Straighten technical drawing - denzjos - 04-19-2020

I had a problem with a technical drawing, it was slightly distorted. The straight lines are not perpendicular. Using the gimp transform tools in combination with guides gives a good result but was a little complicated. Then I remembered a had the 'Align to path' ( plugin.
Creating two u-formed paths (blue and red on the images), placing guides and using the plugin corrected the drawing. I've drew the U-forms from left to right and chose a reference point left below the u-forms. A simple example shows how it works :

distorted :     

corrected :

PS: if the drawing is dimensioned, then one can use guides and rulers to get a correct ratio.

Really practical and functional.
Thanks for the tutorial and the plugin.  Path Perspective

Plugin will be in Filters - Distorts - Align to Path
