Cable Assembly Techniques (Reference Assembly: CABLE1)

1. "Red" Component: This component was assembled using three (3) constraints- anaxis align, a mate offset, and an align "orient". The last constraint allows you to control

the orientation with respect to the axis of the hole. In your assembly, this wasaccomplished by mating or aligning two datum planes that run through the axis of thehole. However, this assumes that an assembly or part datum already exists through thehole. If it does not, an "orient" constraint can be used to control the orientation withrespect to the axis. With an "orient", two (2) selected surfaces or planes are made

parallel to one another, but not necessarily coincident, or coplanar. Edit thedefinition of this component to observe this. (You can also use an "align- angle offset"constraint to rotate the component, as well).

2. "White" Component: This component was also placed with an "orient" constraint. Inthis case, however, an assembly datum plane at an angle of 45 degrees was createdbefore the component was inserted. The "align" orient constraint then forces the datum

plane on the "White" component to be parallel to the assembly plane. The componentcan then be "rotated" by editing the rotation value of the assembly plane. With both ofthese components, note that the "aligning" planes are parallel to one another but are notcoplanar!

3. "Blue" Component: This component was placed using the technique that I describedthis morning- using "placement" and "move" together. This requires, however, that thecomponent be assembled as "packaged" (non-parametric) or by using Pro Mechanismconstraints- pin, slider joints, etc. This is why I did not describe it in greater detail. Withthis method, you can dynamically spin the model about the axis to any angle that youwant.

4. "Grey" Component: This component was place with just two constraints- an axisalign and a mate offset. With "assembly assumptions" checked, this is enough to placethe component, but Pro/E makes an assumption as to the orientation of the part withrespect to the assembly. We noticed this phenomenon this morning when we placedyour second assembly in the assembly. I then performed a "copy", "paste special" onthis component, specifying a rotation value of 34.3 degrees. I then deleted the original"grey" component.

As you can see, there are a number of ways to produce the "reorientation" effect thatwe discussed this morning. If you look at the "back" view of the assembly, you can seethe results of these various operations. Please review this assembly. If you would likeme to go over this with you (or other members of you illustrious group), please let me

know.
