Break Curve Dialog Box

The Break Curve dialog box appears when you click Break Curve in the Primary Area of the Edition section.

This dialog box contains controls for:

General



Report
Displays a status about cutting elements:

  • Cutting elements you can use for the break (marked by a green tip).

    When you click the text, the corresponding curve highlights in green.

  • Cutting elements that you cannot use for the break (marked by the condition to apply so that you can use them for a projection for example.)

    When you click the text, the corresponding curve highlights in red.

  • When a red cross appears, it means that the app cannot manage the problem.
  • When there is no selection of cutting elements, an error message appears and the Break Report dialog box informs you that no element is selected.

Selection

Elements
Defines the set of curves to be cut.
Limitation
Defines the set of limiting elements: points, curves, planes, or surfaces.
Notes:
  • You cannot break a multi-cell body using a cutting element at the cell boundary.

  • If you perform a trap selection in the model, all included elements will be selected. If no modifier is pressed, the current selection is emptied and only the included elements in the trap are selected. If Ctrl is pressed while creating the trap, the included elements are added to the current selection.

    In case of selection by trap, only valid elements are selected in the Elements and Limitation boxes.

Fragment
Breaks the curves by its segment boundaries in UV directions.
Break into equal number
Breaks a curve by an equal number, regardless of segmentation.
Number
Defines the number of equal parts in which the curve will be broken.
Invert Selection
Swaps the content selected in the Elements and Limitation boxes.
Break Both
Breaks elements to be cut and limiting elements by each other.
Disassemble Result
Disassembles the resultant multi-cell/domain bodies into mono-cell bodies.

Trim Type

Edge Trim
Relimits curves topologically and keeps the control points of the initial curves.
Curve Trim
Relimits curves geometrically and keeps the control points of the resulting curves.
Order
Not relevant for break curve.

Projection

Along Robot
Projects the curve along the Robot direction.
Along Normal
Projects the curve along the normal direction.
Along Viewing Direction
Projects the curve along the viewing direction.

Extrapolation

The following extrapolation options are available:

Tangential Extrapolation
Extrapolates curve (cutting element or element to be cut) along the tangent direction.
Curvature Extrapolation
Extrapolates curve (cutting element or element to be cut) along the curvature direction.
Parametric Extrapolation
Extrapolates curve (cutting element or element to be cut) along the parametric direction.

Notes:
  • If there is an intersection between the cutting element and the element to be cut, the extrapolation options even if available, do not have any effect.
  • Using the Break Both option:
    • You can extrapolate the element to be cut.
    • The vertex of the cutting element closest to the element to be cut is used to extrapolate the cutting element, and vice versa.
  • If a proper result is not obtained with this vertex, the vertex at the other end of the respective element is used for extrapolation purpose.
  • In case of multi-domain cutting element, domain that has the closest vertex to the element to be cut is used for extrapolation.

Deviation

Deviation Mode
Defines whether the deviation is displayed or not.
Max Deviation
Displays the maximal deviation between original and resultant surface in the dialog box and on the geometry.
Edge Deviation
Displays the deviation on edge.
