I want to get things at accurate scale. How do I measure things. I was able to figure out how to make a line and get the length of it. But the number 1.643. How do I know what units of measurement that is?

Measure SOP. It's in meters.

Does Solaris also meters? I exported a usd out and measured in Maya I got the same measurement in maya with the centimeter settings.

There is no consistent notion of units in Houdini

Some imports/exports wrongly use hip file settings, which is actually meant just for DOPs and in my experience shouldn't be touched or relied on

But other than that it's just units

Ahhh, ok that makes sense. Thanks for the heads up on all of that.
