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

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 on 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 constraints attached to lines 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.
Horizontal distance, Vertical distance and Distance constraints are transferred to the closest new edge.
Angle, Symmetric and Block constraints are currently not transferred.

-==Description==
+== Description == <!--T:3-->
-This tool allows to divide an edge into two identical ones, while most of the constraints are duplicated, so both parts remain constrained apart from split point position. For a special case of a circle, this is converted to an arc with loose ends with existing circle constraints being transferred to the new arc.
+<!--T:4-->
-[[File:SketcherSplitExample1.png]] [[File:SketcherSplitExample2.png]] [[File:SketcherSplitExample3.png]]
+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).
-==Usage==
+== Usage == <!--T:6-->
+<!--T:14-->
-# Press the {{Button|[[File:Sketcher_Split.svg|16px]] [[Sketcher_Split|Split]]}} button. The mouse pointer turns into a white cross with a red split symbol.
+See also: [[Sketcher_Workbench#Drawing_aids|Drawing aids]].
-# Click on the edge in the place where you want to split it.
-# From the line and arc edges, two new will be created, connected at the point clicked. A circle is converted to an arc with the very same center point and other constraints the original circle had.
-# Pressing {{KEY|Esc}} or pressing the right mouse button will terminate the function.
+<!--T:7-->
-==Limitations==
+# There are several ways to invoke the tool:
+#* Press the {{Button|[[Image:Sketcher_Split.svg|16px]] [[Sketcher_Split|Split edge]]}} button.
+#* Select the {{MenuCommand|Sketcher → Sketcher geometries → [[Image:Sketcher_Split.svg|16px]] Split edge}} option from the menu.
+#* Use the keyboard shortcut: {{KEY|G}} then {{KEY|Z}}.
+# If there is a previous selection it is cleared. The tool does not accept a pre-selection.
+# The cursor changes to a cross with the tool icon.
+# Click an edge at the point where it should be split.
+# If the original edge is a line or an open curve, two new edges are created connected by a [[Sketcher_ConstrainCoincident|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|Notes]].
+# This tool always runs in continue mode: optionally keep splitting edges.
+# To finish, click in an empty area in the [[3D_view|3D view]], right-click or press {{KEY|Esc}}, or start another geometry or constraint creation tool.

+* Horizontal and Vertical constraints attached to lines are copied to new line segments.
+* [[Sketcher_ConstrainParallel|Parallel]] and [[Sketcher_ConstrainPerpendicular|Perpendicular]] constraints are copied to new line segments, for new arcs they are only copied to the closest.

-* Vertical and horizontal constraints are copied to both offsprings.
-* Parallel and perpendicular constraints are copied for both line segments, for arc only once to the closer part.
