Also just done this pics, now i just have to animate it..... And yes cams are out of sync. Was late in the night.

In the animation it looks like the #3 rod isn't moving with the #2 rod. Might be an optical illusion. Still pretty cool :)
 
#2 con rod is staying clocked at a 12 o'clock position while the rest are following a vertical center line path that the piston would follow.

I miss drawing in CAD. I was taught using Release 13 at ITT. I could draw just about anything in 3D solids, but we didn't have animation back then. The programs are just too expensive to have for just fooling around, but I wish I had one anyway. I went to school hoping to land a job drawing custom CNC automotive parts, but there were no jobs for that in central FL. I landed a good paying job with an aluminum railing company, but I got bored drawing railing posts for balconies and stair wells real quick.
 
If you want to get back to CAD, Autodesk Fusion 360 is free for hobbyist, etc. and is pretty powerful. It feels weird to me, mostly because SolidWorks is my daily.

Thanks, I'll check it out. I had the student version of Release 13 when I was at ITT in '98-99 and haven't messed with anything since then. I took to it fairly easy so I think I can get into the swing of it in short order. I looked into Solidworks free trial not to long ago, but couldn't figure out how to use it and now I get unlimited emails for upgrades. Oh boy lucky me.

well spotted. #2 rod isnt running up and down like it should. well spotted. Thanks Ill fix it in next vid with the cams running

Running SW 2016 version. I tried going back to autodesk few mths ago but was lost. KeyShot 7 dresses up the pics quite nicely aswell

Yeah, that would have been a big change, from R13 to SW. From pure Boolean operations to feature based parametrics. Maybe also changing from the command line interface to clicking on menus and toolbars. I briefly used R13 solids for work. I'm told it was harder to use than R12 solids. I hear in R12 (and recent releases) you can move a hole by the grips instead of filling it in and making a new hole. Once you get the swing of parametric modeling, you'll rarely want to go back. In SW, did you get as far as figuring out controlling the geometry with constraints and relations instead of placing the geometry directly?
 
I downloaded the free 30 day trial and will go through the tutorials. I miss using a command line and tool bars simultaneously as it let me place my measurements for size and offsets while I picked where it would take place with the mouse, but I'm sure it will come to me. It's been so long I forgot most of it anyway, it just felt weird trying it out by myself. I wish I still had a desk top PC instead of a laptop.

It took me a long time to get over losing the command line. I do what I can with hotkeys and shortcuts, but I'm not sure which his ultimately faster. Maybe not the command line.

It didn't take too long to give up placing geometry precisely. I let the constraints and relations handle that for me now. In fact, when I do have occasion to place geometry manually, it feels weird, like it's unreliable. Using relations may feel like extra work, until you can change one parameter and update a whole design that would have taken five hours manually. That's when it clicks, I think.

We were taught at MMI to draw in actual measurements, because everything we did were destined to be blueprints printed to scale with all the measurements for the production of whatever discipline it addressed. I really enjoyed going there, we had to do manual board drawings and CAD drawings. It rotated, three weeks on the boards and three weeks on the computer. It got to the point on the computer that everything mechanical, I'd do in solids to pull all my measurements and views.

Mind if I ask what you use CAD for?
 
It was, but I was hoping anyone would chime in.

I went to school to give me a new career path 20 years ago, but the only jobs in central FL were architecture(not really well paying, but abundant) and power companies(boring). I took a well paying job offer with a small family run aluminum railing company that was a 45 minute to an hour drive one way. I got bored with it fairly quickly(still architecture). I already had a job with special needs children for the last 10 years and decided to stick with that for another 15 years. I don't regret my decision as that was a fulfilling job, but I wonder where I may have been financially if I had went in a different direction.

If I lived somewhere else it may have been a different story. I wanted to work on prototype and custom items for the automotive aftermarket, but it seemed as the majority of that work was in Cali and my wife had no interest to move away from her family. Now that I'm into bikes, designing parts for them may be a way to do something on my own. I have a neighbor that has a CNC business. So it may be something to look into. Maybe some custom parts for vintage bikes similar to what can be found for late model bikes.

I just took a look at your portfolio. That's what I'm talking about. Very nice work.

I also see you fixed your animation. Looks awesome. There could be money to be made in technical illustration.

My day job is designing fixtures for CNC mills. Mostly 4 and 5 axis verticals. I generally use SW for all my hobby work on the 3D printer too. It's fun designing for a different manufacturing process and experimenting with other kinds of modeling.
 
Thanks Dogma and gsrick, im getting closer to retirement so any extra dollars be nice . But we all say that.
