How do I extrude a shape to look “puffy”? I would like to draw a nonsymmetrical shape and have the extrude almost domed. One shape might look similar to a peanut, one might be a free form and the other like a snake. Any ideas?
I would try something other than extrudefor some of the sahpes you are looking for. Sweep or loft may give you better results. Here is a peanut shape.
This thread was just referenced recently in another. Might be worth a look:
I would look into some of the surfacing tutorials and the mold tools.
I did a couple of blog posts on this a couple of years ago. Lots of examples of a "puffy box" at the links below.
Thank you everyone for your ideas. They've been very helpful. I am having a difficult time applying these suggestions to irregular shaped objects like a peanut shape or for example a shape similar to the outline of Mickey Mouse. Where I would like the centers of each area to be on the same plane but all have the same general “puffiness” to them and not look like individual shapes just put together.
When I want to change a regular extrude to give it a puffy face at the end, I will often create a boundary surface that is the "puffy" that I need, making sure that it extends well past the edges. Then I use the "replace face" tool to replace the flat face with the puffy surface. SolidWorks will automatically trim and attach the edges to match up inside the replace face tool.
