thanks for the fast reply

i meant the size of the windows, ie - make the front top and 3d views big and the right small.. or even taking him off.. things like that.. to be fully able to custumize the viewports...

about the construction lines - i read the help file right after posting here ,its exactly what i needed its a great tool.. and you made it much better then what i suggested. :)

another suggestion, something that i remember from rhino.. cross sections curves..
they are pretty handy at making better loft results
