I would love to see a video on creating a model of a vehicle (preferably car or truck) with Curvy3D. Your last video on a spaceship was very disappointing and very awkward to follow. With the 4 viewports being active it was difficult to know which viewport to watch. Also your space ship is not what I would consider hard surface vehicle.
I had a go making a truck in Curvy. I made very slow progress using Slice by Curve to cut out each area of detail like the windows, bumper and lights - then thickening each part. Overall the car body is a tricky shape to make in Curvy.
For research I looked up some other tutorials on cars and found this one. Several hours of modelling in Blender - mesh modelling gives you tight control over the shape of the mechanical parts and bodywork, and is much more suitable for the job than Curvy.
