The toolbar

In the point editing window (the bottom window), there is a set of buttons that allow various actions to be performed on the point list. Let's go over each of these actions.

Reorder in columns

Clicking this button will arrange the coordinate list into columns according to:

```

NAME     X     Y     Z     CODE

```

where each column is left-aligned.

(Note: X refers to the geometric Easting.)

Note: This action assumes the coordinate list is valid. If you click this button when the list is not valid, the invalid rows might change unexpectedly.

Save as file

You can save the entire point list or a part of it as a text file.

Clicking this button will bring up a save as text file dialog box, where the user is prompted to select a directory and enter a file name. The software will create a new file with the entered name and save the coordinates in it as a clean ASCII file. The ASCII file will be saved exactly as it appears in the coordinate list (including empty lines or comments, if any).

You can save the coordinate file in different formats. To do this, use the following option: in the save as text file dialog box, there is a Filter line with the text: All files (*.*). Click the small arrow button to the left and select the desired format (Med, Reg, etc.). From that moment, if you command to save a text file, it will be saved with the chosen extension and format.

Note: This action supports working with blocks, so you can save only part of the list by selecting coordinates as a block.

Load from text file

After clicking this button, a load from text file dialog box will appear where you will be prompted to choose the file name you want to load. The file will be loaded and will appear in the coordinate list. Note that the current point list, if one exists, will not be deleted, and the file data will be appended to this list. This way, you can combine several files and expand measurement areas. If you want the list you are loading to overwrite the existing list, you must first click the "Erase All Coordinates" button and then load the new list.

Print

Activating the button will create a print dialog box. Ensure the printer is connected and ready to print, and click "OK" to print the point list.

Note: This action supports working with blocks, so you can print only part of the list.

Erase All

This action will delete all coordinates in the list. Before deletion, a warning will appear:

All coordinates will be erased!

Click "OK" to proceed with the deletion.

Note: This action is not supported by the Undo function, so the list cannot be restored.

Erase

This button is used to delete a single point or a block of points. Select a point with the mouse (within the list) and click the button. The point will be deleted from the list.

Note: This action supports working with blocks.

Copy

This command, in conjunction with the Paste command, is used to copy coordinates. You can copy a single point or a block of points.

Paste

This command completes the previous Copy action and is used to paste coordinates. Assuming you used the Copy command to copy a specific block (or a single row) to memory, you can duplicate it (paste it) anywhere within the point list.

After copying the point(s), click the Paste button. You will notice that the points copied to memory will be pasted at the row you are currently at. To distinguish these points from the existing ones, a C will be added before each point.

Note: You can similarly copy a group of points from the current state Topography Coordinates list to the planned state Designed Coordinates list.

Find

This action allows you to locate a point or points in the list by name, height, or code. Clicking the command button will bring up the find dialog box:

To locate a point by name:

In the "Find what" menu, set the search mode to Name.

Enter the name you want to locate and press Enter or OK.

Advanced search options:

To search for multiple names, enter, for example: 1000,1002,2003

To search within a certain range, enter, for example: 1000-1004

You can perform a combined search, for example: 10,50,60-40

The order of entering parameters in the search box does not matter. The point will be found, highlighted in blue, and appear in the point editing row.

Pressing Enter again will search for the next point in the list with the same name (if there is one), and so on. To have the software directly mark all search results in the list, click on "Find All."

To locate a point by height:

We have seen the use of locating points by name. Similarly, you can locate points by their height:

In the "Find what" menu, change the search mode from Name to Height.

Enter the height you want to locate and press Enter or OK.

Advanced search options:

- To search for heights above a certain value, change the SearchMode to At Least

- To search for heights below a certain value, change the SearchMode to At Most

- You can also perform advanced searches using the methods mentioned in name search.

For example, to search for points between heights 234 and 235, select: Accurate, ALL, Height.

To locate a point by code:

In the "Find what" menu, set the search mode to Code.

Enter the code you want to locate and press Enter or OK.

Insert a blank row

Clicking this button will insert a blank row before the highlighted row. To perform this, select the row before which you want to insert a blank row and click the button.

Mark all

This button marks the entire point list, including empty rows and comments. This way, you can more easily select the entire list to work on a block that includes all points.

Options

These options allow control over the type and size of the point text displayed on the screen. Clicking the button will open the main options window. In the lower right corner of this window, you will find the options related to the coordinate list. Let's go through and detail the possible actions in this window:

Standard mode – Coordinate display using texts:

- Names – Display of point names. If this option is selected, the point name will appear next to the point.

- Elevations – Display of the point's elevation.

- Codes – Display of the point's code. This refers to the display of the text code.

- Circles – Display a circle around the point.

- Crosses – Display a cross on the point.

- Barracks – Display brackets around the point's elevation. You can choose several types of brackets or cancel the bracket display entirely (None).

