I am trying to connect some surfaces with a group of curves, but cannot figure out how. I have tried creating a surface from the curves,but cannot match them due to trim.
I would think that the quickest way would be to make a patch surface for the roads (one for the part in the ‘valley’, one for the ‘parking lot’ at the top and a separate surface for the ‘stairs’) and then fill in with vertical surfaces (walls) between the landscape and the roads:
An alternative would be to make the roads as patches as above and then re-landscape the rest with new patches and using the original landscape as input surfaces for the patch command.
