A super simple extension to simply output the length of a selected path or paths (straight or beziers), including the individual segment lengths and cumulative lengths.
Has been tested most on Inkscape 1.2 and 1.3. Should work on 1.1, but I recommend updating. Inkscape has improved so much.
Add the .inx and .py files to your Inkscape user extensions folder. You can find this by opening Inkscape Preferences (Edit-Preferences) and selecting the System tab. Restart Inkscape and the extension will appear under Extensions - Prickly Gorse - Quick Measure.
I plan to release more related extensions soon, which will all be placed under the Prickly Gorse heading.
Select your path (or multiple individual paths) and run the extension.
Shapes need to be converted to paths (Object - Object to Path).
I wrote this to assist with making sewing patterns for bike and backpacking bags. Bit of a shameless plug, but if you are interested in sewing your own outdoor gear without making your own patterns, check out www.payhip.com/pricklygorse for my sewing guides (some free ones :D ), or www.pricklygorsegear.com/tutorials-myog for my main website.
You can also donate at this link if you find it useful :)
The code is built from the quite a bit more complicated Measure Path extension that comes pre-installed with Inkscape. Huge thanks to the authors of those extensions, and everyone who has contributed to the Inkscape project as a whole. Support open source!
