Rigid constrains are not rigid?

[Lucas_Cadklus]

Hello everyone, 

I am Lucas, followed a training for 3dsmax as it comes with the PDM Collection and it would be a nice addition to my company to know a bit about it  😉

In Fusion I made a dart, see below, which I want to render, animate more realistic with 3dsmax.

I exported the Fusion file as an .obj file and imported it in 3dsmax.

with MassFX and rigid constrains it should be possible to place the dart automatically on the ground plane.

Unfortunately the rigid constrains are not really rigid afte applying the gravity:

I hope there is an easier solution for this?

thanks in advance for your response

Lucas
