Hi ppl, Recently I decided to design my own raft this year for the Guildford raft race. The raft will use pvc piping for floatation and my (and an unsuspecting friend) will sit on two bicycles which will power two paddle wheels. Anyway, long story short i thought it would be a cool idea to model it up in some sort of CAD (maybe as something to send possible sponsors to show what i am going to attempt to do if they give me a load of pvc hehe), and, was wondering what software is best to use? thanks ppl

what CAD package/software do you use?

Hi - I have been using SketchUp for a couple of years, and grown reasonably proficient in its use.  However, it's not very intuitive in terms of being useful when trying to sketch ideas, find correct proportions, squeeze or stretch items until they "look right".  Having always to think in terms of creating drawings from extrusion of 2d surfaces is not often helping creativity! So, I am interested to learn and hear about anyone else's experience of using alternative CAD software in light of my comments about SketchUp - what do you use?

Beginning with fusion 360, trying to CAD few already available objects, designing a soap holder dish.

Hello, I am a beginner with CAD and with fusion 360. I am trying to model out some already available items, I tried few solid objects which went well and to gain more experience I selected this soap holder/dish as shown in the below images. I am using a vernier caliper to get dimensions of the soap dish. But, I am not able to get it to design correctly since the object has too many curves and crevices, especially from the bottom view and legs for which I am not able to figure out a workflow. Can someone help me with planning out the steps needed to get the desired CAD. Unable to upload the partially complete .f3d file since files other than images are not supported in a question.

Simple Design and Digital Prototyping Software

Hi guys. I've been making some very simple mechanisms for a steampunk Instructables series I've got planned, and have been prototyping using cardboard and paper. This has actually worked really well, but I'm a fan of the digital realm, too, and was wondering if anyone could recommend some simple, cheap (ideally freeware) digital prototyping software to help me eliminate (or minimize) the paper and card phase? As I say, the mechanics are very simple. Cams, pulleys, levers, gears -- nothing more complex than bell cranks, linkages and basic drives. I think a scotch yoke is about as adventurous as it's got so far. So I'm looking for some nice simple software that'll allow me to build and test the mechanisms digitally, if such a thing exists. I've looked at the likes of Autodesk and Blender, but they seem like a sledgehammer to cure a headache. Even something that runs online in a browser, or an iPhone/iPad app would be good (I've played some physics-based games on the iPad that would almost be ideal if they weren't puzzle games!). Any advice? Cheers guys!

What 3D printers can do... and what they can't

3D printers have seen insane amounts of attention in the past year with lots of stories coming out about how amazing they are. How they can make replacement parts for anything that breaks. How they’ll revolutionize manufacturing. How everyone will have one and they’ll do everything that you need ever. Long story short, 3D printers are pretty amazing, but they aren’t quite the miracle on a stick that the hype is pushing them to be. So let’s sift through and see what there really is to get excited about right now. Consumer 3D printers AKA what most people will be using The 3D printing that’s available to consumers right now is fused deposition modeling or FDM. These printers build up a model layer by layer by extruding ABS or PLA into the build area. It’s basically a much fancier version of a glue gun. A tiny glue gun controlled by a computer, that is. These 3D printers typically run $1k - $2k, but smaller ones can be had for as little as $200. The MakerBot Replicator 2 is the most popular printer of this kind, but there are dozens of others to choose from as well. With some fiddling and work you can pretty much print any shape that fits inside the build volume. So if the printer can fit it, you can make it. That’s simplifying it a bit (OK, a lot), but that’s the idea, and it’s a very cool idea. After some practice you can learn how to design new things like jewelry, ornaments, or toys. Since everything is printed out you can customize any piece that you’d like. Take a couple hours to learn 123D Design and you’ll start to have new things to print out. That’s the power of 3D printing right there. You can quickly go from an idea to a design and then to reality. Your skills in making things by hand don’t matter here. This is why it’s so amazingly helpful to use a 3D printer for prototyping your ideas. I recently worked on a flash drive case and the first model took about 2 minutes to design. After that it was about 15 minutes to print out on a Replicator 2. Then I tested it and adjusted the design for another print. I repeated the process a few times and within 2 hours I had a file that I was happy with. This is even better considering that I only spent about 20 minutes of those 2 hours actively working. The rest was spent on other non-related work. All about the materials So that’s the power of 3D printing. With services like 3D Creation Systems you can upload your file and get it printed on much fancier machines with better resolution. There’s no immediate gratification, but you still get a high-quality print quickly and access to more materials. Even with this expanded selection of printing materials, it’s still a very limited selection. If we were just to look at all the plastics out there we’d be here for days. There are thousands of them and that’s just plastics. There’s also wood and metal and more beyond that. Each different material in this insanely huge selection has a different quality to it. I’ve seen countless people print out items in ABS or PLA and complain about how their printer must not be working since the printed piece doesn’t work like the original. But of course we can’t recreate every item out there with a couple kinds of plastic. It's about using 3D printing with other tools The key forward in using 3D printing is to use it as an amazing new tool of forming great pieces to work alongside all the other great items and materials out there. Why bother making a weak spring out of plastic when you can drop in a metal spring? So 3D printing isn’t everything, but it can be used alongside most everything. It can get us where we want to go so much faster than before it’s ridiculous. But it’s still not the miracle on a stick, not the only tool we’ll ever need from here on out. When the hype dies down we won’t be looking on at amazement at something being 3D printed, we’ll be looking at lots of awesome new things that were made faster with the help of 3D printing. And that is going to be incredible.

