Like Library objects, drawn 2D and 3D objects may now be inserted from any of their corners, or other logical points. For example, a Riser may be inserted from the centre of its bottom surface, instead of only its bottom left corner. To select a different insertion point, simply right-click before placing the object.
Change 2D & 3D Primitives’ Insertion Points
In addition, such Objects’ Insertion Points may be changed after they’ve been inserted with a single valid object selected, right-click to select a new point from which to move, rotate or scale it.
