Hem folds an edge of a sheet metal part right back on itself. A hemmed edge is safe to hold (no sharp cut edge) and much stiffer. It works like Hem in Onshape and SOLIDWORKS.

How to use it#

  1. Click Hem.
  2. Click each edge to hem (click a picked edge again to drop it).
  3. Choose the Type and set its size.
  4. Click ✓.

Options#

OptionWhat it does
TypeFlat: pressed down onto the sheet. Open: folded back with a gap. Rolled: rolled round past halfway, with no flat part.
LengthFlat and open hems: from the outside of the fold to the end of the hem.
GapOpen hems: the gap between the hem and the sheet.
Radius and AngleRolled hems: the inside radius of the roll and how far round it goes (181° to 270°).
PositionInside: the outside of the fold is where the edge was, so the part keeps its size. Outside: the fold starts at the edge.
InsetA hem shorter than its edge.
Fold the other wayThe hem folds to the other side of the sheet.

Tips#

  • Hems on edges that meet at a corner are mitred, so they do not run into each other.
  • In the workshop, fold a flat hem to about 45° in the bending brake, then close it flat with a mallet or in the folder.
