When I delete the selected Symbol from the floor plan in Plan View.dwg，the corresponding quantity on System drawing.dwg will change automatically（or "re" fresh). Is there any way to achieve this?If you are able to achieve this, please contact me. I sincerely appreciate it.

Command COUNT can do this.

In the count window, click "Insert count field" button and insert a field. 

Then you can copy its content into a Mtext.
