How do i do this, have wasted about a week now trying to do this, always an error. SW is about the most non intuitive program i have used in the last 25 years even the website is difficult to navigate, its like going from PC to apple, I dont want apple !

Just want to sweep the face, dont even care if i have to clean it up after at this point...  'Inventor' just keeps caling ...  At this point i may as well use sketchup...
