What’s included

Spline Cleaner
Clean, repair and organize thousands of splines in seconds. The essential tool for anyone working with CAD imports or vector curves.

Spline Combiner
Perform boolean operations between shapes, cut splines into parts, and manage curve intersections with precision.

Spline Refiner
Subdivide your splines uniformly without losing any detail, generating even segmentation across hundreds of curves in one click.

SubSpline
Select and manage spline subobjects and material IDs with advanced tools that go far beyond 3ds Max’s native capabilities.

Spline Data
Get instant, real-time information about every spline in your scene: shape count, curve length, open/closed status, vertex data, and more.
A complete pipeline, not just a collection of tools
Each plugin in this toolkit was designed to cover a specific stage of spline-based work in 3ds Max. Together, they form a seamless pipeline:
1. Import & diagnose — Open Spline Data and get an instant picture of everything in your scene: how many shapes, curves, vertices, open/closed splines, hidden duplicates, and potential extrusion errors.
2. Clean & repair — Run Spline Cleaner on your imported CAD or vector data. Remove duplicates, weld overlapping vertices, flatten splines, apply batch operations across hundreds of shapes simultaneously, and get error reports in seconds.
3. Edit & combine — Use Spline Combiner to perform union, subtraction, and intersection boolean operations between shapes — just like in a vector editor. Cut shapes with the Shape Cutter tool, detect and handle spline intersections, and break complex shapes into manageable parts.
4. Refine & subdivide — Before extruding or using your splines in procedural workflows, run Spline Refiner to equalize the segment distribution across all your curves. Get smooth, even geometry that behaves correctly under modifiers and extrusions.
5. Control subobjects & material IDs — SubSpline gives you advanced tools for selecting vertices, segments and curves at subobject level, and lets you precisely control material ID assignments across all your shapes — essential for procedural modeling with RailClone and similar plugins.
Who is this toolkit for?
This bundle is the right choice if you regularly work with any of the following in 3ds Max:
- CAD, DWG or DXF imports that need cleanup before modeling
- Illustrator or SVG vector curves converted to splines
- Architectural floor plans and terrain contour lines
- 3D logos, text-based shapes, or decorative elements
- Procedural modeling workflows using RailClone or similar tools
- Any project that involves extruding, sweeping, or lofting splines into 3D geometry
It is ideal for professionals in Architectural Visualization, Industrial Design, 3D Modeling, Motion Graphics, CG Animation, Game Art, and Graphic Design.
What our users say
Kirsten (verified owner – Spline Cleaner)
“I’ve been bringing in hundreds of complex shapes as Illustrator files, unwieldy and riddled with overlapping vertices. This script allowed me to attach all, check errors, optimize, weld, and even make renderable in seconds. Having all those tools in one place is great.”
Uwe (verified owner – Spline Cleaner)
“We work with massive amounts of imported CAD data and always had to spend hours cleaning up splines. With this plugin it’s a breeze. Finding and welding open splines now takes just a few clicks. If you work a lot with splines and want a less time-consuming workflow, I truly recommend it.”
Dragan (verified owner – SubSpline)
“I find it very useful, especially for preparing splines for RailClone. Displaying material IDs helps a lot for organizing segments, and the Reverse IDs and Pattern tools are a life saver. For RailClone users, SubSpline is a must-have.”
