Load/import standalone STEP file (enclosure) in the PCB editor / 3D viewer to check fit?
Hi all, I’d like to check whether my PCB fits in an enclosure. I have a STEP file of the enclosure, and I want to see it together with my board in the 3D viewer. As far as I can tell, KiCad cannot import a standalone STEP file. The 3D viewer has no import option, and the PCB…

kisi – fast SI/PI checks for KiCad boards, right in your browser (feedback wanted)
Hi all, I’ve been building kisi , an open-source (GPL-3.0) signal/power-integrity checker for KiCad boards. It started as a pure visualisation project for a university PCB design course, but it has grown into something that might actually be useful to some of you. Drop a…

Zone in a zone
I’m designing a board for LoRa and have a question about the SMA-jack. Manufacturer recommendation is: Use a bottom ground plane (done) Use a full ground in the top side where the jack sits (done) Keep RF signal path to the jack short and straight (done) On the board I also have…

Multi Channel with Combined Bus Syntax
In a multi channel design I defined a bus for my analog signals inside the sub system: {V+[2:0] V-[2:0]} and connected it to a hierarchical port. I placed 5 of these sub system into the root schematic and connected the 1st subsystem to: {V+[2:0] V-[2:0]} the 2nd subsystem to:…

Via delay calculation inconsitency
Hello everyone, I’m trying out a new design using time-delay matching instead of length matching. However, I’ve noticed some strange behavior… If I place a track on the first layer and add vias to different layers, going from the bottom layer to higher layers (see picture), I…

How to add an exception rule for a single thermal pad or block zone from reaching it?
My 2-layer layout uses a solid bottom ground layer plus a ground zone on the top layer to fill all void areas between signal and power traces. By bad luck there is a single THT ground pad which can only be reached through a small bottleneck and the algorithm for thermal pads…

How to convert the only 2nd-level hierarchical schematics sheet into the new top-level sheet?
I am using KiCAD 10. For historic reasons my project evolved into a project which has a single top-level schematics with only a single hierarchical sheet on the 2nd level and a few more sheets below that. The structure looks like Sheet A | `-- Sheet B | +-- Sheet B.1 | +-- Sheet…

Symbol lib gone wild (having changes not made by myself)
Hello everyone I almost got a heart attack, the sudden a lot of my symbols of the company’s library got GIT red exclamation marked. But… I didn’t do anything. I first suspected AI having left its cage… but I don’t think so. I eventually noticed there is no “real” change, just…

There is a new kind of pad: “non-component”
Continuing the discussion from Post-V10 New Features and Development News : Post-V10 New Features and Development News There is a new kind of pad: “non-component”. These are pads that are designed to be used as footprint connections, but don’t represent connection point for…

Courtyard, what else?
Hello, I would like to add an exclusion zone to a footprint around the mounting screws, so that a component can be placed over that area without encroaching upon the screws. In the example shown in the image, I placed a courtyard over the head of the mounting screw; this results…

Never send KiCad project to the factory
Only Gerber, or better IPC-2581. Project file is not manufacturing data. Why almost nobody uses IPC-2581 yet? 10 posts - 8 participants Read full topic

KiCad EM Stackup Exporter (Open)
Hi people of KiCad, For the last 2 weeks or so, I was wrecking my mind on making a KiCad PCB to 3D model (Visual and Simulation) tool. The purpose was to provide myself a tool which can export EM ready board which has the true solid stackup of PCBs as close to the fabrication…

Round ends shape - import from EAGLE
I believe I posted on this here in a similar context. It was about PADs looking funny. When importing an EAGLE project (9.x Autocad - I abandoned EAGLE for reasons of the commercialisation having taken place on the product), mounting pads with an electrical function were looking…
