[solved]smoothing

The problem is not clear to me.
You are talking about smoothing be off and it be high in Thea...

any mesh will be smoothed by our action, by using Smooth command or via the checkbox for that in the Exporter dialog.

The way to get flat faces or sharpen edges is by setting the edges to hard using the Hardness command in selection Edge mode. In this case, some automation can be achieved by using the Auto-Smooth command wich will do that to edges connecting two faces in a minimal angle (that can be customised using the RMB option)
