39 Plank Reference Volume (RV-PLANK)
RV-PLANK is composed of the following elements:
39.1 On the plane Z=0, a surface bounded by a five-sided simple polygon with vertices at the points:
a. [XF=430, 0]
b. [XF=430, 75]
c. [XF=690, 125]
d. [XR=-600, 125]
e. [XR=-600, 0]
39.2 Once the surface in §39.1 is fully defined, a fillet of radius 25mm must be applied at vertex (b) and a fillet of radius 2000mm must be applied at vertex (c).
39.3 Once the surface in §39.2 is fully defined it must be extruded along Z to Z=-10. 39.4 Once the volume in §39.3 is fully defined; a chamfer of 6mm x 150mm must be applied to the lower edge at XR=-600 and a chamfer of 6mm x 12mm must be applied to the remaining lower edges.
39.5 Once the surface in §39.4 is fully defined 50mm diameter holes must be cut through the volume parallel to the Z-axis, with centres at [XF=500, 0], [XF=1080, 75], and [-825 ≥ XR ≥ - 1025, 0]
39.6 The fully defined volume in §39.5 is RV-PLANK
