Gusset plate
Define two legs and their included angle, trim any of the three theoretical vertices, and optionally add a row of holes along the diagonal edge.
Triangle definition
Shape the gusset
Vertex trims
Origin values locate the root cut. Define each far-end trim by its setback along the leg or by the perpendicular cut length.
Hypotenuse holes
One continuous exterior contour with true tangent arcs and optional circular interior cuts.
Geometry only. Gusset dimensions are not an engineering recommendation; consult a licensed engineer for structural applications.
Outline-first preview
Finished plate
Finished dimensions reflect the trimmed contour. Dashed lines and crosses show the original triangle and are not exported.
Use a plain triangle, clip fine ends for weld access, or make deep cuts that resemble structural corner and bicycle-frame gussets.
Dashed extensions and vertex crosses explain how the entered leg lengths relate to the finished trimmed outline.
This tool creates geometry only. It does not size, rate, or certify a gusset for a structural load.
