Bracket Toe 3

Fixed:

TOE_H, R_ANG [,TOE_L, RAD]

Given:

LENGTH [,RAD, TOE_L]

There are three different cases for the evaluation of this toe:

1.

The normal situation is that TOE_L is controlled via the bracket set-up (or sometimes evaluated automatically by the modelling). Then RAD is calculated from R_ANG and TOE_L.

2.

Another option is that RAD is given, either in the bracket setup or by the user. Then TOE_L is calculated from R_ANG and RAD.

3.

All of R_ANG, TOE_L and RAD are given (in bracket set-up and/or by the designer). Then the toe is over-determined. The following will happen:

• R_ANG will be re-calculated. If the calculated angle is bigger than the value from the bracket set-up the new value will be accepted.

• If the calculated value is smaller (for example, because the given RAD is small in relation to TOE_L) then a line segment will be inserted in the direction of the original value of R_ANG from the top of the toe to the beginning of the arc. This case is illustrated by the dashed contour above. In the other cases the result will be as in the solid contour.

Other remarks

1.

The toe is always perpendicular to the bracket arm.

2.

Normally, this bracket toe should not be used in combination with a folded flange.
