.Modelica.Mechanics.MultiBody.Types.ShapeExtra .Modelica.Mechanics.MultiBody.Types.ShapeExtraThis type is used in shapes of visual objects to define extra data depending on the shape type. Usually, input variable extra is used as instance name:
| shapeType | Meaning of parameter extra |
|---|---|
| "cylinder" | if extra > 0, a black line is included in the cylinder to show the rotation of it. |
| "cone" | extra = diameter-left-side / diameter-right-side, i.e., extra = 1: cylinder extra = 0: "real" cone. |
| "pipe" | extra = outer-diameter / inner-diameter, i.e, extra = 1: cylinder that is completely hollow extra = 0: cylinder without a hole. |
| "gearwheel" | extra is the number of teeth of the (external) gear. If extra < 0, an internal gear is visualized with |extra| teeth. The axis of the gearwheel is along "lengthDirection", and usually: width = height = 2*radiusOfGearWheel. |
| "spring" | extra is the number of windings of the spring. Additionally, "height" is not the "height" but 2*coil-width. |
| external shape | extra = 0: Visualization from file is not scaled. extra = 1: Visualization from file is scaled with "length", "width" and "height" of the shape |
