scafold system to construct destructable bridges walls objects buildings

consist of only 3 building parts [collission A]
1 a square side beam (orange) [does not collide with itself]
2 a diagonal beam (orange) [does not collide with itself]
3 a steel nut (red)

they match on the grid each square element is 1m x 1m

to change the construction strenght , select all red nuts and change their density

the small dot like shapes in beams is to easy select a part to copy / drag / delete

when a beam breaks loose, simply delete it and place a new one in pause,
or in play but then place it on correct position

the connecting beam is very thin to reduce weight
