Modular builder suite

Modular Builder Suite is an Editor only Unity extension for designing, generating, and managing scalable windows and walls, no coding required. Sketch layouts quickly with clicks, or type exact lengths/angles when you want precision.

Three ways to work

1) Parametric Window Generator
Enter width, height, columns, rows, and mark each opening Fixed or Sash. Click Generate to create a complete window assembly (frame rubbers, glass, and auto-placed handle).

2) Measurement Mode (fit to an existing opening)
Model walls/openings however you like. In Measure Mode, click the four sides (inside faces) of an opening; the tool builds a window exactly to that opening and centers it to the wall’s thickness.

Requires colliders on the opening’s geometry.

3) Blueprint Mode (Beta)
Import a floor-plan image, trace walls by clicking each corner (clockwise or anti-clockwise), then trace where windows go. Click Generate to build walls, cut openings, and place the windows. After generation, a Window List appears in the Inspector for bulk edits (heights, names, settings).

Core features

• Click-to-trace walls, with optional typed lengths/angles for precision.
• Per-opening Fixed vs Sash, rows/columns, dimensions, and mullion setup.
• Material persistence: frame/glass materials remembered between sessions.
• Inspector list for batch tweaks and prefab save/update.
• Clean, edit-mode workflow. No runtime building layer.

Doors (current): Not yet included. Workaround—set sill height = 0 for a door-height opening; generate; then delete the window to leave the opening.
