Design approach help

It's not a very easy process, but I don't think it much matters whether the
text is extruded or not.

You can have zero-thickness text or graphics on surfaces. That's what the
Split Line and Wrap functions give you.

I don't think you need to do that. When you pattern your buttons, you can
also pattern the cuts, so there is only one feature added.

Well, almost. Keypads are usually compression molded out of silicone rubber.
We tried injection molding a keypad out of polyurethane, but the urethane
was too stiff at cold temperatures and it was very difficult to injection
mold the very thin walls that you can get in compression molding.

But that is a very fine distinction. The design rules for compression and
injection molding are not all that different.

It depends upon the part. A case part is typically done from the outside in.
You generate the basic shape, then shell it, then add the bosses, ribs,
recesses, vents, holes and other features that you need.

For a keypad, you might want to go the other direction or not. In the old
days, before multi-body parts, you would probably make the flat bottom piece
as the first bit, then add the buttons. I would probably be inclined to go
that way still, just because the feature scope often gets lost on multi-body
parts and causes unexpected errors to show up later on.

Don't get too discouraged. You bit off a lot for a new user. You may find
after you get a bit more familiar with the software that you won't have so
many problems. On the other hand, since you're not afraid to push the
envelope, you may find the cherries and strange behavior to be more or less
normal.

Nice analogy!

Well, As someone who managed to avoid ever having to learn Acad, I
think part of the swamp you are in is simply called "change" or
"different".

Completely integrated is elegant, but for many of your suppliers it
really will not help them.

For many processes like pad printing, silk-screen etc., an EPS or
illustrator file is best. it is vector based artwork, and scales
perfectly. They need 2D computer art. SW does not output this type of
result well. And you suppliers are not going to apply graphics form a
native CAD file. Usually there is a design or artwork preperation
department, and they are going to use Illustrator or similar product,
and will want an EPS file. So it is best if you (or a graphic designer)
make that based on a 1:1 line drawing from SW. In fact, I was just
doing one today for a client to use for embossed graphics. The graphic
will be photoetched, and I will supple the EPS file with guidelines to
align to the part features.

Having the graphic on the CAD model might be useful for in-house QA,
but often they will want an arwork film 1:1 that they can overly onto
the product to check.

If you were doing keycaps like a computer, with molded graphics, that
is another story. Then you might want to model the type font as a 3D
object.

I hear ya...
In another thread here, there apparently will be the feature in 2006
for applying graphics that are visible all the time when working. If
true, that will be very cool! But I would caution, that sounds like
eye-candy and not a technical documentation feature for production
artwork.

Always a sensible thing to do...

There will be others... not to worry

Hmmm. I imagine that they will still work from an EPS file.

If you REALLY want to do this... and since your caps are flat... Import
the text, or create the text as a sketch. Perhaps one cap at a time.
Then, use insert > curve > split line, and that will give you a
separate surface in the shape of your letter. You may need to do
several operations for letters with open centers, like "o" "p" etc.
Then select the surface of the letter and change the color using edit
Color. That will look very good. But again, I do not suggest this as a
means for technical documentation since the artwork is not parametric
to the part and vise versa.

Enjoy!

This is where you want to use Insert/Features/Wrap instead of Split Line. It
lets you do more than closed curve at a time.

Thanks Jerry, I have actually never used that tool. I was interested in
testing that after reading the long thread about cam paths.....

See! Gotta try something new every day! But... I already did once
today, so I will try this tomorrow ;-) Besides, it is beer time
here.... ;-)

Cheers,
