![]() These helper constraints are plain regular constraints. So, as the constraint is invoked, the point will be automatically constrained onto both curves ( helper constraints will be added, if necessary), and the angle between curves will be constrained at the point. The point should be specified explicitly, since curves typically intersect in more than one point.įor the constraint to work correctly, the point must be on both curves. The intersection point can be on curves' extensions. In this mode, angle between two curves is constrained at the point of their intersection. It is not required that the lines intersect.īetween curves at intersection (angle-via-point)Īccepted selection: any line/curve + any line/curve + any point In this mode, the constraint sets the angle between two lines. In this mode, the constraint fixes angular span of a circular arc. It is the angle between the line and X axis of the sketch. The constraint sets the polar angle of line's direction. Entering a negative value will cause the angle direction to flip. Note: The angle can be entered as an expression that will be evaluated and the result will be stored.Īs with any datum constraint, it is possible to change the angle value later by double-clicking the constraint in constraint list or 3d view. Using the Sketch → Sketcher constraints → Constrain angle form the top menu entry.Pressing the Constrain angle button in the toolbar.Invoke the constraint using several methods:.The mode will be chosen depending on the selection. Select one, two or three entities in the sketch.To apply angle constraint, one should the follow the steps: There are four different ways the constraint can be applied: It is capable of setting slopes of individual lines, angles between lines, angles of intersections of curves, and angle spans of circular arcs. 3.4 Between curves at intersection (angle-via-point)Īngle constraint is a datum constraint intended to fix angles in sketch.
