Exporting ListPointPlot3D to 3D file?

I am using Wolfram Engine 12.3.

I made a ListPointPlot3d and I want to export it to a 3d file for viewing. The plot exports properly to a .gif file (it’s rasterized). When I attempt to export to a 3d file it’s telling me there is no data to render.

In[142]:= Export[ "d://output3d.obj", ListPointPlot3D[ outputPoints ] ];                                                                                                
Export::nodta: OBJ contains no data that can be exported to the OBJ format.

How do I fix this? the goal is to have a 3d object constructed out of the 3d points rendered from ListPointPlot3D.

this is what the plot looks like when exported to a gif. There are no solid surfaces, only lines. It’s a Complex Trig plot but I don’t see how that could effect it’s 3d rendering.

thanks.
