If you dont mind me asking, what is your profession? I would surmise graphic artist?

No, I'm not a graphic artist. I am a design engineer in the automotive aftermarket. I design 4wd related components. This is a functional engineering model. Solidworks has built in rendering software that lets me make it look more realistic.

Absolutely amazing!!! I've been using SW for 10+ years, I'm not even close to being able to do something like that. Did you 3D scan each part to give you point cloud to model around?

[Jeff/Illinois]

Very, very nice! Well done!

nomadpsd, did you use the Ford Engineering prints to construct the components, or did you reverse Engineer the parts by measuring them?

Mostly Reverse Engineered. I measure and use lots of pictures. Here are a few overall for reference.

nomadpsd, have you applied the animation feature to the solid model? If so, do you think you can make a youtube video available?

[Harpkatt]

This is so good. I'm interested to know what parts you are designing.

[Bill Cilker]

Very nicely done.

[KGBnut]

That is very impressive.

Here is a shot of the internals and a couple section views.

Great stuff, Thanks for sharing.

Wow - Super nice.

That's beautiful, nice work! From an "old school" guy (remember linen and India ink ?) that kind of rendering seems like magic.

Excellent - Solid Edge user myself. Don't think work would be too impressed if I started modelling Model A parts...

Joe B - vellum and Rotring pens when I started.

@nomadpsd
Did your model ever get converted for 3D printing? I sent you a message.

Thanks,

Wow, great, outstanding job. I would love to get my fingers and mouse pointer on the Step-files. Are you thinking about making them available by sharing or selling?

Nomad, I used SolidWorks for years to design manufacturing equipment so I know how much work you put into your model. Very impressive.

Terry Burtz did a similar SolidWorks model to design his engine. He modeled the cores for the casting using SolidWorks and gave them to the foundry. The model was also used to machine all the surfaces that needed machining using computer aided machining.

That is impressive, I did a lot of 3 d machining prototype work before retiring,We used Pro E was a good design tool, but not so much for machine operations.Biggest problems we would encounter was that if the model wasn’t defined in high tolerance, you would get poor machined surfaces.

In 1983 I left the Computer repair business (NOT the tiny PC but IBM mainframes) to work at a small company that made small Plastic Injection Molded parts.

These molding machines were multiple cavity molds to make more parts with each machine cycle.

Anyway the guys had been working on one multi cavity mold for almost a year and were about ready to start machining the mold with a 4 spindle CAM milling machine.

Art Woodward was working out final bugs in the mechanical drives for the ejector pin cams and water cooling for the mold to eliminate warpage of parts when the mold opened to eject the parts.

The Graphtec 2 megabtye CPU had an IBM 3330 200 Megabyte disk drive and we backed up the data a few times a day to an IBM 3420 clone 1/2 inch tape drive ( before 3480 Square Tape drives really caught on).

One Monday morning when Mark started up the Graphtec machine the screen was totally BLANK ... All of the work was GONE! Nothing!

Went to the backup tape and loaded it on to the 3330 disk.

After Machine IPL the same problem!

Mark was trying to figure out what to next when he noticed one small dot (1 or 2 pixcels wide) in the center of the CRT display.

After some discussion somebody suggested to try Zooming IN by 1000 times in that Dot.

The dot got larger but was still just a large dot...

How about trying to Zoom 1000 times again?

Then the whole job appeared on the CRT !!

Some how the whole job got Zoomed down to 1,000,000 times.

That was a case where "Thinking outside the box" really paid off".

After that we did many more backups, tested each version on a spare disk drive after backup was complete and kept Multiple generations of backups.

This was in the days where disks had a removable disk pack that mounted on the spindle)

Impressive. I have a 3-d printer, that is a small one, just to get someone started. I have never used it. Mine you load your file onto a USB, attach it to the printer, go into the LED screen and print from there...I guess.

I'd like to learn how to do it, to make novelties for my desk, small pars for my car like visor clips, ashtray knobs. This seems like welding - not that hard but you need a buddy to work with you a bit to get you going.
