C3D Labs produces kernel software, and so can be considered a competitor of Parasolid/D-Cubed (from Siemens) and Spatial from Dassault Systemes.
The C3D kernel was originally developed 25 years ago by ASCON Group for their KOMPAS-3D solid modeler, but then a decade ago spun off the kernel group as an independent company, C3D Labs. The company has been very aggressive at building out functions, such as its new programmable F-curves.
The company has held an annual conference for a while now, but in Russian. Given the modern switch to Zooming conferences, this year it was held in English. (See figure below.)
Oleg Zykov, ceo of C3D Labs, reported during his keynote address that the company is doing well, having hired nine more employees and released updates to C3D Toolkit in 2020 and 2021 on time.
The company offers its programming toolkit with five modules for developing software in the areas of MCAD, BIM, CAM, and so on. Each can be used on its own, or together with the others:
-
C3D Modeler — geometric kernel
-
C3D Solver — parametric solver
-
C3D Vision — visualization engine
-
C3D Converter — data exchange
-
C3D B-Shaper — polygon mesh to b-rep converter
There are two more modules that C3D is releasing, C3D FairCurve Modeler and C3D Web Vision.
During the conference, customers described how they deployed C3D’s modules, including professor Rushan Ziatdinov of industrial engineering in South Korea (see figure below).
The C3D kernel has displaced other kernels in nanoCAD, Altium, VR Concept, and so on. It is used by developers at LEDAS Group and is available to members of the Open Design Alliance. c3dlabs.com/en

Update on the Flood
Thank you to friends and readers checking in to see how we are doing during what is now called “Canada’s worst natural disaster” with thousands displaced by flooding, all Canadian roads out of here cut, and Canada's largest port in Vancouver isolated. The flooding was the result of a tremendous rainstorm last Sunday and Monday, along with warmer temperatures melting snow.
Here is a picture I took last Monday morning of a pedestrian bridge in our local park in which we go for walks. Normally, the water goes under the bridge.
It’s weird: Thousands are stranded by mudslides and wrecked bridges or forced out of homes by flooding. For the other couple of million living in this region, life is normal, other than grocery stores running low on some food staples, gasoline being rationed, and we having to take detours around closed roads.
Restrictions on some grocery items and maximum fills of 30 litres of gasolineThe reason for life being mostly normal is due to our region’s agricultural farmland retention policy: most homes in our region are built on non-agricultural land, which means higher up, and so farms primarily inhabit the flood-prone flat lands, as this aerial photo of flooding at the Watcom interchange of the Trans Canada Highway amply illustrates.
The unknown is the longer-term impact. While mudslides are being cleared (one highway is already reopened to one-way traffic), the broken bridges on the critical Coquihalla and Trans-Canada freeways will take weeks to get replaced by temporary bridges and then years to fully replace.
The immediate solution is to work on bringing in goods (food and fuel) through the USA, with which our region has four border crossings and two rail crossings. We are, however, not the EU, so things don’t pass effortlessly between the two countries.

Contact Software launches a new version of its low-code Elements platform for handling digital business processes end-to-end.
Here is one example of its use: If your firm know that parts will have to be replaced at some point in the future due to new DIN standards, then you can define until-when or from-when parts are valid. The new validity takes effect automatically on the specified date, and also updates the parts list. contact-software.com/en/products/integration-platform

Letters to the Editor
It is striking how both Hexagon and Bricsys seem to completely stonewall any mention, or awareness of, photogrammetric reality capture as an essential complement to acquisition by point cloud.
Other firms in the reality capture/digital twins arena, such as Bentley Systems and Autodesk, have a foot firmly in both camps. Point cloud seems to have reached maturity as an expensive technology, while photogrammetry continues to evolve (and democratize) by leaps and bounds. How long can Bricsys ignore photogrammetry?

The editor replies: I don’t know that they are ignoring it. BricsCAD has the ability to place images and maps from a variety of sources.
Mr Foster responds: That’s not photogrammetry. Photogrammetry is taking hundreds or thousands of photos of the subject, such as with programs like capturingreality.com.
They identify same object in several images, thus triangulate the object’s 3D position, hence create a 3D model of the subject as a surface mesh (not points), which can optionally be wallpapered with fragments of the JPGs for a solid-looking, photorealistic model, which can be rotated and viewed from any angle.
Photogrammetric models are an alternative to point cloud models. Each is best for different purposes or different kinds of subject. Hybrids using both techniques are possible.
Photogrammetry is widely used in the construction industry. Bentley, for example came to photogrammetry first, then added point clouds later. Bricsys under the influence of Leica has so far done it the other way round. As with point clouds, Bricsys needn’t do the processing in-house (which Bentley does), but can reprocess/display/integrate various proprietary formats of external programs.