Extrusion plate in CAD

I have an idea that requires either machining abilities/tool access or CAD experience. A while ago, I found out something that was apparently common knowledge. Meat grinders with their blades removed can be used to extrude spaghetti. So I decided to look for additional pasta extruder plates for different noodles. There are no pasta extruder plates for standard meat grinders. You can, however, buy a glorified grinder and accessory plates or a dedicated pasta machine for top dollar. The marketted pasta makers at their very cores are the same as the meat grinders with the right plates installed. Obviously pasta dies/plates for meat grinders are intentionally not produced. The closest I could come was a garage sale extruder that looks like a plastic grinder with three dies. Big surprise, it doesnt work. But I modified a plate so it sort of works for a grinder. This worked as proof of concept. Would anyone be interested in helping to design CAD files to print pasta dies on Shapeways based on proper pasta dies? I don't know much about CAD, but it looks easier than the designs created by some folks on here. Basically disks with a dimple for alignment and specially shaped holes. admittedly, the hole depths would be the complicated part. Let me know what you think.

Any other engineers have trouble getting used to 123D design?

I'm wondering if anyone else who has experience with professional CAD software has tried 123D and finds it difficult to use. I have ~7 years of experience using Solidworks in a mechanical engineering and robotics context. I recently tried to pick up 123D for use with my home 3D printer and find it absolutely infuriating to use. It feels like working with oven mitts on. But, I see screenshots of very complex models people have made all over the place. So, I'm not sure if: - I'm spoiled from the use of "professional" software and need to lower my expectations for free consumer software. For example, I'm very used to full control over creating reference geometry like axes and planes, and creating everything from 2D sketches that are then extruded/revolved/swept (as opposed to 3D shape primitives) and having direct control over all of the dimensions the entire time. In 123D I find it difficult to do something as simple as create two rectangular prisms and put them a fixed distance from each other, or create a rectangular prism and then put a hole in it a certain distance from one edge. - If this is just a difference between Autodesk and Dassault software - e.g. if I was used to using Autodesk Inventor instead of Solidworks, maybe I'd have an easier time picking up 123D. - If I'm just being lazy/impatient, and need to watch more tutorial videos and give myself more time to pick up the software. So, just curious if anyone else has a similar experience coming from using professional software (as opposed to a maker/hobbyist who had never used 3D CAD at all before).

123D Design tutorial for technical parts with accurate dimensions?

