Sketcher ConstrainDistance/cs

Popis
Vazba Délka nastavuje délku přímky, kolmou vzdálenost mezi bodem a přímkou nebo vzdálenost mezi dvěma body.



Použití

 * 1) Pick one line, or one point and one line, or two points, or the edges of two circles, or the edge of one circle and one line.
 * 2) There are several ways to invoke the command:
 * 3) * Press the button in the Sketcher toolbar.
 * 4) * Use the then  keyboard shortcut.
 * 5) * Use the entry from the top menu.
 * 6) A pop up dialog opens to edit or confirm the value. Press  to validate.

Note: the constraint tool can also be started with no prior selection (apart from circle to circle and circle to line cases). To set the perpendicular distance between a point and a line, the point needs to be selected first. By default the command will be in continue mode to create new constraints; press the right mouse button or once to quit the command.

Rada
Pokud uvažujete o její aplikaci, zamyslete se raději nad použitím vazeb Horizontální vzdálenost nebo vertikální vzdálenost. Tyto vazby jsou robustnější a mají rychlejší výpočet než zde popisovaná vazba Délka.

Scripting
Distance from origin:

Distance between two vertices:

Length of line (the GUI allows selecting the edge itself, but it is just a shorthand for using the two extremities of the same line):

Distance from point to perpendicular point on line :

Distance between the edges of two circles:

The Sketcher scripting page explains the values which can be used for, , , , , , , and , and contains further examples on how to create constraints from Python scripts.
