Frequently I want to shorten the length of the horizontal line of the weldment symbol, but cannot.  It does not seem possible to adjust this.  I've searched through ASME Y14.x, but could not find a stipulation for this line length.

     I don't NEED to adjust it every time, but sometimes it would be very helpful.  Why can I not adjust this?  I'd really rather not draw it, change the line weights, scale it, then copy'n'paste it (for every symbol used) whenver I need to change it a bit.

     Is this simply an ER for me to submit, or am I missing something?
