Operation Constructors

You can assign operating constructors using Business Process Knowledge Template app.
For more information on how to create functions and methods, see Business Process Knowledge Template User's Guide: About Knowledgeware Functions and Methods.
The functions are written in the Knowledgeware language. For more information on this language, see the Knowledge Advisor User's Guide.

Arguments
  • boundary (element: Surface): Curve
    Creates a boundary.
  • invert (CurveOrSurfaceToInvert: Wireframe): Wireframe
    Inverts the orientation of a curve or surface.
  • translate (totransform: Wireframe, dir: Direction, distance: Length): Wireframe
    Translates a point, curve, or surface.
  • symmetry (totransform: Wireframe, invariant: Wireframe): Wireframe
    Creates a symmetrical point, curve, or surface. The invariant must be of type Point, Line, or Plane. Otherwise, an error occurs.
  • rotate (totransform: Wireframe, axis: Line, angle: Angle): Wireframe
    Creates a rotated element.
  • scaling (totransform: Wireframe, reference: Wireframe, ratio: Real): Wireframe
    Creates a scaled element. The reference must be of type Point or Plane. Otherwise, an error occurs.
  • affinity (totransform: Wireframe, axisorigin: Point, 1stdirectionaxis: Line, ratioX: Real, ratioY: Real, ratioZ: Real): Wireframe
    Creates an affinity of an element.
  • assemble (Surface, ...): Surface
    Creates a join of several surfaces.
  • assemble (Curve,...):Curve
    Creates a join beween several curves.
  • disassemble (Input: surface, cellsMode: Boolean): List
    Disassembles a surface and creates a volatile list containing domains or cells of the surface.
    Returned list is volatile, as it contains temporary objects that are deleted at the end of the evaluation of the expression. Therefore, the Disassemble constructor is unsuitable to be used in rules or formulas. It should be used only in more complex expressions.
  • disassemble (Input: curve, cellsMode: Boolean): List
    Disassembles a wireframe and creates a volatile list containing domains or cells of the curve.
    Returned list is volatile, as it contains temporary objects that are deleted at the end of the evaluation of the expression. Therefore, the Disassemble constructor is unsuitable to be used in rules or formulas. It should be used only in more complex expressions.
  • split (tosplit: Curve, splitting: Wireframe, orientation: Boolean): Curve
    Enables you to split a surface.
  • split (tosplit: Surface, splitting: Surface, orientation: Boolean): Surface
    Creates a split of one surface by another. Use the third argument to choose the side to keep.
  • split (tosplit: Surface, splitting: Curve, orientation: Boolean): Surface
    Creates a split of one surface by a curve. Use the third argument to choose the side to keep.
  • trim (crv1: Curve, orientationCrv1: Boolean, crv2: Curve, orientationCrv2: Boolean): Curve
    Enables you to trim     two wireframe elements.
  • trim (sur1: Surface, orientationSur1: Boolean, sur2: Surface, orientationSur2: Boolean): Surface
    Creates a trim of one surface by another. Use the Booleans to choose the side to keep on each surface.
  • far (sur: Surface, far: Wireframe): Surface
    ‘sur’ is a non-connex surface.
    ‘far’ is a geometrical element.

    Among the connex sub-elements of ‘sur’, the far function returns the farthest from the ‘far’ geometrical element. The result is a surface.
  • far (crv: Curve, far: Wireframe): Curve
    ‘crv’ is a non-connex curve.
    ‘far’ is a geometrical element.

    Among the connex sub-elements of ‘crv’, the far function returns the farthest from the ‘far’ geometrical element. The result is a curve.
  • far (pt: Point, far: Wireframe): Point
    ‘pt’ is a non-connex point (for example, the full boundary of a line).
    ‘far’ is a geometrical element.

    Among the connex sub-elements of ‘pt’, the far function returns the farthest from the ‘far’ geometrical element. The result is a point.
  • near (sur: surface, near: wireframe): Surface
    ‘sur’ is a non-connex surface.
    ‘near’ is a geometrical element.
    Among the connex sub-elements of ‘sur’, the near function returns the nearest from the ‘near’ geometrical element. The result is a surface.
  • near (crv: Curve, near: Wireframe): Curve
    ‘crv’ is a non-connex curve.
    ‘near’ is a geometrical element.
    Among the connex sub-elements of ‘crv’, the near function returns the nearest from the ‘near’ geometrical element. The result is a curve.
  • near (pt: Point, near: Wireframe): Point
    ‘pt’ is a non-connex point (for example, the full boundary of a line).
    ‘near’ is a geometrical element.
    Among the connex sub-elements of ‘pt’, the near function returns the nearest from the ‘near’ geometrical element. The result is a point.
  • extract(cell : CATCell, propagationType: integer): Wireframe
    Function used to generate geometry from a sub element. The second argument is the propagation type as a G continuity (0: G0; 1: G1; 2: G2; 3: none).
    Return type can be any form of geometry, not just Wireframe. For instance, if the cell input is of dimension 2, the Extract feature will be a surface.
    Note: The cell input and the Datum feature to be valuated (the extract constructor’s output) should be in the same document.
     
Wireframe results returned by Invert command or transformation capabilities (such as Translate and Symmetry commands) cannot be affected to point, curve or surface variables. The <set x=y> syntax has to be used to valuate the result.
  For instance, use:

Set PartBody\Point.2 = translate(PartBody\Point.1 ,direction(`xy plane`),1mm) instead of PartBody\Point.2 = translate(PartBody\Point.1 ,direction(`xy plane`),1mm).
