does enybody knows if is possible to copy from autocad dwg (a view or something) and paste in inventor .I mean in a drawing sketch from inventor but like a block , because i want to insert  in a drawing view a sketch from autocad . I did but my sketch lost all constrains and if i wanted to constrain what I imported it was really hard because there were only lines without any connection.My only solution was to move entire entity but it took me a lot of time because my computer worked very hard.
