Hem

SMH: Hem operation is used for flanging:

 

 

The operation enables users to “glue” a flange of the selected type to the outline of the workpiece. For flanging you should select several workpiece edges belonging to one face. Flanging can build a closed loop.

There are 6 types of flanging available:

Command parameters

Command parameters are general for sheet metal commands and are described in the corresponding subsection above.

The command automenu options are:

 

Finish input. Builds a geometry according to the given parameters. In case there are not enough parameters set, the option is not available.

Set entity Parameters. Calls a standard dialog of 3D modeling command parameters.

Exit command. Shuts down the command with cancelling all the set parameters.

Preview Operation Result. Enables/disables the standard option of 3D modeling commands review.

Add Edges. Selects the edge determining the base bending line. The option is active by default on entering the command.

Cancel Selection. Cancels all the elements selected and clears the operand window.

 

Flanging creation

A typical procedure when creating flanging is:

●To select the edge determining the base bending line;

●To select the count variant;

●To set the location;

●To choose the flanging variant from the list;

●To set the command parameters determining the flanging shape;

●To set the relief and displacement parameters if necessary;

●To set the angle machining parameters is the flanging has intersections with the workpiece;

●To set the gap value if the flanging is given for adjacent edges.

●In case it is possible to build such a flanging – finish entering. Otherwise change the parameters.
