Hello, seniors

I am a rookie learning shapr3D.  
Question) When I visualize after modeling, some faces are not generated.  
Please see the snapshot below. What is the problem?  
I am looking for advice from seniors.  
Thanks.

Hello! Welcome to Shapr3D,

Missing faces in the Visualization are the result of a broken model that has an opening somewhere. Can you please check the design in the modeling space for missing faces?
