imagine your writing a report or a letter to a friend, and you are telling them its really cold outside and write…
“the 25mm diameter thermostat reads 3 degrees centigrade and it has an accuracy of plus or minus 1 degree centigrade”
ALT Codes for circled number & letter symbols (Enclosed Alphanumerics). Below is the complete list of Windows ALT key numeric pad codes for circled number & letter symbols, their corresponding HTML entity numeric character references and, when available, their corresponding HTML entity named character references. The CATIA Symbols font (not in the above list) contains the symbols from V4 fonts. For each of the Bitstream fonts, the following files are delivered in the location referenced by the CATFontPath variable: In the Postscript folder or subdirectory:.pfb,.inf,.pfm,.afm; In the ExtraFiles folder or subdirectory:.ttf.
while its grammatically correct, its can be written more accurately and faster as…..
“the 25mmØ thermostat reads 3°C and has an accuracy of ± 1°C”
OK, so the example above may not be realistic, but you get the idea, using special characters can reduce the amount of typing you have to do, and gives your document a professional appearance. there are 2 basic methods for inserting special characters THE HARD WAY and THE EASY WAY.
The Hard Way
- Click the WINDOWS / START button
- Navigate to Accessories
- Navigate to System Tools
- Start the, Character Map,
- Find the symbol you want to use
- Copy it to the clip board
- Paste it into your document.
- Repeat items 1 to 7 for the next symbol
- YAWN…..
The Easy Way
print out the list below and keep it handy for quick reference, it wont be long before you don’t need it any more. the shortcuts below are available to most text editing software packages but there are a few exceptions.
The {ALT}+Number Method
The most important thing to remember is that the following tips only works on a full size keyboard with NUM LOCK active, the rest is easy……
to get the characters defined below simply use the LEFT HAND{ALT} key and type the numbers specified using the number keypad on the right hand side of your keyboard.
Ø = {ALT}+0216 (diameter symbol)
° = {ALT}+0176 (degree symbol)
± = {ALT}+0177 (plus & minus symbol)
® = {ALT}+169 (Registered trade mark symbol)
? = {ALT}+23DA (Earth / Ground symbol)
The Word Auto Correct Option
Microsoft Word, Excel and many other office type applications are able to produce the following characters by using a special key combination that is easy to understand and learn. The only thing to remember is that the typed test will not chnage to the required symbol until AFTER you press the {SAPCEBAR}. for example if you type “(C)” and press {SPECEBAR} you will get © (copyright)
© =(C)+{SPACEBAR} (Copyright)
® = (R)+{SPACEBAR} (registered Trade Mark)
™ = (TM)+{SPACEBAR} (Trade Mark – Unregistered)
¼ = 1/4+{SPACEBAR} (Quarter)
½ = 1/2+{SPACEBAR} (Half)
¾ = 3/4+{SPACEBAR} (Three Quarters)
If you know of any more please let me know, I will add them to the list and credit you with the find.
GD&T Symbols Reference Guide from Sigmetrix
In geometric dimensioning and tolerancing (GD&T), a unique set of GD&T symbols are used to define the relationships between part features and measurement references. Designers and engineers utilize this international language on their drawings to accurately describe part features on the basis of size, form, orientation and location.
Are you looking for GD&T training? We teach GD&T so every team member:
- Understands what the GD&T means
- Understands how the GD&T works
- Understands the effect of the GD&T on product function, manufacturing, inspection, and assembly
- Understands the effects of the GD&T throughout the product lifecycle
We ensure that your design, manufacturing, inspection, assembly, quality, and service personnel and your suppliers understand GD&T as needed to be successful and produce the highest quality, lowest cost products possible.

| GD&T Symbol | Control Type | Name | Summary Description |
| Form | Straightness | Controls the straightness of a feature in relation to its own perfect form | |
| Form | Flatness | Controls the flatness of a surface in relation to its own perfect form | |
| Form | Circularity | Controls the form of a revolved surface in relation to its own perfect form by independent cross sections | |
| Form | Cylindricity | Like circularity, but applies simultaneously to entire surface | |
| Profile | Profile of a Surface | Controls size and form of a feature. In addition it controls the location and orientation when a datum reference frame is used. | |
| Profile | Profile of a Line | Similar to profile of a surface, applies to cross sections of a feature | |
| Orientation | Perpendicularity | Controls the orientation of a feature which is nominally perpendicular to the primary datum of its datum reference frame | |
| Orientation | Angularity | Controls orientation of a feature at a specific angle in relation to the primary datum of its datum reference frame | |
| Orientation | Parallelism | Controls orientation of a feature which is nominally parallel to the primary datum of its datum reference frame | |
| Location | Position | Controls the location and orientation of a feature in relation to its datum reference frame | |
| Location | Concentricity | Controls concentricity of a surface of revolution to a central datum | |
| Location | Symmetry | Controls the symmetry of two surfaces about a central datum | |
| Runout | Circular runout | Controls circularity and coaxiality of each circular segment of a surface independently about a coaxial datum | |
| Runout | Total runout | Controls circularity, straightness, coaxiiality, and taper of a cylindrical surface about a coaxial datum |
