Point Selection

Some commands in Malz++Kassner CAD6 require a point selection, where the user selects a group of definition points that the current command shall be applied to. The point selection works similar for all commands. Any number of points can be chosen. This can be done with various methods, which can be used on their own or in combination with one another:

•	To select several points quickly, hold down the CTRL key and then click on each point. Release the CTRL key to end the selection.

•

Whole areas can be chosen by holding down the SHIFT key, and specifying either two opposite corners of a rectangle (by not holding SHIFT down for the second point) or multiple points of a polygon (by holding SHIFT hold for all points of the polygon and then releasing SHIFT). This chooses all the points which lie within the specified area. Alternately, you can use the Extra > Identify > Identify Area, Rectangle and Extra > Identify > Identify Area, Polygon commands.

•	If the same group of points is to be manipulated several times, it can be selected again by pressing the F11 Key.

•	To select all but the previously selected points, hold down the CTRL key and press F10 Key (select all) first, then F11 Key (previous selection).

At Options > Window, you can switch a highlighting on and off, which, when point selection is active, already shows which object's point would be selected from the current position while the crosshairs are being moved.

If several of these selection methods are to be combined, the CTRL key must be kept held down throughout the entire selection process. If you then release the CTRL key the current command will be carried out using the selected points.

All choosing operations are self-inverting, i.e. if a point is chosen twice during a choosing process, it counts as "not chosen". A third selection rechooses it, and so on.

If all points inside an area plus two additional points are to be chosen, follow these steps:
• Press and hold down the CTRL key
• Press and hold down the SHIFT key
• Enter the two corner points of the area
• Release the SHIFT key
• Click, one after another, on the two additional points
• Release the CTRL key

The point selection is influenced by the selection filter. To activate or deactivate the selection filter please choose the command Selection Filter (0) or click the corresponding button in the Panel. To edit the parameters of the selection filter please choose the command Selection Filter Parameters (+0). You can activate, deactivate, or edit the selection filter even during a point selection by keeping the CTRL key pressed until the point selection is completed.
