endpoint of line/arc/arc-of-ellipse + endpoint of line/arc/arc-of-ellipse (i.e., two endpoints of any two curves)īetween curve and endpoint (point-to-curve tangency).The solver cannot create stable solutions for this combination and replaces the constraints appropriately. If you want this kind of tangency you must not use concidence plus the tangency between the curves/lines. This mode is applied when two endpoints of two curves were selected. In this mode, the endpoints are made coincident, and the joint is made tangent (C1-smooth, or "sharp", depending on the placement of curves before the constraint is applied). Use other modes of this constraint if the point of tangency is needed.īetween two endpoints (point-to-point tangency) It will work, but the convergence will be seriously slower, jumpier, and will require about twice as many iterations to converge than normal. It is not recommended to reconstruct the point of tangency by creating a point and constraining it to lie on both curves. between a circle and an ellipse), a helper point will be added to sketch automatically, and tangency-via-point will be applied. If direct tangency between selected curves is not supported (e.g. line + line, circle, arc, ellipse, arc-of-ellipse.This mode is applied if two curves were selected. Two curves will be made tangent, and the point of tangency will be implicit. Invoke the constraint by clicking its icon on the toolbar, or selecting the menu item, or using keyboard shortcut.Select two or three entities in the sketch.To apply tangent constraint, one should the follow the steps: between two lines to create a collinear condition.between two curves at user-defined point.between a curve and an endpoint of another curve.between two endpoints of a curve, making a smooth joint.between two curves (available not for all curves).There are five different ways the constraint can be applied: Tangent Constraint can also be used with two lines to make them colinear. The constraint is also capable of connecting two curves, forcing them tangent at the joint, thus making the joint smooth. Lines are treated infinite, and arcs are treated as full circles/ellipses. Tangent Constraint makes two curves to touch each other (be tangent).
