Generate spiral, dog-leg, or standard stairs just by entering your dimensions. v2 even adds options for landing "waiting steps".

By evening, the warehouse felt less like a problem and more like a solution in progress—efficiently modeled, clearly documented, and ready for the next round of design decisions.

He began with the envelope. Using the “Wall” tool, Alex clicked the warehouse perimeter and dragged a wall thickness of 300 mm. The tool instantly generated a clean, grouped wall with separate faces for inner and outer skins—proper geometry for later section cuts and material assignment. The plugin respected SketchUp layers and group structure, so he could toggle visibility for structural versus finished faces without extra cleanup.

1001bit Pro v2 for SketchUp is a comprehensive set of parametric architectural modeling tools designed to automate the creation of complex building elements. By inputting specific parameters like dimensions and materials, users can instantly generate accurate 3D models of stairs, walls, windows, and roofs, significantly reducing manual modeling time.

The license is a "perpetual license," meaning you pay once and own it forever. As of this writing:

One of 1001bit Tool Pro v2’s strengths was parametric control. Alex realized the loft layouts could benefit from a slight change in floor-to-floor heights to accommodate mechanical runs. He opened the tool’s parameter manager, adjusted the mezzanine elevation by 250 mm, and watched as stairs, railings, and window sill heights updated in sync. No manual recalculation, no messy edits—just intent-driven changes.
