How to shell a COMPLEX GENERATIVE DESIGN PART???

[ZEBAS70]

Hi I’m working on a really complex generative design part in inventor and I want to shell my solid part. I’ve tried everything!!!

I’ve tried shell

I've tried thicken/offset from solid and surface

I’ve tried free form thicken

but haven’t had any result. I don’t know what else to try!!!

I have the solid part, the surface and the freeform. Please help me !!!Files here

Hi! It took a quick look at the part. The original geometry was Mesh or Freeform, right? If yes, couldn't you do Thicken within Freeform?

Many thanks!

Hi! Johnson thank you so much for your help

The original geometry was exported from another software and it was a solid part. Then I made it a mesh and then a freeform. Yes, I’ve tried the thicken command within Freeform, but I can only select one body the time!!!... I’ll add another image to the post. Thanks for your help !!!

Hi! You will need to use Merge Edges command to merge those Freeform faces before you can thicken it.

Many thanks!

Hey I tried doing what you said it works !!!! nice...but I can't merge all the edges at one....I'll have to do it manually one by one and there are 616 surface bodies  .... is there another way I can merge all edges at once??

@ZEBAS70,

make small steps as in the pattern..

Hi S_May thanks for your reply....yes I've tried working out small parts of the model  ..... I think that could be an option.... but I'm going to do some FEA after that so I don't know if the small parts will really be joint together...actually there are some sections where this error message show up !!! Thanks anyway
