Geometric Constraint Solving on Imported Data

Geometric Constraint Solving on Imported Data

One of the strengths of the D-Cubed 2D DCM and 3D DCM geometric constraint solvers is their ability to work with models imported from other systems. Of course, before the data gets to the solver it h…

Paul Sicking introduces the Central Technology Office

Paul Sicking introduces the Central Technology Office

In September last year Chuck Grindstaff announced a reorganisation of Siemens PLM Software. As part of this, my D-Cubed group, together with the other PLM Components groups, became part of a new unit…

Geometric Constraint Solving and Spin Surfaces

Geometric Constraint Solving and Spin Surfaces

In amongst all of the publicity around PLM Connection Europe it would have been easy to miss the announcement of the latest release of the D-Cubed 3D products . As it happens, the timing was a coi…

Major Milestones for the D-Cubed Components

Major Milestones for the D-Cubed Components

It’s human nature to assign a greater significance to some numbers. A 50 th birthday or anniversary is seen as much more notable than a 49 th or 51 st , although no sudden changes happen then. Howe…

Conics in Geometric Constraint Solving

Conics in Geometric Constraint Solving

As their name implies, conic sections (or just “conics”) are curves that are created by intersecting a conical surface with a plane. They are usually divided into three types:   &…

Geometric constraint solving – it’s all about special cases

Geometric constraint solving – it’s all about special cases

As I am writing this, we are part way through the process of making new releases of the D-Cubed Components. The 2D products (2D DCM, PGM) have just been shipped and the 3D products (3D DCM,…

Geometric Constraint Solving and Japanese Sangaku

Geometric Constraint Solving and Japanese Sangaku

Sangaku are wooden tablets which were inscribed with Euclidian geometry puzzles and displayed near temples or shrines. Here’s an example of one from over 200 years ago: A statement …

D-Cubed, Software and Saxophones – Q and A with Ian Morrison

D-Cubed, Software and Saxophones – Q and A with Ian Morrison

Behind the D-Cubed products there is an experienced and talented team of software engineers. In this post, I’ve dragged Ian Morrison away from the source code for a few minutes to answer some questio…

Technical Focus on Linear Pattern Constraints

Technical Focus on Linear Pattern Constraints

This is the first in a sequence of posts that will dip into particular aspects of D-Cubed components. As you might expect from products that are quite mathematical, some of the concepts can be rather…
