Ok, I read my own post and I think it is not clear enough.
There is a command for level symbol in the drawings:
Using it, you can add a level symbol in the drawing, as the one that can be seen in the attached picture.
Now, I have to give the level symbol for approx 300 parts in the drawing, and it would be nice if it could be done trough the drawing style.
Or I can do it manually.
Then again - I can vacume the dust off of my drawing borad, and fill the rapidographs in... ;)
p.s. - what in the name of God have happend to the "input area stretch" in the lower right corner?! A few minutes ago I was posting a new toppic, and there it was... Is it not working after 18:30? I'll try again tommorow... ;)
