Im starting here a little window frame experiment.
I created the outer shape of the window (rectangle) and a small profile shape.
Now the ideal thing would be when I sweep the profile curve around the rectangle to have a nice looking frame but I get the shape in the right corner:-(
I could avoid this by puting in each corner a profile shape and rotating it 45 deg. and then lofting but any way this could be made with this single command.

I tried this making In AmapiPro wich even beated the Rhinos workflow because you hadnt even need to rotate the profile shape 45 deg. just a sweep.
Any chace for MoI here to get in the lead?:-)
