Create a bent steel sheet

Hi fellas!

What steps would you take to model a steel sheet where the edges are bent according to the picture below as easy as possible? Both vertically and horisontally inwards. Need to create quite many and they need to be created as model-in-Place (adjustable to other geometries in project)

 

Right now it's created as an extrusion, but the extrusion is only vertical (made in plan).
Red lines are missing.

 


Thanks in advance!

Here s an example of a loadable component. Screencast shows the creation. I forgot to film the way to parametize the circles so just take a look at the attached family.

Thanks.
This is what we're aiming for. But with a bent sheet on the top and bottom.

I would advise to avoid realistic bending (unless you are a manufacturer). Just dig a hole to create sheet thickness like shown before. Its enough to do a presentation. 

 

For those circles, you need to create an array. Are you familiar with the arrays?

You mean with a radius for the corners? Sure, I guess we'll avoid that and let the details show how they look.
In short, create a volume and void it?

Sure, I'm familiar with arrays. Could be a bit tricky creating an array that updates as it should when the measurements changes though. Also having the array around corners(?).

Personally I would avoid modelling this level of detail in Revit. I probably would model a family with simple plate (parameters for length, width and height). For presnetation I probably would use a material.

I would use details to clarify about holes and exact shapes of the plates.

Using many voids, arrays and in-place families will probably give  a big hit on Revit performance

 

If fabrication is important and many plates have to be made I would use Inventor (or similar). That software has sheet metal function were you can create bend radius and create holes at the right position, even create holes along bends.

Please mention Revit version, especially when uploading Revit files.

Interesting, maybe we should try creating the sheets in inventor. How's the learning curve? Does it take a long time to get it right? Can we import the sheets into Revit to see the final result?

The thing is that we 'need' to have the sheets in Revit. We need to see that everything fits and that the aesthetic part works out. But I guess that it can be done in another software and then imported if it isn't too much of a struggle.

Offtopic:
I get what you're saying, but the main question is: Why do Revit struggle with simple tasks like this?
ALOT more complicated geometries and functions are made in gaming softwares, why are we chained with perfomance issues like this? When will it be solved?

I would say the learning curve is similar to Revit.

It is possible to export files in a way that can be imported to Revit.

But also then I only would do this at the end of the project. Because I still expect slowdown when importing files witth this level of detail

 

The things you are asking of Revit is pushing close to the edge of Revits capabilities. Revit is intended for whole building design and used as a BIM Tool. A metal sheet with bends and a bunch of holes are very small details compared to a complete building. So you could say that Revit is not designed for the kind of work you want it to do.

You are basically in a grey area, that is inbetween software like Inventor and Revit.  

 

Game Engines and Revit ar two completely different things. So comparisons are not useful.
