Forum Archive › Collab 2020: Modeling Heavy Equipment (Backhoe)
Love this 😆
Your cab is tremendously improved @ketre! Excellent work.
I see what you mean about the rounded corners. Here’s a simple approximation of the shape
If your structure looks like this, with the magenta corner edge flanked by a cyan holding edge on each side, you simple need to slide the holding edges to the magenta edge and merge vertices by distance. Essentially removing the holding edges so the corner rounds over with subsurf:

For anyone interested in seeing some ‘bad topology clean-up’, I really enjoyed this: https://www.youtube.com/watch?v=NcEnCTooYfg
Thanks @spikeyxxx and @ketre
Wow, its from today and it will be continued! Thank you @spikeyxxx for the tip 👍.
No worries Artifact. I had to take a break this week too. I had a work project that demanding my creative juices and so I just took the “How to Create a Wall of Mailboxes” course from Kent to loosen up after a hard day’s labor.
I just saw what I believe is our DOG on the side of the highway on the way to take my kid to the gym. I’m heading there now to get some detailed pictures. Not sure if anyone is online but if I am able to get close I can grab some good shots of the main body. I may get some close-ups of the cab as well if I am able and I don’t cause someone to stop and chase me off haha.
@blanchsb if you can get some close ups of the chassis that would be great. Haha
Your kid goes to the gym? Please don’t tell me he’s like 10 years old or I’ll have to think about my life choices.
And consider that if you show the CAT Police our 3D model, maybe they’ll not only let you take pictures, but maybe even drive the real thing.
Skunk’d again! I’m getting closer to the mark this time though.
I saw the red safety bar and the enclosed cab and thought “This is it!” Well…….almost.
It was a CAT 430F (similar model but has some differences). Still I took my boy and we got some pictures and video. (some photos were taken by my son, and the long detailed video decided to rotate only a few seconds in…..thanks iPhone 😛 )
There’s plenty of reference stuff
There is still some decent reference stuff but it was raining hard so I didn’t get down on the ground or get too many close-ups of the chassis @adrian2301 The frame that holds the connection points to the loader arms is actually farther out than the engine enclosure. It looks like the enclousre tucks behind the chassis
@pfbourassa the bucket is completely different buddy. Sorry man. It doesn’t have any log-grabbing jaw like our dog.
@dostovel even the battery box seems a little different.
@ketre and and Cab Crew. The cab does seem to have more similarity as far as I can tell. The floor in the cab is flat (no steps).
@theluthier hopefully the backhoe pics are similar to your backhoe. The loader bucket is definitely different. I did get reference stuff and there is plenty there for hydraulic routing/etc.
Files are currently uploaded to a shared GoogleDrive Folder and should be available now. I separated the photos from the videos.
P.S. The team just upgraded to Level 6 Forum Masters!

Foiled again!
Thanks for the effort though
Excellent….. Definetly different, but certainly useful to know how things fit together, going to be similarities. 👍
Dude what in the world? Do you have like a freaking iPhone 21? The videos and photos look crisp and sharp as hell. Or maybe it’s because I have an iPhone 6… Now that I’ve seen what is possible, I don’t think I can look at my phone the same.
The tractor looks very similar, it may not be the same model but it’s great for the details that are probably 90% the same as the model that we are doing, plus I think we have really good reference for shading and texturing.
And your kid is probably like 5 and goes to the gym, that’s just great.
@dostovel My other kid goes to the gym haha. She technically goes to gymnastics but she has already surpassed my athletic ability and finesse and she is only 8. She competes on a team and we were driving her to gym for practice when I saw the Cat in the rain.
As far as the iPhone: it is the XSMax – the iPhone 10S with a McDonalds “SuperSize”
I love the picture quality of this bad boy but the rotating video drives me crazy. I still have yet to figure it out. Sorry if the video makes anyone sick haha. I’ve been dying to get some good pics with it for the project though because most of the stuff we see is pretty low res. But getting up close to one was still very educational. The fact that it was raining let my boy and I work undisturbed. I almost put him inside since the window was wide open.
The gas cap has a lock that you can put on it Omar. I’ll be willing to bet you can add that to your model if you’d like as that will be a common feature.
