i have not updated it to work in rhinoCommon. if you check this post on the first page, Santiago Diaz posted a brep only contour script. i will update my script when i get a second but the biggest problem is that there is no longer a contour function in the new rhinoCommon, so you cannot pass multiple geometry types, there will be a separate input for each type(mesh, brep, curve). i asked to have it added back into the sdk but it has not made in in as of yet.
