Complex shape modeling

Anonymous — Thu, 02 Aug 2018 09:54:16 GMT

Hi guys,

So I'm trying to model a complex shape as in the picture below, I've tried different ways to create this shape but I alawys fail.

So I'm asking if there is anyway that I can remove the intersections of the panels shown in the picture to get the reqired shape?

and if there are any other ideas to create this model, please suggest it 🙂

models are attached,

thanks 😄

@Anonymous Artur Kosakowski marked post as the solution. If it did not work as an answer, please post your reply in this thread so that I can unmark the solution.

Do you want a spheric dome or the curve d panel strips are to be cylindrical?

Hi @mustafahesenow,

First of all, thanks for the new method that I've learned from you,

but when I did it to the whole shape, the meshing got really bad and not defined on the element correctly!

So what am I doing wrong, in order to avoid these problems? thanks.

Here is an example of what I got some areas without mesh, model is attached.

Hi @Rafacascudo,

what I want is similar to a dome but with some cuttings (I don't have a word for this shape ) , but the picture below shows the shape I want.

Any ideas? I'm still facing errors when I do this model.

Thanks.

Hi @Anonymous

I'm attaching the meshed model however you need to have RSA 2019 to open it.

Hi @Artur.Kosakowski

Thanks for helping , but can you tell me the method used to do the model , or the meshing?

btw the attachement is an image.

Thanks

Hi @Anonymous

Conversion to ACIS and Union of all panels however with some additional action that you will not be able to do in the current commercial version of RSA.

I'm attaching the rtd file I missed. I hope it will help.

Hi @Artur.Kosakowski,

I mannaged to do my model, however compared to your results, I've found a difference!

So by any chance if you can check my model and see what I've done wrong ?

The first picture is your model displacement after changing the supports to fixed, the below it is my model!

and thanks alot @Artur.Kosakowski

Hi @Anonymous

Check the materials (thickness in both models).

Hi @Artur.Kosakowski,

In my model when I try to change the thickness it doesn't change , every thing in the properties tab doesn't change! what is the reason?

Thanks.

Hi @Anonymous

For extruded / revolved / ACIS panels the thickness label is not displayed in the Inspector as it is assigned to its sides.

Hi @Anonymous

Do you still need any additional help for your model? If we managed to provide you with the solution would you mind marking the corresponding post as such? Thank you.
