Can a projected sketch curve be extruded?

[njchen24]

Greetings:

I have created a part (it's a label) in assembly mode using projected
sketch curve onto a cylinder. It consists of a rectangular profile
with Title, Model #, P/N using WF1 build 2003410 default "font". Is it
possible to protrude this projected sketch to a depth of .05" away from
the projected surface?

Your suggestion and help is greatly appreciated.

John.

From a PTC Suggested Technique (can I do this without attracting the
attention of legal eagles?):

"Create an offset feature by pre-selecting the side surface of the cylinder
as shown in Figure 3. Pick Edit > Offset. In the dashboard, change the
offset type from Standard to Expand. Click Options from the dashboard, and
pick Sketched Region and set the Side surface type to Normal to surface. A
Sketch collector then appears in the dashboard. Pick the Create a section
icon and select the offset datum plane created in Step 1 as the sketching
plane. In Sketcher, Sketch > Edge > Use > Loop and pick each datum curve
letter created in Step 2. Once all letters have been selected, click Sketch

Done. The depth of the feature is shown in the dashboard. Use the Flip

material side icon to change the direction of the offset. This determines
if the text will be cut into the cylinder or extruded out from the
cylinder."

Think that's enough to get you started. If you look at the Offset Surface
in Help, it gives you a rundown on the various options. (I'd guess that if
you search sites like mcadcentral.com there are examples that you can
download.)

When I've done this before (pre-WF), I didn't first project or wrap the text
curves onto a surface. I'm not sure what difference it would have made if I'd
first taken this additional step. But, because the surface the text was offset
from was only mildly curvy, putting the text on a plane, then kind of copying the
text to the surface and simultaneously offsetting it worked fine. My question is
this: do the curves need to be projected/wrapped first? is it a problem if they're
already projected onto the surface?

A planar sketch is required for the feature, but if need be (the text will
be distorted by the projection) you can first Wrap the text then project
those curves back to the Offset feature internal sketch (Use Edge, Loop).
