PRO ART Drafting Triangle, 8-inch, 30/60 Degrees

Perfect

This Triangle is a fairly good drawing tool. However, it is not absolutely precise at 90 degrees. A simple 90 deg line drawn by mirroring the triangle deviates slightly.

I'm a drafter and while I now draw with 3D modeling software I remember drawing all my blueprints by hand back in the day. We always used these fluorescent angles because when the light hits the edges the edges project a bright side. This makes it easier to see, especially when you want solid precise lines. I guess I gave away my old ones because I can't find them. Now, I'm starting to make my own designs in stained glass and once again I'm needing to make those solid precise lines as I did in the beginning of my drafting career. This angle fits the needs of anyone drawing precise working drawings and beyond.

These are always a solid tool for drafting. As an engineer/nerd I am pretty OCD about drawing straight lines and keeping my work organized and neat. These triangles are my preferred straight edge and the color really helps. I find the 30/60/90 to be more conveniently shaped than the 45/45/90 and the orange tinted one to be easier to see than the clear option. Overall A+
