AutoCAD 2011 - Pickadd has changed
The system variable PICKADD has been changed for 2011. Most people probably will not notice, but I like it. Previously, there were 2 choices for this variable, 0 and 1. A setting of 2 was added. See the summary below.
- 0 - means that only your last selection is valid. In other words, if you select a entity, then select another entity, the first one becomes unselected.
- 1 - is what most people use. This allows you to continue to add entities to a selection set.
- 2 - works just like 1, expect that when using the ._Select command, the entities remain selected when the command is over. Previously when you used the ._Select command then executed a command, you had to use _P to refer to the previous selection set. Now you can use the ._Select command, create a selection and then launch the desired command with the selected objects pre-selected.
