Dimensions, tolerances and assemblies
Dimensions
-
-
-
-
Extension line offset
Gap between the object surface and the extension line, so it is not confused with the visible lines of the model
-
-
Chain dimension
Should only be used if the function of the object would not be affected by the accumulation of the torlerances
-

-
Assemblies
-
-
Types of joints
-
Revolute
Has a single rotational degree of freedom, much like a hinge
Can rotate around the standard X,Y or Z axis or around an edge in the model
-
-
Pin slot
Allows two degrees of freedom, but components can rotate around different axes
Planar
-
Allows two directions of translation in a plane and a single rotational direction normal to that plane
