Highlights

Drop points in 3D or type X, Y, Z in mm, or open a frame optimised in Topo1D or Drone Frame
Hull junctions join several members at a point without bending them
Mirror about X, Y or Z and linear or circular patterns applied to the layout
Checks name the point or member at fault; volume, area and piece count reported
STL with Z up, the cage for PolyNURBS, and save to your computer or your cloud

A question it answers

How do I turn a hand-placed strut layout into one smooth bracket with fleshy junctions that I can print?

What you put in

Points placed on a snapping work plane or typed exactly, members drawn as chains or bridged between selected points, and a gizmo to move them; one of five templates (empty, tetrahedron truss, cube frame, symmetric A-frame, organic arch), a saved .organic.json, or a frame sent from Topo1D or Drone Frame; strut radius, hub scale and standoff, with per-point body and per-member strut radius overrides; junction type (Hull, or Cube with blend rings and tension); mirror about X, Y or Z and a linear or circular pattern, applied to the point graph; preview and export subdivision levels; a minimum feature size. Lengths in mm, Z up.

What you get

The smooth solid in the 3D view; volume at the named subdivision level (shown only when the surface is a closed manifold), overall size in X, Y and Z, surface area, number of separate pieces, end-body to strut radius ratio, cage face and triangle counts and build time; checks that name the point or member at fault (too short for its end bodies, narrow angle, not connected, no members, coincident points, thinner than the minimum feature, cage defects); an on-demand self-intersection test; and exports: STL with Z up, the control cage as JSON for further editing in /nurbs, and the design as .organic.json.
