Translations:Assembly Basic Tutorial/24/en

Up to now we discussed all details of moving things around with placements and the objects involved in it. It is however very tedious to calculate all placements by hand and set them manual via the property editor. It would be more pleasant if it would be possible to set simple relations between parts instead of abstract rotations and translations. Therefore FreeCAD introduces assembly constraints. As the name indicates, they work the same way as in the sketcher: the user applies different attributes to geometries of the parts. This can be for example the distance between two points, or their orientation (parallel, perpendicular) of lines etc. FreeCAD trys then to find placements which satisfy all given constraints.
