Selection Tools
Tip
With all selection tools (except Select Linked by Material), while holding the left mouse button and dragging in the viewport, hold Shift to add to the selection or hold Alt to remove/subtract from the selection.
Single Selection: select a single vertex per click (i.e. precision selection).
Lasso Selection (L)
Rectangle Selection
Ellipse Selection
Select Linked by Material: choose one of the mesh’s materials to select all vertices of the faces assigned to that material (just like Blender’s “Select Linked” feature).
This is only useful when the mesh has multiple materials.
Select All
Deselect / Clear Selection (Shift+L)
Invert Selection
