@Rob Lopez Hmmm..couldn't get the video link to work. sry

@Rob Lopez Able to see the video now and I see what you are saying. As I am also pretty new, I don't have a ton of input for you unfortunately. But I inderstand how frustrating it can be in the beginning here. If you go to the top left of the program and hit the down arrow, then 'new file' (select yes to clear the scene)...does it still just provide you with a 2D surface? Hopefully someone else here knows that issue one off the top of thier head. On a side note...when you were trying to click on the little arrows below the commands on the side bar...they are not 'drop arrows'...instead you have to hold them and then it opens another side bar with the other options associated with that command.

Sorry, first time posting...I am working on the beginner tutorial from Nikita...it's the free one from his library on the Skool 'classroom' section. This is the 10th lesson of that tutorial and I am at the 11 minute mark in that lesson. The first screen shot is the result of his boolean cut. Then he proceeds to add some fillets to some of the remaining edges. But in the second screen shot, after I perform the cut...my entire body of the object is hollow. I am not sure how this is happening yet. I'll try to attach my saved project as well.

@Vyacheslav Kudrya thank you for the input! I will investigate when i get a chance to get back to the lesson.

I like PlasticityMastery but I think LearnPlasticity.com sounds more professional and makes sense for your style, from my short experience so far.
