New Geometric Modeling Capabilities: From Constraint Status Checks to Better Dragging in C3D Solver
Ksenia Nosulko, senior math software engineer, C3D Labs, tells about new 3D modeling features in C3D Solver. C3D Solver manages relationships between geometric objects. It consists of a 2D and 3D solver. They auto-update the geometry as it is edited while maintaining the existing constraints. These...

From Segment to Point and Back. Geometry Evolution in C3D Solver
A line segment is a basic geometric object most widely used in drawings or sketches. Can you guess, how many math representations a segment has? While you’re counting, let me tell you how C3D Solver handles segments, and about the new option: degenerate segments. Please note that the term “degenerate”...

C3D Solver: Parametric Drafting of 2D Patterns and 3D Assembly Modeling Improvements
Alexander Alakhverdyants introduces innovations in the 2D and 3D solvers developed by the C3D Solver team. What are the solvers? Solvers are software libraries that apply relationships to geometric objects. We call these relationships “constraints”. There are two types of constraints: logical (tangent,...

Nanosoft Uses the Geometric Kernel From C3D Labs for Its Import Substitution Project
The nanoCAD platform, which can model even the most complicated products, now uses the C3D Labs geometric kernel. Nanosoft has switched to the C3D Labs geometry kernel from a component from an international vendor. The kernel is an integral part of the CAD platform. It does the math for 3D object...

C3D Solver’s New Interval Dimension Functions
Recently, we introduced distance interval dimensions in our article on new tools in C3D Solver 2023’s parameterization module. This is a subtype of driving dimensions, but with several differences. So, in this post we describe the differences between interval and driving dimensions. As a bonus, we are...

C3D Solver Developments: Offset Curves and Interval Constraints
In this note, we are focusing on two new features in our C3D Solver 2022 constraints module, and demonstrate how to use them with code fragments. The constraint manager includes two- and three-dimensional solvers that allow you to impose a variety of constraints on bodies in both 2D and 3D space....
