The Arrow design uses FilledTriangleArrowHead as one of its choices for the arrow at each end. FilledTriangleArrowHead can be a 'triangle' ,'filledTriangle', or a 'filledArrow'.
A dimension line is a thin line, broken in the middle to allow the placement of the dimension value, with an arrow at each end.

Parameter Rules
| faces: | An Array or list of faces. | 
| Example: | return [0,1,2] | 
| vertices: | Array of points to define the shape of the arrow head. | 
| Example: | const wt = R.world.transform; | 
| return [p(0,0,0,wt), | 
| p(-child.length,child.width/2.0,0,wt), | 
| p(-child.length,-child.width/2.0,0,wt)]; | 
| position: | A rule that defines a position in 3D space or paper space. | 
| Example: | return { origin: p(5, 2, 0, this.parent.transform ) }; |
