TôlerieCAD in 1 minute
From a drawn outline to a folded, drilled and animated part; standard parts, faceted STEP unfolding and the surfaces workshop.
Recorded with the French interface; the software also runs in your language.

From flat pattern to folded part. And back.
TôlerieCAD folds your DXF files in 3D, unfolds your STEP parts into flat patterns ready for cutting, and calculates square-to-rounds, cones and warped surfaces for the shop floor.
DXF ↔ 3DSTEP → flat patternPress brake5 languages
2D → 3D
Folding a flat pattern
- DXF with bends, angles and radii
- Folded part, solid, STEP export
- Flat pattern drawn on a blank sheet
3D → 2D
Unfolding a STEP part
- Bent sheet metal, solid or surface
- Warped surfaces faceted in triangles
- Thickness detected, DXF for cutting
∅ → ▭
Plate work
- Square-to-round, cone, cylinder, hopper
- 3D surfaces workshop and branches
- Inside, outside or mean dimensions
Bent sheet metal
Draw, bend, drill: the 3D follows every click
Draw the outline on a blank sheet or open a DXF. Every flange, hole or notch updates the folded part.
- Flanges, bends, tabs, reliefs added with one click on an edge
- Holes, slots, cut-outs placed with the mouse or by distances to the edges
- 3D hole drilled on the folded part and transferred to the flat pattern, even across a bend
- Manufacturability checks: flange too short for the die, hole in a bend zone
Plate work
Square-to-rounds, cones, cylinders and hoppers in seconds
Enter inside, outside or mean-line dimensions. The flat pattern is calculated generator by generator and refolds exactly.
- Square-to-round, centred or offset, bends fanning out from the corners
- Cone, right or eccentric, truncated or full
- Cylinder cut straight or at an angle for elbows
- Hopper rectangle to rectangle, angle, channel, tray
3D surfaces
The surfaces workshop: sketch, drill, facet
Curves in dimensioned views, ruled surfaces, NURBS, sweeps and pipes. The flat pattern is faceted with the number of bends you set.
- Boolean cut-outs: a closed outline projected onto the surface drills or trims it
- Triangulated warped surfaces: each twisted facet is folded along its diagonal
- STEP unfolding of warped surfaces, like a shop-floor layout
- Send the flat patterns to TôlerieCAD for dimensioning and DXF
Press brake
The bend sequence checked before the shop floor
Punch and die are simulated for every step. TôlerieCAD searches for a collision-free sequence and compensates springback.
- Step-by-step simulation with gooseneck punch and V-die
- Automatic sequence free of tooling collisions
- Springback calculated (E, Re) or measured: angle to program
- Bend tables by material, thickness and die opening
