KiCad 10 Features: What These Updates Change in PCB Design

What This Video Covers

This video reviews two open-source releases that change how many engineers capture schematics, reuse layouts, and fit boards into printed enclosures: KiCad 10 (released 20 March 2026) and FreeCAD 1.1. On the KiCad side, the walkthrough covers STEP-only official 3D models, directory-style symbol libraries, Windows dark mode, schematic variants for alternate BOMs and DNP parts, hop-over wire display, schematic groups, and PCB design blocks. Practical examples include a reusable voltage-regulator block and a USB-C connector whose reversible routing and tight clearances are costly to redraw on every new PCB prototype.

The second half shows FreeCAD 1.1 usability work that matters after the board outline is frozen: clearer selection, a transform tool with a custom origin, quick measure, projected external geometry, and generate-internal-faces for enclosure walls and PCB pockets. Together the updates support a cleaner path from schematic to PCB assembly and a first online PCB quote without rebuilding connector fanouts or enclosure pockets from scratch.

Key Highlights

• KiCad 10 ships official 3D models as STEP only and adds schematic variants so one schematic can drive multiple BOMs, DNP states, and replacement parts without forking the project.
• PCB design blocks now store physical layout as well as schematic circuitry, so high-risk connectors such as USB-C can be routed once to fab rules and reused.
• FreeCAD 1.1 reduces enclosure rebuild work by projecting real geometry into sketches and generating multiple internal faces from one sketch—useful when a pocket must match a finished board outline.

KiCad 10 Library and Schematic Changes That Affect Production Files

KiCad 10 is not a cosmetic point release. The official project announced Version 10.0.0 on 20 March 2026 after 7,609 unique commits in the development cycle, plus 952 new symbols, 1,216 new footprints, and 386 new 3D models. More than 78% of official footprints are now generated from data rather than drawn by hand, which reduces the silent mismatches between a library footprint, its 3D body, and the courtyard a pick-and-place program will use.

Two library changes shown in the video have direct manufacturing consequences. First, official 3D models are STEP only. Dropping the older mixed formats shrinks the install set and, more importantly, makes the 3D viewer and the STEP export that mechanical teams consume the same geometry. That matters when an enclosure pocket, a standoff pattern, or a connector keep-out is derived from the board model rather than from a hand-measured outline. Second, symbol libraries can now live as a directory of individual symbol files (_simdir) instead of a single packed library file. Adding a new vendor part becomes a file drop rather than a library-edit session. The video notes a practical upgrade pitfall: a Windows update to version 10 can break existing library paths until they are pointed at the new directory layout. Treat library paths as a project-onboarding checklist item, not an afterthought.

Schematic variants are not a version-control system. They are a single schematic with alternate properties: different fitted values, omitted parts (do-not-place), or substitute footprints when a line is short. That is the pattern OEM teams already use for regional SKUs, cost-down builds, and second-source passives. The risk is process, not software. Each variant still needs its own BOM, centroid file, and assembly drawing. A DNP capacitor that remains in copper but is missing from the stencil and pick-and-place file is a valid variant; a DNP that is also removed from copper without a matching Gerber set is a different board. Lock variant names to the same identifiers used in the assembly quote so procurement and the SMT line are looking at one configuration.

Hop-over display is a documentation feature, not a netlist feature. Unconnected crossings render as arcs so a reviewer does not assume a junction. Enable it per schematic under File → Schematic Setup → General → Formatting → Connections. Some teams will leave it off on dense sheets; turn it on for review packages and customer PDFs. Schematic groups, now available on the schematic side as they already were on the board, make design blocks easier to move—but the video flags a real editing quirk: objects added after the block is placed do not automatically join the group. Dragging the group then leaves the extra capacitor or diode behind, and copy/paste can keep the new object tied to the group unexpectedly. Before you freeze a reusable block, enter the group, confirm membership, and save the block again.
