I would like to create simple elevation in rhino and I would like to suggest for Make 2D to project all lines to clipping plane or CPlane as a new feature. All the time I need to move them to the right location. I also tried the Section tool plugin but it uses the Make 2D that suitable for elevations but same result. Unfortunately Section tool has not got sort of scope extension feature that would show the rest of the geometry beyond section line. 3rd try was VisualArq but it still suffering from performance issue. For bigger building “VisualArq start generating geometry” and it takes ages (3 mugs of coffee) to finish.
