@@ -35,6 +35,7 @@ History of CLT changes to engraving and other functions it uses:
 12 Jun ver 208 Now scales correctly if orientation points moved or stretched.
 12 Jun ver 209. Now detect if engraving toolshape not a function of radius
                 Graphics now indicate Gcode toolpath, limited by min(tool diameter/2,max-dist)
+24 Jan 2017 Removed hard-coded scale values from orientation point calculation
 TODO Change line division to be recursive, depending on what line is touched. See line_divide
