Truss — for 3D printing (.obj)

Station Scale (model units per real foot) Export OBJ

Saves as .obj.txt — this viewer only allows a fixed set of download extensions, so rename it to .obj after downloading to open it in a slicer or 3D viewer. Web members still fading in or out at that station are left out.

Whole structure — every truss, combined (.obj)

Scale (model units per real foot) Include purlins Include decking surface Export OBJ

All stations (Truss A, Truss B, and every in-between truss) in one file, saved as .obj.txt — rename to .obj after downloading. Web members still fading in or out at a given station are left out, same as the single-truss export above.

Decking — flat pattern for cutting

Scale (drawing units per real foot) Segments

Developability score right now: 100% — lower scores are more likely to overlap when flattened; more segments or Optimize lofting usually helps.

SVG downloads directly. DXF saves as .dxf.txt — rename to .dxf after downloading.
