Several options exist for deleting items. The first of which is the default button operation Delete Selected Items which is also triggered by pressing the Delete key on the keyboard.
As you select items to delete, either in the tree or graphic window, the selected items will highlight.
The distinction between Points and point groups is important here. Often times it is helpful to press delete and select a couple of points to delete. However, the purpose of this command is to select "Items" which translates to Point groups. SA has made a concession for this as follows:
If you select points one at a time in the graphics they will be selected individual.
If hold shift and select a region of points. The selection will be for point groups and all of the points contained within them will be selected.
Delete CAD Objects by Source offers an option imported objects as a unit. SA keeps track of the source of objects—whether they were created natively in SA or imported from CAD files. As a result, you can delete objects that were imported from a specific CAD file.
Delete Vectors provides a means to remove vectors from a Vector Group. This command only works for static vectors (not autovectors as the relationship will immediately rebuild deleted vectors). Vectors must also be selected graphically. To use this command select Delete Vectors then either pick the vectors in the graphical view one at a time or use Shift select to draw a region around the vectors for selection. You can either select the origin or the max extent point to select a vector.
Both delete Collections by Wildcard and delete Folders by Wildcard operations can be initiated under the Delete Items menu. These operations are helpful in tree management. For more details on wildcard selection refer to Wildcard under Navigation.
