Direct distance entry in AutoCAD - Cell-by-Cell Formula Trace

Sample Data

Coordinates and parameters for drawing a line using direct distance entry in AutoCAD.

Cell	Value
A1	Start Point X
B1	Start Point Y
A2	0
B2	0
A3	Distance
B3	Angle (degrees)
A4	5
B4	45
A5	End Point X
B5	End Point Y

Formula Trace

End Point X = Start Point X + Distance * COS(Angle) End Point Y = Start Point Y + Distance * SIN(Angle)

Step 1: COS(45 degrees)

Step 2: SIN(45 degrees)

Step 3: Distance * COS(45 degrees) = 5 * 0.7071

Step 4: Distance * SIN(45 degrees) = 5 * 0.7071

Step 5: End Point X = Start Point X + 3.5355 = 0 + 3.5355

Step 6: End Point Y = Start Point Y + 3.5355 = 0 + 3.5355

    A       B
1 |Start X|Start Y|
2 |   0   |   0   |
3 |Distance| Angle |
4 |   5   |  45   |
5 | End X | End Y |
6 |       |       |

Cells A2 and B2 hold the start point coordinates. Cells A4 and B4 hold the distance and angle values used for direct distance entry.

Result

    A       B
1 |Start X|Start Y|
2 |   0   |   0   |
3 |Distance| Angle |
4 |   5   |  45   |
5 | 3.54  | 3.54  |

The end point coordinates calculated using direct distance entry are approximately (3.54, 3.54).

What is the main purpose of Direct distance entry in AutoCAD?

easy

A. To type exact lengths for drawing or moving objects

B. To change the color of objects quickly

C. To save files automatically

D. To zoom in and out of the drawing

Solution

1. Step 1: Understand the feature's function

   Direct distance entry allows users to input exact lengths when drawing or moving objects.

2. Step 2: Compare options to the feature's purpose

   Only To type exact lengths for drawing or moving objects describes typing exact lengths, which matches the feature's purpose.

3. Final Answer:

   To type exact lengths for drawing or moving objects -> Option A

4. Quick Check:

   Direct distance entry = exact length input [OK]

Hint: Think: direct typing of length for precision [OK]

Common Mistakes:

• Confusing with color or zoom commands
• Thinking it saves files automatically
• Assuming it changes object properties

2.

Which of the following is the correct way to use direct distance entry when drawing a line in AutoCAD?

easy

A. Type length, move cursor in direction, then click

B. Click first, then type length and direction

C. Move cursor, type length, then click

D. Type direction, then length, then click

Solution

1. Step 1: Recall direct distance entry steps

   You first move the cursor to set direction, then type the length, then click or press Enter to place the point.

2. Step 2: Match steps to options

   Move cursor, type length, then click matches this exact sequence.

3. Final Answer:

   Move cursor, type length, then click -> Option C

4. Quick Check:

   Direction first, then length, then click [OK]

Hint: Move cursor for direction before typing length [OK]

Common Mistakes:

• Typing length before moving cursor
• Clicking before typing length
• Moving cursor after clicking

3.

In AutoCAD, you start drawing a line from point (0,0). You move the cursor to the right and type 5 using direct distance entry, then press Enter. What will be the coordinates of the new point?

medium

A. (5, 0)

B. (0, 5)

C. (5, 5)

D. (0, 0)

Solution

1. Step 1: Understand direct distance entry from origin

   Starting at (0,0), moving cursor right means positive X direction.

2. Step 2: Apply typed distance

   Typing 5 means move 5 units along X axis, Y remains 0.

3. Final Answer:

   (5, 0) -> Option A

4. Quick Check:

   Right direction + 5 units = (5, 0) [OK]

Hint: Right movement changes X coordinate only [OK]

Common Mistakes:

• Swapping X and Y coordinates
• Assuming diagonal movement
• Not pressing Enter after typing distance

4.

You try to use direct distance entry by typing a length but nothing happens. What is the most likely reason?

medium

A. You forgot to move the cursor in the direction before typing

B. You typed the length but did not press Enter

C. You typed the length after clicking the point

D. You used the wrong units

Solution

1. Step 1: Identify the direct distance entry process

   After typing the length, pressing Enter confirms the input.

2. Step 2: Analyze why nothing happens

   If Enter is not pressed, AutoCAD does not accept the typed distance.

3. Final Answer:

   You typed the length but did not press Enter -> Option B

4. Quick Check:

   Press Enter after typing length [OK]

Hint: Always press Enter after typing distance [OK]

Common Mistakes:

• Ignoring the Enter key
• Moving cursor after typing but before Enter
• Assuming units cause no response

5.

You want to draw a line starting at (2,3) that is exactly 10 units long at a 45-degree angle using direct distance entry. Which sequence of actions will achieve this?

hard

A. Start line at (0,0), move cursor to 45°, type 10, press Enter

B. Start line at (2,3), type 10, move cursor to 45°, press Enter

C. Start line at (2,3), type 45, move cursor to 10°, press Enter

D. Start line at (2,3), move cursor to 45°, type 10, press Enter

Solution

1. Step 1: Set starting point and direction

   Begin drawing line at (2,3), move cursor to 45° angle to set direction.

2. Step 2: Enter length and confirm

   Type 10 for length, then press Enter to confirm the distance along 45°.

3. Final Answer:

   Start line at (2,3), move cursor to 45°, type 10, press Enter -> Option D

4. Quick Check:

   Direction first, then length, then Enter [OK]

Hint: Move cursor to angle before typing length [OK]

Common Mistakes:

• Typing length before moving cursor to angle
• Starting at wrong point
• Confusing angle and length inputs
