Curved Window - Sketchup Tutorial

hi, I always get a bug splat doing this, I think it might have been the amount of component I'm trying to curve, can you help?

Hello! tutorial please on how to use the shape bender plug in if one of the objects/models in the building is not on the red axis and needs to use that plug in. Cause I can't use shape bender if the line and curve that I drew are on the green axis
