Dear All,

In design modeller, I want to create two separate bodies(two separate parts) using different sketches. When I create a new sketch and make it 3D, the new 3D body and previous 3D body are known as 1 Part, however, I want them to be 2 separate parts.

Does anybody know how to do that.

Kind regards,
ashtonJ

Did you use the Search option? there are plenty of topics relating your question as your post regarding the "Revolve in Design Modeller" you could search before asking... Tutorials are a good way to get started with DM and the WB in general.

But I give you a hint, use "add frozen" when you create your second body.

I have same question (as ashton) and I tried following options to make them separate two bodies, unfortunately din't work ;

1> add frozen ( i wanted interface between two bodies, so when i was setting physics in "Pre", it considered it only one body.

2>. using offset TO CREATE 2ND BODY in same plane, because both solid bodies are boxes and placed one above the other (with one common face) ,it again results in same problem, 1 part,1 body.

could you please point out my mistake??

Thanks

Danial,

The add frozen option should work. I don't have enough info from your post to help you further. Could you please add an image of your problem and what you are trying to model. Add the .agdb file

You are nearly there, just select the two parts, right click >form new part and then it should be fine.

Thanks, though it worked without forming new part but still i learnt a new thing by forming new part , it could be done. cheers

Thanks again

Can I know how did you build two parts with common face with out using the form new paart,I have the same problem.
Thanks

In design modeller, I want to create and meshing two CUBIC that one of them is in the other one with separate bodies(two separate parts) using different sketches.
please help me.
I could create two cubic in geometry space, create larger one then create smaller one in different skeche with select add frozen instead of add material,but when I want to generate mesh ,some error would be created.

Does anybody know how to do that.

@msara
Instead of frozen, use "slice". That should do the job. Two separate bodies will be created.

Cheers !

1) Extrude the first body using the first sketch
2) When you extrude the second body from the second sketch, instead of "frozen", try "slice"

The slice option will slice the body 1 as body from sketch 2 is extruded. Try this out and let me know if this works for meshing.

The issue is, with frozen, the two bodies are treated independently. The problem arises when one body is inside the another. When you choose frozen, the first body and second body both exist. So an overlap of volumes is created which causes the problem. Slice option extrudes body from sketch 2 while subtracting the intersection portion. So no overlaps
thermal energy and Fedor like this.

ya. if you do with frozen, you will have two independent body. But if you use slice option you will have two separate bodies. The interface will have src, trg and several wall regions. If you add to bodies using form new part, you will have interace common to both bodies. But you will have interface regions with
wall-part-fluid, wall-part-solid, wall-part-fluid-part-solid, and shadow regions.
Does anyone know why this happens? How to create common interface?

add frozen!

Try few tutorials, cuz all these things are covered in tutorials.
Plus you can very well try all 3 options and see what different things you are getting.
It will help in future!


Cheers

How can I create 2 or 3 part, 1 body.
In my case 1/2 body is inside the another. When I choose frozen, the first body and second body both exist. So an overlap of volumes is created which causes the problem. I also tried with the 'slice' option; it results same as 'frozen' option.

Please help....
