There isn't any way to change it right now, but there are some commands that alter it dynamically to adapt to smaller sized objects. Over time I'll be trying to increase the number of commands that use an adaptive tolerance but it can sometimes be tricky to figure it out when only some small portion of the full object is at a small size like just the radius of a tube where the overall full tube's bounding box is not so tiny.

Really? What process are you using that would get you to such a tight tolerance?

Yes, you can get that level by scaling it down as a final step rather than trying to model things at that small scale directly.

For some kinds of things the adaptive tolerance will actually let you model at that small size directly, but in other areas you may run into problems so it's probably generally better to not directly model at such a small scale and scale down as a final step instead.

Yup, you would just use the regular Transform > Scale command to do that.

To use the Scale command, select the objects that you want to scale, the click the Transform > Scale button. MoI will then prompt you for the scaling origin - here you can type 0 and push Enter to specific 0,0,0 as the origin point. Then you can enter in a scale factor - enter in 0.1 and push enter to scale to 1/10 size for example.
