content: Hi, I'm building a tube amp and need to design a case for it (you know, mark where to drill holes for the sockets, transformers etc). Last time I needed this (tube headphone amp), I only needed to do the top of the case, so I just marked what I needed using a PCB design program. However, this time I am going to drill at least three sides, so it would be helpful to be able to visualize it in 3D (so I do not put audio input right under the power transformer). And then I should be able to print the markings so that I can mark the holes on aluminium and then drill them.What software (preferably free) do you use for this? It should run on Windows 7.

content: hm There are a few programs out there but as far as i know not hugely functional. I think google have a software but I can't remember the name.At work I use Solid Edge but that is costly and well I don't have many polite words for it when I'm working on it.

content: I use Turbocad for 3d and 2d, but only use the 3d stuff to prove designs before sending them off to get cut.Unless you want to get into the high end of 3d design, just use whatever - all pretty much the same.IMO the way 2d files are produced from the 3d renderings is far more important. Most cutting places will charge you a massive premiumfor crappy 2d files, if you're not sending any files off, doesn't really matter.So in my opinion i'd go for a autocad / turbocad level software for this sort of stuff. Just download a student edition (wink wink)as you'll might as well learn something that has some real world manufacturing benefit (small time stuff)I've never used any high end 3d (solid works / rhino ect) but mention files produced by these software packages to a laser cutter and you'll cop an ear full of nasty.

content: I just foundDRAFTSIGHTa few days ago. It looks promising and has a free version but I haven't had a chance to try it. I have used AutoCAD back in the DOS days and prefer it. But it costs far too much for hobby use. I bought TurboCAD and it's okay but terrible hard to learn and print drawings at full scale to use as templates.

content: I use Alibre Design, now called Geomagic Design. It's ok, but a bit buggy (and not free).I always create 3D objects of my boards, enclosures, and parts to get the fit right (75% right the first time and improving.There is a new free online CAD software,https://www.onshape.com, which is pretty good (although it came up on page 7 when I googled "Free online cad"). It looks very similar to most parametric cad programs.

content: I personally use Rhino. It's not great for actual assemblies, but it's very easy to build the solid models for various parts. Since it doesn't have constraints, when it comes time to assemble things, you need to put on your big boy pants and start doing things like changing the construction plane to appropriate surfaces, and really learning how to use some of the more advanced features. But if you can do that, it's not a bad program for this kind of thing.I keep looking for something else...haven't found it yet. Rhino is best overall for me right now. That will change when I need to start doing sheet metal. I tried Geomagic (formerly Alibre). Honestly, I wasn't particularly impressed. I want something where I can model my parts (or parts of parts) in Rhino, and then suck them into a parametric modeller with constraints to actually assemble the parts into something that I can work with.I'm really spoiled with Rhino's interface. Everyone should follow their example of what a clean, powerful interface is like. I'm terrified that they will completely screw it up in the next version in order to comply with Microsoft's garbage UI initiatives.

content: I have not made the jump to 3d cad tools. a friend is a wiz at solidworks but its intimidating to new users.I mostly use laser cutters and those are 2d tools. I can get most of what I want done in 2d by using layers or building 'tab boxes' (http://boxmaker.connectionlab.org/).for the tool, I use corel draw since its the tool that my hackerspace (techshop) uses to drive the lasers. its easy to use, its not buggy and it does quite a lot. its also not overly expensive.on the linux side, I'd use inkscape. its free and very capable as well, with quite a few nice plugins (including a box maker, as well). inkscape runs fine on windows, too!

I remember seeing this a while back but lost the link.I have just ordered a few panels for some portable VHF boxes (in Pelican cases with batteries and accessory outlets). Will post the results when they arrive. Extremely quick and easy to lay out. Prices were comparable with our local sheet metal fabricator - but they're not cheap for small quantities either.

Extremely well made for new users and experts, up to level of cerrtification.

content: Solidworks is ideal but it costs money. Sketchup is excellent for a beginner and has a massive following on youtube, that would be my recommendation. A good basic starter.You may want to look for 3d printer software. Anything that can design 3d objects can do the job that includes 3d software designed for the movie industry. It's not unheard of (in fact common) to use a particular function to manipulate an object and the export it back into your favorite.
