AutoCAD 2D Design for engineers

Hello everyone, My name is Yarin and I'm a civil engineer. several years ago when I just started to work I needed to learn many of the principles and commands of AutoCAD by myself, because there were no friendly guides over the internet, and nowdays new workers expirience the same thing. so I'm here to offer my help and knowledge. NOTE: i have no expirience in progreming, only design. Best regards and good luck

AutoCAD 2012 for 1:1 3D model making/printing?

The title just about sums up my question. I am using AutoCAD 2012 to make 3D models for the intent of 3D printing. However, all the models I make in CAD are smaller then they are showing. For example, I draft a 5x5x5 cube, and export it as an STL. Then open in a a few different STL viewers, and the cub has shrunk down to about 2.5x2.5x2.5. Now, I can always just scale up my models to fit the needed size, but if I can get CAD to agree with me to make a 5x5x5 cube that will really come out to be 5x5x5, that would make things easier.  Also, as a precursor, I have changed the units in CAD to match my needs, but it the models are still coming out small

I'll turn your technical drawings into files for 3D printing. [$5 per part]

I have access to Autodesk Inventor Pro and I can convert technical drawings into 3D models that can then be printed using a 3D printer.  If you are interested, please email plans for a small test piece (cube or similar simple object) that I will draw and send for free to make sure everything is compatible. The most common filetype is .STL. I accept payments via PayPal after the model has been reviewed by the customer.

AutoCAD for Mac Survey

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. But now perhaps it is seeing too many sales lost to the likes of ArchiCAD to architecture clients, NX to mechanical engineering customers, and SketchUp to designers. Autodesk marketing calls it "trying to stay in tune with our customers," and are asking Mac and AutoCAD users to fill out a survey. ..."

How do you make an Inventor assembly with parts that interact? Answered

Currently, I can use constraints to assemble parts, but when they are moved around, they simply go through each other. How can I make the parts push each other around? For example, I'm designing a paintball marker, and it has a body, bolt, trigger assembly, and various pins. How would I make the bolt catch on the trigger when it is moved rearward? How would I make the bolt go forward when the trigger is moved rearward? I'm using AutoDesk Inventor Professional 2012. Also, I have access to most current Autodesk programs if they are required.

Automatically laying out CAD parts for cutting (by hand, CNC, Laser Cutter, doesn't matter)

Hey, I am about to build a bike trailer. I planned the whole thing in Autodesk Inventor to see if everything fits and works the way I want. Now I have several parts that need to be cut out of a board of wood - Some are pretty complex, so I don't want to do it by Hand. Is there a program that imports my CAD files and automatically lays them out on a board (size and shape specified by me)? Would take a lot of tedious work off my hands and avoid stupid mistakes. Let me know if you know of anything :) Thanks! Michael

Batch check the integrity of AutoCAD? Answered

We need a way to batch check the integrity of a lot of AutoCAD files and need suggestions or recommendations.  These files have been recovered from a raw data image so many of them are corrupt and will not open.  The option to move any undamaged files would be extra beneficial. The only program I have been able to find is one called SmartPurger but it does not work as AutoCAD will popup with error messages on corrupted files and stall the process.  There is an option in SmartPurger to auto accept the popups but it does not seem to actually work.  Been Googling for a few hours and it looks like it somehow may be possible with LISP or Script programming but I've got zero experience with these things. Thanks!

Hello, just read through the first lesson, hopefully get it installed on my personal laptop tonight. I have had some experience with the 3D functions in AutoCAD, do you know how well AutoDesk made the software for crossover users?Also, a lot of libraries have 3D printers for use of members. They usually charge a small fee, my closest one charges by the weight of an object printed I think the min. is $5. They also require an appointment with the specialist, he is supposed to be able to give you instruction. This would allow you to get in without buying a printer right away.I am excited about the class, and look forward to getting some ideas into the printer!

Using "Phun" to simulate mechanisms

I'm not an engineer, and don't have access to Autodesk / AutoCAD, so I've been using Phun to simulate mechanical design.It's not strictly valid in an engineering sense, but it works pretty well for roughing out ideas. The polygons were created in Inkscape, then converted to Phun scenes with SVG2Phun. Some objects won't translate (like grouped objects), so it's necessary to simplify (hence the two images from Inkscape.)

