Sketcher ConstrainDistance/pt-br

Description
Constrain distance defines the length of a line, the perpendicular distance between a point and a line, the distance between two points, or,, the distance between the edges of two circles.



Usage

 * 1) Pick one line, or one point and one line, or two points, or the edges of two circles.
 * 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. 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.

Hint
If applicable please consider using the or  constraints instead. These constraints are more robust and faster to calculate than the ConstrainDistance tool.

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:
