SelfCAD is Now Volume-Based: What You Need to Know

It can be difficult to design 3D models that are both clean and printable. Additional cleaning is usually necessary before printing or exporting complex structures due to overlapping faces, non-manifold geometry, or broken meshes.

In response to these frequent issues, SelfCAD has released one of its most significant modelling updates to date. A new Sweep Tool and enhanced versions of the Add Thickness and Bevel tools are included in the most recent update. A volume-based modelling methodology powers these updates, simplifying and improving the process of building robust, accurate models.

What's New in SelfCAD's Latest Modeling Update?

To make complicated modelling tasks easier, SelfCAD has added three new features to its modelling toolbox. These tools now employ a volume-based method to generate solid geometry while decreasing typical mesh mistakes, rather than depending solely on conventional surface operations.

As a result, you can put more effort into creating the models and less into correcting them.

Here is what's new:

• An all-new Sweep Tool
• A redesigned Add Thickness Tool
• Enhanced Bevel Tools with a new Solid Mode
• Taken as a whole, these enhancements streamline the process of making models that are both 3D-printable and ready for production.

You can now work faster and with clearer geometry from the start when designing mechanical parts, artistic models, architectural concepts, or items for 3D printing using these new tools.

Introducing the New Sweep Tool

New to this version is the Sweep Tool, one of its most notable features. By dragging a 2D profile along a chosen route, the Sweep Tool enables the creation of intricate 3D geometry. Pipes, rails, handles, wires, ornamental trimmings, frames, and countless other curved things are frequently fashioned using this method.

You just need to specify a profile and a path instead of painstakingly constructing these objects by hand. Automated geometry generation is a feature of SelfCAD. The modelling process becomes faster without sacrificing accuracy because of this.

Two Powerful Sweep Modes

Depending on the needs of your project, you can choose between two modes with the new Sweep Tool.

Exact Mode

Exact Mode is quite precise when it follows the chosen course.

When precision in dimensions is of the utmost importance, this mode is perfect. Exact Mode follows the path precisely, making it ideal for designs that require accurate dimensions and sharp edges.

You can trust the result when you use Exact Mode for projects that require accurate curves and controlled dimensions.

Solid Mode

Solid Mode constructs tidy, solid objects straight from the start, rather than geometry that might have non-manifold edges or overlapping faces.

This automatically smooths transitions around corners, removes overlapping faces and internal intersections, and creates clean, manifold geometry that is ready for further editing or 3D printing.

With this method, you won't have to deal with the usual mesh problems that crop up during sweep operations.

The end product is geometry that is less prone to errors and more suitable for 3D printing, editing, and exporting.

Why the New Sweep Tool Matters

The Sweep Tool dramatically expands what users can create inside SelfCAD.

It simplifies the design of objects that would otherwise require multiple modeling operations.

Some examples include:

• Pipes and tubing
• Electrical cables
• Handrails
• Furniture frames
• Automotive components
• Decorative moldings
• Structural supports
• Jewelry designs
• Mechanical channels

Instead of combining numerous shapes manually, users can generate these models in just a few steps.

This not only saves time but also produces cleaner geometry.

Improved Add Thickness Tool

When getting models ready for manufacturing or 3D printing, adding wall thickness is a must. Transforming thin surfaces into solid shells is a common prerequisite for successful printing of such materials.

Using its new volume-based modelling engine, SelfCAD has revamped its Add Thickness Tool from the ground up.

Even when dealing with extremely detailed or complex models, the upgraded tool reliably produces cleaner shells.

The new process makes solid walls with uniform thickness all around the model, rather than erratic results or troublesome geometry. Print failures or geometrical problems are much less likely to occur as a result of this.

Better Performance on Complex Models

You have the new Solid Mode, which rebuilds the object as a single continuous solid using volume-based modelling, and Offset Mode, which swiftly offsets the model's surfaces and is great for simple designs. In contrast to conventional shelling techniques, which can lead to invalid meshes, overlapping faces, or self-intersections when dealing with complex geometry, Solid Mode seamlessly integrates intersecting regions into a manifold model that is both watertight and has smooth transitions. 

As a result, it's ideal for use with organic models, scanned items, medical models, artistic ideas, and complex meshes that require additional editing or 3D printing. Designers can confidently produce stronger, cleaner, and more printable models using Solid Mode, which takes slightly longer to process but greatly decreases mesh mistakes and eliminates much of the manual cleanup required after adding thickness. 

Enhanced Bevel Tools

The Bevel Tool, a widely used component of SelfCAD's modelling suite, has also received an improvement.

Beveling is a tool that designers can use to reinforce printed components, make chamfers, enhance the look of their products, and soften sharp edges.

In addition to the long-standing Offset Mode, the most recent upgrade brings a whole new Solid Mode. Depending on the geometry type, this provides users with more flexibility.

Offset Mode

The classic bevel workflow that Offset Mode is known for is still available to current customers.

For many common modelling jobs, where the use of traditional edge offsets is adequate, it performs admirably.

Those who like the old-fashioned method won't have to make any changes to their workflow to keep using it.

New Solid Mode

Among the many enhancements to the Bevel Tool, the new Solid Mode stands out. To create crisp chamfers and fillets, Solid Mode employs volume-based operations rather than depending solely on offset calculations.

This drastically lessens problems like non-manifold geometry, self-intersections, and overlapping faces. Successful beveling of even challenging models with sophisticated edge networks becomes considerably easier.

This offers a considerable boost in dependability for designers making models suited for production.

The Benefits of Volume-Based Modeling

The shift toward volume-based modelling in SelfCAD is the basis of this version. It is not uncommon for conventional mesh editing to introduce undetectable geometry issues that might not be apparent until much later in the design phase or even during the 3D printing process.

By representing objects as solid volumes rather than collections of surfaces, volume-based modelling solves a lot of these problems. There are many significant benefits to this. 

Cleaner Geometry

Solid operations naturally reduce overlapping faces and internal mesh problems. Models remain easier to edit throughout the design process.

Watertight Meshes

Watertight geometry is essential for successful 3D printing. The new tools generate cleaner solids that require less repair before exporting.

Greater Reliability

Complex operations such as sweeping, thickening, and beveling become much more stable, even on advanced models.

Faster Workflow

Users spend less time repairing geometry and more time focusing on creative design.

Who Will Benefit from These New Tools?

Almost every kind of SelfCAD user will appreciate these enhancements. With fewer geometry errors, product designers can produce prototypes that are cleaner. Mechanical engineers are better able to produce precise technical parts.

More accurate modelling of complex structures is now within the reach of architects. Designers of jewellery are able to construct complex shapes while preserving the integrity of solid geometry.

By reducing repair work before slicing, makers and amateurs may prepare models for 3D printing. Tools that simplify complex modelling ideas while delivering results that are comparable to those of professionals are equally useful for educators and students.

Experience the Next Generation of Modeling in SelfCAD

SelfCAD keeps bringing new features that boost model quality and speed while also making professional 3D modelling more accessible.

Improved Bevel Tools, a revamped Add Thickness Tool, and the new Sweep Tool all contribute to models that are easier to clean, more trustworthy, and ready for 3D printing. Designers may spend less time fixing geometry and more time making their ideas a reality using SelfCAD's volume-based modelling.

With these new tools, you can model anything with more control, more precision, and a smoother experience overall, whether it's a mechanical component, an artistic design, an architectural concept, or a model for additive manufacturing.
