Is it possible to extend/reduce the frame of the view?
I was looking for that in the Option. but I couldn't find anything.......
Also, how could I set up the shape of the dimension's arrow to filled arrow, before I start dimensioning?
From my experience, the answer to your first question is no. I found it to be really strange as drawing will never fit perfectly in window in case one view frame is outside thedrawing area.
The answer to your second second is that there is somewhere a XML file where you could pre define all values and it will be taken I to account for all new drawings.
