I am trying to show text on the side of a cylinder, where the text is a
constant depth and wrapped a round the surface. I know how to show text on a
flat surface, but am having no luck creating text on a cylindrical surface.
Has any body any suggestions!

Either one of a couple methods will work. The one I like is to create the
text on a plane inside the cylinder when the part still is solid. Before
holes, shells, cutouts, etc. Execute the boss extrude "offset from a
surface" command. Don't forget to choose the OD as the surface to offset
from while the dialog box is open. Plug in some small offset value. If you
can't initially see the text then click on the reverse offset to other side
box. Please note that using this method the sides of the text as they wrap
around the cylinder text will always be perpendicular to the plane.

The other method is to create the text on a plane any distance outside the
OD of the part. Boss extrude to the OD using up to next or up to surface.
Extrude cut the top of the test off with a circle or arc that is offset from
the od by the height of the text.

Hope this helps

Very interesting question indeed. This problem has its root from the 2D graphic design, where the designers always want the character to follow some specific path.
 
For solidwork, if you want to do any extrude feature, you must have a flat plan as your base for the sketch.
 
Solidwork won't be able to extrude from a surface. And when you do the extrude feature, you are always extruding somthing normal to your original sketch plan. Imagine you have a round hemisphere with a square sketch at the bottom, when you do the extrude, SW just won't fill the hemisphere completely.
 
I hope the SW design team can do something on this in their next release.

I'm not sure if I understand the problem correctly, but if the
text is not too large and is parallel to the axis, then you might
try sketching the text on a plane that is tangent to the cylinder
and then extruding a cut with the end condition "offset from
surface."  If the text is wrapped circumferentialy, then you
may have to use the above process for each letter with sketch
planes at different angles.

I did have one other idea that I'm not sure will work, but
you might try creating a sheet metal cylinder and cutting
the text in the flat pattern.

Well... if you looked at my example I am extruding from the cylindrical
face.
If you perform a split line function (The text to the cylindrical surface)
knit those into separate surfaces, you can then thicken / cut or boss. This
will
either grow or shrink the extrusion in a radial value away or towards the
center of the cylinder.

Jack,

Can you email to me your sample file, as I try several time and cannot
repeat what you have. I would like to see how you do it.

I start using the blend on cylindrical feature, unroll to flatten state,
then put the text on, but interesting enough, the text only perform on plan
surface. When it is back to roll up state, we cannot get any extrude
feature.

Great idea using the cylindrical sheet metal feature. I've got text wrapping around my cylinder beautifully.

I'm not John, but anyway:

It does (only ??) work when you model a flat plate, and turn it into a
cilinder by 'insert bends' and create the bend in the 'flat sketch'.

Lem,
 
I also work on this text on Cylinder for some time, and still cannot get satisfactory result.
 
As from your experience, the flatten up method from the sheet metal handling in SW won't be a good solution.
 
The main solution to this lay on whether we can put text on the circumference of the cylinder, and be extrude from the surface to any length we want.
 
I think it is more easy to solve this in Rhino.
 
Anyone got a solution ???????

Well, I finally did manage to get the text to cut the cylinder,
but the text only reads right from the inside of the cylinder.
Also, the text cuts completely through the sheet metal so
that letters having a closed loop (like "o") are missing the
portion enclosed by the loop.

If anyone has gotten this to work better than this, PLEASE
send me a zipped file so I can figure out what I'm missing.

Thanks in advance,

I don't know if this will work with sheet metal, but what I have done in
the past (for making bike grips) was to ofset the surface of the
cylinder to the height needed then create a plane tanget to the surface
slightly higher than the ofset surface, create the text on the new plane
and extrude it (up to a surface) to the cylinder. Then use the ofset
surface to 'cut' away the un-needed solid. This way the text has the
same shape as the cylinder and will automatically grow or shrink in
direct relationship to the cylinder.

If this is what you might need let me know and I can run you through my
exact steps.

Johnathen,

The solution is better than none.

If we have very wide angle of text, we might have to divide into several
plan to complete the task.

Anyway, thanks for your hints.

Jack,
The method you used just happened to work because you used the word "TEXT" and
projected each letter separately. At least that is what I am assuming, because
the Split Line function will not work with greater than one closed profile.
This means that it would not work with letters A, B, D, etc. It is a good idea,
but limited in its usage.

Regards,
Dave Murray

David,

I try your method, It can only do a cut feature,

If we need extrude, the text just won't stay on the surface of the cylinder.

We still have to look for better solution on this.

Richard,

You've received many useful suggestions in response to your
posting and it's a shame that the sheet metal technique does
not allow for "embossed" text - only a "stencil" effect is
possible.

The following involves more work than simply using a text sketch
entity, however, it can solve your problem even for a free-form
surface:

1. Create a sketch on a plane that is normal (or essentially so)
to the surface your text will be applied. The sketch should have
a series of lines each made approximately normal to the above surface
and should have ends that remain close to, but inside the surface.

(In the case of your cylinder, these lines would all radiate from its'
center and stop short of the I.D.)

2. The lines in the above sketch are then used in creating a series
of new planes with the "perpendicular to curve" option with the origins
at the endpoints near the inside face of the surface. You could have
one plane for each letter or for each word, etc.

3. On the new sketch planes you can then insert sketch text entities
to be extruded offset from the above surface (or up to a surface that
was offset from it).

To adjust the spacing between letters or words, you can open up the
sketch created in step 1 to reposition one or more of the lines that
control the text sketch plane locations.

Keep in mind that if you have a symbol which has been made as a custom
True Type font character, it is possible to introduce a single sketch
text entity in the form of a logo, for example.

Hope this makes sense and is of help,

Per O. Hoel

OK... This is really strange, but may work.

Take the part with the cut extruded text (don't cut all the way through to
avoid losing the centers of the 'O's)
Make a similar part, with smaller ID, but same OD.
Make an assembly with both overlaying each other
Edit the "new" part with smaller ID in the context of the assembly
Insert... Features... Cavity to cut the "stenciled" part away.

I haven't tried it, but see no reason it shouldn't work... ;)

Hi Kevin,
Stanley and I have been communicating behind the scenes. What you describe is
nearly the same method I described once I realized he was looking for embossed,
not engraved text. It works just fine. He came up with another idea as well, and
is mentioned in this thread, as you have probably already discovered. I kind of
like the cavity method best, because it isn't quite as involved, but it does
create the extra reference with the assembly. Looks good, though, and is
associative if any changes get made to the original. Still wish it were easier.
Too bad the text wouldn't just "roll up" with the cylinder when defining it as a
sheet metal part.
