Flange Dialog Box - Main Area

Alignment

The basic flange direction runs

in normal direction of the base surface, if surface edges have been selected as guide curve, or
in normal direction of the target surface, if the guide curve is a curve segment or curve.

Shell normal: The basic flange direction runs in direction of the normals in each point of the guide on the selected surface.; If the guide does not lie on the surface, it is projected normal onto the surface, and the normals in the projected points define the basic flange direction.
Guide + prio. tangent: The basic flange direction is generated from a moving frame type that is aligned by the normal plane in each point of the curve and by the direction defined in the Orientation box. The moving frame type runs tangentially to the guide and thus may define a different flange direction in each curve point.
Guide + prio. direction: Defines the basic flange direction by a moving frame which is only aligned by the direction specified in the Orientation box without taking into account the curve tangent or normal plane. The basic flange direction is equal in each curve point.
Moving frame: Defines the flange direction by a moving frame (see Moving Frame tab).

Guide

Selects one or several guides. Following elements can be selected:

A simple curve. All curve types are allowed.
A curve connected to a surface, e. g. Isoparametric curves or Curve on surface.
A surface edge.

Surface

These options are only available for Shell normal.

Selects one or several surfaces or planes, whose normals specify the basic flange direction in the points of the guide.

Basic surface: If a guide is projected onto a face selected as support and the result lies in the trimmed area of the face, the flange will not be completely computed along the guide.; If Basic surface is selected, the guide is projected onto the basic surface of the faces.; If Basic surface is cleared, the guide is projected directly onto the selected faces.; Note: The projection of the guide onto the underlying surfaces of faces is only possible in case of support surfaces being selected with Surface for Shell normal, but not onto faces selected as target surfaces with Target on the Advanced tab.

More Info

Displays deviations and output results.

Display

Displays values in the work area.

U+V

Displays the UV vectors of curves and surfaces.

MFT

Displays the local coordinate system for the moving frame type.

Corner

The display of the Corner manipulators can be selected and off.

Invert

The display of the manipulators for inverting the direction of individual wires in the selection of guide curves can be switched on and off.

If the selection of the guide curve includes several wires, the direction of the individual wires influences the result calculation.

The invert manipulators indicate the intrinsic wire flow direction of the selected wires and allow to invert the direction of individual wires in order to obtain an optimal result.

Apply Modes

Defines the update mode of the active feature while editing it.

Dynamic: Feature update occurs dynamically when moving handles or editing parameter values by sliders in the dialog box.; This option is not available for each command.
Static: Feature update occurs only after releasing the handle.
Preview: Displays a preview when geometry is modified by means of the handle and LMB pressed. The original geometry remains unchanged. Feature update occurs only after releasing the LMB.; This option is not available for each command.
None: Feature update occurs only after selecting Apply.

Deviation

Guide: Displays the deviation of the approximated guide.
Shape: Displays the deviation from the flange.

Output Result

Max. order: Indicates the maximum order of the result created in both U and V.
Max. segments per cell: Indicates the maximum number of segments created in U and V direction.
No. of cells: Indicates the number of cells created in the result.

Manipulators and Contextual Commands

The created flange surface can be modified as follows using the manipulators:

Moving the drag manipulator on the guide, you can add additional manipulators allowing to specify individual lengths and angles:

The flange surface can be restricted to a partial region:

Pressing the control key allows simultaneous manipulations of length and angle. In this case, however, individual values will be equated.

At the manipulator handles, right-click to activate contextual commands with the following options:

Edit: Modifies the parameter value in the dialog box Tuner.
Keep this point: (for angle modification only); Creates a point at the current position of the manipulator.
Spread all: (for angle and length modification only); Assigns the current value to all other manipulators.
Delete: (for additionally inserted manipulators only); Deletes the manipulator.
Invert: Inverts direction or angle. Corresponds to Invert direction/angle for Length and Angle.
