### Entering Degree Symbols in AutoCAD
To insert the degree symbol in AutoCAD, you can utilize multiple methods. One of the simplest ways is to use the MTEXT feature. By typing `%%D`, the degree symbol will be automatically inserted. For other applications such as Microsoft Word and Excel, hold down the `Alt` key and type `248` on your number pad to achieve the same result.
### Inputting Degrees and Minutes in AutoCAD
For entering degrees and minutes, you might find it useful to watch instructional videos, as visual demonstrations can clarify the process effectively.
### Drawing a 45-Degree Angle in AutoCAD
1. Launch AutoCAD and open a new or existing drawing.
2. Activate the Line command by typing ‘L’ and pressing ‘Enter.’
3. Specify the initial point by clicking on the drawing area.
4. Move in the desired direction and type the length of your line (e.g., `100` units).
5. To specify the angle, press the `Tab` key or type `@` followed by your angle.
6. Input `45` for the angle, then hit `Enter` or press the `Spacebar`.
7. Your 45-degree angle line is now created.
### Drawing a 90-Degree Line in AutoCAD
To construct a line at a precise 90-degree angle, follow these steps:
1. Open AutoCAD and ensure your workspace is ready.
2. Press `F8` to activate Ortho Mode, which restricts movement to horizontal or vertical directions.
3. Start the Line command by typing ‘L’ and pressing ‘Enter.’
4. Click to define the starting point.
5. Move in either a vertical or horizontal direction and click again.
6. Your 90-degree line should now be established.
### Creating North as 0 Degrees in AutoCAD
To configure North as the 0-degree reference in AutoCAD:
1. Enter the command `_UNITS` and press `Enter`.
2. Navigate to the Direction section and select the option to configure North as 0 degrees.
3. Confirm your selection and exit the dialog box. Your orientation is now set.
### Entering Geographic Coordinates in AutoCAD
To incorporate geographic coordinates:
1. Click on the Geolocation tab, then select the Edit Location drop-down and choose “From Map.”
2. In the Geographic Location dialog, follow the prompts by clicking Next.
3. From the list, select your desired GIS Coordinate System and click Continue.
4. Press `Enter` to complete the command sequence.
### Overview of AutoCAD Commands
Familiarizing yourself with commands in AutoCAD can enhance your efficiency. Here are some key commands:
– **L** (Line): Creates a straightforward line.
– **MI** (Mirror): Produces a mirrored copy of a selected object.
– **MLINE**: Allows for the creation of multiple, parallel lines.
– **PL** (Polyline): Draws connected line segments.
### Understanding Angle Measurements
A 45-degree angle is generated by bisecting a right angle (90 degrees), meaning that each half measures 45 degrees.
To construct a 90-degree angle with a 45-degree angle bisector:
1. Draw a straight line to establish a baseline.
2. Use a compass set to a distance greater than half the baseline to mark arcs above and below the line.
3. Connect the intersections to form a 90-degree angle.
### Drawing a 30-Degree Angle in AutoCAD
You can refer to visual tutorials to effectively create a 30-degree angle in AutoCAD.
### Comparison of Angles: 300 Degrees
The internal geometry of a circle means that a 300-degree angle corresponds to a 60-degree angle but the contexts of the two differ significantly.
### Drawing Straight Lines at 90 Degrees
Utilizing Ortho Mode (activated via the `F8` key) allows you to draw straight lines at 90-degree angles with ease.
### Drawing a 90-Degree Line
For detailed guidance on this process, video resources can often provide a clearer understanding.

### FAQs
**1. How can I make complex angles, like 75 degrees, in AutoCAD?**
To create a 75-degree angle, use the Line command and input the length and angle in the same manner as described for 45 degrees. Just replace the 45 with 75 in the angle input section.
**2. Is it possible to customize the degree symbol in AutoCAD settings?**
AutoCAD does not allow for customization of the degree symbol itself, but you can define it in annotations and ensure it appears correctly in your drawings when using MTEXT.
**3. What should I do if my angle measurements are not appearing correctly?**
Verify that your units and angle settings within AutoCAD are correctly configured. You can check these settings under the Units dialogue by entering `_UNITS` in the command line.
