A simple selection

To make a simple selection, click on any object in a drawing and it will be highlighted, indicating that it is selected. To include multiple objects in this selection set, simply click on more objects and they will be added to your selection set.

If you want to disable the multiple selection feature, you can use the PICKADD system variable. Type PICKADD then press Enter and then type 0 and press Enter again.

Now, AutoCAD will allow you to make only one selection at a time. If you select another object, the previously selected one will be removed from the selection. To add multiple objects to the selection in this condition, you need to press and hold the Shift key and then click on the objects to add them to the selection set.

If you have added multiple objects to your selection and you want to remove some of them, press and hold the Shift key and click on the selected object again and it will be removed from the selection set.

For this book, we will keep the PICKADD system variable value to 2, so type PICKADD and press Enter. Type 2 and press Enter again to change the settings to the default.
