Design Methodology - References

What is the best design methodology for a robust part and assembly in
SW: using reference geometry (axis and datums) to create a feature or
is referencing another feature (face) as good? SW Training I have
had emphasizes feature to feature reference. My past experience in
Pro/E, but not Wildfire, the company I worked for had CAD design
methodology to use only reference geometry when creating part features
or assembly mates. This takes extra time and makes the part more
cluttered, but in Pro/E it is more robust. One of the reasons being
recovering from geometry or assembly errors in Pro/E 2001 and prior
versions is more difficult. Comments?

SW is the same as Pro in this regard, and I expect any other parametric
modeler as well. Skeletal modeling is the way to go.

I really don't work with large assemblies but everything I've read
says that Solidworks seems to fall apart when you use lots of top down
design.

The reason I use reference geometry is to make it easier to identify
where I have added design intent for both myself (I often can't
remember my design intent 2 weeks later) and someone else who may want
to change my model.

Good luck finding anything on how to use reference geometry in the
link published above. It's also not properly covered properly in Matt
Lombards SolidWorks Bible. It is properly covered in the
SolidProfessor videos and I bet it's properly covered in the myigetit
course but I have not subscribe to it as of yet... still have a few
weeks to go finishing up the SolidProfessor videos.

If your looking for more feedback (and why shouldn't you be!) I would
post this question on the Engineering Tips SolidWorks Forum.

Fixed you mangled quotes, idiot.

Or much of anything else.

Hence all it''s users doing good work.

Buzzword Psychois again.

One hole or two?

Buzzword Psychosis zone again.

IOW "change" == "correct" or "fix"..

Both probably expected you to have clue #1.

Still a beginner, eh?

No clues, eh?

Run out of ads & free demos?

And the second time ... ?

Are you banned there too?

LOL
