Tip of the Week #59 - Freehand (Lasso) Selection

Blog Post created by Matt McLean on Oct 8, 2018

Come one, come all! Tip of the Week time is upon us. This weeks Tip is on a little known selection method that is shared with Trimble Realworks, the Freehand (or Lasso) Select!

 

We all know of the Rectangle Select, perhaps also the Polygon Select, they have their own icons in the quick access toolbar and keyboard shortcuts after all. This week’s tip sheds some light on a selection method users have a love/hate relationship with, the Freehand Select!

 

To use the Freehand Select, begin by choosing Polygon Select from the Quick Access Toolbar.

 

Once in Polygon Select mode, the Freehand Select can be started in 3 easy steps:

  1. Click and hold the left mouse button then press and hold the Alt key.
  2. Move the cursor slightly.
  3. Release the left mouse button then release the Alt key.

 

Again, those steps are:

Left click and hold, Press Alt and hold.

 

Move the cursor slightly, release the left mouse button, release the alt key.

And voila! Freehand selection.

 

Now you can move your mouse and draw a line with which to select objects in Plan View or 3D View. When you are done drawing a selection area, double click to make the selection, just like with Polygon Select.

 

Again just like Polygon Select, drawing the selection clockwise will select only objects completely contained in the selection, and drawing counter-clockwise will select all objects which are partially contained in the selection area.

 

By doing this I have easily cropped this tree from the point cloud! I have the point cloud colored by elevation here.
