If you’re looking to try a new, open source 3D modeling CAD suite, especially one with automation-friendly interfaces, take a look at SolidCraft. It’s under development but there’s support for all the usual features like sketches, solid modeling, and constraints as well as a full parametric feature timeline.

A parametric timeline essentially means the model exists not as a single discrete object, but as the sum of a sequence of operations. One advantage of this is being able to set things up so that if one changes a value (like wall thickness), all the features that depend on that change automatically get rebuilt as a result. But there’s more!

Written entirely in Rust, SolidCraft can run as a desktop app or as a web app in a browser. Everything the user can do in SolidCraft is a command with JSON parameters, and it offers a built-in headless command line interface and even an MCP (Model Context Protocol) server built specifically to give AI agents a way to use the program, should one be interested in experimenting with that sort of thing.

SolidCraft is still in early development, but so far quite a few features seem to work as they should. Check out the development roadmap for details, and there’s a live online demo if you’re in the mood to click around and get a feel for things.

We have seen quite a few open-source, browser-based CAD efforts over the years and it’s encouraging to see developers continuing to explore fresh ideas and features in the CAD landscape.

Recently [John Spicer] of the EDG C++ compiler front-end project announced that the project will be made open source, from now on managed by the non-profit C++ Alliance. Related source code can be found on the GitHub account.

The Edison Design Group (EDG) is a US company which has made compiler front-ends since 1988, previously also for Java and Fortran. They are used in the Intel C++ compiler, Microsoft’s VC++, NVIDIA’s CUDA compiler, as well as many other commercial products. Last year the decision was made to shutdown the company in 2026 and transition to an open source model, with the details outlined on the EDGCPP site.

Although far from the only C++ front-end, EDGCPP will be very interesting still for supporting bleeding-edge features and having been used in such wide-ranging, demanding applications by a host of commercial customers. For most of us C++ developers our contact with it will have been via the MSVC and Intel Compiler Collection tooling, but of course it’s just one part of the entire toolset.

We’re looking forward to seeing what this means for the wider open source C++ ecosystem, especially as it pertains to GCC and LLVM’s Clang.
