About the Attached Flat Wall User Interface
The Flat user interface consists of commands, tabs, and shortcut menus. To access the Flat tab, click Sheetmetal > Flat.
Use the following configuration options to control the default values and behavior of selected tool settings:
smt_drive_tools_by_parameters—Uses parameter values as the default values of selected tool settings and to automatically update features when parameter values change.
smt_drive_bend_by_parameters—Uses parameter values to control the default value of bend angle and bend dimension location settings and to automatically update features when parameter values change.
* 
If you want to enable smt_drive_bend_by_parameters, you must also set smt_drive_tools_by_parameters to yes.
In the following descriptions, [<Parameter Value>] indicates that tool settings are controlled by parameters.
Commands
Shape list—Lists wall shapes:
Standard wall shapes:
Rectangle—Rectangular wall
Trapezoid—Trapezoidal wall
L—L-shaped wall
T—T-shaped wall
User Defined—Select to create a new wall shape using the Shape tab.
Predefined wall shapes—Saved wall shapes appear on the list when they have been accessed during the current session.
* 
You can use the Flat_shape_sketches_directory configuration option to specify the directory path to your library of predefined flat walls shapes to appear on the list.
Thickess Side—Flips the thickness to the other side of the sketch plane.
Bend Dimensions
Radius—Adds a bend to the attachment edge according to a specified value. Default values are as follows:
Thickness—Uses a radius equal to the thickness of the sheet metal wall.
2.0 * Thickness—Uses a radius equal to twice the thickness of the sheet metal wall.
[<Parameter Value>]—Uses a radius as set by the SMT_DFLT_BEND_RADIUS parameter.
Dimension Location buttons:
—Dimensions the radius according to the outside surface of the wall.
—Dimensions the radius according to the inside surface of the wall.
—Dimensions the radius as set by the SMT_DFLT_RADIUS_SIDE parameter.
Wall Angle list—Lists predefined values, user-defined values, a flat wall option, and [<Parameter Value>] for the wall attachment angle.
* 
[<Parameter Value>] uses an angle set by the SMT_DFLT_BEND_ANGLE parameter.
The angle between the attachment edge and surface cannot exceed 180 degrees. When you need a larger angle, use the opposite side of the sheet metal as the attachment edge.
—Flips wall orientation along the attachment edge. When you flip the angle of a sketch, the wall is mirrored about a plane to keep the symmetry.
* 
To make the command available on the Flat tab and shortcut menu, set the smt_allow_flip_sketch configuration option to yes.

Overlap—Creates a standard overlapping edge rip.
Flip—Reverses the overlap direction.
Add Gap—Adds a space between the edges by a specified value.
[<Parameter Value>]—Creates a rip whose type is controlled by the SMT_DFLT_EDGE_TREA_TYPE parameter.
* 
You can set the seam type and any required dimensions for Gap, Blind, and Overlap in the Seam area of the Sheetmetal Preferences dialog box or in the Parameters dialog box.
Miter Cuts—Adds miter cuts between a pair of wall segments with overlapping geometry.
Click the Add miter cuts check box to set the following options:
Offset Value—Offsets the miter cut between the two adjacent edges.
