Transform by Reference Line Numerically
I would love to see a "Transform by Reference Line Numerically" feature where user draws a line across an object in any direction, then is able to specify the size they want. This is helpful for raster images where there is no actual vector line to accurately resize to. I use embroidery digitizing software and this is a cool feature. Wilcom Software Transform by Reference Line Numerically.
I've included a screen shot of the Wilcom Manual to hopefully explain better than i can articulate.
Meanwhile there is the Orient Transform tool from the AstuteGraphics commercial plugins pack that can do it.
