12.02.2020 Multi-thread Support Arrives in C3D Toolkit

There is a saying among programmers that reminds us of the importance of multi threading in applications, “Parallel computing is our future. And that's forever!”...

24.12.2019 Calculating Distances between Bodies with C3D Modeler

Today we want to focus on one of C3D Modeler’s geometric calculation functions. Along with its ability to build and edit three-dimensional models, C3D Modeler supports...

29.11.2019 New in C3D Modeler: Stamping with a solid tool

The functionality of the C3D Toolkit is regularly upd ated not only with new methods of building bodies, but also with improvements to previous algorithms, expanding...

20.11.2019 New in C3D Modeler: Curvature Graphs and Curve Analyses

New functions added to the C3D Toolkit are often the result of requests by our customers, as well as improvements we make to the existing algorithms. The functions...

15.10.2019 New in C3D Modeler: Offsetting Curves and Surfaces with Variable Displacements

September’s new revision of the C3D Toolkit includes new ways to construct offset curves in two- and three-dimensional space, as well as to offset surfaces. ...

18.09.2019 Configuring interaction between 2D and 3D solvers within the C3D Solver parametric kernel

Introduction This article is an answer to the question raised by one of our customers during the C3Days conference on how to jointly use 2D and 3D solvers in...

19.12.2018 New Tools and Code Samples for Visualize 3D Modeling in C3D Vision 2019

Recently, we released a new version of C3D Vision, the 3D engine part of our C3D Toolkit. It operates with polygonal models and is responsible for drawing visual...

03.09.2018 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...

27.08.2018 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...

21.08.2018 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...
