Version 5.0.0 - CAD, Circuits & Simulation

Version 5.0 brings mechanical CAD, electronics design, and physics simulation into Davinci as first-class engineering workflows. Alongside them, this release delivers a rebuilt agent chat experience, a redesigned include system for sharing packages across projects, a new wiring view, refreshed workspace navigation, and a broad set of platform improvements.

​
CAD Modeling

Davinci now includes a full parametric CAD environment for authoring real geometry directly inside your model.
  • Added an object-oriented CAD language with sketches, extrudes, revolves, holes, fillets, and chamfers

  • Improved compile performance with speculative compilation, background compilation, caching, and parallel child loading

​
Assemblies & Motion

​
Circuits & PCB Design

Version 5.0 introduces electronics design, taking Circuit objects from schematic capture through board layout and out to 3D.
  • Added schematic authoring in a three-pane view with code editor, schematic canvas, and output terminal
  • Added component libraries loaded directly from KiCAD symbols and footprints, with clear feedback on missing symbols
  • Added automatic schematic layout with improved line segments and multi-sheet handling
  • Added PCB board layout with component placement, automatic routing, and fully custom manual routing
  • Added multi-layer board support, BGA handling, via placement rules, and silkscreen reference editing
  • Added support for complex board outline shapes
  • Added design rule checks, including clearance verification
  • Added SPICE simulation support for circuits
  • Added board-to-3D conversion so circuits can be rendered as 3D geometry and placed in assemblies
  • Added agent workflows for circuit generation, layout, and routing

​
Simulation, Compiled

Version 5.0 rebuilds simulation around a fundamentally new paradigm: a simulation is no longer a single solve. Set up a study once — mesh plus parametric boundary conditions — compile it in minutes, and the entire solution space becomes a live result that answers in about a tenth of a millisecond per solve. Every answer is a true physics solution carrying a provable accuracy guarantee, turning what used to be an overnight batch process into an interactive design instrument.
  • Added compiled solution spaces: declare parameters across loads, materials, and boundary conditions, compile once, then explore every combination of values instantly
  • Added live 3D field exploration with a slider on every declared parameter — displacement, stress, and temperature fields update in real time, sweeping thousands of design points per second
  • Added certified results: every solve carries a rigorous mathematical error bound, not a statistical confidence score or an AI approximation
  • Added full-order verification solves that can be run at any point in the solution space to confirm the certified answer
  • Added eight analysis types: static structural, steady thermal, coupled thermo-elastic, modal, harmonic, random vibration, shock response, and transient
  • Added certified geometry families so dimensional CAD variations can be explored with the same instant response
  • Solution spaces run identically in the browser and on the server, so exploration is immediate with no round trips to a solver
  • Added quantities of interest for tracking derived engineering values live across the space
  • Added a rebuilt simulation setup view integrated with the CAD environment, with parametric boundary condition authoring including a new bearing type
  • Added agent support for setting up, compiling, querying, and verifying simulations
  • Added clearer progress reporting and administrator controls for enabling simulation authoring

​
Agent & Chat

  • Rebuilt the chat experience so switching between conversation tabs is instant
  • Added conversation renaming, with new conversations named from the request that opened them
  • Added a context window panel for inspecting exactly what the agent currently sees
  • Added automatic context management for long conversations that trims older content while preserving recent turns
  • Added dynamic model configuration options for conversations
  • Improved plan rendering with collapsed plan updates and better feedback when a plan change fails
  • Improved image handling, including sending images at proper fidelity and clamping oversized captures
  • Cancelled queued messages are now restored to the composer instead of being lost
  • Added progress reporting when importing legacy chat history

​
Includes & Linked Projects

  • Rebuilt the include system with fully resolved pointers and automatic migration of legacy projects
  • Added linked projects with chained includes so shared packages resolve across a chain of projects
  • All base packages are now treated as public for inclusion
  • Added dynamic includes for public objects outside the source package
  • Include updates and removals now apply together as a single synchronized action
  • Improved the include package explorer popup, including waiting on in-flight operations
  • Prevented merge conflicts and accidental parenting of new objects into included content

​
Figures

  • Added project settings import and export, including importing settings from an existing project at creation
  • Added one-time file share links

​
Documents & Editing

  • Improved text highlighting quality and highlight colors in documents
  • Improved caret placement, blank-line selection feedback, and typing responsiveness
