Upload a flat blank or the 3D part. Stripnest finds the strip layout and coil width that use the least steel per part, and hands you a DXF.

Stripnest develops a formed part from a STEP file into its flat blank, finds the bend lines and nests the blank on the strip. It also runs a forming check on the part: thinning, how much of the forming limit is used, and springback at every bend. The part below is Stripnest's own result. Turn it and take a look.
The colours are the forming check Stripnest ran on this part (DC04, 2 mm sheet): grey where the sheet is bent but hardly stretched, green where it is stretched and still inside the forming limit. Red, yellow, purple and blue would flag cracks, crack risk, excessive thinning and compression. This is an estimate from the finished part's geometry (one-step strains), not a full forming simulation: no tools, binder, friction or forming sequence. Use it to find hot spots before you quote, and confirm parts near a limit with a simulation or a tryout.
On a finished layout, Stripnest sets out the die's stations one pitch apart and suggests a starting sequence: pilot holes and piercing first, then notching and trimming, a station for each bend, cut-off last. Add, move or delete stations and operations until the plan matches your die, then download it as a PDF for the quote or the toolroom.
Stations × pitch; guides and end plates come on top. A plan for the die quote, not a die design.
The flat blank as DXF or IGES, or the formed 3D part as STEP: Stripnest unfolds it for you.
Distance between parts and to the edge, carriers, how far the part may turn, and the widest coil you can buy.
Watch the layout improve live, then download it as DXF, with a PDF report for the quote.
It tries far more than the usual 1-up, 2-up and mirrored layouts, and picks the coil width together with the layout.
Move, rotate, add or lock parts and change carriers and clearances by hand. Every clearance is re-checked while you drag, and the solver can re-optimise whatever you leave unlocked.
Move points, redraw an edge between two points as a tangent curve or a straight line, delete a hole, draw bend lines. The original stays in your library; the edit is saved as a new part.
Every distance between parts and to the edge is re-measured on the true outline, arcs and holes included.
DXF with true arcs, plus cost per part, scrap per 1000 parts and cutting force.
Stations, press force and die length, plus part and die cost worked out from your shop's own rates, as a PDF.

Try it on your own parts.
For the die designer.
For tool shops and quoting.
The flat blank as DXF or IGES, or the finished 3D part as STEP. From a STEP solid Stripnest develops the flat blank itself: bends unroll exactly, stretched areas are estimated, and the result is shown for you to check.
