I have a symbol on a mechanical drawing that I can't identify. It is a circle with a slash through it. What does it represent? The drawing is dealing with measurements in mm for length/width etc.
Thanks for [Ø] and [±]. I always wanted to know how to do those.
Please note everyone, that on the TGML preview page, there is a "Click here" that shows you all sorts of TGML codes, not including the ones above. TheTicks values work nicely. Also, you can go to
If you click on the 'Process TGML' link when making a post, then click on the 'TGML Character Entity Reference' link in the window which opens up, the available special characters are shown. You can insert them in the way you would insert a smiley.
Can I have a star?
