This is a remix of @Mrexcon 's Engineering ruler, I thought it was a fantastic idea but the lines separating the open slots for the dots were far too thin, and it was too wide to fit in my pencil case so I've made a few changes:
-removed the 3, 5 inch rectangles to save some width
-removed the ovals to make space for a little handle
- increased the height of the segments between the holes for the dotted line, in Auto desk inventor I put a ledge on each but I placed them facing the wrong way so you kinda have to draw the line away from your body which is a bit uncomfortable but still totally works ( oh and let the pen have a ~45 degree angle on your pen away from you when drawing the line to get best results)
-I rotated the T to remove some of the flexibleness of the ruler and increased the width of it so normal pen can fit between it - added a simple 1X1 cm cube and triangle just cause.
Anyway, hope you enjoy! and thanks again to @Mrexcon for the fantastic creation in the first place.
