The 
Hem command enables you to create hems of various types on edges of a selected solid.
Depending on the option selected in the Type drop-down list, you can create the following types of hem.
 |
Simple | A flange with a fixed angle of 180° having minimum possible value of the diameter and user defined Length (1). |  |
 |
Double | A double flange with fixed angles of 180° having minimum possible value of the diameters and user defined Length (1). |  |
 |
Teardrop | A flange with an angle greater than 180° having user defined Length (1) and Diameter (2). |  |
 |
Rolled | A flange with a fixed angle of 270° having user defined Diameter (2). |  |
Apart from the Length and Diameter of the hem, the following parameters can also be defined.
| Extensions | It controls the distances from the endpoints of the selected edge. |
| Side Angles 1 | It defines the angles of the flange (Simple hem) or the first flange ( Double hem). |
| Side Angles 2 | It defines the angles of the second flange (only for Double hem). |
| Note For a Rolled hem, only the Extensions can be defined. |
