Create a Hem in a Sheet Metal Face
Sheet metal hem features are typically added to provide one or more thicknesses of material along an edge of a face or flange.
A hem provides stiffness to a design, or provides a smooth, rounded external edge on a part to eliminate sharp edges.
You can create single, double, rolled, and teardrop hems.
On the ribbon, click Sheet Metal tab
Create panel
Hem
.
In the Type drop-down list, click one of the following:
- Single

- Teardrop

- Rolled

- Double

In the Shape panel, click Select Edge
and select an edge. If you want to flip the direction of the hem, click Flip Direction
.
To specify how the width of the hem, click More, and then click one of the following options in the Width Extents drop-down list:
- Edge Creates the hem on the selected edge.
- Width Creates a hem of a specified width at a specified offset from a selected vertex, work point, work plane, or planar face on the edge of a face. You can also specify that the hem is a specific width, centered on the midpoint of the selected edge.
- Offset Creates a hem offset from two selected vertices, work points, work planes or planar faces on the edge of a face.
- From/To Starts and ends the hem from selected points or planar faces intersecting the selected edge.
(Optional) In the Gap drop-down list, use Measure, Show Dimensions, or Parameter List to obtain a value from the model.
- Gap For Single and Double hem types, specifies the distance between the inside faces of the hem.
- Length For Single and Double hem types, specifies the length of the hem.
- Radius For Rolled and Teardrop hem shapes, specifies the bend radius to apply at the bend.
- Angle For Rolled and Teardrop hem shapes, specifies the angle that is applied to the hem.
