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 * Added a rebuilt sketch system with spline editing, mirroring, constraint handling, and selection from the feature tree * Added model parameters with unit-aware inputs and sliders for driving dimensions interactively * Added Material objects with a dedicated materials editor, PBR properties, and nested material libraries * Added SVG import for sketch profiles, including self-intersection resolution and fill contour classification * Added STEP export with proper unit conversion, plus GIF and WebM export for turntables and motion * Added drawing options with dimension mode support * Added section views, face and edge selection improvements, soft shadows, and transparent material rendering * Added multiple viewport navigation schemes — Davinci Native (default), Onshape, SolidWorks, and Inventor — with right-click access to viewport settings * Improved [Onshape](/pages/integrations/onshape)-linked geometry handling to preserve source geometry and mass properties * Improved compile performance with speculative compilation, background compilation, caching, and parallel child loading ### Assemblies & Motion * Added assembly modeling with mates, including mate flipping, visibility toggles, and highlighted mate references * Added a place command for freely posing components within an assembly * Added the ability to import other model objects into assemblies, including circuits and mixed assemblies * Added joint dragging with enforced joint limits and smooth slider control * Added motion studies with capture, playback, and export to GIF and WebM * Added exploded views with adjustable offsets, idle spin, and rotation during explode * Added assembly instructions generated from the fully solved assembly * Added collision and interference detection with verification checks for clearance, distance, bounding box size, and component count * Added toggleable reference visibility with bulk controls ### 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](/pages/editor/widgets/agent-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](/pages/modeling/objects/figure) * Added swimlane support with lane dragging and chaining via any relationship * Added an equation mode for figures * Added a linkage mode for rendering cabling * Added customization options for interface mode figures * Added more toggles for Gantt figures and fixed rendering errors * Improved activity mode rendering with manually positioned edge points * Improved consistency of generated figure scopes and interconnect linkages ### Wiring & Harness Design * Added a new wiring view for designing cable harnesses * Added multi-cable splitting with build instructions for harness assembly * Improved wire routing, overlap handling, and edge processing * Added compact, multi-column layouts for large harnesses ### Workspace & Navigation * Added a workspace bottom bar with source control status, stale value indicators, and quick widgets * Added unified breadcrumbs with drag-and-drop support * The sidebar is now always visible, with menu actions consolidated into the user menu * Added workspace pinning and a full-width workspace switcher * Workspace sheets are now retained and lazy-loaded for faster tab switching * Replaced browser-native dropdowns with consistent custom menus throughout the application * Added inline renaming when creating objects from the index, plus improved index scrolling and multi-select * Added folders for organizing projects, and Enter now opens the selected project * Refreshed the application color system * Added [project settings](/pages/editor/project-settings/project) 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 * Pasted text now strips external styling for cleaner documents * Improved matrix cell rendering and fixed row description wrapping ### Version Control * [Source control](/pages/editor/widgets/source-control) now stores merge history and renders a proper commit graph * Rollbacks now record authorship and compute faster with client-side processing * Stale untracked generated files are cleaned up on branch change * Fixed git stability during storage transitions ### Export & Interoperability * Improved SysML v2 export with proper unit handling, resolved references in action conditionals, and corrected test case exports * Model object exports now bundle referenced assets so imports restore references correctly * Improved DOCX, image, and figure export fidelity ### [Public API](/pages/api/introduction) & SDKs * API sessions are now confined to their own conversation, with agent events relayed to the caller's live clients * Added validation for objects written through the public API * Added canonical error responses and robust handling of compound project IDs * Programmatic callers can now name the persona and see delivery failures explicitly * MCP servers are now told which conversation is calling them * Added configurable agent models through the public API * Added a usage ledger and support for Code objects acting as SDK clients * Improved Python and TypeScript SDK reliability ### Administration & Deployment * Added support for custom SSL certificates * Added draft saving for LDAP configurations * Added a v2 health check endpoint and a liveness probe behind the browser's connection indicator * Added metering attribution to LLM usage reporting and Amazon Titan embedding support on Bedrock * Improved the platform logging pipeline ### Reliability & Performance * Bulk model verification now runs in parallel * Every collaborator now gets a distinct color in the authorship wheel * Fixed race conditions in storage switching and kept session clones in sync across clients * Fixed organization page errors, sidebar closing issues, overlapping windows, and various rendering glitches * Added general stability, interaction, and display improvements throughout the editor
