Create industrial interiors, rooftops, utility rooms, factories, service corridors and mechanical environments without modeling every duct fitting from scratch.

This original modular pack includes 54 coordinated assets: 18 rectangular ducts with straights, 45/90-degree elbows, T/Y/cross junctions, reducers, offsets and round-to-rectangular transitions; 16 round ducts with straights, 45/90-degree elbows, T/Y/cross junctions, reducers and offsets; 8 fans, dampers and vents; and 12 hangers, flanges, clamps, supports and connectors.

Every asset is supplied as a separate editable mesh and as part of the full catalog. Connector A is located at the asset's local origin. Connector positions follow a 0.5 m modular grid, with 1.0 m as the secondary grid. Nominal connector profiles, sizes, positions and directions are documented in the included CSV manifests.

Technical details:

• 54 individual files in each format

• Six editable embedded PBR materials
• Non-overlapping UVs on every asset
• No external texture files required
• Clean asset IDs and four organized Blender collections
• Asset manifest, connector manifest, technical summary and README included
• Intended for games, architectural visualization, animation, VR/AR and digital environments

This is a visual 3D asset pack. It is not engineering-certified and is not a substitute for HVAC calculations or fabrication drawings. It is not intended for physical 3D printing.

The product contains original procedural geometry and no third-party logos or trademarked designs. It was created with an AI-assisted procedural workflow and reviewed with geometry, snap-grid, package and format round-trip validation.

Compatibility and editing: the native BLEND scene was reopened in Blender 5.1.2 and contains 54 separate editable mesh objects, not one combined element. It has applied unit scale and rotation, zero remaining modifiers, six embedded materials, no linked libraries and no external image textures to relink. The download also includes 54 individual BLEND, FBX, OBJ/MTL and GLB asset files.
