Tools - Selection
The "Selection" menu allows the user to apply certain functions to the workspace elements - most of these commands have a direct quick button on the main toolbar. These tools have the same effect as those in the editing panel.
Select All: selects all the currently active items in the workspace - triangles for meshes, points for clouds. The selected part will be highlighted by a red color.
Select None: Undo the previous selection of all the active items in the workspace.
Invert Selection: invert the previously done selection. The selected part will be highlighted by a red color.
Delete Selected Items: deletes those elements currently selected (highlighted in red) from the currently active object.
Manual Selection: allows to select points (for sparse clouds and dense clouds) or triangles (for mesh and textured mesh) through different selection modes (rectangle, polygon, ellipse, lasso, box). By choosing the desired mode and the desired elements in the 3D space, it will be possible to combine them using the appropriate action (add, remove and by using the pause button to freely move in the workspace). All the selected elements will be highlighted in red.
Select by Color: selects (on dense point clouds) all the points of a given color (within a given threshold).
Select by Plane: selects a part of the currently active subject - the selection is done by placing a plane that will "cut" the subject - all points above that plane will be selected. The selected part will be highlighted with a red color.
Select by Points: allows selection of a part of the currently active object in the workspace - the selection is made by including all the points contained within a dragged rectangle in the workspace (keeping the left-click button pressed) - when the click is released, the selection will be done. The selected part will be highlighted with a red color.
Select by Triangle: allows selection of a part of the currently active object in the workspace - the selection is made by including all the points contained withing a polygon defined by clicking and connecting the polygon points in the workspace - when the polygon is closed, the selected part will be highlighted by a red color.
Select Cameras: allows selections of the workspace cameras through different selection modes (rectangle, polygon, ellipse, lasso). Once selected, the cameras will be highlighted in orange both in the viewport and in the camera navigator.
New Object Via Copy: creates a new object in the workspace, by making a copy of the current selection.
New Object Via Cut: creates a new object in the workspace, by cutting the selected object. The inverse of the selection will become the origin object.
