Do you mean "Not working right"?

 

 

I just tried it in v16 and it doesn't work there. Could there be something wrong with the Project?

[robcat2075]

I had slightly better luck when I turned the normals of the trough to face in, but it still didn't stay on top of the trough all the way down.

[johnl3d]

Meant for it to be a question anyway I tried various ways all with weird results it might be that newton does not react to a ramp

[robcat2075]

There should be a way to make that work.

There should be a way to make that work.

 

Make sure the normals are facing the right way and that your ramp has a real thickness. You can just extrude it and it should work at least in a better way.

I attached the modified project, which works much better. I am not sure if it works perfectly because it is not spinning at the beginning, but it reacts to the underground in a better way.

 

See you

Thanks will try when at home

[johnl3d]

That worked better but the ball does not roll and that is what I was hoping it would do ..Thanks for looking

[robcat2075]

Is it because the bone is not at the center?

[yoda64]

Robert has hit the point, the real problem here is , that the model bone is not centered at 0,0,0 in the model . The model rotate around the center of this bone .

The second problem was the false normals for the grid.

I have attached a corrected project file

newtonfalltest_corrected.prj

[johnl3d]

Thank you ...now we can roll out a snow ball or two .....

 

 

 

quick test of idea

Nice one John!
