SVG loader

[maot0341]

I do almost all my design with Inkscape / SVG. So I needed a Plugin. And here you are. It's  working pretty well for me on Linux. Rich support for path and nested transformations as well. And it's FREE.

Detailed descriptions + source code + binaries:
GitHub (deprecated):  [/https://github.com/maot0341/SVG-Import/wiki]
GitLab: [https://gitlab.com/maot0341/SVG-Import]


Binary setup: unzip attached DLL in your CamBan plugin folder and restart application.

Cheers.

Hello

Welcome to the forum, and thanks for this plugin 

Tested on CamBam V1.0 - 64 Bits (Windows 7) ; works well !!

It don't work for me in CB 64bit with SVG from Illustrator.
Plugin imports 100 "Polylines" but every Polyline is only one knot

@pixelmaker:
For exact scaling we need all of this attributes in the svg-node (root): height, width, viewBox. Only viewBox was given. I added with and height and it works. Still some bugs, I see.

I needed exact scaling in my application. So it's this way.

Two Bugs (fixed):
 - SVG root node needs width=... and height=... attributes for exact scaling. (mandatory)
 - Missed implementation of [sS] path sequence (i.e. cubic bezier continuation), fixed in attached version.

Updates on GitHub upcoming.
Thx for this example. Stay tuned.
Work still in progress.

How about SVG export from CamBam ? that would be ideal for some of my laser jobs.

Tried it on CB 1.0-Linux and seems to work OK.

Hello

I tried gears created with this soft

http://hessmer.org/gears/InvoluteSpurGearBuilder.html?circularPitch=5&pressureAngle=25&clearance=0.05&backlash=0.05&profileShift=0.01&gear1ToothCount=0&gear1CenterHoleDiamater=5&gear2ToothCount=7&gear2CenterHoleDiamater=4&showOption=2

But it seems that the plugin fail on the line: (the index is outside the limits of the array)

<path d="M-1.9254079070592334 6.770190155071996  L-2.0179231814188405 6.58935 ...........

I attach an example file.

Can you have a look ?

Thanks

David,

I found the problem.
There is a debug test function that uses a loop based upon the length of an array. The array is initially based upon transforms which uses x,y,z (length of array = 3),  but later it's used to calculate only x,y, values (length of array = 2) so when the loop reaches 3 it crashes.
I'll get that fixed and post it here later.

Edit: Another problem.
Some numbers in the svg file are in scientific notation e.g. 2.4154872234042437e-16 and this is causing problems.

Edit: When saving an SVG file from Inkscape for example, use "Plain SVG", this seems to prevent scientific notation being used.

The only reason I have looked at this is because the original author last logged in October 2020.
If member "maot0341" returns I shall willingly delete this stuff in preference to any updates they provide.

I got the source from Github but can't be sure it's the latest one 

Three files attached.

David's "involute_gear_0_to_7.svg" saved as "Plain SVG" format from Inkscape.

Fixed SVG-Loader plugin, "Verbose", this leaves all the message text in place as the SVG file is being processed.
Fixed SVG-Loader plugin, "silent", all the message text is disabled to speed things up.

You can't have both installed so choose the one you prefer.

Hello Eddy

Thanks

Plugin Repair Express 

Works OK with the "plain" file you provide, but there is a "broken" teeth with the file generated by the software (it has no settings to select plain mode) it's because scientific notation ?

Yes, Notepad++ for example can be used to edit the incorrect numbers.

re

Yes after some tests with other gears and editing the file with notepad, seems that all values that should be 0 (Y) are coded as X.XXXXe-15 or -16 ...

Bugfix in 1.0.14. File "involute_gear_0_to_7.svg" works fine for me now.
