Draw a Silicone with a Irregular Geometric Shape in CAD

[User2012]

I should design a Silicone model for a Breast Cancer Survivor. My problem is the IrregularGeometric Shape of silicone. I tried "Sphere"/ "Loft" commands,but I didn't get my desired outcome! I also drew the 2D base by "Spline"; however,"Extrusion" was not a good option to make it look like a 3D silicone! Any ideas!

Did you use a series of profiles when you tried the LOFT command?

 

Have you considered the possibility of using a mesh object?

[User2012]

I just tried to use "Mesh Sphere" and Modify it then, and also Loft (see attachment). However, I didn't get the desired outcome.

Yes, I could see where it would be a bit of a challenge to derive the exact shape. Having worked as a surgical technician at one time I am familiar with the implants.

[User2012]

I see! It becomes even more challenging for an actual size. Please keep me posted if you come out with any new idea. Thanx!

I am not at my CAD computer so there will be no experimenting today unfortunately.

 

Is this a class project? The wording of your first sentence in your starting post seems a bit strange.

Breast implants can be round or anatomical (i.e.-teardrop, contoured or shaped). Why did you pick the one shown in your first post?

"Triangle Breast Form" is what I'mlooking for at this time. It looks more like the new image enclosed

Loft will be key.

But I think I would use something like Autodesk Inventor or Alias rather than Autodesk AutoCAD.

[User2012]

How about Solidworks?

[JD Mather]

SolidWorks is equivalent to Inventor.

If you have access to that - I would use it rather than AutoCAD.

I think LOFT might be the way to go as well. You could try playing around with the MESH command - which is a pretty good way to form some organic shapes.

 

This was created using LOFT and 3 shapes.

 

 

Let me know if I can help any further.
