split surface (for different colours)

[Zestje]

Hello,

I want to split the surface of a part so I can display a symbol on it in a different colour.
E.g. Imagine a simple black block with a circle on the top surface that should be white.

When I split the surface with a curve or other surface I can set different colours, but then I can no longer solidify the part!

Is there a way to do this? I do not want to use the 'offset trick' of simply creating an offset surface and giving that surface a different colour, because that's a bad solution for the assembly and the drawing.

And if there is a solution to this problem: can I split the surface of an already solid part too?

Thank you!

Select the surface with Geometry as the selection type.

Hit CTRL+C CTRL+V to paste an exact copy.

Project the boundary curve you want to split it with onto the surface.

Select the Copy Quilt and click the Trim icon and then pick the curve
you want to split it with. Then you can color this surface differently.



To make sure you dont trim the original surface you should hide it using the model tree before working on the Copied Surface.

Thank you for your answer, but this is almost identcial to the offset trick.

I want the coloured surface to be part of the sold model.Is that possible?

check it up. hope it is what you want 2006-10-27_090358_prt0001.prt.rar

I have found that when a surface that coincides with a solid surface, the color of the solid surface bleeds through the surface. Offseting the surface a small amount will prevent this.

Thank you for the part. This is almost the same as what I had already tried.

Your method works becasue you have created a separate surface for the inner colour, which is different from the top surface from mathematical point of view.

If you extrude a sketched line to reproduce your surface and try then, you'll notice that ProE makes 1 surface again, because somehow they are mathematically identical :-(

My problem is that I'm using design surfaces (which cannot be rebuilt identically), so there is no way for me to use different surfaces than the one I have. I can only copy the design surface and trim it. But as mentioned, then they are mathematically identical and ProE will make 1 surface out of them when merging :-(.

The only way that I can think of to do what you want, is to create 2 models. The first is the entire part with a cut that is your circle with a given depth. The second is the entire part with a revolved cut that is everything outside and at the same depth. Now assemble the 2 models using the cylinders to align with and the planes used for the depth as mating surfaces. Either change the colrs in part mode or assembly mode. You now have an assembly representation of the part with the 2 colors. You can even bring the assembly into a manufacturing file and machine it as if it were one model. However, if you want to make a drawing out of it, you will have the circle shown up in the drawing view that wouldn't be there if it were one solid model.

@appinmi:


Unfortunately we're bound by our clients part lists and naming schemes, so in this case we're not allowed tohave an assembly instead of a single part to accomplish this. It is a very solid solution but it really shouldn't be this circuitous...

Seemsas if there really is no simple and easy way to do this in ProE. If soI find this very disappointing. Even though ProE does have great functionality there are several functions/features I still miss in ProE that I really loved in I-DEAS (besides the easy splitting of surfaces e.g.the branched model tree which gives a much better overview of the part and allows for easier construction of features in a part; extrusions with drafts included orwith the 2nd direction negative;the much better display quality when zooming in and last but not least the fabulous dynamic clipping mode, which totally sucks in ProE). Also, I find ProE often to be unneccesarily complicated and user-unfriendly.

Try to map a texture or a decal to the surface. Use a large plain image of the base color and create a dot or logo in the center area. You can then map it to the surface as a single image. I use a curve on the surface to get the scale and location correct. You can delete the curve or hide it once the scale and location of the "DOT" is correct.
