Engineering insights, technical deep-dives, and industry perspectives from the NeuroCAD team.
200-Part Assemblies Grind in SolidWorks. NeuroCAD Treats Update Latency as a Contract.
Onshape made assembly-rebuild latency observable. The next step is making it contractual: a published SLA for incremental update with a CI regression alarm. Here is what that looks like.
Audit Every Ply. AS9102 Says You Have To. CAD Says Good Luck.
AS9102 demands per-ply traceability for aerospace composites. Today that lives in spreadsheets next to the CAD file. NeuroCAD makes it a graph edge — one per ply, machine-checkable end to end.
Reproducible Builds Solved 'Works on My Machine'. CAD Never Got the Memo. Until Now.
Software learned to build byte-identical binaries across machines and years. CAD still treats 'the file opens and looks right' as good enough. NeuroCAD ships a 12-point Replay Acceptance Contract.
Toolpath Gouges: Every CAM Vendor Claims to Detect Them. FreeCAD's Bug Tracker Says Otherwise.
FreeCAD #22178 is the public evidence that open-source CAM gouge detection misses things. Here is how SDF makes the algorithm short, exact, and testable — with the test PR #25753 lacked.
Why Aerospace Tech Pubs Still Place Callouts by Hand — and What an Algorithmic Contract Looks Like
S1000D tells you what a callout is. ATA iSpec 2200 tells you what code it carries. Neither tells you where on the page it should sit. Here is what a placement contract looks like.
When You Change One Parameter, Why Does CAD Recompute Everything?
Feature-tree rebuild lag is a solvable problem. Incremental computation has had the answer for decades. Here is how NeuroCAD's Distributed Constraint Graph touches only what changed — and how we plan to benchmark it.
Filling the N-Sided Hole: Why Two Kernels Disagree, and How We Make Them Shake Hands
Closing a 5-sided patch is a 30-year B-rep research problem. SDF smooth-blend solves it in one operator. But how do you know the two answers agree? Here is the contract.
What Happens When You Change a Parameter in CAD? Four Graphs, One Atomic Commit
When a parameter changes, geometry, identity, and evidence all shift at once. Most CAD only tracks one. NeuroCAD tracks four, atomically — like Git, but for engineering truth.
An Open Conformance Suite for Pipe, Cable, and HVAC Routing
ISO 15649, AS50881, ASHRAE — every routing standard is cited by every vendor and tested by no one in public. NeuroCAD proposes a 10-test open conformance suite to close the gap.
Cam-Follower Contact in SolidWorks Is a Tessellated Approximation. NeuroCAD Computes It in Closed Form.
If your camshaft simulation reports follower acceleration with a phantom 12 g spike at the rise-dwell transition, the spike is almost certainly not in your motion law. It is in the mesh.
Sheet-Metal Unfolding from Signed Distance Fields
Every commercial sheet-metal unfold algorithm walks a B-rep face graph. SDF kernels have no graph to walk. Here is how NeuroCAD plans to unfold anyway — using geodesics on the zero-isosurface.
Should-Cost Software Needs Feature Recognition. Every Published Algorithm Assumes B-Rep. SDF Needs a Different Approach.
Procurement engineers quote parts by walking a B-rep face graph. NeuroCAD has no face graph. Here is how to recognise machining features directly from a signed distance field.
Why Two CAD Kernels Should Agree on the Same Sketch — and How NeuroCAD Verifies It
Closed 2D profiles look trivial, but the gap between NURBS and SDF representations is where modern CAD silently diverges. Here is how NeuroCAD pins the agreement as a measurable contract.
Sculpting and CAD Surfacing Were Never Supposed to Talk. NeuroCAD Measures Cashman's 2009 Bridge.
Cashman wrote the bridge between subdivision surfaces and NURBS in 2009. Sixteen years later, NeuroCAD is the first CAD platform to wire it as a release-gating regression test.
Mold Design Has 30 Years of Literature, Zero Open-Source Unit Tests. NeuroCAD Changes That.
Undercut detection, parting-line generation, draft analysis: textbook material in any tooling shop, missing from every open-source CAD as a tested toolchain. Here is the gap and the plan.
Suppress a Part in Your Assembly. Watch Your 4-Bar Linkage Break. SDF Lets You Suppress Safely.
The mechanism designer's variant of CAD's oldest scar: hide a connecting rod, the joint reference dies, the kinematic loop falls apart. NeuroCAD binds joints to feature-graph IDs, not topology.
The Topological Naming Problem Is a 30-Year Scar on CAD. SDF Cuts It Out by Construction.
Every CAD user has hit it: hide a feature, the model breaks. We show why this happens, why it cannot be fully fixed inside a B-rep kernel, and why NeuroCAD's SDF makes the failure unrepresentable.