- Scale – Choose the text size. The font size distribution by scale is as follows:

 - Up to 1:100 font size: 0.1

 - Up to 1:250 font size: 0.5

 - Up to 1:500 font size: 0.7

 - Up to 1:1000 font size: 1.2

 - Up to 1:1250 font size: 1.5

 - Up to 1:5000 font size: 5

 - Up to 1:10000 font size: 10

- Format – The format in which the points are displayed. There are two formats for displaying points (besides Blocks).

 - Format 1 – The point elevation will appear beside the point itself - meters to the left of the point and centimeters to the right.

 - Format 2 – The point elevation will appear above it.

 - Millimeter – Display the elevation up to 3 digits after the decimal point (in millimeters).

Blocks mode – Coordinate display using blocks:

After selecting this option, all point components (elevation, name, and marker) will appear unified in one block, displayed according to the defined block library and the coordinate's code number. See more in the chapter - Working with Codes.

To apply and save changes, click OK and then the Refresh button. Clicking Cancel will discard any changes.

Auto freeze

You can set CivilCAD to automatically mark and freeze outlier coordinates (with unusual height or distance) and alert the user.

In the Options screen, check the Auto freeze exceptional points option and click OK, then click the Refresh button. In the message window that appears, click OK. Coordinates that are out of the measurement range or have an unusual height will be automatically frozen and will not be calculated in the interpolation construction.

Sort

This action allows sorting the point list by their numbers in ascending order. Clicking the button will display the message: "All coordinates will be sorted." Click OK to perform the action. The point list will be sorted in ascending order by point numbers. All points with alphanumeric names will be moved to the beginning of the list.

Note: The sorting action is not supported by the undo function.

Auto Numbers

This action allows automatic renaming of points. After clicking this button, a window will open allowing the following settings:

- Start column – The position of the first character in the new point name.

- End column – The position of the last character in the new point name (the software will not go beyond this position).

- Start counting from – The value to start numbering from.

After clicking OK, the software will display a confirmation window, and upon confirmation, it will change all the point names in the list. If part of the list is selected by Block, the changes will be applied only to that part.

Freeze

This action allows you to exclude a point from the calculation. A frozen point will appear on the drawing but will not be included in the creation of contour lines. In this way, you can freeze manholes, inlets, and more.

To freeze a point, select it from the list and click the button. The symbol <Fr> will appear to the left of the point. Continue selecting the other points you want to freeze. Then refresh the drawing - the frozen points will appear on the drawing. You must recalculate the contour lines - then you will see the change according to the point freeze. To unfreeze a point, select it and click the freeze button again.

Note: You can also freeze measurement points by adding the code Fr to the desired point.

Locate Point on Drawing (Zoom to point on drawing)

This function allows you to locate a point on the drawing from the list. Select the point (in the list) you want to locate and click the button.

Compute Height

This function enables the calculation of a point's height through interpolation based on its coordinates. The height calculation will only be performed if contour lines are present on the drawing.

For example, suppose you have a project with contour lines and you want to find the height of a point whose coordinates are known.

1. Add the new point to the coordinate list.

2. Select the point in the list using the mouse.

3. Click the button.

You will notice that a height has been calculated for this point. If you have a design, you can calculate the planned heights of desired points from the planned topography by performing this action on the planned point list.

This function supports block operations.

Add/Reduce Height (Add height)

This function allows you to add or reduce the height of a block or all points.

1. To activate, click the button.

2. In the box that opens, enter the desired height adjustment. To reduce height, enter a negative value (preceded by a minus sign).

3. Click OK to perform the action or Cancel to cancel it.

Note: To add/reduce height for only a subset of points, first select these points and set them as a block.

Save Position of Name and Height Data of Coordinates Defined Graphically by the User

Saving will be done in Standard Mode and in Format 2 only.

1. Click the Options button.

2. Select the Standard Mode option and choose Format 2.

3. Click the OK button to save the settings.

4. The 'Save Coordinates Text According To Definitions' button in the Topography Coordinates menu will become active.

5. After changing the position of the height and name data of the coordinates, click this button to save the settings.

In the Design → Coordinates / Topography → Coordinates table, columns for the name and height coordinates according to their new positions will be added on the right.

Note: For coordinates that were not changed, the data on the right and left will be identical.

Update Block Rotation – Scan Blocks

This function scans blocks from the drawing and calculates the rotation angle for the coordinate list.

After clicking the Update block's rotation button, the software will scan the blocks in the drawing and match them to the coordinate list. A point that matches (in terms of location) the block location in the drawing will be updated with the corresponding rotation angle. Ensure that the block's rotation in the drawing is done around the insertion point.

Swap Coordinate Axes

This button swaps the X and Y coordinates in the point list (Topography Coordinates).

To see the effect of this action on the drawing, click the Refresh button. In ACAD, click Zoom → Extents to move to the new drawing area.
