Hello,
I'm new to KiCAD, and after starting a project I've noticed, that:
Hi Rafal, welcome!
1. once I do create a PCB from new schematic, the parts are lumped
together pretty randomly. I tried to figure out where in the sources,
that happens, but wasn't able to locate relevant module ... this is
why I'm writing here. I'd like to modify the "initial creation" of PCB
so, that footprints are lied down "just like they are on schematic
diagram". Meaning, X-Y position of a part reflects its X-Y symbol
position. This is because 90% of the time, that would be my desired
component layout.
A dramatically better implementation (thanks dsa-t!) of this was merged
recently and will be in the next major release (v7). See
https://forum.kicad.info/t/post-v6-new-features-and-development-news/32633/76 for details. You can look at the underlying merge request to see where and how it's implemented. The merge request is at https://gitlab.com/kicad/code/kicad/-/merge_requests/1325
Hmm.. This will be useful during project modifications (which may be
more useful, since one spends more time fixing the project, then for
initial design), but I'm looking for initial layout. Small project with
small number of components will hugely benefit from "more or less"
correct initial component positioning.
Anyway, I'll look up the pull request, where I may get hints in the PCG
initialization code.
2. I've worked with hierachy sheets, and in particular, I've
replicated one sub-sheet to have an array of functionality (like
memory array). Since I'm doing most of the trace layout by hand
(autorouter still doesn't work for me) I have to repeat the routing
task for every subsheet with that same sub-functionality. A feature
that brings layout and routing of one sheet to components of its' copy
would be great.
Check out the "replicate layout" plugin in the plugin and content
manager. It does exactly this. There are plans to implement this in the
main application for a later version, but for now the plugin should get
you most of the way there.
OK thenx,
(BTW: as I said, I'm not using autoruoter ... because its' a plugin and
it fails with my <debian-11> version of java runtime 🙁, I hope it will
not be the same case with replication layout plugin )
3. then again, some of my projects are multi-pcb. It would help
greatly, if one could mark certain diagram-sheets (in the hierarchy),
that this particular level will be on separate PCB.... so that pcb
editor don't clutter the view with components, that are not destined
for that particular pcb (sub pcb).
Multi-pcb support is planned for a future version of KiCad. For now, you
can mark all the components on that sheet to be excluded from PCB. Sadly
it's not yet possible to do this for the whole sheet in one step, you
have to do it component by component.
Good to know, still this is not my top priority (just nice to have) - as
you said, one can think of workarounds.
I'm planning to focus on dissecting the "create-fresh-pcb" source code
at this point.... whenever I'll have time (not doing the actual pcb
design). Having this done will greatly improve my workflow.
Thenks again for quick response.
BE. Rafał.
Anyway. Should there be a chance somebody give me an idea where to
look into sources to work on feature (1), I'd be greatfull.
