers- architects, interior designers, and engineers to draft drawings or designs digitally, with ease and accuracy. All kinds of designs from simple to complex can be created on a single platform that is supported by cloud storage and artificial intelligence. You can work on large projects with big teams by collaborating with everyone in real-time to create amazing designs on the go.
Q2. What is the use of AutoCAD?
AutoCAD is used to design, draft, and plan technical designs and drawings in the professional space by engineers, interior designers, and architects. Through AutoCAD, designing is possible in any dimension, be it 2D or 3D, and in any unit as well. AutoCAD helps to create visuals or designs relevant to even fields like fine arts or mathematics. Creative pieces like interiors, garments, graphics, or sets meant for shooting or display as well as something very technical such as electric systems, tools, and maps related to civil engineering can be created using AutoCAD.
Q3. How is AutoCAD different from other apps or platforms of a similar kind?
The platform facilitates working with all kinds of units- feet, inches, etc. For example: If you are working on a jewelry design, you could decide on the precision level. You can set it as per your needs- be it ¼ or ⅛. The accuracy is great even with minute detailing. Compared to Archicad, and DraftSight, AutoCAD saves time. AutoCAD offers ‘infinity space’ so you don’t have to make new files each time you start working on big projects.

Q4. What kinds of designs can be made using AutoCAD?
- Architects can use AutoCAD to build blueprints and sketches for both personal and public spaces like homes, schools, cafes, malls, etc.
- Interior designers can use the software to imagine and create interiors and exteriors of any space or infrastructure possible, from cafes to dining areas to schools.
- Sculptures, wood carvings, engravings, and experimental art pieces can be drafted by fine artists.
- A mechanical engineer can create manufacturing processes to design motor parts, robots, and other innovative objects.
- An electrical engineer can map out electrical systems, while a civil engineer can use AutoCAD to design roads, bridges, highways, etc.
Q5. What are the features of AutoCAD?
There are many features of the platform:
- 3D scanning, photorealistic rendering, and mesh modeling, among others.
- You can learn new features, and key combinations each day while learning and creating new things. One of the top notable features is 3D printing.
- Another feature is the ‘Isometric tool’. When one opens the platform, a grid is seen where designs are visible in 2D with only two views- top and side. But the isometric tool allows one to view it from three sides.
Q6. What are the benefits of AutoCAD?
This platform is driven digitally and thus has successfully replaced manual drafting or drawing. Since it was one of the first platforms of its kind, it has been in the top position ever since it came into inception. It is beneficial for designers because it helps in better drafting, and planning of the designs. Apart from designing, one can manage the costs related to the infrastructure and collaborate with others on a database of the same.
Q7. What is your favorite tool from the platform and why?
Two AutoCAD tools because of their benefits- ‘trim’ and ‘line extends’ are worth mentioning. Both can help you if you do not have proper or complete measurements. In case you do not have the length of a line at the given moment and need to join that with another shape or object, the tool of ‘line extend’ will still help you connect them nonetheless by extending the line according to the design and with accuracy. They make things easier, with minimal effort and input.
Q8. What are the most useful and common key combinations that have made your work easier?
The command box stores all the AutoCAD shortcut keys for common actions. For example, the small letter ‘l’ is used to construct a line. When you drift over an object for dimensioning, the dimension or DIM command automatically previews a suitable dimension type to use. Either key can be used for direct action, or the commands can be entered. It even gives you the basic steps on how to use a tool, making the process easier and faster.
Q9.What are the distinctions between AutoCAD and other CAD programs?
AutoCAD is a widely used CAD program that differs from other CAD applications such as SketchUp, SolidWorks, and CATIA in various ways. Some of the distinctions are as follows:
- AutoCAD is a general-purpose CAD program, whereas SolidWorks and CATIA are industry-specific.
- AutoCAD is mostly used for 2D drawing and design, whereas other programs are utilized for 3D modeling and design.
- As compared to competing applications, AutoCAD offers a simpler user interface, making it easier to learn and use.
Q10. What is a workspace in AutoCAD, and how do you create one?
In AutoCAD, a workspace is a collection of toolbars, menus, and other user interface components that are configured to fit a particular job or user preference. In AutoCAD, you can create a workspace by selecting “New Workspace” from the “Workspace” drop-down menu. The workspace may then be saved with a unique name after you have customized the user interface components.
Q11. In AutoCAD, how do you alter or build a block?
