| Fixed grid
|
Used to sets fixed grid for the approximate distance
of the purlins within the area between first and last purlin. The program
divides the distances regularly according to this specification and the value
is rounded up or down correspondingly.
- Grid – When
checked, a fixed grid is set for the distance between the purlin.
- Pattern
effective – Displays the grid pattern value as actual distance
effective for grid settings.
- Maximum
value – Enabled for Grid. When checked, the grid value only be
fitted to smaller values.

| Free grid
|
Enabled when
Grid is unchecked. The
Free grid can freely define the grid division
within the area between the first and last purlin.
- Distance – Sets
distance between the first and last purlin, selected from available list, or
enter a new value. You can vary the number and the distance, as required.
- Turn – When
checked, inverts the distances used.
|
| Offset bottom
|
Sets the distance from the centerline of the lowest
purlin to the outer edge of the selected area.
|
| Offset top
|
Sets the distance from the centerline of the topmost
purlin to the outer edge of the selected area.
|
| Fix
|
Offset fixed - enabled for fixed
Grid. If one of these options is checked, the
selected distances are also kept in the grid; otherwise they are centered.
|
| Offset Left
|
Sets the purlin projection extending past the
left outer edge of the selected area. In case of a
diagonal edge, this value references the centerline of the purlin; negative
values shorten the purlin towards the inside.
|
| Offset Right
|
Sets the purlin projection extending past the
right outer edge of the selected area. In case of
a diagonal edge, this value references the centerline of the purlin; negative
values shorten the purlin towards the inside.
