Westcott Engineers' Protractor Ruler, 6", 15cm, Transparent (W-8)

Works well, good resolution. Using for replicating objects as 3D drawings in Fusion.

I'm a Math Tutor for Teens, grades seven through high school. I give this ruler to all of my students when I start with them. It has inches and centimeters, and a protractor. For most students, the clear flexible plastic works great. For others, metal is appropriate. I like the clear plastic bc it can be used on laptop screens too. Great tool! I use them in my home also.

This ruler is the most fragile ruler that I have ever held. I would not bother with it, as it can snap so easily.

Es muy práctica para subrayar libros por su resistencia y flexibilidad.

Hands down my favourite daily use ruler. I've lost one and replaced it with two more. Great for technical sketching in parametric & dimetric; perfect for drawing offset lines in perspective using the printed grid as reference, the ultra-fine grid makes "not hitting a reference point" nearly impossible. The ability to have a functional protractor and ruler, where lines carry out to the rulers edge is invaluable in a single tool, no guesswork or connecting the dots required. After reading some of the negative reviews- the edge is perfectly straight, hold it down with two fingers while drawing and you'll be just fine. No this isn't a heavy gage stainless steel, cork backed straightedge. No this isn't an architectural scale divider. No this isn't a super heavy duty tool. No it isn't a 30 cm straightedge (just as the product details spell out) This is a 10$, multifunctional piece of plastic. Yes it might arrive creased, just as any thin piece of plastic shipped in a paper envelope might; my firs one did- bend it back, or send it back. If I had to offer one criticism, it's that it may smudge your sketches if you aren't careful, but adding a lifted cork backing would defeat the purpose of a transparent ruler. Can't recommend this enough!
