Skin removal and skin expansion

Recommended Posts

Hello @Link. The skin expansion is helpful when you have a skin surface with a wall on top of it. Expanding the skin will push the skin further under the wall and this can avoid ugliness if the infill density below the skin is not high. It's also useful for removing small gaps that can occur in skin when a small feature lies on top of skin, e.g. lettering.


The skin removal feature is used to shrink back skin before it is expanded. So if you shrink and expand by the same amount, the result will be the same? Not if any of the skin area becomes so narrow that it completely disappears. That's the main use for shrinking the skin.

Hope this helps.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
