    Hi all!

    I want to make a model of this railway snow-plow.

    I have a copy of the official drawing with contours/frames.

    From this I've created the shape below in Sketchup

    But when try to apply a surface (called Sandbox in Sketchup) to the frames Sketchup makes a mess. It doesn't seem to handle inward curved surfaces.

    Any ideas on how I shall create a surface like this? Is there any (free) tool better suited to this task than Sketchup?

    Thanks in advance

    If you PM me what you have. I can create it in different software. I will export it as a DAE so you can import it back into Skethup
