Free CAD software shouldn’t have to break the bank.

1. Free Invention Design Software
2. Free Invention Design Software Programs
3. Free Invention Design Software Download

There are thousands of kinds of free CAD software available. Possibly tens of thousands. But there are far fewer free programs in the CAD realm—if only because CAD software is incredibly difficult to create.

The term comparison between objects created manually and those designed using Product Design Software differ, with the former taking so much time, hence rendered inefficient, slow, boring, and intimidating.You can also see this Graphic Design Software. The invention of Product Design Software led to an increase in the productivity of product.

• AutoCAD Inventor Fusion Not many companies give away really competent solid modeling free CAD software. Autodesk won’t be giving away Inventor Fusion forever, but for at least until next April, you can download a copy from Autodesk Labs, and enjoy using without going out of pocket even a single cent. Inventor Fusion is a “technology preview.”.
• Invention free download - Vector Clocks, Invention Calculator, Invention 2, and many more programs.
• Autodesk CFD Design Study Environment and CFD Motion: Autodesk® CFD Design Study Environment software has been discontinued and commercial versions are no longer for sale.If you have downloaded a previous version of CFD Design Study Environment and/or CFD Motion software, you can continue to run that version; however, you will not be able to download a newer version.
• Autodesk® Inventor® software provides engineers and designers a professional grade solution for 3D mechanical design, simulation, visualization, and documentation. Autodesk Inventor includes powerful modeling tools as well as multi-CAD translation capabilities and industry standard DWG™ drawings.

Here are three free CAD software programs that offer something really special. They’re each from major software developers who sell commercial grade 3D MCAD software. These vendors, of course, hope that you’ll love the software they’re giving away, and will buy their commercial software—but they’re not playing the “let’s give away useless software” game. This free CAD software is good stuff. If you try it, you’re going to like it.

IronCAD COMPOSE
IronCAD COMPOSE is one of those programs that takes too much work to describe. Heres’s how it works: You open up a blank scene file in IronCAD COMPOSE, and then drag and drop models and assemblies from other CAD systems into that scene. You then move those models and assemblies as you like, until you get an arrangement you like. And, if you want, add animation.

IronCAD COMPOSE lets you build up assemblies by dragging and dropping individual parts from catalog files. These assemblies can be animated, rendered or exported to 3D PDF format.

That’s the simplistic explanation of how IronCAD COMPOSE works. The important question is this: What can you use it for?

Quite a variety of things, it turns out. You can use it to create assembly instructions and animations for your factory. Your sales people can use it to create customer presentations of configure-to-order products. You can lay out your office, or your assembly line, or most any other space you’d like, in full 3D. And other people in your organization can use the IronCAD viewer to explore those compositions. Or, if you prefer, you can save your compositions as animation files, rendered images, or 3D PDFs, and put them up on your website.

IronCAD COMPOSE is also free. You can download it from IronCAD’s website, and you don’t need to pay anything.

IronCAD COMPOSE is essentially a CAD program for creating assemblies of assemblies. It has all of the parts creation tools removed. It works with existing parts and assemblies, and lets you compose what are essentially digital mock-ups. Out of the box (so to speak), it can read a variety of faceted 3D formats, including STL, VRML, 3D Studio, AutoCAD 3D DXF, TrueSpace, and Wavefront (OBJ). No matter which CAD systems you’re using, you should be able to create one or more of these formats. If you prefer to work with live CAD files (as I do), for $195 IronCAD will sell you a translator (COMPOSE Trans) that’ll read native files from ACIS, PARASOLID, IGES, STEP, CATIA, Pro-E, Unigraphics, SolidWorks, and Inventor. That’s the only “catch” to IronCAD COMPOSE’s free price.

Once files are imported into IronCAD COMPOSE, you can add attachment points on them (to allow smart snapping between parts), and, if you like, save them in a catalog, for later reuse. COMPOSE includes several sample catalogs of parts, finishes and textures. The program is entirely drag-and-drop, push-pull. To lay out a conveyor, for example, you just open the conveyor catalog, and start dropping parts and sub-assemblies into the scene. When you drop one part onto another part, they automatically snap together in the proper orientation, based on their attachment points.

A good example of a company that uses IronCAD catalogs is Skyline Displays, a well known supplier of trade show exhibit furniture. Skyline has taken the CAD models of its products, and saved them as IronCAD catalogs. Using IronCAD COMPOSE and those catalogs, almost anyone could snap-together a custom Skyline trade show booth in no time flat.

