Thanks so much I will look into those plugins and work on drawing the contours and smoothing them out to see how that looks, I don't quite need the mesh you have in the bottom pic because that's all supposed to be a flat concrete pad but the idea and methods helped me a lot and I will work on them in the area I need them at.

Ok as Ive said in my first post on this awesome site Im newer to the site but not to sketch-up as a program, I was a student a a local community college for residential architecture (recently graduated! ) so I have lots of experience with Auto-desk type products such as Auto-CAD and Revit Architecture too. My question is this, and its frustrating me to no end on why Im not smart enough to figure this out or that sketch-up cant do what i want/need it to do for me as usual. My question is, is it possible to curve a mesh/topo that is mostly square after i performed the stamp tool to make a flat opening for a walkout basement? right now it is straight up and down to the top of the non stamped mesh and i need it to curve down to a slope in multiple directions and i can picture it in my head, i can hand draw it, and can even think how i would do it with shaping it in clay with my hands but i cant figure it out in sketch-up and Im about ready to go nuts....if anyone as ANY input or advice on this or even just a plugin/script that will let me smooth the curve and slop the terrain I would love it...also if I can have it be something free since this is just a portfolio project Im working on to show potential employers what i can do for them in the best free program ever that would be great...thanks in advance if you can help me out!!!

Here is the attached screenshot of the area on the model Im talking about:

hey all im new to the sketchUcation site but not a newbie at sketchup, i do have a question about performance/system resources though. Ive created a topographic model from a DWG site plan and have been trying to use the FUR plugin script to make real looking grass and i have about half the model with grass and the file is now at 457MB and growing and sketchup is now about on its last leg everytime i open the file its using over 3.5GB of RAM and it crashes when i hit the 4GB limit for a 32bit program. sorry for the long rambling but my question is, is there anyway to fix this issue with the file? ive used other software like autodesks revit and never had this problem. ive even gone to hidding all the grass components so i can at least get sketchup to let me rotate the model....this is so frustrating can anyone help?
