General Knowledge

How do I type symbols into Eng-Tips messages? by drawoh
Posted: 4 Aug 20 (Edited 6 Aug 20)

Trying to show off drafting symbols in Eng-Tips messages is a pain, especially when we are discussing feature control frames (FCFs). The Eng-Tips text editor supports HTML character codes, and many of these are very useful. Instead of the HTML pointy brackets, the Tecumseh editor uses square brackets...

HTML non-breaking space: <&nbsp;>
Eng-Tips non-breaking space: [&nbsp;]

Basically, you replace the HTML brackets! There is a Unicode pull-down menu up there, but the following list is more complete.

General Text Symbols
Non-breaking space: [&nbsp;]
Non-breaking hyphen: [&#8209;]
emdash: [&mdash;]
Euro: [&euro;] €
Yen: [&yen;] ¥
Pound Sterling: [&pound;] £
Cent: [&cent;] ¢

Greek
Alpha: [&Alpha;] Α
alpha: [&alpha;] α
Beta: [&Beta;] Β
beta: [&beta;] β
...
Ohms: [&Omega;] Ω
Mohs: [&#8487;] ℧

Scientific and Drafting Symbols
Degree: [&deg;] °
Plus/Minus: [&pm;] ±
Times: [&times;] ×
Divide: [&divide;] ÷
Diameter: [&#8960;] ⌀
Straightness: [&#9188;] ⏤
Flatness: [&#9189;] ⏥
Circularity: [&#9675;] ○
Cylindricity: [&#9005;] ⌭
Concentricity: [&#9022;] ⌾
Profile of a line: [&#9696;] ◠
Profile of a surface: [&#8979;] ⌓
Angularity: [&#8736;] ∠
Perpendicularity: [&#8869;] ⊥
Parallelism: [&#11005;] ⫽
Circular runout: [&#8599;] ↗
Total runout: [&#9008;] ⌰ Not very good.sad
Symmetry: [&#9007;] ⌯
True position: [&target;] ⌖
Centre Line: [&#8452;] ℄
Depth: [&#8615;] ↧
Counterbore: [&#9176;] ⏘
Countersink: [&#9013;] ⌵
Square: [&#9633;] □
Translation: [&#9657;] ▹ ASME Y14.5-2009 Section 3.3.26
Dynamic Profile: [&#8710;] ∆ ASME Y14.5-2018 Section 6.3.31

The official counterbore symbol &#9012 (⌴), works on Seamonkey, Firefox, Epiphany and Midori. It does not work on Google Chrome, Opera, or Vivaldi. Don't use this.

Thank you chez311 for some additions to the list.
