Repeat pattern on surface following a curve?

Hello,

I am trying to repeat a pattern on a surface.

I would like the pattern to follow a curve (it is a closed curve).

The repetition does not follow the line. Here is screenshot to show you my problem.

Thanks for your help,

-Alisson

Re: Repeat pattern on surface following a curve?

In your image, the top checkbox allows you select an alternate origin. This is how you avoid offsets as you are experiencing.

Thanks for your reply,

I have tried to select different origins, but it the repetition still doesn't follow the curve.

Re: Repeat pattern on surface following a curve?

The alternate origin has to be the point where the original is on the curve.

What happens is that the original origin is referenced to the curve, but the pattern's origin is in what it perceives to be the center of the patterned feature.

I find this highly frustrating specially when it is only slightly off and you miss this important, sometimes critical issue.

Feel free to post the part so someone can have a look. Let us know if it is an academic version or not. Also what version it was created with.

Hi Alisson,

Can you upload the part to investigate.

Re: Repeat pattern on surface following a curve?

There are numerous posts on this subject over the years. Just do a search on 'pattern curve' & you will see. I attach a part that i once down loaded in response to the same issue, i still reference this part from time to time, if i find myself struggling with pattern curve issues. Also Doug Schaeter once gave a good explanation on curve patterns which i still find useful, i attach that too.

Thank you all for your answers.

I will have a look at the part you sent me and other posts.

Here is the part I have problems with / CREO 2.0 /

You were pretty much there, i simply redefined your original offset feature, placing it at the other end of the curve, where the start point arrow showed.

Just realized you are using Creo 2, i had saved it in Creo 3. Plus, i went back and had another look at the model & realized the patterned features were not merged to the curved quilt.

Please find attached Creo 2 model.
