This problem is extremely annoying. On page 138 Step 2, I have to delete unnecessary surfaces. So I do, but if I then try to Convert Polygon to SubDiv, it doesn't do it :

Error: Command polyToSubdiv failed

Such a problem at the beginning of the project is pure sadeness...... please Help !!

Hi.
I am not looking at that book now.
But I think you can increase the "Maximum Base Mesh Faces" In the Convert To Subdiv option window to something big.

Or, fix the nonmanifold geometry by cleaning up polygons.