Metal Cutting using CNC Router

Hi, I am wondering if a CNC Router can be used to cut 1/8" or less thickness aluminum. Although my shop is primarily a wood working place, I do get into some metal stuff at times (I have gas and electric welders, drill press, etc) and I am in the process of restoring a 1952 Piper Tri Pacer airplane at the moment. I want to design and build (I have AutoCAD 2011) a new instrument panel for the airplane as well as some other small aluminum parts. None of these would be more than 1/8" thickness material and likely not even that. Anyhow, I was wondering if I could install a milling bit in the router and use it to cut this lightweight, relatively soft aluminum. Does anyone have experience with that? Thanks!

Wheelchair mountain bike

Hi guys, I have an idea for a go anywhere buggy that I can use on mountain bike trails instead of my wheelchair. I have a very basic design of my idea and need advice on where to go from here. I have a very rough sketch of my idea. But I have no idea of how to use AutoCAD or do anything else with this fantastic little device. So I thought I would ask all of you guys for your input. In the attached sketch. The pink represents a rigid frame. The green is suspension. The black is bicycle tires appropriate for your needs. The blue is an adjustable net seating. And the gray is batteries and motors. However my son informs me that it is possible to put the motor in the hub of the wheel. Which sounds like an excellent idea to me! My idea is to hang the frame from the suspension above the wheels.  And balance the weight of the occupant(s) and the batteries. I think that this has potential for many other applications, but I just want to go play in the woods and the beach again!

CAD for mobile or desktop? Mouse or other? Answered

Is it really necessary to use the desktop version of CAD or CAD-like software or are versions designed for iPad/iPhone sufficient? I was also wondering about the pro tip to use a 3-button mouse, is that because at least one button should be programmable, in which case I have a Wacom Intuos Art version which has four assignable buttons, as long as one of them corresponds to a default left click, all remaining buttons can be assigned a single mouse or keyboard operation i.e. click or keystroke, a sequence of them or even opening an application or if you're willing to code it any AppleScript you choose which can then be used to invoke any other scripting/programming language. I also have ControllerMate installed on my machine which allows me to remap any single mouse or keyboard press or combination of simultaneous presses onto any other keys or buttons or executable command including but not limited to AppleScript or other scripting or programming language etc. I have also noticed that the only autodesk based mobile software that allows to generate cad designs from scratch is AutoCAD 360, can this be used instead of fusion 360, seeing as how fusion 360 for iPad seems to only allow viewing and editing but not creating a new 3D file.

Designing a Contemporary Computer Desk

Hello everyone in this wonderful community! I want to share something to see what you think about it! When I finished high school in February last year, my family gave me some money as a present. I put all that money into my new computer. However, I had no other place to put my computer than my work desk. I need this desk for many other things, such as airplane modeling, drawing, designing, soldering, and such. Therefore I have to get a separate desk for my computer. I always enjoy making stuff myself, so I thought that I could design my own desk. So, this is what I came up with. The desk I have designed has a contemporary, extravagant look, and is NOT designed to save space! It will be made of MDF and have a dark glass top. No drawers or shelves needed, except for the keyboard and the mouse. It will be wall-mounted. The MDF will be painted black. I have made the design in AutoCAD 2007 in 3D to see what it will look like, these are the renders I made, of the complete desk, of the structure, and of the pieces needed.  --------------- I am not sure of the thickness of MDF and glass that I should use, or if the structure is too heavy or too weak. (I have a desktop computer, not a laptop) Please help me with this part! --------------- If I ever build this, I will make an Instructable of it! Please take your time and say what you think of the design! I will greatly appreciate it!

Molding Aluminum: With Gravity Die Casting

It's expensive, untested and dangerous.The idea goes like this. Start with a coffee can foundry, possibly powered with Biodiesel or Propane. Then design a mold for what you want to build using Autocad or some variant thereof. After it's finished, send the design to a machine shop to have it built out of steel. When you receive the permanent mold, melt the aluminum and pour into the mold repeatedly and often.The idea seems like a good one to me, I'll be testing it soon enough using common screw clamps to keep the mold tightly secure.Has anyone here done this? The closest I've come to doing it myself is pouring into a muffin tin.The photo below is a picture of the results which was taken from another board found here, you'll need a login, the photos are located in the forum under Machining and Tooling.Give me a shout if you dig the idea.UPDATE 5/24/07It works! Using my Harbor Freight Mini-Mill I cut out pockets in two pieces of 1018 steel, each about an inch deep, and four inches across. I then cut inlets in both pieces and welded some scrap steel U channel on the tops of both mold sections to form a pool enclosure for the excess aluminum to collect inside of and stay safely contained.Then I lit the candle on my foundry and melted the aluminum while at the same time pre-heating the molds, (connected using C-clamps) in the oven. When the aluminum melted, I poured it and it instantly solidified. After about 2 minutes of running around in a panic I cracked the mold open. The detail level is incredible. Impressions made in the mold with a fly-cutter can be seen in the casting. The casting is bright, shiny, and seemingly devoid of any burs usually associated with unfinished aluminum castings.I'll provide photos later of the test mold and casting.

