Issue:
At the Select Objects prompt in MicroSurvey, when you select an object to add to the selection set, previously-selected objects are removed from the selection set.
- Multiple objects can still be selected via selection or crossing windows, and by holding the SHIFT key while clicking the items.
- This occurs during all commands that prompt for selection as well: ERASE, COPY, TRIM, EXTEND, etc.
Causes:
The PICKADD system variable is set to a value of 0. This can happen if you inadvertently press the PICKADD toogle button that appears at the top of the Properties panel.Solution:
To allow selection of more than one object by clicking them with the mouse, set PICKADD to 1 or 2:
- At the command line, enter the PICKADD command.
- Enter 1 as the value.
More info:
PICKADD
Controls how entities are added to a selection set.
Can be set to one of the following values:
0 = PICKADD is turned off, the most recently selected entity becomes the selection set and previously selected entities are no longer part of the selection set.
1 = PICKADD is turned on. Each entity selected is added to the current selection set.
2 = PICKADD is turned on. Each entity selected is added to the current selection set. If the Select command is used, keeps entities selected after you stop using the command.
Default value = 2
