Well... Got you..
I think i need to sit on the same issue and get it sorted out ma own..
solved the contour problem and now model is looking good enough for 1st stage of the design...
can we push or pull the curved lines if any in the model...as i got an error while doing so..i was trying to put up the compound wall around the building blocks.. so i draped the line on the contour ..select the region in between the lines, but i couldn't pushed it as it gives the same error as above..
Thnks..
