Modifying points in AutoCAD Civil 3D involves editing various properties and attributes such as location, elevation, description, and style. Here’s a step-by-step guide on how to modify points:
1. *Selecting Points to Modify*
1. **Open Your Drawing**: Start AutoCAD Civil 3D and open the drawing that contains the points you want to modify.
2. **Select Points**:
- Use the selection tools to choose the points you want to modify. You can select points individually by clicking on them or use a selection window to select multiple points at once.
- Alternatively, use the Prospector tab in the Toolspace to navigate to your point group and select points from there.
2. *Modifying Point Properties*
#### A. *Using the Properties Palette*
1. **Open Properties Palette**:
- Select the points you want to modify.
- Press `Ctrl + 1` to open the Properties palette.
2. **Edit Properties**:
- In the Properties palette, you can modify various attributes of the selected points, such as:
- **Position**: Change the coordinates (X, Y, Z).
- **Elevation**: Adjust the elevation value.
- **Description**: Update the point description.
- **Point Style**: Change the visual style of the points.
- **Point Label Style**: Change the labeling style of the points.
3. **Apply Changes**:
- After making the necessary modifications, press `Enter` or click elsewhere in the drawing to apply the changes.
#### B. *Using the Point Editor*
1. **Open Point Editor**:
- In the Toolspace, go to the Prospector tab.
- Expand the "Points" collection and right-click on the point group containing the points you want to modify.
- Select "Edit Points" to open the Point Editor.
2. **Modify Point Data**:
- In the Point Editor, you can edit the properties of points in a tabular format.
- Update fields such as Northing, Easting, Elevation, Raw Description, Full Description, and Point Style.
3. **Save Changes**:
- After making the changes, close the Point Editor. The modifications will be applied to the points in your drawing.
3. *Using Grips for Quick Modifications*
1. **Select Points with Grips**:
- Click on a point to activate its grips. Grips appear as small squares at the point’s location.
2. **Move Point**:
- Click on the grip and drag the point to a new location. Release the mouse button to place the point at the new location.
3. **Change Elevation**:
- If you need to change the elevation, select the point and use the properties palette or Point Editor to modify the Z-coordinate.
4. *Modifying Point Styles and Labels*
1. **Change Point Style**:
- Select the points you want to modify.
- Right-click and choose "Point Group Properties".
- In the Point Group Properties dialog box, go to the "Information" tab and select a new "Point Style".
2. **Change Point Label Style**:
- In the same dialog box, go to the "Label Style" tab and choose a new "Point Label Style".
5. *Modifying Points with Commands*
1. **Using the `EditPoints` Command**:
- Type `EditPoints` in the command line and press `Enter`.
- This command opens the Point Editor, allowing you to make batch modifications.
2. **Using the `MOVE` Command**:
- Type `MOVE` in the command line and press `Enter`.
- Select the points you want to move and specify the base point and the new location.
