For 3ds Max users handling complex, spline-heavy projects, Spline Cleaner is an essential plugin that optimizes your workflow, automates repetitive tasks, and prepares your splines for accurate extrusions. Ideal for architectural plans, CAD file imports, and Illustrator paths, Spline Cleaner simplifies curve management and ensures your splines are clean, efficient, and ready for use in any 3D model.

Key Benefits of Spline Cleaner

1. Streamline Spline Management and Cleanup
   Spline Cleaner provides an advanced suite of tools to batch-process splines efficiently. Perfect for imported CAD and vector files, it helps eliminate overlapping, disorganized, or duplicated curves, automatically organizing them with smart filters like size, length, proximity, and layer. This tool is especially valuable when working with hundreds of shapes, saving hours of manual selection and cleanup.
2. Optimize and Automate Spline Edits
   With Spline Cleaner, you can select, attach, detach, or delete multiple splines quickly by applying filters to target curves based on specific attributes such as bounding box size, wire color, or vertex count. The plugin also enables precise vertex management, letting you weld, reduce, or normalize vertices effortlessly. This level of control is invaluable for creating smooth, clean splines, whether in architectural layouts, logo designs, or motion paths.
3. Comprehensive Spline Diagnostics and Monitoring
   The Splines Info Dialog offers real-time feedback on spline attributes like material counts, vertex numbers, and material IDs. The Diagnosis feature pinpoints potential issues like overlapping curves, empty shapes, or duplicate splines, ensuring your curves are optimized before extrusion. This interactive tool updates with every action, keeping your spline data organized and error-free as you work.
4. Prepare Splines for Accurate Extrusions and Modeling
   Spline Cleaner’s robust optimization tools ensure your spline curves are extrusion-ready. Features like Smart Normalize allow you to rebuild splines with even vertex distribution, while Reduce Vertices and Weld Vertices eliminate unnecessary points, creating smooth, clean curves that translate well into 3D geometry. These features ensure precision and efficiency, especially valuable in CAD-based or vector design imports.

Key Features and Tools in Spline Cleaner

• Smart Normalize: Rebuild your splines with evenly distributed vertices, ideal for creating consistent curves in architectural plans or logos.
• Filter by Open/Closed Condition: Easily sort and organize splines based on whether they’re open or closed.
• Support for Material IDs: Maintain material assignments across all operations, ensuring consistent appearances for complex models.
• Advanced Error Detection: Identify and fix overlapping or empty shapes with the Diagnosis tool, ensuring smooth extrusions.
• Automated Filters for Efficient Selection: Use nine distinct filters to select, attach, or delete shapes by criteria such as size, wire color, and layer.
• Vertex Management Tools: Weld, optimize, or reduce vertices for refined spline curves, minimizing geometry clutter and enhancing performance.
• Explode and Reverse Tools: Detach segments or reverse splines with options to preserve material IDs for better extrusion control.
• Viewport Data Exposure: See real-time spline data like vertex numbers and material IDs in the viewport, providing immediate feedback as you work.

Ideal for Designers, Architects, and 3D Artists Across Industries

Spline Cleaner is invaluable for both architectural visualization and graphic design, excelling in projects that rely on spline-based workflows. Its automated tools streamline time-consuming tasks, from preparing CAD layouts to organizing vector paths, allowing you to work more efficiently and deliver polished results. This plugin is indispensable for any professional working with 3ds Max who wants to elevate their workflow, reduce manual edits, and achieve high-quality, clean spline results ready for any 3D application.
