Good afternoon,

I have got 2 lines in my layer. I would like to measure their distance autommatically.

I found the tool, which might be helpful. This is the v.distance algorithm in GRASS, as advised in the link below:

Calculating distance of point along line using QGIS

My data attribute table looks like this by far:

and I would like to have the distance for all of them in the Length [meters] column.

I tried the v.distance GRASS plugin, but the situation looks as follows:

I am getting an error:

Wrong or missing parameter value: Column name(s) where values specified by 'upload' option will be uploaded

and I don't really know what to do with it.

I found some similar problem, where the v.distance algorithm also didn't work properly,

GRASS v.distance in QGIS not working

but they suggest changing the code in Python section. Is it still needed?

Is there any way to autocalculate the distance for all line features available in the given layer?
