How to model a corrugated metal silo?

Hi Pros,

I need a hint in how to model the body of this silo. I have no clue how I can model the profile of the corrugated metal in a cylindrical form. Bezier curve and then loft it? Is there a more efficient way?

Many thanks in advance for a suggestion or maybe a video tutorial user added image

make a cylinder with height subdivisions, then scale some of them like on the screenshot, then you can bevel the loops, if needed.

Hi Mickha,

Thank you for the suggestion. With this method the space between the profiles is too large. The profile should really looks like a wave.

Some other ideas on how to model this?

adjust space between edge loops and scale face loops then.

Hi tweetytunes,

I will wait for your tip, of course!

What I have done till today is:
Created a wave line with an EP curve, duplicated the line and lofted it. Converted to Poly, duplicated and stitched together, applied a non-linear bend to it (180°).

I'm just wondering if there some other workflows to do this beside mickhah suggestion and my workflow above.

You could create one "ring" with polys, getting the profile just right, then duplicate special all the way up, combine, and merge.

OK - Looking at the ref image this morning it is hard to see what kind of shape you are you looking for, but still think I can help here.

I have created 3 examples for you - The zip file has a fbx file that can be used. See image 1
Image 2 points out the process I used to create the 2nd and 3rd one, sorry not more images on that one but Maya crashed.

Hope it helps - but that ref image is not the greatest to see the shape of the metal.

Hi tweetytunes,

Many thanks for your suggestions as well as the files. Looks also good and could be one way to take in consideration.
As I wrote before in the thread, I've modeled one starting with a simple EP curve, duplicating the curve, applying a NURBS loft, converting to Poly, applying a non-linear deformer (bend). The corrugation is vertically and not horizontally, but I think this doesn't matter.
Below you can see the model that I have already textured in hurry. That would be also a way, what do you think about?
Enjoy the weekend.
