Hi

i'm kind of new to sketchup.. Im working on a landscape project with loads of curves and irregular shapes. i have 2 problems.. and i hope you guys could help me out..

1 - i want to create a C shaped bridge. Ive tried "follow me" but it kills the idea .. it doesn't stay leveled it tilts inwards or outwards.. SO annoying! i can't even get it to start where i want it to start! you have to walk up a step to be on the bridge and it ends tilted at a 45 degree angle with no sight of 1 of the corner..

2 - ive predesigned the floorplan and traced it on sketchup, what i want to do is lift some areas up, creating humps and bumps..and some down. ive created a simplified plan to give you an insight of the shapes im working on..

Hope someone could help me out..
