Each key element (tolerance, softness, and patches) has a directional arrow that passes through its centre point. Use this
arrow to indicate the direction in which you want to perform a particular action, such as scaling or translating the element.
- To display an element's arrow, select the element by clicking on it.
- To set the arrow direction manually, click inside the key element anywhere between its centre and the area towards which you
want the arrow to point.
NoteYou can only click on a part of the element's surface that is visible. If necessary, rotate the RGB viewer so that the correct
area of the surface is visible.
- To point the arrow towards a plotted point, simply select the element (either by clicking on it or using the Picking box)
before plotting. The arrow will automatically point towards the plotted point.
- To reverse the direction of the arrow, click the Reverse Point button in the Key menu.