I'm an engineer with ~7 years of experience using Solidworks (professional CAD software). After hearing about Autodesk 123D Design here on Instructables, I tried to start using it to design and print things with my home 3D printer. However, I'm initially finding it very frustrating to use (more detail on that in a minute) - and I'm not sure if this is just because I'm stuck in my ways with the software I'm used to, or if I'm just trying to use 123D for something it wasn't really intended for. To try and give some concrete examples - I understand that you can create 3D shape primitives (rectangular prisms, cylinders etc) and assign them dimensions when you create them. I also understand that you can create 2D sketch objects and define their dimensions. What I don't find intuitive at all is how you can assign the dimensions of objects relative to each other. For example, say I want to make a 10x10x1mm bracket, with two 2mm diameter circular holes that have their positions on the face defined by the distance from their centers to the edge of the bracket. In a parametric CAD program, that is very easy to do in a 2D sketch and then extrude to a 3D solid. In 123D, I understand that I can create a rectangle primitive and then put holes in it using cylinder primitives - but it seems impossible to define the exact location of those cylinders relative to the edges of the rectangle; also impossible to create a sketch with two circles in it and a dimension defining the distance between their centers. To give another concrete example: at the 4:20 mark in this video (from this Instructable), he draws a circle on top of an existing rectangular part, and then "centers" it by just dragging it around freehand and eyeballing it. Would it be possible to define the center of that circle relative to an edge, corner, or center of that existing rectangle? Or can 123D just not do that? What I'd like to see, if anyone is up for it, is a step-by-step tutorial (preferably in video format) for making some sort of "technical" part where the dimensions matter and it isn't sufficient to just eyeball it and drag things around. e.g. a bracket like this (exact dimensions don't have to be what I drew here, but you get the idea). All of the tutorials I've seen so far - including the official Autodesk ones - seem to just focus on eyeballing it/free-handing dragging parts around.

Using Autodesk Fusion 360 or other package to make Lids and other form fitting parts?

First off, thanks for all the great posts and Instructables, I hope to be able to add to the growing collection sometime soon with a few projects I need to document.   Recently I have been trying to figure out a good way to create form fitting shapes with decent tolerances for  PLA printing.  I am using Autodesk Fusion and Blender using Boolean CGI operations, specifically the  Cut / Difference option. to create a appropriate sized cap.  If you have a peek at the attached image, the top part (red)  was used as a tool to cut out a matching body from a smaller cylinder (blue).  In the real world If these are printed, the shape would never fit together and if you did, you could never remove them.   What I would like to do is alter the bottom half to shrink it's surfaces inward about 0.25mm to allow for the expanding of materials. Every time I've inquired about this on some other forums, the first response Is  'Just use resize' and make the bottom half larger.'  Great idea, but there are a problems.  The inner plate/cylinder and radius walls expand to be too large The height changes, leaving a gap between the two surfaces Any suggestions would be great. I believe there is a path using Differences / Intersect and subtracting that, but I've been failing to find a solution to it.  I have included the Example top as an STL file.  Thanks for any suggestions.  And No this is not for a school project. Just a hobbyist looking to understand CAD.

SInce so many of you are already discussing and sharing your projects here, I wanted to reach out and introduce the project to the Instructables community specifically. We think SketchUp users do amazing work, and that sometimes this work gets lost in the 3D Warehouse. If you're particularly proud of a model that you've turned into reality (using SketchUp somewhere in your workflow), we hope you'll share the project and the story with us here. And please, we also want to hear about the role that Instructables played in your project! Our plan is to collect the most compelling stories and feature them in a special showcase, so that people who are new to SketchUp can be inspired by the work of others.

Back in college we used to work with SolidWorks, so I'm used to making some simple work in that. Problem is they do not have trials anymore, and I can't afford such a program. So I'm looking for a nice free CAD program to replace it. - It should have 3D capabilities, to make it easier for me to understand what I'm doing. - Constraints, so I can define dimensions and features and have the other features adjust to it - Boolean and Splines support, but no need for fancy tools. - Drafting, to make the finished blueprint. It doesn't need any simulation, rendering, analytics, or management tools, and should, before anything else, be easy to learn. Right now I have found a number of programs, but I have no idea about how to figure out which is "better" for me. I will be testing them while waiting for a possible reply, so maybe I'll be the one to find a nice one :) But PLEASE don't hesitate to reply if you have any suggestions!

AutoCAD was the first CAD package I really felt comfortable using and designing in. I've since realized that part of being an engineer is being familiar enough with dozens of different CAD packages so that you can recognize which one is the best tool for the specific challenge at hand. Since I use a Mac, I keep a copy of Windows running under Parallels primarily for CAD packages. This is actually a pretty common theme with people working at the various Squid Labs-related companies. I could probably walk just a couple of offices down and see SolidWorks on a MacBook Pro screen right now.So, I'm happy to read that AutoDesk is asking for input on a version of AutoCAD for the Mac:Mac Fanbois Get their Wish: AutoCADNearly two decades ago, Autodesk abandoned AutoCAD on the Mac.
