AutoCAD offers many ways to select geometry (Selection Sets) the latest selection option added offers quick selection using just the mouse. Whether you are at a Select Object prompt or are pre-selecting geometry on the screen this option is available. See a previous Blog titled “Select items on the screen, Let us count the ways,” for additional selection sets options.
Lasso: How this works:
When the program prompts you to Select objects or if you are pre-selecting items this feature is available.
With the mouse Pick (select) a point on the screen, DO NOT take your finger off of the pick button of the mouse, move the mouse through and around the items you want included in the selection. This creates an irregular shaped selection area.
Lasso selection features:
Window Lasso: Select a point on the screen move the mouse to the RIGHT of that
selection, this creates an irregular shaped area dawn around the geometry intended for the selection. The visual results on the screen is a solid outer line with the interior of the shape blue in color. This selection responds like the Implied Window selection, everything completely contained inside the solid lines will be selected.
Fence Lasso: This option becomes available when a Lasso selection is active on the
screen and the mouse button is still held, select the Spacebar. By selecting the Spacebar it cycles you through the Window, Fence and Crossing Selection features without reselecting the geometry. The Spacebar turn the outer line into a Fence, all the geometry that the line touches is selected.
When cycling though the options and the one you want is visible on the screen let go of the mouse button the selection stays current and allow you to continue.
Crossing Lasso: Select a point on the screen move the mouse to the LEFT of that
selection. This creates an irregular shaped area drawn around the intended geometry. The visual results on the screen is a dashed outer line with the interior of the shape green in color. This selection responds like a Crossing Window or Crossing Polygon selection, everything completely contained inside and everything the dashed lines touch will be selected.
*Watch the Command line it shows the prompts to cycle through the selection options by selecting the Spacebar.
*The Geometry Highlights to represent what is being selected.
