It is often convenient to use control characters to create drafting symbols in NX. Another option is to use ASCII codes, for example, alt + 0176 for the degree ° symbol.

Drafting and Dimensioning Symbols
Standard ANSI symbols for form and positional tolerance, material condition, etc. may be obtained by using one of the special control characters or numbers.
Put characters inside <> brackets.
| Control Character | Symbol |
| M | Maximum material condition |
| S | Regardless of feature size |
| P | Projected tolerance zone |
| O | Diameter (where O is a capital letter). |
| &1 | Straightness |
| &2 | Flatness |
| &3 | Circularity |
| &4 | Cylindricity |
| &5 | Profile of Line |
| &6 | Profile of Surface |
| &7 | Angularity |
| &8 | Perpendicularity |
| &9 | Parallelism |
| &10 | True position |
| &11 | Concentricity |
| &12 | Symmetry |
| &13 | Circular runout |
| &14 | Rectangularity |
| &15 | Total runout |
| ( | A left parenthesis 2 times the current character size. For reference dimensions, etc. |
| ) | A right parenthesis 2 times the current character size. For reference dimensions, etc. |
| + | A perpendicular divider with the size the same as the frame size of the form and positional tolerance symbol. |
| <#aN> | Quantity (where N is a number) |
| <#b> | Counterbore/Spotface |
| <#c> | Countersink |
| <#d> | Depth |
| <#e> | Conical taper |
| <#f> | Square |
| <#g> | Slope |
| <O> | Diameter (where O is a capital letter) |
