- The document discusses 3D modeling of adaptable families for construction sites, including brackets, stairs, and railings. - For the bracket family, the modeling follows brand specifications and allows for different end configurations and lengths. - The stairs families include basement, middle, and head units with options for railings, heights, and inclinations. Modeling follows brand documentation. - The stairs families are designed to adapt based on number of steps and lengths while following technical constraints.

2. 3D modeling of an adaptable family of brackets
(Outinord)
Mains characteristics:
• Attract by walls for an easy and intuitive drawing,
• 3D modeling following the brand of the bracket for the best
accuracy (real measurement),
• Choices for the end of the bracket: railing or not, strait, 90
degree, 45 degree,...
• Extraction of data possibles.
Complex bracket path with different kind of extension (straight with and without
railing, 90 degree without railing). Simple bracket with two straight extension and railing.
Bracket vith a left straight extension (without railing) and a right angle extension
(with railing).

3. 3D modeling of an adaptable family of stairs (Escalib, Mills)
Mains characteristics:
• 3D modeling following the brand of the stair and its characteristics,
• Composed of 3 elements: the basement, the middle element and the head of the stair,
• Different choices available for each element for the railing (opening or not..),
• Extraction of data possibles.
Middle element of the construction site stairs, with all elements possible (the drafter has to
chose which one to keep.) Example of a possible staircase.
Adaptable height of the feet
Railing removable
Inclined railing
If necessary, module closing
the stair
Basement unit
Middle unit
Head unit

4. 3D modeling of an adaptable family of stairs (Harsco)
Mains characteristics:
• 3D modeling following the characteristics of the stairs (Harsco documentation),
• Attract by the two floors on which the stair will lay for an easy and intuitive drawing,
• Options: number of step and total length following the first choice,
• Possibility of data extraction.
Stairs adaptation example: same number of steps, hight and length changing.
