size of contour is too big

[rmendezb]

symbol of conection electrical an plumbing are too big and hide the objet

Hello.

I'm drawing in autocad MEP

mi drawing setup is:

units meters.

i did inserted (for plumbing and electrical) any equipment with terminal for conections and for each one of the conection there are one symbol (triangle with !)  my problem is the size of this symbol, is too big!!  and i can't resize it  , if i turn off his layer, all this objet is invisible.

The image attached: four viewports of my problem: different zoom on plan and 3Dview,

The diameter of this simbol is   0.10 meter

In drawing BAÑO.DWG insert WC, wall mounted lavatory and drain plumbing.

Thanks. I can't work with many objets, all them has its own symbol(s) for each conection!!!
