Shown vs. Created Dimensions

Batman vs Superman (was Shown vs Created)

I use created when they get the job done, but don't hesitate to throw
created dims on a drawing when it's easier/faster/whatever.

I always had the feeling the Batman is a lot more vulnerable than
Superman - he's too human to beat Superman ... he IS human. Batman may
have cooler gear, but Superman doesn't need it.

wait ... it's only Tuesday!
hold this debate until Friday afternoon.

Shown vs. Created Dimensions

I'd never force anyone to do it one way or the other. As long as the guys in
the shop can make the part with the information on the print is all I
require.

RE: Shown vs. Created Dimensions

Don't ever use created dimensions unless it is something that is impossible with shown dimensions.

Another good time is when you are doing a casting drawing and you don't want duplicate dimensions for positions of holes and such with larger tolerances.

Why so serious?

Ask yourself this. What happens when we start using dimensioned and notes
on parts instead of drawings? Companies are starting to do it already, so
you mine as well get your engineers trained the right way.

That particular debate has been around the block too many times (search
the archives). We should consider arguing about this instead:

"Are driving dimension annotation elements better than driven
dimension annotation elements? If so then why?"

What is the general feeling about using shown dimensions? I was told to
always use them where possible from my first CAD administrator, but my
current admin doesn't like them. Just let me know if you like shown
dimensions or not and include your reasoning.

Wrong answer
Don't ever use shown dimensions unless you plan to inadvertently change
the design from the drawing.

RE: Shown vs. Created Dimensions

This has to be the most over-analyzed pro/e topic.

My opionion, and that's all it's good for, is us shown when possible and practical, use created when necessary. But, for the sake of sanity (and company profitability), don't make either a hard-fast rule that everyone must adhere to. The biggest mistake i have seen is when a company says all dimensions must be shown. Have you ever tried to detail a sheet-metal part without using created dimensions. It can be done, but it is a huge waste of time with 0 (ZERO) value added.

Have fun,

Steve

This brings up a a good point.

When you are eliminating the drawing for a part, what are the dimensions
that are displayed in the model? I would think that again, you could use
the model dims (shown equivalent) or created (similar to a reference
dimension).

I seem to recall seeing, or hearing of a cad ability that actually allows you to create a dimension in a drawing and having it now be the driver???

Shown vs. Created Dimensions

I use show dimensions mostly but on occasion will use a created
dimension. One problem with created is the inability to apply GTOLS to
the dimension with hand typing a bunch of gibberish @[@]@[@]@[@].
