In some design workflows, it is desirable to create persistent relationships
between components, to assure that components stay together when one is
moved. For instance, if your design contains a bolt/nut/washer assembly, you
might want to make sure that these individual components stay together.
You can create constraints between geometries on components. A constraint
is a relationship between geometry on two different component Some
examples of constraints are:
Align: aligns the two geometries. This could be making two plane coplanar,
or aligning the axes of two cylinders
Tangent: forces the two geometries to be tangent to each other - for instance
a plane and a cylinder, or two cylinders can be made tangent
Center: this is a special constraint that is used for operations like inserting
a bolt into a hole. It is a combination of an Align between two cylinders,
and an Align between two planes
Angle: specify the angle between the geometries - for instance 2 plane can
be at a specified angle
There are two main commands for creating constraints:
The Constrain command
The Assemble command
