Despite loving Sketchup for its ease of use and speed, I am doing the bulk of my jobs using Blender, as it has so many features that I feel I need. I am getting used to its interface and tools slowly.
"There is no limit for improvement" das ist eine zutreffende Formulierung für diese wirklich hervorragend schöne Arbeit Alvis!
[did you use Flowify for the shown bending?]
