With this objects you can handle sketches solve the actual set of geometry and constraints add a geometric object to the sketch delete a geometric object from the sketch delete all the geometry objects and constraints from the sketch except external geometry switch a geometry to a construction line set construction mode of a geometry on or off add a constraint to the sketch delete a constraint from the sketch Rename a constraint of the sketch copy another sketch's geometry and constraints add a link to an external geometry to use it in a constraint delete a external geometry link from the sketch delete coincident constraints associated with a sketch point set the Datum of a Distance or Angle constraint Get the value of a datum constraint set the Driving status of a datum constraint Get the Driving status of a datum constraint toggle the Driving status of a datum constraint set the VirtualSpace status of a constraint Get the VirtualSpace status of a constraint toggle the VirtualSpace status of a constraint movePoint(GeoIndex,PointPos,Vector,[relative]) - move a given point (or curve) to another location. It moves the specified point (or curve) to the given location by adding some temporary weak constraints and solve the sketch. This method is mostly used to allow the user to drag some portions of the sketch in real time by e.g. the mouse and it works only for underconstrained portions of the sketch. The argument 'relative', if present, states if the new location is given relatively to the current one. getPoint(GeoIndex,PointPos) - retrieve the vector of a point in the sketch return an axis based on the corresponding construction line create fillet between two edges or at a point trim a curve with a given id at a given reference point extend a curve to new start and end positions add a symmetric geometric objects to the sketch with respect to a reference point or line add a copy of geometric objects to the sketch displaced by a vector3d add an array of size cols by rows where each element is a copy of the selected geometric objects displaced by a vector3d in the cols direction and by a vector perpendicular to it in the rows direction Deprecated -- use exposeInternalGeometry Deprecated -- use deleteUnusedInternalGeometry Exposes all internal geometry of an object supporting internal geometry Deletes all unused (not further constrained) internal geometry Approximates the given geometry with a B-Spline Increases the given BSpline Degree by a number of degrees Increases or reduces the given BSpline knot multiplicity calculateAngleViaPoint(GeoId1, GeoId2, px, py) - calculates angle between curves identified by GeoId1 and GeoId2 at point (x,y). The point must be on intersection of the curves, otherwise the result may be useless (except line-to-line, where (0,0) is OK). Returned value is in radians. isPointOnObject(GeoIdCurve, float x, float y) - tests if the point (x,y) geometrically lies on a curve (e.g. ellipse). It treats lines as infinite, arcs as full circles/ellipses/etc. Returns boolean value. calculateConstraintError(index) - calculates the error function of the constraint identified by its index and returns the signed error value. The error value roughly corresponds to by how much the constraint is violated. If the constraint internally has more than one error function, the returned value is RMS of all errors (sign is lost in this case). changeConstraintsLocking(bLock) - locks or unlocks all tangent and perpendicular constraints. (Constraint locking prevents it from flipping to another valid configuration, when e.g. external geometry is updated from outside.) The sketch solve is not triggered by the function, but the SketchObject is touched (a recompute will be necessary). The geometry should not be affected by the function. The bLock argument specifies, what to do. If true, all constraints are unlocked and locked again. If false, all tangent and perp. constraints are unlocked. Number of Constraints in this sketch Number of geometric objects in this sketch Return the number of construction lines in the sketch which can be used as axes
