Wrap on Conical Surface

SWks 2006 will "Wrap" text or other sketch items on a cylindrical
surface only.

I'm not at a place with 2007 today, and wonder if a cone can have text
wrapped on its outer surface (to simulate a label) in the current
release.

Anyone tried it?

Thanks - Bo

 

I just did it in 2006 (working there today). However, the sketch plane has
to be tangent to the cone, so that the text wraps at an angle to the cone's
base. It seems that there is no way to wrap text parallel to the base
without some other steps. 2007 seems no different in this regard.

 

I'll be danged, I never thought of the plane being parallel to a
tangent plane.

Thank you so much. This will be a help to all the others like me who
are only partially functional...

Good Stuff - Bo

 

Just to add to it, as I haven't tried it yet, but if you wanted to get the
text parallel to the base as well, I would think if you created the text on
a guide curve of the correct radius for the base first, then wrapped it, you
should be good....

No "Guide Curve" setup in the Wrap command yet.

No, but I just did it....You create a new sketch on a plane tangent to the
surface....In that sketch, create an appropriate arc, then Tools--> sketch
entity-->Text. In the sketch text properties select curve, then select the
arc and modify your text
however you want it. After you're done, make sure you change the arc to
"for construction" or the wrap will fail. Close the sketch, then highlight
it form the tree, select Wrap and select the surface....

If this isn't what you want, then I misunderstood...Sorry

Interesting solution, but the construction curve would need to be a segment
of an ellipse (in a conic section sense) wouldn't it? I'd also be
interested (if I had time) to try wrapping text onto a cylindrical surface
and then use a radiate surface to project it onto the cone. That could get
really ugly though...

I forgot how to calculate the appropriate proportions of the ellipse to
correspond to the angle of the cone, but a good drafting text should have
an equation describing the relationship. You'd have to do some adapting,
but that would be the meat of it. IIRC AutoCAD's ELLIPSE command allowed
you to specify an ellipse by major axis and angle for the purpose of
drawing isometric and oblique views. Those were the dark times...

 

Hmmm- Yes you are correct, it should be an ellipse. I was just playing
around with the idea of bending the text first before wrapping, so it would
appear correct after. (Funny thing is I thought of this discussion last
night, as I watched "How it's Made" on the science channel last night with
my kid, and they were making bicycle helmets and showing how the artwork for
the shell had to be drawn distorted so it would appear correct after molding
it into shape. Kind of cool show if you haven't seen it before.....)

This whole issue started with an innocuous round plastic fitting, like
many other parts I had done and "wrapped" text around.

The ultimate thing different than before was that there was 1/4 degree
of draft on the OD of the part (not recommended in the practical
wisdom of design manuals, but entirely workable under many conditions
and materials, when not over packed).

That small 1/4 degree draft prevented the "Wrap" function from
working.
