Best way to get these cushions? Freehand line drawing or shapes? need help!
You can do this sort of thing in LO. This was done using just the 2-point arc tool. If you have the image imported into LO you can use it as a guide. I just eyeballed it quickly.
Turn off Grid and Object snapping in the Arrange menu.
I still think it would make more sense to do the modeling in SketchUp and import scenes into LayOut.
