Reducing the bounce of the box may help prevent it from falling over after it's dropped. Here's an example:

'''
Press spacebar to enable physics and drop the box
'''

import viz
import vizact
import vizshape
import vizinfo

viz.go()
vizinfo.InfoPanel()

viz.clearcolor(viz.SLATE)
ground = viz.add('ground.osgb')
ground.collidePlane()

box = vizshape.addBox(size=(.4,2,0.4),pos=[0,20,8])
shape = box.collideBox()
shape.setBounce(0.01)

vizact.onkeydown(' ',viz.phys.enable)

If you want objects to snap into place after colliding try handling the collision event and then animate or directly place the object where you want it to go.

The problem is not that the boxes drop but the osgb i imported

The Heizung Attribute is a STL data i implemented and edited it with the inspector. The boxes i implemented work perfectly fine they drop and lay staticly on the ground after they fell but the heiz1.osgb (a picture of it is attached) just drops over and i dont know why it does that in first place when i enable the phisycs

Hey,

just a quick question to the topic above again.
I think i found the problem. Like the Screenshot shows, the center of gravity is at the down left front corner of the object. so i think the physics apply at that point and thats why the object drops so weird on the ground.
I found sth about the pivot point in the documentary which defines the the turn axe of the object. Does that point also determines where the physics apply?
So i just had to move the point in the screenshot to the center of the object and i guess the problem would be solved. I found the solution in the documentary but all these functions are not shown in my instructor, so my question is how do i move that center of gravity?
Sorry to bother you so much but thanks for the help in advance

Forgot to attach the Screenshot
here we go

The node.setCenter command will change the object's center of rotation. I'm not sure but it might also help in this case.
