Exporting model with selected region

I have very beginner’s questions. I have made model with larger region of interest.
1:For a test purpose, I want to export only a small part of it. I resized the region of interest, but it exports full model. How can I export model with new region of interest?
2: Another question is about rotating model. I can view my model using keys 1-7, but how can I rotate it using mouse. I tried left/right/ crt+left/ crt+right, but no success.

Hi Shahzad

1:For a test purpose, I want to export only a small part of it. I resized the region of interest, but it exports full model. How can I export model with new region of interest?

set the RECONSTRUCTION REGION to a desired area and then use RECONSTRUCTION->FILTERING and select INSIDE or OUTSIDE the selection and then use APPLY.

2: Another question is about rotating model. I can view my model using keys 1-7, but how can I rotate it using mouse. I tried left/right/ crt+left/ crt+right, but no success.

press and hold the RIGHT Mouse button and move the mouse…
