Edit Calculations In A Polygon

The Edit Calculation Polygon dialog looks just like the original ‘Add’ calculation points dialog, with the addition of the specified polygon coordinates and the opportunity to respecify the polygon boundary. You may change the label, description, point spacing, text size, meter type, labeling and display options, and summary. In addition, you may edit each of the vertex's coordinates independently if desired.

If you have removed points from the polygon prior to editing, they will be replaced if you recreate the polygon (i.e. change point spacing, or respecify the polygon). Cosmetic changes, such as changing text color or text size, will not result in removed points being replaced.

Each line segment in the polygon will be identified by its line number, and its beginning X, Y and Z coordinates.

From the Modify menu choose Calculations - Edit, or from the Calculations toolbar select $image\calc_button-edit_points.jpg$ .
Select the calculation polygon by moving the pickbox cursor over it and clicking the left mouse button.
Make the desired changes.

To modify one or more of the line segments, click in the appropriate cell(s) and type in the new value(s).
To delete a line segment, click on the shaded cell to the left of the line number where the arrow is so that the entire row is highlighted, then press the [Delete] key on your keyboard. The selected segment will be permanently deleted.

You may respecify the entire polygon by clicking the Re-Specify Polygon button. Two modification choices are provided: Manually Specify Polygon and Create Polygon from Drawing Entity, Room or Object. Depending on which choice is selected, different steps will be required once you click the Re-Specify Polygon button. You will be returned to the graphics window where the existing polygon will be visible as a reference. Specify the polygon vertices as required and right click when the polygon is complete. At this time, any other changes that were specified in the Edit dialog before the Re-Specify Polygon button was clicked will also be applied. You will not be returned to the Edit Polygon dialog.

Follow the steps below depending on the selected Creation Method:

Specify a Polygon Manually	Create Polygon from Drawing Entity, Room or Object
Locate the first point of the polygon and click the left mouse button. Move the cursor to the second vertex on the polygon and left click again. Continue in this fashion until the polygon is complete. Right click to close the polygon shape. The Polygon grid will be created. To change the polygon elevation, move the cursor into the Z-Coord text box and enter a new value or use the up and down arrow keys on the keyboard, before clicking the first point. Locate the first point of the grid and click the left mouse button.	Locate the pickbox on the drawing entity line, object or room boundary you wish to use and left click. If a valid polygon is found (see Notes below), it will be displayed as a bold line, and the Polygon Search results dialog will appear: Accept Polygon and Repeat - Grayed out during this operation - can only respecify one polygon at a time. Accept Polygon - Create grid using selected entity as polygon boundary. Reselect Entities - Choose this option if invalid polygon was found or if incorrect line was chosen. Use pickbox to select another closed polygon. Manually Specify Polygon - Select vertices manually to specify polygon boundary, right clicking once all vertices are specified. This option is necessary if no valid polygon is found. Cancel - Do not create calculation entity. Notes: Drawing Entity line segments do not need to be joined, just need to be within tolerances (2 decimals of precision - .05) Line segments do not need to make a closed polygon - AGi32 will automatically close boundary line AGi32 filters related lines by color. Caveats: Disconnected line segments or line segments disconnected by gap larger than tolerance level will not form valid polygon. Polygons with intersecting lines will not form valid polygon. Incomplete polygons are not valid, may close in an unacceptable manner.

Specify a Polygon Manually

Create Polygon from Drawing Entity, Room or Object

Locate the first point of the polygon and click the left mouse button.
Move the cursor to the second vertex on the polygon and left click again.
Continue in this fashion until the polygon is complete. Right click to close the polygon shape. The Polygon grid will be created.
To change the polygon elevation, move the cursor into the Z-Coord text box and enter a new value or use the up and down arrow keys on the keyboard, before clicking the first point. Locate the first point of the grid and click the left mouse button.

Locate the pickbox on the drawing entity line, object or room boundary you wish to use and left click.
If a valid polygon is found (see Notes below), it will be displayed as a bold line, and the Polygon Search results dialog will appear:

Accept Polygon and Repeat - Grayed out during this operation - can only respecify one polygon at a time.
Accept Polygon - Create grid using selected entity as polygon boundary.
Reselect Entities - Choose this option if invalid polygon was found or if incorrect line was chosen. Use pickbox to select another closed polygon.
Manually Specify Polygon - Select vertices manually to specify polygon boundary, right clicking once all vertices are specified. This option is necessary if no valid polygon is found.
Cancel - Do not create calculation entity.

Notes:

Drawing Entity line segments do not need to be joined, just need to be within tolerances (2 decimals of precision - .05)
Line segments do not need to make a closed polygon - AGi32 will automatically close boundary line
AGi32 filters related lines by color.

Caveats:

Disconnected line segments or line segments disconnected by gap larger than tolerance level will not form valid polygon.
Polygons with intersecting lines will not form valid polygon.
Incomplete polygons are not valid, may close in an unacceptable manner.
