The selected support is to be used for the creation
of the surfacic flange.
By default, this option is selected.
Approximation
The support surface is approximated
using a ruled surface. This ruled surface is defined from two curves:
The OML (in light blue), computed at the intersection between
the support surface and the web plane.
A curve parallel to the OML (in pink),
computed at a distance equal to the approximation length.
This mode enables you to compute the maximum deviation between the
support geometry and the approximated surface.
Angle
The support of the surfacic flange can also be defined by a line, a curve, an angle,
or the edge of a base feature. The angle is constant and you can change its value using
the spinners.
Vector Directions
Invert material side
Shows on which side of the support surface the surfacic flange is built.
Surfacic flange
Shows the part of the support surface that is kept according to the base feature.
Base feature
Shows the part of the base feature that is kept according to the support surface.
Note:
Surfaces or curves used to define the support
surface must be continuous in point and tangency.
EOP
Length From OML
Length between the curve defining the top of the surfacic flange and the OML (Outer Mold Line).
By default, this option is selected.
Element FD
Boundary folded element, either a surface that intersects with its surface, or a sketch, or a wire projected on its surface.
Element FP
Curve or sketch defining the flattened profile of the surfacic flange.
Sides
Standard
The sides are automatically defined at the web limit
and the perpendicular planes are kept.
By default, this option is selected.
Surfacic Flange defined by Side 1 and 2 as Standard
Element FD
The sides are defined by a folded geometric element (curve, plane, profile, or
surface). Surfacic Flange defined by Side 1 and Side 2 as Element FD (in light
brown).
Element FP
The sides are defined by a flattened geometric element (curve, plane, profile,
or surface), showing a flattened profile of the flange. Surfacic Flange defined by the EOP as Element FP (in light blue) and Side
1 and Side 2 as Element FP (in light brown) Unfolded view of a Surfacic Flange defined by the EOP as Element FP (in
light blue) and Side 1 and Side 2 as Element FP (in light brown)
None
The sides are not computed, only the EOP defines the profile of the flange.Surfacic Flange defined by the EOP as Element FD, and Side 1 and 2 as None
If you do not define a surfacic flange
side, the latter is automatically computed at the web limit, perpendicular to the
OML.
If no corner is defined, the side and
the EOP relimit each other.
The sides of the fillet are continuous
in tangency with the profile of the web and the sides of the surfacic flange.
If you create a surfacic flange on a
closed or curved surface, the sides and corners are automatically specified to
None.
Corners
None
No corner is computed, only the EOP is able to define the profile of the surfacic flange.
By default, this option is selected.
Corner
A corner is created between the side and the EOP (defined with a radius value).Surfacic Flange defined with Sides 1 and 2 as Standard, and Corners 1 and 2 of
10mm each.
Note:
If you create a surfacic flange on a closed or curved surface,
the corners are automatically specified to None.
Process
This topic provides information about the manufacturing process and the K factor.
Hydropressed
By default, this option is selected.
BrakeFormed
By default, this option is cleared.
Refined Unfolded View
This option lets you fold or unfold more precisely a surfacic flange on a support with a
joggle.
By default, this option is selected.
Compensations
None
No compensation is applied.
By default, this option is selected.
Automatic
For symmetric flanges, A1=A2, so that the length of the flatten EOP = length of the folded
EOP.
Manual: Angle
The deformation is computed according
to an angle.
Manual: Length
The deformation is computed according
to a length parallel to the BTL.
Note:
In case of a Manual:
Angle compensation, you need to define the Angle compensation. A negative angle adds material, and a
positive angle removes material.
In case of a Manual:
Length compensation, you need to define the Length.
Important:
Compensations can be created either on the folded or flattened part, but they only apply on the flattened part.
Compensations can be modified independently on each flange.
The + sign (in yellow in the work area) shows that material is added to the sides.
The standard files and compensations and runout must be previously defined from the
SheetMetal Parameters Definition dialog box to have access to the
Apply Compensation option.
By default, this option is selected.
