4. 3 Point
5. Tangent Tangent Radius
6. Tangent Tangent Tangent

20. How the Magnet feature help us in AutoCAD drafting?

Answer: The magnet feature causes the cursor to "lock" onto object features like end point,
center, midpoint etc when the cursor is within the confines of the marker. Moreover magnet
helps to confirm the exact location that will be snapped to for the subsequent PICK.

Answer: We can take Quick Calculator by pressing Ctrl + 8

25. Which keyboard key cancels any active command?

Answer: <Esc> Key

26. What is the use of JOIN command in AutoCAD?

Answer: It is used to combines a series of finite linear and open curved objects at their
common endpoints to create a single 2D or 3D object.

28. What is the use of BATTMAN command in AutoCAD?

Answer: It is used to modify the attribute information of blocks containing attributes.

29. Which command is used to convert 3D solid and surface into NURBS surface ?
Answer: CONVTONURBS Command

30. Which command is used to add control vertices to NURBS surfaces and splines?
Answer: CVADD Command

31. What is the difference between Zoom Extents and Zoom All?
Answer: Zoom Extent will zoom only all of the geometry in the drawing. Zoom All will zoom
everything. ie, the drawing geometry and the drawing limits (grid area).

32. How do you make a viewpoint active? How can you tell that a viewpoint is active ?
Answer: To make a viewpoint active, place the cursor in the viewpoint and select the left
button on the mouse (LMB). An active viewpoint will have a slightly bolder border around it,
and will show the cursor crosshairs in it.

33. How will you find moment of inertia in AutoCAD?

Answer: Using the VOLUME command we can find the moment of inertia, radius of gyration,
centroid and many more.

34. How will you extract the edges of a 3D solid as 2D geometries?

Answer: We can use XEDGES command to extract the edges of a 3D solid as 2D geometries.
It will reveal the edges of the 3D solid just like a wire frame drawing.

35. When will you use OOPS command in AutoCAD?

Answer: OOPS command is used when we need to restore the last deleted object from the
drawing.

36. How NCOPY command is differ from COPY command?

Answer: NCOPY command will copy nested objects from a block or Xref without exploding
them.

37. Which command is used for checking spelling mistakes in AutoCAD?

Answer: SP command is used for checking spelling mistakes of the selected text. You can
correct the spelling from the Check Spelling Window.

38. How will you draw an infinite line in AutoCAD?

Answer: Using XLINE (XL) command we can create a infinite line from the point of selection.

If you trim this infinite line to a finite length it becomes a simple line geometry.

39. How can you make a text clearly visible in a crowed background ?
Answer: We can use TEXTMASK command to mask the text which will make texts clearly
visible against the crowded background.

40. What is the use of LAYMRG command in AutoCAD? How will you use that?
Answer: It is commonly used when we need to merge layers of multiple objects. And it can
be done like this, Type LAYMRG press enter key then select the objects whose layers you
want to change then press enter again. Select any object of target layer on which you want
to transfer the selected objects and press enter again. All the objects of the selected layer will
be transferred to the end layer and also the selected layer will be removed.

41. What is the use of ISOLATE command in AutoCAD?

Answer: ISOLATE command is used to hide all objects from the drawing area except the
selected objects. Usually this command is used to hide object when we need to get a clean
work area for the ease of drawing.

42. Which keyboard shortcut is used to insert hyperlinks in AutoCAD?

Answer: Ctrl+K is used to insert hyper links.

43. What is the use of ARRAY command in AutoCAD?

Answer: It is used to creates copies of objects arranged in a pattern. Moreover we can create
copies of objects in a regularly spaced rectangular, polar, or path array.

44. What is the difference between REDO and MREDO command in AutoCAD?
Answer: The REDO command reverses the total action of the last UNDO command. In
contrast, MREDO (multiple redo) allows you to select how many of the commands, in reverse
chronological order, you want to redo.

Options.. from the bottom of the shortcut menu, or selecting Options.. from the bottom of
Application Menu.
Step 2 : In the Plot and Publish tab, locate the Default plot settings for new drawings
cluster near the top-left corner of the dialog box. Select the desired plot device from the list
(such as a laser printer), then select the Use as default output device button.
Step 3 : Select OK.

46. From which options you can freeze a AutoCAD layer?

Answer: Layer Property Manager.

47. How can you apply the same properties of an object to another object in AutoCAD?
Answer: Using Match Properties. (Matchprop)

48. Which AutoCAD command helps you to transfer selected objects from Paper Space
to another?
Answer: Chspace command.

49. What are the guidelines for plotting layouts to scale? Assuming that you are using
one viewport that fills all of the printable area.?
Answer:
These are the steps to be followed when plotting layouts to scale.
1. Set Units ( Decimal, Architectural, Engineering, etc) and Precision to be used in the
drawing.
2. Set model space Limits and create the geometry in model space. Use the DSF to
determine values for line type scale, text size, dimension scale, hatch scale, etc. Complete the
drawing geometry in model space.
3. Activate a layout to begin setting up the layout. You can also use the Layouts Wizard to
create a new layout and complete steps 2 through 5.
4. Use Page Setup to select the desired Plot Device and Paper Size.
5. Create, Insert, or Xref the title block and border in the layout. If you are using one of
AutoCAD's template drawings or another template, the title block and border may already
exist.
6. Create a viewport using Vports.
7. Click inside the viewport to set the viewport scale. You can set the scale using the
Viewport Scale pop-up list, Viewports toolbar, the Properties palette, or use Zoom and
enter an XP factor. Use 1/DSF as the viewport scale.
8. Activate the Plot dialog box and ensure the scale in the Scale drop-down list is 1:1. Make
a plot Preview, then make the plot or make the needed adjustments.

50. What is the use of Partialopen command in AutoCAD?

Answer: It helps to speeds up and simplifies loading, viewing, and working with large
drawings. With Partialopen you can select which views and layers, and therefore which
geometry, you want to load. This feature frees up system memory, speeds up regeneration,
and prevents having to view and manipulate unneeded layers and geometry.

51. What is the use of Overkill command in AutoCAD?

Answer: Overkill automatically removes duplicate or overlapping lines, arcs, and poly lines.
In addition, if partially overlapping or contiguous lines, arcs, and poly lines are selected, they
will be combined to become one object.
