Starting in March 2020, I began a large stream project to model a comprehensive, highly-detailed Caterpillar 434E backhoe. Please watch the first stream (first 3 minutes of abridged version at least) for an overview.
It's a straight-forward project of building a complex model over an extended period of time. The spin on the project is that I want your help to accomplish it! If I build some parts and you build some parts, we will finish this thing much quicker. Plus the contribution format will include reviews, the potential of having your piece(s) assimilated into the final model. Not to mention large quantities of XP are at stake 🤑
NOTE: This is an involved project reserved for Citizen members.
The general idea is that I kickoff stages of the project via live stream, which is typically once per month. For the time in between streams, you choose a piece of the backhoe and apply what you learned from the stream to that piece. For example, the first stream covered initial block out. So between stream 1 and stream 2, your job is to pick a piece and block it out.
This is the repeating protocol for each Assignment Period (between-streams):
I will reply to this thread after each stream with a [big] assignment post denoted by a 📣 emoji in the title. There I will clarify instructions about each Assignment Period.
We will centralize our collaborative communication between the streams and this thread. Ask any and all questions pertaining to the Backhoe project here.
I tried selecting them and recalculating Normals it didn't work. Had to go get supplies, sorry for the delay.
I didn't get Doritos 
dostovel I got some cookies tho.. :P

There's a mistake, that link leads to the older file, it's not the file of those screenshots. See, that's what happens when we don't get Doritos in our supplies. Always get Doritos.
That's so weird, sry I got potato chips extra cheezy. lol

I see a duplicated face here on the front center, there may be more. I removed it, and recalculated normals. And now it doesn't have that hole.
Ok, I found some of the culprits.
I turned off all the modifiers. If you select these faces and G to move them, you'll see they are not connected. That creates problems.
Be sure to have wireframe turned on, so you can select all the vertices and merge them, because you have X ray and you might not be able to select all the vertices.
Also if you turn "Face Orientation" On, you'll see faces with flipped normals. For some reason recalculating them doesn't work. You can do that manually.
There seems to be other funky geometry, if you select this vert and G to move it around
You'll see you have a flying face, I don't know the actual professional name for that.
But this edge should go all the way to his other end.
Omg, thank you so much !!! I kept looking to see if I'd duplicated...I need new glasses 
That face shouldn't go all the way down, it should stop at this edge.
If you delete it you will see there were faces down below, occluded by the large face.
Now fill the face and it reaches the edge it is supposed to and it stops.
Now it's all good. I deleted the bevel and solidify modifiers. They weren't doing anything there as far as I could tell.
dostovel The reason I put those on was because I heard Kent mention something about the paper thin not looking realistic.
Next time I'll buy you some Kale chips and turn you into a...buck tooth rabbit! heehee...
Ok I see, I remember Kent saying that. I mean the modifiers there were just making a mess of everything, that tends to happen when things are too bunched up together, you can do the walls and insides manually, just so that the result are cleaner.
@theluthier yeppers this is an awesome thing, you are doing here. There’s alot I don’t understand as yet. But seeing everyone’s comments makes everyone more real. The struggle is real for everyone...🤓
You know, you think you speak english until you see something like peer-to-peer. I think it has something to do with boats. I'm afraid of the ocean so I'm gonna skip that one, thank you.
dostovel peer = person but, I'd like to be a boat parked at a peer of some exotic Island.
A Pier is where boats dock. Peer-to-peer means between friends or equals. It means we are all helping each other without Kent needed to get involved too often.
Oh in my head it sounded like a boat trip was happening or something like that.
You don't want to live on an island, believe me. The sun, the heat, you open your bedroom door and you have the ocean right there and you think, is all that mass of water going to come rushing towards me today? and all the green gooey stuff, all the blackness at the bottom of it all, sharks, you can't move well, you can drown, salty, sand gets everywhere...
