PointList
2D/3D

• PointList is an option for Body that is used to specify a list of local point coordinates on a body.
• PointList->{{x1, y1}, {x2, y2}, ... , {xn, yn}} (2D) or PointList->{{x1, y1, z1}, ... , {xn, yn, zn}} (3D) specifies n points on the body that are referenced by their point numbers 1 through n.
• PointList[bnum, lpnt] returns the local coordinates of point lpnt on body bnum.
• PointList[bnum] returns a list of all the point coordinates on body bnum.

• If no points are specified for a body, no default values are set for the points; unspecified points are not set to zero.
• The specified list replaces any points that are currently defined on the body. Thus PointList->{} removes all points currently on the body.
• Referencing a point number of a point that has not been specified generates an error.
• The default setting PointList->Automatic leaves the current points table unchanged.
