Training needed for surfaces.

hank_debey

My objective is to create a chest piece for administering negative pressure (vacuum) to the torso of a person. This link shows examples of what I am trying to achieve. https://docs.google.com/presentation/d/15tuNJY2e178RN8cGLOswHT1Xjjv0-ujU7aTFH942pxE/edit?usp=sharing  

This is a link to my OnShape document as it currently exists. https://cad.onshape.com/documents/10c18c662bad614d8b596468/w/39a93246a95042f54bf46f22/e/e31526292f8cf71ee67b5e2e?renderMode=0&uiState=642adb410b983c5fe2cb9383 

I would appreciate it if tutorials could be recommended that would help me understand how to accomplish two things.

1. Create a surface, later to be thickened, that is attached to the blue structures in the model.  

2. Once a basic surface is attached, then I want to learn how to manipulate the surface to create an aesthetic shape.

Thanks for any recommendations.

Have you had a look at these allready?

And another important tip is to make sure that everything you design is editable in an easy way, with variables or configurations
Seeing the pictures I would go for creating a mould and then Vacuumform the shape.

IMO, do these 3 first, in the order indicated. Generally, you need to understand curves first, as the surfaces are built onto them.

You may also want to do this course. What you have now is the body scan and the vacuum device in the same studio. If you use the "In-Context" method, your part studio would only contain the vacuum assembly you are designing, not the body. You'd then see the body and the vacuum together in a standard assembly. What In-Context lets you do, is temporarily see them together, while designing the vacuum, and even make geometry references to the body. This method will keep your part studio less cluttered, and increase its performance (incase the body scan slows it down).

@dirk_van_der_vaart Thanks. I have gone through some of those and others are yet to be done.

@nick_papageorge073 Thanks for those links. I am working my way through them.
