Copy Objects Along Any Path with NT Array
NT Array is a free SketchUp array plugin created by Nice Tower for copying groups and components along straight lines, curves and custom paths. Control the distribution of repeated objects to build railings, façade elements, lights, landscape assets and architectural details faster.
Replace repetitive copying with a controlled SketchUp array
Manually copying, rotating and spacing every component can slow down even a simple model. NT Array turns that repeated process into one focused command: select the source component, choose the path and control how copies are distributed. The video below shows how the plugin simplifies a copy-along-path task while keeping placement clear and predictable.
A practical SketchUp array plugin for precise repeated geometry
Architectural models often contain repeating components such as balusters, lights, panels, chairs, trees and façade modules. NT Array helps architects, interior designers and 3D artists distribute these objects along straight, curved or custom paths without placing every copy manually. It reduces repetitive modeling and gives you a faster way to test spacing, quantity and visual rhythm.
Copy along curves
Distribute components along arcs, splines and custom SketchUp paths with consistent control.
Straight arrays
Create organized rows of repeated objects for interiors, façades and construction details.
Count control
Adjust the number of copies to compare different densities without rebuilding the complete array.
Spacing control
Set practical intervals between repeated components and refine the rhythm of the design.
Component workflow
Work with grouped objects and components while keeping the original model organized and editable.
Free RBZ installer
Install NT Array through SketchUp Extension Manager and use the plugin at no cost.
How to copy components along a path in SketchUp
Prepare one clean source component and a continuous guide path before starting. Keeping the object axis and path direction clear makes the resulting SketchUp array easier to control and edit.
Select the object
Choose the group or component that should be repeated throughout the array.
Choose the path
Select a straight line, curve or connected path that defines the distribution.
Set count or spacing
Control the number of copies or the interval between repeated objects.
Review the array
Inspect alignment and density, then adjust the setup when the design needs refinement.
Build curved repetitions without placing every object by hand
NT Array is especially useful when repeated elements must follow a changing direction. The plugin handles the distribution along the guide path, allowing you to focus on the design instead of measuring, rotating and relocating each copy. This second example demonstrates how a path-based array makes detailed SketchUp modeling significantly quicker.
Create repeated architectural elements faster
Railings and balusters
Distribute posts and balusters along straight stairs, balconies and curved railing paths.
Façade systems
Repeat panels, fins, louvers and modular components across architectural elevations.
Interior layouts
Arrange lights, seats, shelves and decorative elements with consistent spacing.
Landscape models
Place trees, bollards, lights and site components along walkways and custom curves.

More tools and training for better SketchUp results
Combine NT Array with professional SketchUp training, AI-assisted modeling and advanced extensions to build faster architectural workflows. For geometry that must bend along a curve before repetition, explore the NT FlexPath plugin. When an object needs direct axis-based deformation, use the NT Axis Bend plugin.
NT Array FAQ
Is NT Array free?
Yes. NT Array version 1.0.0 is available as a free RBZ download from Nice Tower.
What can I copy with NT Array?
You can distribute SketchUp groups and components such as balusters, panels, lights, furniture, trees and other repeated objects.
Can NT Array copy objects along curves?
Yes. The plugin supports distribution along straight lines, curves and connected custom paths.
Should the source object be a component?
A clean group or component is recommended because it protects surrounding geometry and keeps repeated objects easy to manage.
How do I install the plugin?
Download the RBZ file, open SketchUp Extension Manager, choose Install Extension and select the NT Array file.
