    Fusion definitely has a free hobbyist / startup license. Install it for a free trial, then when the 30 day counter is up you’ll have the option to select a free 1 year startup license. You’ll be prompted to renew it yearly.

    Turn a 2D Image Into a 3D Model

    This is all done through the script, the Data Panel shouldn't even come into play. Did you follow the instructions?

    Take a look at Menneset's solution below.

    This particular image wouldn't give you the desired result because the script assigns height based on brightness. The darkest part of this picture is the text, so that will translate to a deep pit, and the lightest pixels are the cloudy parts in the water, so that will be the highest point.What you really need is what's called a height map that's less than 300PX X 300PX. Here's a link to some examples: http://casual-effects.com/g3d/G3D10/build/data/heightfield/

    For what you're trying to do, Fusion 360 is definitely the wrong tool. This is something you could do in Maya, 3D Max, Blender, or a number of other programs intended for motion graphics and animation.With many of those programs, you can do 2D - 3D translation as a tool within the program or with a plug-in. I haven't used Maya in almost 10 years now, so I'm the wrong guy to ask!

    Turn a 2D Image Into a 3D Model

    I'm glad you like it! The bottleneck here is resolution. The more pixels the picture has, the longer it takes to calculate. If you try and calculate an image that's much bigger than 300X300 at 72 DPI, it's going to take a LONG time to calculate.The other thing you've got to consider is that the more detail that's in the picture, the messier the 3D surface is likely to be. The script is just giving the surface a height at a point based on how bright that pixel is. More detail tends to give you weird results.

    Dude, for sure! I love your channel and I’m honor that you’ve included my work so many times.

    I haven’t tried it, but I honestly can’t think of a reason why it wouldn’t work. I doubt the Z axis relies in any significant way on gravity helping it out, and the bearings are snug on both sides of the tracks. The only issue would be that it would be a real pain to fixture the material upside-down. Every time you run a process for the first time, you have to watch it like a hawk to make sure it isn’t doing anything weird, and sometimes you have to pause it and add another hold-down point. I think it would mostly just be really inconvenient, but it would probably work.

    I always design things that are going to be 3D with 3D software. Even if the design doesn't necessarily call for it (stacked 2D panels in this case), I like to be able to get a picture of what the finished product will look like before I start expending materials and time.

    Just wait until your 30 day trial is up- you'll see an option to continue for free as a hobbyist / enthusiast / startup (I forget what they're calling it now). You'll be prompted to renew yearly for free.

    I don't see why not!

    What's a dynamo?

    I've got a 250V fuse on the AC input and heave gauge wires everywhere, but do you think I need a fuse on the DC input to the battery?

    Yeah, those are 3D printed. I could probably do those parts for about $200. PM me if you're interested.

    I just updated the list with prices. It comes out to about $210 not counting wood and 3d print filament.

    Yeah, I love that idea. I think the design would be a bit different, but it would be good to know what the solar panel options would be and how many you would need to charge the battery in a reasonable amount of time.

    As NightHunter300 said below, you could have a reverse setting! Just make a c-shaped part on a post so it can swivel back and forth. The ends of the C push the reverse switch on either side with a brake cable, just like you did with the pedal.

    Looks good, just keep in mind that you'll need support material to print this. More details about that in the next 3D printing class.

    Good work! The hoop is a bit large, you might have trouble getting it on a key ring.

    Looks good! That loop is going to need to be thicker if you want it to work as a keychain.

    Looks good!

    Lesson 3: Drawing in 2D

    Try adding some detail. where are the ports? Does it have sharp edges or are the edges rounded?

    I'd say you're doing pretty good with them! They just take practice. The important part is that you understand how to use them and are able to control proportions, which you obviously do.

    Not bad! Imagine how you might show that curved end in the 3D drawing-

    Very good! Try using construction lines to control the geometry. When you look closely the back-right leg is distorted inward, the left armrest would show up past the chair back, and the front left leg would be visible. If you drew construction line cages around it, you'd be able to easily position these elements.

    Lesson 4: Drawing in 3D

    That's actually pretty good. Try to pay more attention to proportions (the red ring on the top has a consistent thickness and it's wider than shown in the drawing). Also, construction lines will help even though it's curved.

    Remember, all the lines that are parallel on the object are parallel to each other on the drawing. The short edges, the long edges, etc.

    You're getting the line weight concept right, the weight is just too heavy for the size of the drawing. If you use a thinner pen to outline the spatial edges it will look cleaner.

    That's pretty good- very close to parallel and the proportions make sense. Try it again with the rounded edges and it'll be more realistic.

    Light and Shadow

    Good start. Keep practicing with construction lines- if you get those right you'll get straight, parallel lines.

    Good start, give it a try with a cast shadow.

    This is really good! That's a complex thing to draw. If you go over it again applying line weight, this will be a very good drawing.

    Looks like you're getting there, but you should practice with straight, clean lines instead of sketchy lines. They're better for manmade objects.

    You could, but depending on how you’re fixturing and how big your piece is, that can be really difficult. It would only really be okay with small pieces fixtures close to the open ends.

    Also, for a vacuum system has to have a hose coming down from above to avoid snags.
