How to place a decal image in a multi curve surface

[ND_10940562]

Hello everyone, I’m using Creo 8.0.9 and I need to create a sticker adapted to the surface, but for that I’m using a decal.
When the sticker is flat, applying the decal is easy, but when it’s curved, it becomes very difficult.
Is there a better method?
Or is there any parameter in the planar mode that can be set to automatically adapt to all surfaces?
the surface its a extrude on a spinal bend

There are some tips in this video that may apply to your problem.

How to apply an image or decal to a Creo Parametric model as a texture - EAC Tip of the Week

Almost but for me the planar its  very difficult

ps planar isnt that diifficult thank you

Hi

It's unclear how this response was classified as an Accepted Solution because it doesn't address the issue in @ND_10940562.

The quilt in this case has multiple surfaces, and the appearance is applied to each one separately in Creo. Using a decal as a texture will not result in a uniform appearance across the entire quilt. A different approach is required to ensure even coverage across all surfaces.

In my view, my replies are getting mixed up, even though I’m responding to each comment individually.
However, after watching the suggested video and applying the decal using the planar method, that was what actually worked.

Hi @ND_10940562 

The result looks great!

Could you share a video showing how you managed to do it? Alternatively, could you also attach a simplified model that

includes the bent ruler?

This isn't going to directly help you, but maybe fuel a push for an upgrade ....

In Creo 12 there is a new feature that allows you to approximate surfaces (Model tab -> Editing -> Down arrow menu -> Approximate surfaces)

This tool will take multiple surfaces and merge them into one. Once you have 1 surface you can apply your decal.

If you aren't allowed to use Creo 12 in production and you didn't care about the surface being parametric, then you could approximate the surface in Creo 12, export it out and import it into your model in Creo 8. Not a recommended practice because its not parametric, but if you know your part is never going to change, that could work in a pinch.

Good to know thank you

Are you doing this just to get a "cartoon" or do you need to use the non-planar geometry for engineering purposes? Have you considered creating the scale text and hash marks on the part using sketched datum curves in the planar configuration and then apply the spinal bend? If possible, I would also limit the construction of the curve used to drive the spinal bend to generate surfaces that can be developed (Gaussian curvature of zero). So don't use a spline to drive the spinal bend if you want to have surfaces that can be flattened.

Have you considered applying the hash marks and text directly (datum curves) to a surface in the model in the flat state? They should go with the surface when the spinal bend is applied. If you want to try building the scale into a model and need to control it via relations then look at the solution of this thread, there is a sample video and reference model showing how to parametrically control the scale and text of the datum curves.

the skecthe of the sticker has to much entities, make things slow. Thank you.
