1,字符插入---参考WORD代码
In SOLIDWORKS, start your note annotation and type in 2122. Then highlight it and key ALT+X. The TM symbol will be there. (Hint: Look at the bottom of the symbol dialog box in Word when selecting the TM symbol on the Symbols tab. It will show its "code". When you enter the sequence and hit ALT+X, it will "cut" the code and replace it with its hexadecimal equivalent. Weird!!
