Issue:

I'm trying to build a Plane, but I get the error: "Axis length can't be less than zero".

Applies to:

• nTop 3.9.3

Cause:

This is happening because there is a vector that is created which is [0,0,0] that is causing the error. An example of how this can occur is shown below:

Solution:

Remove the vector which results in the [0,0,0] cross product.
