In the first step, the automation tool creates the analytical elements for the selected structural physical objects. The created analytical model follows the engineering mind set through rule-based automation logic. The objects are aligned to project grids and levels.
These rules are applied automatically and you can adjust their settings using their parameters. These rules are analyzing the selection globally.
The selected structural physical model is analyzed by the automation tool to identify each dominant direction.
For each dominant direction, the selected structural elements are grouped based on their relative offsets.
For each identified group, a virtual grid is calculated. This virtual grid will be used as a vertical alignment reference to which all the elements in the group will be aligned in plane.
If a model grid is overlapping with this group, it will be considered the vertical reference to which all the elements of the group will be aligned in plane.
Once elements are projected to the nearest virtual grid, their ends are aligned to the intersection of the virtual grids found within the calculated tolerance.
For the alignment on vertical, each model element is looking for a level within a tolerance. If a level is found within this tolerance, the analytical representation for this element is aligned to that level.
This tolerance can be multiplied by a factor present in the automation tool settings for each type of object.
If more levels are identified within the tolerance of the element, the level assigned to most of the elements will be the alignment level for all.
If you want to specify the level to which the elements will be aligned to, check the "Structural" parameter in the level properties.
The inclined planes are calculated virtual references, they are determined when the automation tool identifies a slanted rafter with an angle to the horizontal of less than 35 degrees.
The analytical representation of this rafter and all the analytical elements that have physical counterparts in contact with this rafter, will be aligned to this plane.
