Structure Builder

Deprecated

Structure Builder is deprecated. Use the Shape Builder's Line shape (or Curve for curved runs) with a part template instead — it builds the same walls from Height & Width, plus point editing, spacing, extra corner types, and closable loops. Structure Builder keeps working for now, but new features land in the Shape Builder.

What it is ℹ️​

Generate repeated or patterned structures like walls, fences, posts, or grids from simple inputs.

Problems it solves 🧩​

  • Spending too long laying out repeated parts one-by-one
  • Inconsistent spacing and misaligned endpoints on corners
  • Hand-building round or beveled corners for long runs
  • Gaps at corners when elements meet at odd angles
  • Rework from destructive edits when experimenting with layouts

When to use 🧭​

  • Laying out long runs of repeated parts (walls, fences, rails, curbs)
  • Building paths/roads/sidewalks with smooth round/bevel/touch/fill corners
  • Keeping exact spacing and clean endpoints without gaps or overlap
  • Placing rows or grids of posts, lights, tiles, or floor panels
  • Conforming placement to surfaces or offsetting above them
  • Reusing a template part to copy materials and properties across the run
  • Iterating quickly with non-destructive previews and undo/redo
  • Optionally unioning on finish to reduce part count

Panels 🎛️​

Corner Settings ➰​

Structure Corner Settings

Note: Corner Mode is applied when adding a new part. No live preview.

Corner Mode Round​

  • Wedges: Uses wedges when generating a round corner

    • Segments: Number of segments to add. Default 60 for a full circle. For a 90° corner, it uses one quarter of that (15). Setting it to 1 behaves like Corner Mode Bevel.

    Structure Corner Round

  • Cylinder: Uses a cylinder to add a round corner. Less accurate in some conditions, but corners are smoother.

Corner Mode Fill: Extends parts so the farthest corners connect​

Corner Mode Touch: Shrinks parts so the closest corners are touching.​

Corner Mode None: Centers are touching​

Tips 💡​

  • Use "Alternating Offset" from Finalization Settings to avoid texture Z‑fighting if not unioning the final result.