In AutoCAD, use the ‘Block Editor’ tool to adjust the geometry, characteristics, and other aspects of a block. To make a block, use the ‘Create Block’ command and choose the items to include in the block. You may also give the block a name and other features.
Q12. What are the advantages of using AutoCAD software?
The following are the benefits of utilizing AutoCAD software:
- It saves time and effort while sketching and designing.
- It enables precise and accurate measurements and dimensions.
- It makes team members’ collaboration and communication easier.
- It boosts productivity and efficiency throughout the design process.
It has a variety of tools and capabilities for designing 2D and 3D designs.

Q20. Why is AutoCAD WS more popular among mobile users?
AutoCAD WS (Web Service) is a web app that acts as an interface for viewing designs on the go. It is like a mini version of AutoCAD. For example, if a .dwg file is shared with someone who does not have AutoCAD installed, it can be opened on a website conveniently and viewed using the WS. Changes can be made there too as it is managed by the cloud, and is not even limited by licensing.
Q21. What is the procedure for removing the empty layers?
The empty layers can be removed by picking the layer, clicking right, and choosing the option to pick and delete the layer.
Q22. What advanced AutoCAD commands do you commonly employ in your work?
Here are some advanced AutoCAD commands that intermediate designers may find useful:
- ARRAY: A pattern of items created in a rectangular, polar, or route array.
- ALIGN: Used to align items along a line or between two points.
- Trim or Extend Lines: Arcs, or polylines to other objects or set bounds with TRIM.
- OFFSET: Creates a parallel replica of an item at a certain distance.
- HATCH: A pattern or plain color used to fill an enclosed area.
Q23.How do you make a 3D model in AutoCAD, and what are some crucial factors to consider?
With AutoCAD, you may use functions like EXTRUDE, REVOLVE, and SWEEP to construct a 3D model. While building a 3D model, keep the following points in mind:
- Plan the design and layout.
- Organize and distinguish things in the model by using layers and colors.
- Check that the model is correctly sized and aligned.
- Take into account the materials and textures that will be used in the finished design.
Q24. What is an AutoCAD viewport, and how can you utilize it to design layouts?
In AutoCAD, a viewport is a rectangular region on a layout or paper space that displays a section of the model space. Viewports may be used to produce numerous views of the model and display them on a single page. You can use the MVIEW command to establish a viewport and then alter the viewport characteristics such as scale, view style, and layer settings.
Q25. In AutoCAD, what is the difference between a block and an xref, and how do you utilize them?
A block is a group of objects that may be reused throughout a drawing, but an xref (external reference) is a distinct drawing file that is put as a reference into the current drawing. Blocks are good for repeating parts in a design, but xrefs are useful for referencing external designs or collaborating on a project with others.
Q26. How do you utilize dimensioning, hatching, and text tools in AutoCAD to make excellent drawings?
To utilize AutoCAD’s annotation tools, choose the relevant tool from the toolbar or menu and then set the annotation’s placement and parameters. In Autocad to add dimensions to a design, for example, use the DIMENSION command and then define the dimension’s distance, angle, and font style. Add hatching to an area, use the HATCH command and then provide the area to be hatched as well as the hatch pattern to be utilized. To add text to a design, use the TEXT command and then define the text’s placement, font, and size.
Q27. How do you deal with layers in AutoCAD, and why are they important?
Layers are used in AutoCAD to organize and manage items in a design. Each layer can have its own set of characteristics like color, line type, and visibility. Intermediate designers should be proficient in establishing and maintaining layers in their designs as it aids in drawing organization and enables more efficient editing and modification. The LAYER command or the Layer Properties Manager may be used to create, rename, remove, and modify layers.
Advanced AutoCAD Interview Questions
The followings are the AutoCAD interview questions and answers for advanced AutoCAD designers:
Q28. What is the process to draw a line more than one time and save it automatically?
When a new line needs to be drawn, the software opens up a new file in a new session to write the file. AutoCAD allows saving multiple drawings for each session. The files are saved in the file extension .dwg and it can be modified in the browser itself.
Q29. What are the steps that enable the drag-and-drop feature in Autocad?
There is a way to drag and drop the elements by the use of “NOUN” and “VERB” in a dialogue box. It allows the object to move from one place to another. In the same way, the removal or editing function can be done by using “MOVE and ERASE”.
Q30. What are the features corrected by AutoCAD?
