How to Extrude Wrapped Text

I have read MANY articles/posts and watched many video's on this topic and I am still not able to figure it out (which is sad).

I have some text which is wrapped around a cylinder more than 180 degree's (see image below).

I have read that I need to create an offset surface and project my text onto this offset surface...the problem is that the text wraps around the entire cylinder. I can NOT project all the wrapped text on an offset sketch plane (does this make sense?).

Here is a very boiled down image of what I would like to wrap/extrude:

The Following is a quick guide on how to wrap 'text' around a cylinder 360 degree's.

I received help from Antonius and Frank on this process.

I am sure there are other ways to skin this cat but this works for me (I hope this helps someone out).

Step #1: Create Datum Plane Tangent to cylinder.

Step #2: Sketch 'Text' on Datum Plane.

Step #3: Create a 'Designated Area' out of the 'text':

Step #4: Prepare for Spinal Bend by Creating the following:

Step #4a: Create Bend Trajectory Sketch as shown below (in this example...create a circle and divide it at the tangent point assoicated to the Datum Plane in Step #1)

Step #4b: Create datum plane located at the end of the 'text' as shown:

Step #5: Create a 'Spinal Bend' of the 'text'.

Besure to pick the correct starting point (as shown below):

Here is what the 'spinal bend' feature looks like (as shown below):

Step #6: Final Step....'Thicken' the 'Spinal Bend' feature.....

Again, I am sure there is more than one way to do this (and I wish PTC would just let us extrude a wrapped sketch....but at the moment we can not...are you listening PTC??)

I hope this helps someone. Goodluck!!!

Thanks again to Antonius and Frank for their help!!

It can be done and you have to play with it.

The idea in this case is that you wrap the text as you have done.

You cannot project a sketch with "text" in the sketch. You have to "offset" the curves of text.

In your case, you would do maybe 4 offsets, one at every 90 degrees (maybe 120x3).

Offset is the way you create a raised area on a curved surface. In this case, you wrap the text onto the cylinder and you "project" it back to a flat plane (now distorted and squished). You then Offset these distorted sketches onto the surface.

Are you using the full version of Creo 2.0 parametric?

I am using WF5.

I did read somewhere that I might have to project 'multiple' sections of my text because it wraps around the cylinder....this just seem crazy to me.

I also tried using the 'Torodial Bend' command (see images below). I was successful in bending just a sketch and extrude but NOT successfuly when trying to bend text around a cylinder.

I guess I was hoping for something simple and not have to do 4 offsets (or maybe 3 offsets at 120 degs) like you suggested.

I think I read that

I have not found a better way to manage consistent offsets from curved surfaces. And there are options with the offset feature. Not sure what limitations WF5 adds, but in general, things are not any easier in Creo.

Spinal bends can work if the plane only distorts in one direction. Careful control over the spinal bend feature will remove distortion and properly wrap as expected.

This text wrapped more than 360 degrees.

Since you can't extrude text as a surface (enhancement needed!) I had to create the text first, then toroidial bend that, then create the cylinder using the curve to drive the diameter, ensuring the text stays put. Pretty simple though.

As Antonius mentioned, you can use pi and other relations to force dims to be what you want. I used a perimiter dim (love 'em for toroidial bends!) and a reference dim to make things equal and avoid distortion.
