Fishmouths, cut list, weldments, etc. for a tubular assembly?

Anyone have a guide for doing this in Creo? Apparently it's built into solidworks, which is fine, except I'm on Pro/E. I've found this video: http://www.e-cognition.net/pages/Tubular.html which alludes to the ability to export by stressing the importance of keeping things up to date, but I'm wondering if anyone has a user-program to do it, or if there's something I'm missing.

 

Cut lists would be great, those and fishmouth unrolling (sheet-metal) would be amazing.

 

Ideas?

Hey David. That's pretty much how its done.

You can have a look at Brian Martin's excellent guide for doing something similar:

I think you can do this a little simpler than the video but yes, each sub-component can quickly become dependent on the assembly. No matter what, you need the trajectories for the cuts but you can manage them all from the assembly level rather than copying the "skeletons".

And yes, Creo has realistic welds. And sure, you can "develop" a cut-list methodology using the measure tools and capturing the length of curves to determine cut length. They can be gathered and presented in several ways.

    Thanks Antonius, that link is brilliant. Between that and flattening to sheetmetal and exporting the end curves I might be set. Any links to material on writing those export scripts would be really helpful, I've only really worked on small assemblies where each part was self-defined before.

    No export scripts needed.

    The top-down design process is still a collection of individual parts that simply reference a higher level assembly for its definition. As long as that associativity exists, you can change to your heart's content, and if you set up the original models well enough, it will follow changes throughout the design as you tweak it. In the background, Creo will load all the data it needs to define each part as long as it can find it.

    This also means that you can create drawings of any individual part or subassembly as it is defined in the associative assembly. You kind of have to look at the philosophy to understand there really are no limits, but plenty of pitfalls if you don't plan your project to some extent.

    You have some things to learn but you can make "annotations" of measurements. You can also create "relations" to manage your "materials". In the top level, or any sub-level assembly, you can access these relations to build bill of material data or other custom tables on the fly.

    Creo doesn't spoon feed anyone. -You- decide what you want and how you want to present it. Of course, this means, -you- have to make it do what you want.
