HEY
I need to create surfaces as attached and I need your help. Please help me 
I didn’t get what I wanted with the patch command. Can I do this without using Grasshopper?
Hi @blgozkan
A place to start would be to use the HeightField command, which lets you use a texture to drive the height of a surface (see Help for more details). Attached is a quick example made with a random ocean texture grabbed of the web and modified in PS (added the “flat” part in one end). Texture attached.
EDIT: Textures can of course be black and white as well - doesn’t have to be normal maps!
