Datum planes

We can use datum planes as a tool in creating other features,
such as cylinder, cone, sphere, revolved solid bodies.
datum planes also created a feature in another angle than usual for the faces of the target solids.
we can create two types of datum planes: the relative and fixed





datum planes used are usually:
-Relative Datum Planes
Datum Planes relative made in reference to another object in our model. we can use the curves, faces, edges, points,
and other references as an object reference to Datum Planes. There are various methods that we can use to make Datum Planes.
we can make relatively Datum Planes in several agencies.
-Fixed Datum Planes
Fixed Datum Planes do not include and not limited by any other geometric object,
except when used in user-defined features. we can use one method for Relative Datum Planes
Fixed Datum Planes made by deselecting the option in the dialog associative Plane Datum.
There are also special methods that can be used to make reference Datum Planes remain based WCS and the Absolute coordinate system and by using the coefficient in the equation.
