Cubit 15.7 User Documentation
The accuracy setting of the ACIS solid model geometry can be controlled using the following command:
[set] Geometry Accuracy <value = 1e-6>
Some operations like imprinting can be more successful with a lower accuracy setting (i.e., 0.1 to 1e-5). However, it is not recommended to change this value. Be sure to set it back to 1e-6 before exporting the model or doing other operations as a higher setting can corrupt your geometry.
