Convert .s3d to SketchUp

Can anyone help on how to convert a .s3d file to sketchup please?

From the SketchUp Help pages: This might help.

thanks Dave
I’ve tried that but no luck. You directed me to .3ds
I’ve got .s3d
It’s what surfboard shapers use to design boards.

Took a quick look at the “shape3d” website .If you have the “shape3d” software you can export their models in .dxf or .stl format which can then be imported into SketchUp.
