Issue:

In CAD software, many functions prompt the user to "select objects", such as move and copy. In addition to using the cursor to click or drag a selection box around objects, are there any other ways or techniques to make selections?

Solution:

When it prompts "select objects:", user can enter "?" to learn about the specific use of the method.

In addition to the direct selection methods that the cursor can provide (such as clicking, window selection, and crossing), there are several other options that are frequently used in drawing:
Last (L): Select the last selected object.
All (ALL): Select all objects, except those in the locked layer.
Previous (P): Select the previously created selection set.
Fence (F): Select all objects that intersect the selection box.


WPolygon (WP): selects all objects within the defined polygon area.

CPolygon (CP): selects all objects inside or intersecting the polygon defined by the specified point.
