3D-Origin-System

A visual model, which shows the view orientations and axes directions for 3D-models.The dimensions:datum planes: squares of 50 mmlength, measured over the arrow tips: approx. 85.25 mmA notice for PTC-users: the 3D-model has "saved views" with following definition:frt = front = vornebac = back = hintentop = top = obenbot = bottom = untensdr = side from right = rechtssdl = side from left = linksA recommended syntax for the datum planes, which overstretches each of the 6 views:[x-y] = front-[x-y] = back[x-z] = top-[x-z] = bottom[y-z] = side from right-[y-z] = side from leftFor rotating about the axes the "right hand rule" is a big help.The thumb points in direction of the arrow tip of the axis, and your fingertips point in the mathematically positive rotating direction (counterclockwise direction).Personally I prefer the "frt"-orientation of the 3D-model as the same orientation with the perpendicular view on the drawing sheet, which is hanging on a wall.Uploaded 3D-data:STEPPTC Creo Parametric 2.0I hope, that this model can show in an understanding way the view orientations and axes definitions for 3D-models. Espacially for newcomers, they want get starting of 3D-modeling, could it be a little help.Thank you for the attention of a little excursion, for defining a possible origin model, before starting in the world of 3D-modeling.Animation(s) and/ or suggestions for improvement of this model are always very welcome here.P.S.:The uploaded (.xls)-file can be used for printing out in 2D, cut out with scissors and fold it to a glued paper model (may be a puzzle work and/ or a challenge).Designations in the (.xls)-file:V = Vorne = FrontH = Hinten = BackO = Oben = TopU = Unten = BottomR = Rechts = RightL = Links = LeftThe directions of the three axes are also shown on each datum plane.
