How to Extrude Wrapped Text

ptc-5737990 — Fri, 04 May 2018 16:55:29 GMT

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

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.

I see you are using toroidal bend in your samples. Spinal bends may be a little simpler.

The white text is a simple extrude; right justified on a tangent sketch plane to the cylinder (extrude 2).
The spine sketch (sketch 5) 1" circle with the end divided at the tangent sketch plane for the extrude.
Datum DTM9 is offset from the default plane at "pi" (the cylinder is 1", circumference 1"*pi). This is the "area" the spinal bend will operate on. This will asure no distortion other than thickness.
The spinal bend is straight forward... The solid text (white); the selected spine - ensure the start point of the spine is correct; and DTM9 for the region to be bent.

You can use perimeter dimensions in your spine sketch for more involved shapes to know where to place your "region" datum plane.

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.

Oh and offset, while a decent tool for some things, cannot do this, at least on the version I have.

Trying to add draft failed, and to get "draft" I simply swept a cut along the edge of the text just for fun after I posted this. THAT worked.

Offset works but can get finicky with angles or rounds.

Also, it works like a "project", not a "wrap", at least in my version. The farther you get off center the worse it gets.

Re: How to Extrude Wrapped Text

TomD.inPDX — Tue, 24 Jun 2014 21:34:05 GMT

Correct... it doesn't wrap at all but does project normal to the target surface. That is why you 1st wrap; then project to flat plane, and then offset back to the surface. A lot of work, really.

TOO much. I'd thought about making a surface, trimming that, spinal bending that, then thickening it, but you can't pick all the elements of a curve made of text to use to trim a surface, so you're hosed. If you could do that it'd be more flexible. That and the fact you can't easily extrude text as a surface is why I did the wrapped text as the first solid feature. A kluge, for sure, but it worked.

Hmmmm, now I have another idea!

I played a little more with toroidal bend. Intuition aside, it does provide a different interface from spinal bend but you are stuck using a cylindrical bend profile.

OK, so, for some stupid reason you can't use text in a fill feature either, but I made a datum curve of text, made a fill surface using edges of all the letters (loops, was only a little tedious), did a spinal bend on that, then thickened that surface. Wasn't too painful 95 features vs. 3), but it allows for several spinal bends anywhere in the model tree if needed. If any of the surface commands allowed text this would be SO much simpler (back to 3 features). Makes no sense that they don't.

In the cosmetic features area, Creo 2.0 now has a "designated area" feaure.

This will fill text directly from a sketch.

Here a toroidal bend is acting on the resulting surface quilt of the Designated Area feature.

I found this by accident. And you are right, many commands do not recognize sketch text as a valid geometric feature.

Ok, just for fun......

Hmmm, gonna have to try that tomorrow, thanks!

Re: How to Extrude Wrapped Text

TomD.inPDX — Tue, 24 Jun 2014 23:30:58 GMT

A very quick "wavy" banner.

Sketch 1 is a text sketch

Designated Area 1 is the flat filled surface

Sketch 3 is a spline sketch using perimeter control

The Spinal Bend is just that, the Designated Area (quilt) projected onto Sketch 3.
