'Cross bars 1' / 'General' tab
'Bottom / top cross bars 1' configuration entry

Rounding:

Rounding of cross bar lengths:

Don't: no rounding of bar lengths.

Exact: 1-4 = rounded down, 5-9 = rounded up

Round up: bars are rounded up to the value given in "Rounding value".

Round down: bars are rounded down to the value given in "Rounding value".

Rounding value:

[m] The lengths are rounded to this value.

Minimum length:

[m] Shorter cross bar lengths are omitted.

Cut with recesses:

[m] Minimum length / Minimum width

If a recess is smaller than the value entered, then the cross bars are not cut with the recess.

'Cross bars 2' / 'Layers' tab
'Bottom / top cross bars 2' configuration entry

The following parameters area available for bars in the 1st and 2nd layers:

Bending shape is:

invalid / valid

A bending shape defined at an edge can be used or removed from the cross bars in the appropriate layer. (Be careful with sloping edges: the bending shape, which is usually applied there, will automatically be used for cross bars, too!!)

Bar overlap:

as entered: the overlap defined for an edge is used. The following fixed value is used if the bar overlap is zero.

use SetValue: regardless of the overlap defined for the edge, the following fixed value is used unless manual entry produces a useful shortening value.

SetValue (bar overlap = 0):

[m] Fixed value for bar overlap at panel edges. This value is used even if the bar overlap is zero.

Bar overlap at recesses:

[m] Fixed value for bar overlap at recess edges. This value is only used if neither the smart fixture symbol nor the manual entry produces a useful value.

Bar overlap > 0 at inclined edges:

as if bar overlap = 0: cross bars are treated as if the overlap was zero:

max. bar length: the cross bars at the inclined edges are given the bar overlap entered but they are not to exceed the entered maximum bar length.

normal: cross bars at inclined edges are treated like those at normal edges.

Maximum bar length:

[m] Value for the above setting.
