I have two requiest about a symbol of weld for JIS(Japa Industrial Standard).

1, It is not enough about kinds of them. 

 For example, Sopt weld (resisted) is not exsit. A circle is on the baseline through the center of it.

2, Please let the word of symbol to be the same as JIS.

3, Check-box is useful. I will check it and appear in a pull-down menu when number of symbols are too much.

How to request to 3ds?
