Description Name
Vertical Grid Pattern
NOTE These parameter descriptions apply to the Horizontal Grid Pattern instance parameters also.
If Layout (under Vertical Grid Pattern) is set to Fixed Number, enter the
number of curtain grids for the curtain instance. The maximum value is
200. Number
Determines the spacing of grids along the curtain element face, when
grid spacing does not divide evenly into the face length value. Justification Justification
also determines which grid lines are first removed or added when the
number of grid lines changes because of parameter changes or changes
to the size of the face.
Beginning adds space to the end of the face before
placing the first grid. Center adds an even amount of space at both the
beginning and end of the face. End adds space from the beginning of
the face before placing the first grid.
Rotates the curtain grids to the specified angle. If you specify this value
for individual faces, no value is displayed in this field. Valid values are
between 89 and –89. Angle
Starts grid placement at the specified distance from the justification point
of the grids. For example, if Justification is specified as Beginning and you Offset
enter 5’ for offset, the first grid is placed 5‘ from the beginning of the
face. If you specify offset for a face, no value is displayed in this field.
An imaginary line that defines the point from which to measure grid spa-
cing on faces where grid spacing may not be the same across the length Measurement Line (curtain system only)
of grid lines. Where grids intersect this line, the distance between the grids
is equal to the grid spacing value (for Fixed Distance layouts) or up to the
grid spacing value (for Maximum Spacing layouts). Where the grids do
not intersect this line, the grids can be placed at values either higher or
lower than the value for Spacing.
