So I am currently working on modelling a picture of Baymax from Big Hero 6 for fun, and plan on 3D printing the finished product. I am modeling the various body parts and then attaching them in an assembly. I have currently modeled the body, a leg, and the head. What I noticed when I attached them though is that I would like some of the features to overshadow the overlapping. I'm definitely not explaining this right so I'll show it in pictures.
Notice how the attachment of the legs and the body doesn't create the circular form as it does in the actual picture, instead it creates a V-ish shape. The same kind of problem happens where the head should be completely round, but instead gets cut of a little with the body.
This is what the body looks like. Inside, it has two extruded cut cubes so that the two legs have something to mate to.
This is the leg, where the top portion gets mated inside the body.
What can I do to fix this problem? I am fairly new to solid works and this is a test project, so I am open to any suggestions that you have. No matter how many edits because this is more to learn how to use SolidWorks.
