I want to drop a LOGO onto a plane, but I want it to just drop and teeter - almost like dropping an anvil, but not spin or fall over. How can I go about this?

Hi David.
To avoid the bouncing, you can reduce the Elasticity of your logo.
In Workspace side of 7.61 you can constrain the physics sim to run in a 2D plane
by selecting one of the radio buttons: XZ, YZ, or XY. I do not know if there is an equivalent
option in Model / 6.6.

One thing you could do, is remove the rotation keyframes in the undesired axes after running your simulation. But
be careful to retain the rotation keyframes you want: the rotation (teetering) in the axis/plane you want.

yeah, I don't see how to constrain using 6.6 - there is no XY panel with the simulation that I can see...

Low elasticity should make a collision like balls of clay. High elasticity should be like pool (billiard) balls.

I've had some luck in 6.6/modelside physics using adhesion to stop unwanted movement but the perpetual spinning has baffled me. Remember how things spun with my Splododyne Explodiatory Explodolator?

I'll be interested too if any can tell how do the drop David wants.

I might be 'late to the party', but...have you 'set parameters of object as iron'?
Oddly enough, it's got an anvil on the icon!
Right click that icon and adjust the Elasticity down, and the mass up.
Tip: right click the sliders to get a numerical input panel.
Rotate the object slightly before you start the simulation.
Set parameters on both the logo and the ground plane.

If the ground plane object has incredible mass then it could absorb much of the energy from other objects without noticeable movement.