AutoCAD detects the problem and rectifies it by removing the corruption with the drawing parts. With the option of even adding additional vertices, it adds vertices to the polylines. The error can be corrected or prevented by finding out the exact location of the poly-line that has zero vertices.

Q31. What is a default drawing directory, and how to set it up?
A default drawing directory has subdirectories under it. It contains the applications which are going to be used. By using the drag-and-drop features, those applications can be placed in the default directory. The properties for the application are selected from the menu and dialogue boxes are displayed on the front.
To create one, click on the command prompt, enter REMEMBERFOLDERS, and then enter 0. Right-click the product shortcut icon and choose ‘properties’. On the Shortcut tab, in the ‘Start In’ box, enter the desired default folder path for opening or saving the files.
Q32. How can you copy a closed drawing?
It can be done by the ‘designer center’ in the toolbar of Autocad. By using the ‘tree view’ option, a copy of the closed drawing can be generated easily.
Q33. How can you hide the specific layers when plotting in AutoCAD?
To hide the specific layers while plotting, you can either turn them off or freeze them. The default layer can be turned on or off as per the need.
Q34. What is the process of copying the dimension styles from one drawing to another in AutoCAD?
Copying dimension styles requires setting up the particular dimension style. To copy a dimension style, a new document will have to be created. After that, the document will be saved as a drawing template. A new reference will be created by the new drawing template document and it will show all the options to edit. Drawing can be done by seeing the current drawing and the dimension style would be the same as the original picture. AutoCAD tools can be used from the design center to copy the dimension styles from one drawing to another easily.
Q35. How can you remove the empty layers from the drawing?
The layers can be removed only when the object residing in the layers is removed. When the object is removed, the layer becomes empty. The EXPORT command can remove the layer from the drawing, which results in creating a DXF file of the same. You can edit the dxf file in a text editor afterward.
Q36. How can a spring, spiral, or screw thread be made?
To make a spiral or screw thread, use an AutoLISP routine such as a spiral.1sp, it will create a spiral path accordingly. Then you can use the EXTRUDE command with a reference object, using the spiral as the path.
Q37. How can you assign the keyboard characters or function keys for AutoCAD commands?
By editing the ACCELERATORS section of the AutoCAD menu file, One can assign keyboard characters to Autocad commands to use later.
Q38. What will you do if the ‘Enter Attributes’ dialogue doesn’t display?
Two variables control this function- ATTREQ and ATTDIA. To see the ‘Enter Attributes’ dialogue, make sure that both the variables are set to 1 and not 0.
Q39. In what situation does the command prompt appear instead of dialogue boxes?
If a file command is imported from a script or AutoLISP/ ObjectARX/ ADSRX, it is then that a command prompt appears instead of a dialogue box.
Q40. What is the command that is used to rotate the grid at 45 degrees?
To rotate the grid at 45 degrees, the command UCS is used.
Q41. What will you do when command prompts appear on the command line instead of the ASE dialogue box and plot dialogue box?
ICMDDIA variable runs the display of dialogue boxes. To enable these dialogue boxes, CMDDIA must be set to 1.
Q42. How can you open a drawing file that was created with the automatic save features?
AutoCAD files have an extension of .dwg and it will only open files with that. To open the drawing files, they must be renamed using Explorer or DOS prompt. If you are using EXPLORER, you have to be sure that the option of “Hide file extensions for known file types” is not enabled. After the file is copied, you can rename and use the OPEN command to open the drawing.
Q43. What do you understand by aligned dimension?
The aligned dimension is a linear dimension that measures the distance between two points. The dimension line for an aligned dimension is parallel to the line between points.
Q44. What are polar coordinates?
Polar coordinates are the value that locates a point in space describing its location relative to the last point.
Q45. Which filename extension is used to indicate a compiled text font?
The TXT file extension is used to signify a compiled text font in AutoCAD.
Q46. How many entity colors are supported by AutoCAD?
255 entity colors are supported by AutoCAD.
Q47. Which polygon command cannot draw shapes?
A rectangle can not be drawn using the polygon command.
Q48. What is an object snap mode?
The object snap mode or tool helps us to pick up and locate specific points or grips of an object like the midpoint, endpoint, and the like.
Q49. What are hatch patterns?
A pattern of lines, dots, and other related shapes that fill a closed area is called a hatch pattern.
Q50. What is the graphics window in AutoCAD?
The graphics window is the main screen in AutoCAD software. It contains the drawing area, toolbars, menu bars, command window, and status bar.
Q51. What is the use of the MIRROR command?
