Tangency relation

This relation allows an element to be positioned in tangency on another.

Creation Stages / Use:

Click the icon or select the 2D sketch > Constraints > Relations > Tangency... command from the drop-down menu. In a Draft document, select the Sketch > Constraints > Relations > Tangency... command from the drop-down menu.

Select the two elements to be made tangent: the two elements are moved and the Tangency symbol is displayed between the two elements.
It is possible to select a tangency point. This point is necessary in some cases (tangency between 2 splines) but it can be optional in other situations (tangency between a line and a circle). But this points must be selected before the second geometry.

To delete the Tangency relation, you must select the Tangency symbol then press the Del key on your keyboard and choose the command Delete from the popup menu displayed by right-clicking.

Modifications / Additional information:

You can quickly create a tangency constraint between a line and an arc by selecting the line or arc close to the tangency point then displacing it until the display of the tangency symbol is obtained.
