Translations:Sketcher ConstrainCoincident/3/en

As stated above, this tool takes two arguments - both are points. the command will cause the two points to become coincident and be replaced by a single point.
 * 1) First, it is necessary to highlight two distinct points. ( this will not work if, for example, you attempt to select the start and end point of the same straight line; selecting the start and end points of an arc will produce a closed circle or ellipse but will constrain the location of the seam to be on that point).
 * 2) Highlighting of a drawing item is achieved by moving the mouse over the item and clicking the left-mouse-button.
 * 3) It is also possible to highlight all items inside a rectangle by clicking and dragging. When dragging from left to right (with any vertical motion), only the shapes which are entirely contained within the rectangle will be highlighted; in the other direction all shapes which intersect with the selection rectangle will be highlighted. This can be used to select only the vertices without selecting the edges, by dragging a small recangle around some vertices from left to right, as long as there are no edges which are fully contained within the rectangle.
 * 4) A highlighted item will change its color to green. (This color can be customized in )
 * 5) Subsequent items can be highlighted by repeating the above procedure(s).  it's unnecessary to hold-down any special key like  to achieve multiple item selection in a drawing.
 * 6) Once you have two points highlighted, you can invoke the command using several methods:
 * 7) * Pressing on the constraint button in the toolbar.
 * 8) * Using the keyboard shortcut.
 * 9) * Using the entry in the top menu.
