Fillets, Nothing More Than More Fillets
by Sergey Biryukov, mathematician and programmer at C3D Labs Creating 3D fillets is one of the most complex tasks undertaken by a geometric kernel. Before creating the fillets, the application must know the arrangement of the 3D faces involved and, at the same time, be aware of adjacent faces that...

How 3D Models are Stored in DWGPart 3: Modifying 3D Models with the Help of Teigha
In the previous article, I explained that describing 3D bodies using Constructive Solid Geometry (CSG) involves significant difficulty in modifying the shape of the bodies. Yet the need for modifications arises as design is an iterative process. The reasons for model revision are extensive: new calculations,...

How 3D Models are Stored in DWG. Part 2: Using Boolean Operations to Create 3D Models with Teigha
In the previous article, I talked about the differences by which 3D models are stored in CAD files, as compared to how they are constructed by designers. Designers do not need to describe the shapes of the models they’re designing with mathematical formulae. Instead, the application's user interface...

How 3D Models are Stored in DWG. Part 1: The Terminology of B-reps
When we speak of 3D models in the mathematical sense, we usual refer to the “boundary representation” of solid bodies — their skin, as it were. Solids are so-called because their shape tends to be constant (cannot be easily modified), and their material is considered to be homogeneous throughout....

C3D Modeler for Teigha Updated for 2018
C3D Labs announced it has updated the C3D Modeler for Teigha. This is a lightweight version of the C3D Modeler geometric kernel designed to develop 3D applications on the Open Design Alliance’s Teigha platform. Developers who use Teigha’s API gain access to 3D solid modeling functions through this...

The Fall and Recovery of a Mold
Software component developers tend to be far removed from the end users of the products in which their components are employed. Recently, however, we connected directly with a KOMPAS-3D MCAD user to solve an issue involving mold design. It seems that 3D models were being exported incorrectly to data...
