jarrettr / stretch Goto Github PK

Has anyone tried running this in Kicad8.04? It does not work on my end. I can export to SVG but when I attempt to import back into Kicad, the text I added to the FSilkS layer in Inkscape does not appear.

When I attempt to export from Kicad to svg, the only thing that appears in the svg is some pads under 'Modules'. The F.SilkS does not appear. When I add to the 'F.SilkS' in Inkscape and use stretch to bring it back into Kicad, nothing changes in the PCB layout. I tried changing the name of the Inkscape layout to 'F.Silkscreen' to match what shows in Kicad layers to no avail.

Any ideas on what I am doing wrong?

Thank you,

The X/Y are XML fields that don't get converted

I cant export the SVG file from kicad when vias or coper zones are in the PCB design.

When a via is in the design it shows this error:

Exception on python action plugin code

When I installed and refresh this plugin, it shows "The soupsieve package is not installed. CSS selectors cannot be used."

I solved this issue by installing the required package to the KiCad python. However, is it possible to install all the required packages during the initialisation or installation stage?

I tried Stretch export on a sandbox example and it badly messes up text on output. Font sizes are wrong, at least one text object is moved, and a bunch are gone entirely. And several %R references are unresolved.

I'm not quite sure when this happened, but I noticed that the pads on one of my footprints are enlarged:

There is a workaround with right click -> update footprint:

It also shows up in Inkscape, but I imported/exported multiple times so it could've happened anytime.

With KiCad 8, arbitrary shapes can be connected to nets. Instead of the Inkscape hack with adding line segments to approximate curved traces, this can now be done natively.

The s-expression for the curves are like this:

	(gr_curve
		(pts
			(xy 66.4748 93.278) (xy 62.7248 90.378) (xy 64.2748 96.428) (xy 61.012077 95.482793)
		)
		(stroke
			(width 0.2)
			(type default)
		)
		(layer "F.Cu")
		(net 7)
	)

That ends up looking like this:

The four sets of points will end up looking like this in Inkscape:

Hi,

I'm using the Stretch plugin that can be installed through KiCad's plugin manager.
Importing back even the unmodified SVG int KiCad 8.0 gives me the following error:

Original pcb file:
kicad_test.kicad_pcb.txt

Stretch converted SVG to pcb:
kicad_test.kicad_pcb_imported.txt

Looks like the problem is with this line:
(generator_version 8.0)
The version number should be in quotes like
(generator_version "8.0")

The installation instructions mention this step:

Install dependencies using D:\Programs\KiCad\bin\python.exe -m pip install bs4 (but substituting your own KiCad\bin path)

Is the assumption correct that this needs to be entered into the windows console with administrator privileges?
What is the equivalent instruction for other platforms, Linux in particular?
Is the extension designed and tested in kicad nightly or only in stable?

SVG->PCB step ignores clearance, etc

In addition to making this plugin difficult to install, it also removes the ability to use the new KiCad plugin manager.

BeautifulSoup can be downloaded and included as a set of flat files in this repo, and in fact, it has been for some time, in the BS folder. That folder has been unused so far, though.

The problem with using it is that Python embedded in KiCad treats relative path imports really strangely. I attempted to get this working last year for a little while, but it was tricky, undocumented, and wasn't necessary for the minimum viable product.

Trying again to figure this out is becoming a higher priority now.

Whoops.

Dragging the layer in the Inkscape XML editor back into proper order fixes this, but not ideal

Thanks for the plugin! I just installed it in kicad 8.0 from the plugin manager. After setting up bs4 (ie from #36) I tried to export one of my boards to SVG and get the following exception.

TypeError: can only concatenate str (not "list") to str

Here is a screenshot of the error message.

I am considering extending the tool to include DXF round trip translations along side SVG, as the formats and conversions are similar. Would you be interested in having it added to your repo if I go down that path? If I fork, both efforts may have less overall support.

When i try to fatten the beizer curves in inkscape this error shows in the log:

How can I fix it?

The show up yellow / same colour as edge-cuts or unknown layers

If something bad happens and Stretch generates a corrupt/invalid PCB, and then you won't be able to open it in KiCad. When you can't open it, you can't click the DOWN arrow, and can't generate a new, good PCB.

Current workaround is just to replace the PCB file with literally any one that works in your OS file manager so you can open it and hit that arrow, but it's janky.

A slightly better solution is to back up the existing PCB before replacing it with the newly generated one.

I believe this has something to do with missing plugins,but I could be wrong.

Kicad V6.0.9, Linux
Exporting PCB to SVG fails with an exception in file text.py at line 237:
if len(self.at) > 2:

angle += float(self.at[2])

because there is an additional parameter "unlocked":

(fp_text reference "S2" (at 0 4 unlocked) (layer "B.SilkS")

A line with an angle looks like this:

(fp_text reference "S2" (at 0 4 -45 unlocked) (layer "B.SilkS")

Changing the above lines to
if len(self.at) > 3:

angle += float(self.at[2])

seems to fix the issue.

Copied the contents of Stretch-master to my plugins folder
C:\Program Files\KiCad\share\kicad\scripting\plugins
however, I am not able to load the plugins (refresh does not see anynew items).
Care to provide a sample?

I was trying to install the dependency bs4 as mentioned in the instruction which gives an exception error as attached in the picture.

Can I install from the Cmd prompt(Python 3.8.5) like "pip install bs4" instead of "\KiCad\bin\python.exe -m pip install bs4 " ?
What is the difference?

When I convert straight line segments to curves then reimport to KiCad, they continue to appear there as lines with the same endpoints instead of curves. Is there a specific way to create a curved board outline or trace?

Just adding a net for now until I dig into it

Only output to SVG works in KiCad 6. Changes can't be imported. I get and assert error.

Where do I start if I wanted to hack in KiCad 6 support?

I may just be misunderstanding the workflow or something, but the documentation does say:

"Make your modifications. Bend some lines, draw some pictures, rotate some footprints"

So I tried:

• Export to SVG
• In SVG, go into F.Silk layer
• Draw a circle (using the circle/ellipse tool)
• Change some text
• Save the file
• In KiCad hit down arrow, close and reopen PCBnew window

The PCB appears with the text changed, but no sign of the circle I drew.

This almost seems to be a bug in BeautifulSoup, although it hasn't seemed to crop up in KiCad 5 at all. It also only seems to happen when stretching up, right after stretching down.

It's generated from base.svg.find('g', {'inkscape:label': layer}, recursive=True) in board.py.
layer is F.Cu or anything else really.

The base.svg XML triggers the packaged BS in isolation, without using Stretch as a plugin:

More investigation needed. This does not happen with system-wide Pip installs of BS4.

It would be great to clarify which version of KiCad is confirmed to be working.
