Flange

This command adds a linear part to a sheet part utilizing the length of one of its edges..

Creation stages / Use:

Click the icon or select Sheet Metal > Flange... from the drop-down menu.

Select the flange edge

	Click yellow handles for a rapid and dynamic modification of the length and the angle of your flange.
	Double-click the labels to enter the length and angle values of the flange.

(several edges can be selected to create several identical flanges).

Enter the bend parameters (inner radius, angle, position).
Enter the length of the flange.
Enter the width of the flange.
Indicate the parameters of the notches.
Validate the creation of the flange with the button.

	Click yellow handles for a rapid and dynamic modification of the length and the angle of your flange.
	Double-click the labels to enter the length and angle values of the flange.

Available Options:

Bends:

This section allows you to define the bend parameters:

the position in relation to the edge selected.

	Bend upon edge: The flange is offset form the selected edge. The distance is the bend radius.
	Thickness upon edge: The inner face of the flange is coincident with the selected edge.
	Thickness below edge: The outer face of the flange is coincident with the selected edge.

the bend radius calculation mode:

	Manual: Enter the inner bend radius.
	Thickness: The inner bend radius is the thickness.
	Unfolding rule: The inner bend radius is defined by an unfolding rule regarding the thickness and the material.

the bend angle
the additional length:

Basic sheet without flange	Flange with a null additional height (bend upon edge)	Flange with an additional height (bend upon edge)

When the reference face of the flange (face used to calculate the angle) is cylindrical, the Thickness on the edge mode and Thickness under the edge are not functional.

Length:

	This section defines the length of the flange: Select the mode for calculating the length:
	Enter the value of the length of the flange.
	Tangent length: The length is calculated in relation to the tangent to the bend radius.
	External length: The length is calculated in relation to the external face connected to the flange.
	Internal length: The length is calculated in relation to the tangent of the inner bend radius.
	Linear part length: The length is calculated on the plane part of the flange.
	Enter the flange offset value if needed. This offset is the distance between the entered length and the real length of the bend. For example if the bound is defined as plane and if a plane is selected, the offset will be the distance between this plane and the bound of the bend.

Width:

Notches:

Advanced options:

When the flange is made on several edges, you can indicate a gap for the auto-trim of the flange:

This gap corresponds to the width of the slot where the flanges should intersect.

By activating the Create sketch option, TopSolid creates a sketch (rectangular) for each flange, you can then modify the shape of the flange by editing the corresponding sketch.

Modifications / Additional information:

When the flange is created, a double click on one face of the flange displays the main driver dimensions (length, angle, inner radius, width, etc.).
