Removing Calculation Points

This command allows you to remove individual calculation points from a calculation (grid, surface, scattered, lines, polygon, object). Removed points are no longer considered in the calculations. Removed points can be replaced back into the calculation at any time and calculated. When removing points using the Polygon or Under Entities option, all points inside the boundary are removed.

Remove points using a polygon

The polygon option is used to remove points within a user-defined boundary. During specification of the polygon, it is possible to undo the polygon vertexes by selected the Undo button on the main toolbar or by pressing Ctrl-Z.

From the Modify menu choose Calculations -Remove Points-Polygon, or from the Calculations toolbar select $image\calc_button-remove_points.jpg$ .
Locate the first vertex of the polygon and click the left mouse button.
Drag the cursor to locate the second vertex of the polygon and click the left mouse button.
Continue until all of the vertices have been specified.
Right click the mouse or press [ENTER] on the keyboard to close the polygon and remove the points within.

Remove points using a window

The window option is used to remove points bounded by a user-defined rectangle.

From the Modify menu choose Calculations - Remove Points - Window, or from the Calculations Toolkit, click on the down-arrow next to this button $image\calc_button-remove_points.jpg$ to invoke the secondary menu. Select Window.
Locate the first corner of the window and click the left mouse button.
Drag the cursor to the opposite window corner and click the left mouse button. The points within the window will be removed.

Remove single points

From the Modify menu choose Calculations - Remove Points - Single, or from the Calculations Toolkit, click on the down-arrow next to this button $image\calc_button-remove_points.jpg$ . to invoke the secondary menu. Select Single.
With the left mouse button, click on the desired calculation point (the dot) or its associated value (or ? if not yet calculated).
Continue selecting points in this fashion, if desired.
Right click with the mouse or press [ENTER] on the keyboard to confirm your selections and remove the selected points.

Remove points under entities

This option is used to remove points within the X-Y projected area of a user- selected entity or entities. (Rooms and Objects only.) Calculation points are removed within or under the entity projected footprint (in Plan View) regardless of their own or the entity’s Z coordinates.

From the Modify menu choose Calculations - Remove Points - Under Entities (Single, Window or All), or from the Calculations Toolkit select $image\calc_button-remove_points.jpg$ . Left click on the pull-down arrow to the right of the button to invoke the secondary menu. Select Under Entities – Single, Window or All.
Select the entity(ties) that contains the points you wish to remove. (Rooms and Objects only.)
If the Single option was selected, you may continue selecting entities that contain calculation points you wish to remove.
Right click the mouse or press [ENTER] on the keyboard to confirm your selections and remove the points within.
