Collab 2020: Modeling Heavy Equipment (Backhoe)

[Shawn Blanch]

 We’d need a BIG 3D printer LOL. I don’t want any less than True to Life Size

[Kent Trammell]

All this progress being posted has me playing catch-up! Here’s where I’m at after working a couple hours the past two Thursdays:

Still a long way to go. There’s so many details and pieces to model and interconnect. The diagram website is an absolute life-saver. I never could have figured out these intricacies with photos alone.

Like you, I’m running into similar subsurf pinch problems as @blanchsb, especially cylindrical shapes into rectangular shapes. I’ll be sure to discuss such junctions in the next stream.

Keep up the great work! The progress everyone is posting is inspiring 🙌

Yes Kent we will keep it up an thank you @theluthier 

[Adrian Bellworthy]

Nice work as always @theluthier.

By the way I have added my chassis/stabilizers file to the sheet but you have not resolved it as yet. I was wondering if there was an issue with notification. There is also no 0 in the Total XP column. Just saying, I want my XP. trying to catch up with @dostovel . Winner gets to drive the DOG first.

@spikeyxxx what do you mean by

 I mean your treads are going: left right, space, left right, space, etc. I think they should be more evenly distributed.

[shan jay]

Haha But you can’t go outside silly!

[shan jay]

@theluthier How can I join the tire and the tracks without disturbing the array modifier

[Shawn Blanch]

Next Question for the community regarding a potential “Clearance” issue (not a sale haha).

This should be easy to answer but somebody is going to have to “Give”.

If the loader arms are centered on the Bucket Mounts we will end up with very little room for the wheels to turn.

We either need to move in the Bucket Mounts to the Center More………..or Move The Wheels Out More.

Thoughts from the Pound?

[shan jay]

@theluthier I have submitted a file to Google Sheets 

[Adrian Bellworthy]

Looks a bit tight from  that  angle.

I think we have front and rear wheel steering on our DOG  wouldn’t need to much space but I did notice the tyres are slightly wider than the hubs but who knows which is the correct size

[Shawn Blanch]

Even though the reference never wins real life, it looks like the tires are correctly placed.

We don’t get a great view in the references on the main file for the Loader Bucket so I’m thinking they probably need to go towards the center more.

@pfbourassa what do you think? It shouldn’t be too much trouble to move your loader arm mounts in a little, correct?
I centered my assembly against those, so if we all decide that is the way to go then just tell me how much you move towards the center and I can do a straight shift on my assembly by the same amount.

Also the engine enclosure Aft-Side (towards the cab) is looking a little too wide I believe.
Thoughts??

P.S. That wheel well and axle-interface assembly looks amazing with x-ray turned on from above. I’m gushing. Can’t wait to see all of this stuff with some silky smooth subdiv going on.

[Kent Trammell]

@shanr That’s a too big of question to answer clearly here… In short you have to “sew” the tread geometry into base section of the wheel array and make sure the seam will tile correctly with each arrayed piece.

I will plan to cover that during the next stream so I can demonstrate thoroughly.

[Parker Bourassa]

Yeah, these are the separate objects, and when I cut holes it should be possible to slide the holes around easily.

[spikeyxxx]

@shanr Look at this:

There are gaps (spaces, the green lines)) between the treads (in blue). With an even distribution you should have : blue – green – blue – green,…and not: blue – blue – green – blue – blue – green,…

[spikeyxxx]

I am a bit confused about the tires…

Using a reference box with some known sizes (total height, stabilizer width, wheel base distance) and given the fact that the tires for this model come in 24” and  28”, I get something like this:

Something seems off, compared to the reference picture…probably due to the focal length of the camera…
