This tool splits an edge into two, with existing applicable constraints being copied to the new edge. The position of the point where the edges meet is not constrained. Periodic curves (i.e. circles, ellipses and periodic B-splines) are converted to non-periodic curves (respectively arcs of circles, arcs of ellipses and non-periodic B-splines).
The [[Image:Sketcher_Split.svg|24px]] [[Sketcher_Split|Sketcher Split]] tool splits an edge. If the edge is a closed curve (i.e. a circle, an ellipse or a periodic B-spline) it is converted to an open curve (an arc, an arc of ellipse or a non-periodic B-spline respectively).

Description

The Sketcher Split tool splits an edge. If the edge is a closed curve (i.e. a circle, an ellipse or a periodic B-spline) it is converted to an open curve (an arc, an arc of ellipse or a non-periodic B-spline respectively).

Usage

See also: Drawing aids.

  1. There are several ways to invoke the tool:
    • Press the Split edge button.
    • Select the Sketcher → Sketcher geometries → Split edge option from the menu.
    • Use the keyboard shortcut: G then Z.
  2. If there is a previous selection it is cleared. The tool does not accept a pre-selection.
  3. The cursor changes to a white cross with the tool icon.
  4. Click an edge at the point where it should be split.
  5. If the original edge is a line or an open curve, two new edges are created connected by a Coincident constraint. For closed curves a new open curve is created, the new point then does not receive a Coincident constraint. Existing applicable constraints are transferred to the new edge(s). See Notes.
  6. This tool always runs in continue mode: optionally keep splitting edges.
  7. To finish, click in an empty area in the 3D view, right-click or press Esc, or start another geometry or constraint creation tool.

Notes

  • A Coincident constraint is applied to the center points of new arcs.
  • Radius and Diameter constraints are copied to new arcs (resulting in a redundancy).
  • Coincident constraints and Point onto object constraints are transferred to the closest new edge.
  • Horizontal and Vertical constraints between points are transferred to the closest new edge.
  • Horizontal and Vertical edge constraints are copied to new line segments.
  • Parallel and Perpendicular constraints are copied to new line segments, for new arcs they are only copied to the closest.
  • Distance constraints are transferred to the closest new edge.
  • Angle, Symmetry and Block constraints are currently not transferred.
