Sketcher Geometries

These are tools for creating objects.

  • Sketcher CreatePoint.png Point: Draws a point.
  • Sketcher Line.png Line by 2 point: Draws a line segment from 2 points.
  • Sketcher Arc.png Arc: Draws an arc segment from center, radius, start angle and end angle.
  • Sketcher CreateArc3Point.png Arc by 3 Point: Draws an arc segment from two endpoints and another point on the circumference.
  • Sketcher Circle.png Circle: Draws a circle from center and radius.
  • Sketcher CreateCircle3Point.png Circle by 3 Point : Draws a circle from three points on the circumference.
  • Sketcher Conics.png Create a conic:
    • Sketcher CreateEllipse.png Ellipse by center : Draws an ellipse by center point, major radius point and minor radius point. (v0.15)
    • Sketcher CreateEllipse 3points.png Ellipse by 3 points : Draws an ellipse by major diameter (2 points) and minor radius point. (v0.15)
    • Sketcher Elliptical Arc.png Arc of ellipse : Draws an arc of ellipse by center point, major radius point, starting point and ending point. (v0.15)
    • Sketcher Hyperbolic Arc.png Arc of hyperbola: Draws an arc of hyperbola. (v0.17)
    • Sketcher Parabolic Arc.png Arc of parabola: Draws an arc of parabola. (v0.17)
  • Sketcher CreatePolyline.png Polyline (multiple-point line): Draws a line made of multiple line segments. Pressing the M key while drawing a Polyline toggles between the different polyline modes.
  • Sketcher CreateRectangle.png Rectangle: Draws a rectangle from 2 opposite points.
  • Sketcher CreateTriangle.png Triangle: Draws a regular triangle inscribed in a construction geometry circle. (v0.15)
  • Sketcher CreateSquare.png Square: Draws a regular square inscribed in a construction geometry circle. (v0.15)
  • Sketcher CreatePentagon.png Pentagon: Draws a regular pentagon inscribed in a construction geometry circle. (v0.15)
  • Sketcher CreateHexagon.png Hexagon: Draws a regular hexagon inscribed in a construction geometry circle. (v0.15)
  • Sketcher CreateHeptagon.png Heptagon: Draws a regular heptagon inscribed in a construction geometry circle. (v0.15)
  • Sketcher CreateOctagon.png Octagon: Draws a regular octagon inscribed in a construction geometry circle. (v0.15)
  • Sketcher CreateSlot.png Slot: Draws an oval by selecting the center of one semicircle and an endpoint of the other semicircle.
  • Sketcher CreateFillet.png Fillet: Makes a fillet between two lines joined at one point. Select both lines or click on the corner point, then activate the tool.
  • Sketcher Trimming.png Trimming: Trims a line, circle or arc with respect to the clicked point.
  • Sketcher External.png External Geometry: Creates an edge linked to external geometry.
  • Sketcher ToggleConstruction.png Construction Mode: A construction object will be shown in blue and will not be used in a 3D geometry operation. It is only visible while editing the Sketch that contains it. Selecting existing Sketcher geometry and then clicking this tool toggles that geometry between regular and construction mode. Selecting this tool when no Sketcher geometry is selected changes the mode (regular vs. construction) in which future objects will be created.

Sketcher Constraints

Constraints are used to define lengths, set rules between sketch elements, and to lock the sketch along the vertical and horizontal axes. Some constraints require the Helper constraints

Not associated with numeric data

  • Sketcher ConstrainCoincident.png Coincident: Affixes a point onto (coincident with) one or more other points.
  • Sketcher ConstrainPointOnObject.png Point On Object: Affixes a point onto another object such as a line, arc, or axis.
  • Constraint Vertical.png Vertical: Constrains the selected lines or polyline elements to a true vertical orientation. More than one object can be selected before applying this constraint.
  • Constraint Horizontal.png Horizontal: Constrains the selected lines or polyline elements to a true horizontal orientation. More than one object can be selected before applying this constraint.
  • Sketcher ConstrainParallel.png Parallel: Constrains two or more lines parallel to one another.
  • Sketcher ConstrainPerpendicular.png Perpendicular: Constrains two lines perpendicular to one another, or constrains a line perpendicular to an arc endpoint.
  • Constraint Tangent.png Tangent: Creates a tangent constraint between two selected entities, or a co-linear constraint between two line segments. A line segment does not have to lie directly on an arc or circle to be constrained tangent to that arc or circle.
  • Sketcher ConstrainEqual.png Equal Length: Constrains two selected entities equal to one another. If used on circles or arcs their radii will be set equal.
  • Sketcher ConstrainSymmetric.png Symmetric: Constrains two points symmetrically about a line, or constrains the first two selected points symmetrically about a third selected point.
  • Sketcher ConstrainBlock.png Constrain Block: v0.17 and above Basically allows to block a geometric element in place with a single constraint. It should be particularly useful to work with B-Splines. See the Block Constraint forum topic.

Associated with numeric data

For these constraints you can use the expressions. The data may be taken from a spreadsheet.

  • Sketcher ConstrainLock.png Lock: Constrains the selected item by setting vertical and horizontal distances relative to the origin, thereby locking the location of that item. These constraint distances can be edited later.
  • Sketcher ConstrainDistanceX.png Horizontal Distance: Fixes the horizontal distance between two points or line endpoints. If only one item is selected, the distance is set to the origin.
  • Sketcher ConstrainDistanceY.png Vertical Distance: Fixes the vertical distance between 2 points or line endpoints. If only one item is selected, the distance is set to the origin.
  • Sketcher ConstrainDistance.png Distance: Defines the distance of a selected line by constraining its length, or defines the distance between two points by constraining the distance between them.
  • Sketcher ConstrainRadius.png Radius: Defines the radius of a selected arc or circle by constraining the radius.
  • Constraint InternalAngle.png Internal Angle: Defines the internal angle between two selected lines.
  • Constraint SnellsLaw.png Snell's Law: Constrains two lines to obey a refraction law to simulate the light going through an interface. (v 0.15)
  • Constraint InternalAlignment.png Internal Alignment: Aligns selected elements to selected shape (e.g. a line to become major axis of an ellipse).


  • Sketcher ToggleConstraint.png Toggle Constraint: Toggles the toolbar or the selected constraints to/from reference mode. v0.16

Other

  • Sketcher NewSketch.png New sketch: Creates‎ a new sketch on a selected face or plane. If no face is selected while this tool is executed the user is prompted to select a plane from a pop-up window.
  • Sketcher ViewSketch.png View sketch: Sets the model view perpendicular to the sketch plane.
  • Validate sketch: It allows you to check if there are in the tolerance of different points and to match them.
  • Sketcher MirrorSketch.png Mirror sketch: Mirror a sketch along the x-axis, the y-axis or the origin [v 0.16]


  • Sketcher CloseShape.png Close Shape: Creates a closed shape by applying coincident constraints to endpoints [v 0.15]
  • Sketcher ConnectLines.png Connect Edges: Connect sketcher elements by applying coincident constraints to endpoints [v 0.15]
  • Sketcher Element Ellipse All.png Show/Hide internal geometry: Recreates missing/deletes unneeded geometry aligned to internal geometry of a selected element (applicable only to ellipse so far). [v 0.15]
  • Sketcher Symmetry.png Symmetry: Copies a sketcher element symmetrical to a chosen line [v 0.16]
  • Sketcher Clone.png Clone: Clones a sketcher element [v 0.16]
  • Sketcher Copy.png Copy: Copies a sketcher element [v 0.16]
