Adding Ribs Inside A Rectangular Tank

Adding Ribs Inside A Rectangular Tank

Adding Ribs Inside A Rectangular Tank

(OP)
I am kind of new to Creo. And, I am trying to add some ribs inside a rectangular tank. I looked online and on YouTube, but their techniques don't seem to work. Maybe I'm missing a step.

Can someone give me a way that they create ribs inside a tank?

Thanks!




RE: Adding Ribs Inside A Rectangular Tank

How do you expect to manufacture the ribs inside the tank?

(OP)
It is going to be roto molded. I asked the plastic company, if we can add ribs, and, they said yes.

RE: Adding Ribs Inside A Rectangular Tank

I would have modeled the solid part to represent the outside surface and then used the shell operator to remove the interior. This would duplicate roto-molding. Starting from where you are is a lot of little pieces patching.

RE: Adding Ribs Inside A Rectangular Tank

(OP)
I did use the shell function after I did the basic tank.

So, what's the best way to add ribs?

RE: Adding Ribs Inside A Rectangular Tank

The ribs can only be made with protrusions from the mold. So unshell this, add the cuts that represent the mold features that will create the ribs, shell it again.
