DRH Add-ons Hub

DRH - Object Layout Studio helps Blender users align, distribute, arrange, move, rotate, orient, register, ground, quantize, and position objects through repeatable layout and geometry-aware workflows.

Complete and Lite are available through BlendKit.

This repository is the central public hub for support, documentation, issue tracking, compatibility feedback, and release notes for both editions.

Support DRH Development

If DRH - Object Layout Studio helps you work faster or makes your Blender workflow more reliable, you can support ongoing DRH development on Ko-fi. Your contribution helps fund maintenance, Blender compatibility updates, documentation, testing, and the development of new production-focused tools across the DRH ecosystem. Support is completely optional, and bug reports, compatibility feedback, and workflow suggestions are always welcome.

Overview

DRH - Object Layout Studio is a Blender workflow utility designed to make object alignment, distribution, arrangement, transform matching, geometric alignment, registration, and precision placement faster and more repeatable.

The product is available in two editions:

  • Complete - DRH - Object Layout Studio: Align, Transform, Advanced, and Utility.
  • Lite - DRH - Object Layout Studio Lite: Align and Transform only.

The editions use separate extension IDs and can be installed independently. When Complete and Lite are enabled at the same time, both editions display a warning that the Complete edition is active and recommend disabling Lite to avoid duplicate tools.

Editions

Both editions have released 1.0.0 listings on BlendKit. The support repository remains shared so documentation, issue tracking, compatibility information, and release notes stay in one place.

What DRH - Object Layout Studio does

DRH - Object Layout Studio helps you position and organize objects using explicit alignment, bounds, spacing, transform, view, geometry, registration, and surface rules.

It is designed for scene-layout and geometry workflows where repeatable object relationships matter more than manually adjusting each transform one object at a time.

Use it to:

  • Align objects by origin or evaluated bounds.
  • Align selected objects to the active object.
  • Distribute objects by equal centers or true equal gaps.
  • Arrange objects in 1D and 2D layouts.
  • Move and rotate objects by exact values in local or world space.
  • Match location, rotation, scale, and supported dimensions from the active object.
  • Align objects relative to the current viewport.
  • Auto-orient objects from mesh geometry.
  • Align Point, Line, and Plane features.
  • Register source and target geometry using captured point pairs.
  • Refine object alignment with best-fit / ICP workflows.
  • Drop selected objects onto an active mesh surface.
  • Center, ground, quantize, and refine object origins.
  • Use the Lite edition when only Align and Transform workflows are needed.

Key features

  • Precision origin and evaluated-bounds alignment.
  • Active, selection, cursor, and world references.
  • Equal-center and equal-gap distribution.
  • Grid, line, circle, and arc arrangement workflows.
  • Local and world transform controls.
  • View-aware alignment and distribution.
  • Geometry-driven Auto Orient.
  • Point / Line / Plane feature alignment.
  • Point-pair registration and best-fit refinement.
  • Surface placement and grounding.
  • Mesh Edit alignment helpers.
  • Center & Ground and Transform Quantize.
  • Configurable Sidebar Tab and Panel Title.
  • Collapsible subgroup workflow.
  • Object context-menu integration.
  • Complete and Lite editions using one shared support repository.

Feedback and compatibility reports

This repository remains open for public feedback for both released editions.

Feedback is especially useful for:

  • Alignment accuracy.
  • Origin and bounds behavior.
  • Distribution ordering.
  • Equal-center and equal-gap workflows.
  • Grid, line, circle, and arc arrangements.
  • Move and Rotate workflows.
  • View Align behavior.
  • Auto Orient results.
  • Point / Line / Plane feature alignment.
  • Registration and best-fit behavior.
  • Surface placement.
  • High-density mesh performance.
  • Complete vs Lite workflow expectations.
  • Installation experience.
  • Compatibility concerns.
  • Documentation clarity.
  • BlendKit delivery or listing issues after release.

Useful feedback examples:

“Equal Gaps should preserve this object ordering rule.”

“View Align behaves differently in this viewport orientation.”

“Auto Orient should prioritize this axis for this type of mesh.”

“The Lite edition should keep this Align workflow.”

“Best Fit takes too long on this mesh density.”
