One modifier, finished structure

Edit the mesh, everything follows

Move a vertex, extrude an edge, cut a hole. Every beam, column, post and grating bar is rebuilt from the floor plan instantly, so layout changes cost seconds instead of a remodel.

Every part on its own switch

Start with deck and frame, then add supports, bracing, railing and toe boards. The same mesh gives a hanging platform, a mezzanine or a full structure on columns.

Columns that find the ground

Pick any ground object and every column grows down until it hits it, uneven terrain included. At the foot of a stair the frame simply rests on the ground.

Six real steel sections

I-Beam, T-Beam, U-Channel, L-Angle, Flat Bar and Round Bar, built parametrically with rounded roots and edges. Frame, columns and braces each get their own section and sizes.

Stairs from sloped faces

Mark the edges of a sloped face and it becomes a stair with grating treads. All risers are equal and the top step is flush with the deck, whatever the height.

Railing that follows every corner

Posts, handrail and knee rails with rounded corners sit just outside the frame. Open sides stay open, rail ends stop cleanly before them.

Real bar grating

Bearing bars, cross bars and a binding bar along every edge, as actual geometry with UVs. Openings and height changes get clean edges.
