Shell

About this Block

What it does: The Shell block hollows out an Implicit Body with a thickened outer wall. Common uses:

• Lightweighting solid parts

Tips:

• The wall is thickened Inward, Outward, or equally in both directions with the Center input.
• It is ideal for lightweighting, and works well when combined with the Volume Lattice block to fill the hollow space with lattice.
• You can vary shell thickness using a Ramp block: (https://support.ntopology.com/hc/articles/4411539633683)
• What happens if you shell a boolean union inward: (https://support.ntopology.com/hc/articles/4403375026451)
