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' (ob-align.py) plugin. https://www.gimp-forum.net/attachment.php?aid=275 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 : [attachment=4218] corrected : [attachment=4219] PS: if the drawing is dimensioned, then one can use guides and rulers to get a correct ratio.
