Flange protection & wrap analysis
DAMAGE & WRAP PLANNING

Protect the flanges and finish

Illustrative inputs below. Replace them with your material, measured film force, and packaging load case. This screen compares wrap positions for the selected layout.

Material, wrapping and shipping assumptions
0 = example geometry; STL needs a value.
Use the narrowest load-bearing strip.
Used for the sliding screen only.
Separate hypothetical load case per flange.
Records intent; does not add thickness or protection to the geometry.
Local flange bending / yield—
Shock bending / yield—
Sliding demand / capacity—

Amber markers = screened flange load points. Red = calculated wrap stress reaches yield. Hidden while parts are separated.

Search notes & comparison
Geometry-aware nesting

Open bends can share space. The search compares compact shapes with nested arrangements.

From parts to a finished package

  1. Pipeline: choose the next part or order. Quality holds appear first.
  2. Prepare: grab the shown quantity, inspect while assembling, wrap where shown, and place it on the shelf. Press Bundle Ready and repeat.
  3. Package: start with the proposed arrangement. Drag bundles to adjust it, or choose Arrange for Me for another suggestion.
  4. Verify: review fit and support issues, confirm the physical packing checks, then complete the package.

Controls: click to select, drag to move, R to rotate 90°, F to flip, Shift-click to select more, Delete to remove. Ctrl/Cmd+Z undoes; Ctrl+Y or Cmd+Shift+Z redoes. Drag empty space to orbit and scroll to zoom. Every common action also has a button.

Choose More for orders, history, settings and demo tools. Detailed geometry and wrapping controls stay under Advanced.

How the geometry and screening work
  1. Fit the actual bends. The search uses occupied geometry cells, leaving open areas available for other parts.
  2. Keep it wrappable. It favors compact cross-sections and shorter bounding wrap perimeters over long, awkward rows.
  3. Inspect the arrangement. Use End view to see how bends interleave. Separate parts to inspect their order. Fitted bands follow the convex outer contour across the film width and bridge recesses.

Support priority. Looks for broader nearby side faces, fewer isolated parts and connected groups. Face area is estimated on the collision grid at the selected clearance. It is potential support, not verified metal contact; gaps need suitable separation material if support is intended. Separate damage screening adds entered material and shipping load assumptions; it does not establish safe packaging or predict scratch depth.

Scope of this prototype. One repeated part per bundle. Translation is across the bundle, with aligned lengths and optional quarter-turn rotations. It does not search tilted or length-staggered arrangements. STL geometry supports bends in any direction, within that placement model.

Results are heuristic candidates, not a guaranteed global optimum. Collision checks use a conservative grid. Small gaps may reflect grid resolution. Assembly paths and nonlinear deformation are not simulated. Damage screening uses entered forces, mass, friction and material properties in simplified load cases. Check whether the proposed parts can actually be inserted and held together.

Profile examples use square bend corners. For formed radii and production geometry, import the actual solid STL. STEP import is not included.