A Quest!

OK - first off, hello everyone!! I've not posted an Instructable for perhaps 4 years now, but I have done a fair few things in the intervening time (shortened life story to follow - if you just want details about the project, scroll down.) Not sure when, but in early childhood I started playing around with K'NEX. I'm sure you'll all agree thats acceptable for a kid of about 5. Several years progressed before I discovered the art of K'NEX weaponry - which led me to create my first ever (and widely crap) Instructable. My fascination for things that you have to put together to make them work has not faded - I have become involved heavily in the Greenpower Race Series for Schools (www.greenpower.co.uk, if anyone's interested - I'm Rob on the forum) and next year will probably be my last truly competitive one - I'm building the one for next year over the summer. Having looked for a couple months about what I can do next, I've come up with a bit of a foolhardy quest  that sevearl people have probably already done. The Project (hello, if you've just scrolled down) is to design, build and drive on the road an Electric, 2-seater, Hardtop Sports car with the following features: 85 MPH top speed (15 more than the Motorway limit), 500 mile range, flash charging capabilities, various mod-cons (e.g. a windscreen), some luggage spaces and a price tag of as little as possible. I'm probably going to be designing the chassis on a 3D CAD program (either Solidworks or AutoCAD) over the next couple of years, as well as getting enough money, sourcing parts, and designing the PWM (Pulse Width Modulation, controls how long the motor is on for in any given second) system. Here is a list of what I see as I need to do: Source electric motor Source batteries + charging system Design chassis Source parts for chassis - Welder, rear differential, steering components, bits of Aluminium/Steel (haven't decided which) box/tube. Build rolling chassis. Anyhow, I will be making an instrucable and will hopefully publish it once I'm done. The whole thing will consist of my entire design process and building processes. Everything from chassis stress testing to choosing what type of dials to have. Hope that was mostly interesting! Rob Hopeful Instructabler

Project Collaboration?

I'm REALLY bored at work at the moment and need a personal project to distract me. The problem with past projects is I often run into problems or lose interest and they fall by the wayside. I was thinking that if the project was a collaboration I'd be more motivated and could call on people with better skills than me. Anyways I'll propose a few projects, and let me know if you are interested. Or if you've got an idea, post it up. I'd love to do something robotics related, but m programming skills aren't great. I can use "wrapper" environments, like Matlab and Arduino, but raw C++ isn't a strong point. I've got access to all the CAD stuff that would ever be needed, Pro/E, Solidworks, AutoCAD, ANSYS, Strand7. I've got some skills in and access to composite manufacturing, like carbon fibre and glass but no vacuum baggin facilities anymore. My first project idea is a bargraph type watch - kind of like the awesome binary watches here, but the time increments on a bargraph. I think only one bargraph to show the minutes would be necessary - you pretty much know the hour most of the time, and you could work it out using the minutes if it's around the hour. A ten segment display would give resolution of 6 minutes - good enough for most purposes. I could do the hardware layout and manufacturing for this project, but I don't think I could do the programming. how about a homemade SMS device? not the most practical when mobile phones are so small and cheap and would be WAY more fully featured, but I think it would be cool to have a homemade device that could at least send SMSs. Open source, single sided PCB, would be awesome. obviosuly as small as possible but maybe aim for something the size of a blackberry of treo? Not stylish maybe but maximum hacker cred thumb keyboard ---> microcontroller ---> cellular module&LCD GPS based car locator - I know this functionality exists in modern cars but certainly not my 1994 feroza - a box that sits in your car that SMSs you GPS coordinates if your car alarm is activated. I've been looking for this for ages in a commercial product but the prices are outrageous. Other more outlandish projects are a CNC machine and single sided, through-hole, no (or very little) programming MP3 player Any ideas?
