Sprue Inner Branches

Sprue Inner Branches

Sprue Inner Branches grows branches from the center of a ring out to its interior — the sprue for rings whose inside carries holes or delicate work, like a full eternity band, where a branch standing on the shank interior has nowhere safe to land.

In the selection panel:

• Mesh Selection — the ring to sprue.
• Branch Growth Point — where the branches grow from, typically the center of the ring.

In the parameters panel:

• Height — lets the branches start at a different height than the ring’s center.
• Add Branches — pick the endpoint of each branch, on contact areas clear of crucial features or holes.
• Delete Branches — one button removes them all; to delete a single branch, hold Shift and click its gumball.
• Diameters — the branch diameter at its start and at the contact point with the mesh.
• Symmetry — mirrors the branches for symmetrical designs.

When the lower interior of the shank is smooth and can host a main branch, use Sprue Inner Tree instead.