Skyline has been using IronCAD, and creating catalogs with it, since about 2004. But, they haven’t actually been using IronCAD COMPOSE. First, because COMPOSE only came out in May of this year, and second, because IronCAD wouldn’t be nuts enough to put everything Skyline needed (for example, a quotation system and an interface to ERP) into a program that they were giving away for free.

IronCAD did, however, put enough capabilities into COMPOSE that it’s a useful and flexible tool for a lot of ancillary jobs that typical CAD systems aren’t really appropriate for.

As you might imagine, IronCAD is hoping that a lot of people will use COMPOSE for interesting projects, and will start liking its drag-and-drop method of operation. If that happens, a certain number of people are going to take a look at IronCAD, and realize that it’s a pretty interesting tool—even working along side other CAD systems.

AutoCAD Inventor Fusion
Not many companies give away really competent solid modeling free CAD software. Autodesk won’t be giving away Inventor Fusion forever, but for at least until next April, you can download a copy from Autodesk Labs, and enjoy using without going out of pocket even a single cent.

Inventor Fusion is a “technology preview.” It’s Autodesk’s attempt to grab not just the attention of their existing users, but those of their competitors as well. Inventor Fusion is what is generally called a direct modeling CAD program. It doesn’t require the use of history-based parametric features. Rather, it lets you edit most any 3D CAD files—solid or surface—without the need to understand how they were built, or even what CAD system created it. Inventor Fusion supports reading an exceptionally wide array of 3D CAD formats, including those from most of the major players, including CATIA V5, NX, Pro/E, SolidWorks, Alias, Parasolid, ACIS, STEP, IGES, and even Rhino. About the only important 3D CAD formats it’s missing are JT and 3D PDF.

Autodesk Inventor Fusion supports direct editing of both solid and surface models. Someday it will cost money. For now, it’s free.

While Inventor Fusion is designed to work in conjunction with Autodesk Inventor (the non-fusion version), it stands on its own merits, in three particular areas.

First, Inventor Fusion has a well-refined interface. It doesn’t spread your attention all over the screen. Rather, it keeps the information you need near where you’re working. Its selection tools are nicely done, and its sketching and modeling tools are context aware. Overall, it’s a far nicer user interface than most CAD users would expect.

Second, Inventor Fusion has capable tools for modeling and editing both solid and surface models. While, in my experience working with Inventor Fusion, I found some files that I was unable to edit as I wished, my sense was it was more a matter of my lack of experience than Inventor Fusion’s limitation.

And, third, Inventor Fusion includes a couple of tools that make it really interesting for preparing models for CAE. It has a model simplification wizard, to remove small features, and has a wizard to create fluid volumes from assemblies, for CFD. There’s quite a bit of interest among CAE people in using direct modeling CAD systems for model preparation. Autodesk has bought several CAE companies over the last several years, so it makes sense that they would include these tools in Inventor Fusion.

When Autodesk gets around to charging for Inventor Fusion, they may include more with the software, or, more likely, bundle it with some of their other products. For now, as a standalone product (and one that’s free as well), it has a prominent place in my collection of tools.

Solid Edge 2D Drafting
Some day in the future, it will be common for engineers and designers to create 3D models, and annotate them with 3D GD&T. And never create drawings. But for now, we all love our drawings.

The good 3D MCAD systems all support the semi-automatic creation of drawing views from 3D models, as well as model-to-drawing associativity of dimensions. But there are times when you need to create just a drawing. Without an associated model.

Sometimes it doesn’t make sense to create a 3D model when a 2D drawing will do the job. Solid Edge drawing of a worm shaft, courtesy Thorsten Hartmann.

The most common 2D CAD software is AutoCAD. In its various incarnations, it’s the most popular CAD software in the world. It is certainly good general purpose CAD software, but it’s never been the best mechanical drafting software you could get. For really good 2D drafting software, you need to look for a CAD product with a heritage that can be traced back to the days of the Apollo space program, when Huntsville, Alabama was the epicenter of rocket research in the United States. That product is called Solid Edge. It was conceived and created in Huntsville, and to this day is still developed there.

As good as Solid Edge 2D drafting is, its price is even better. It’s completely free. Siemens PLM Software is keenly interested in selling 3D CAD software, not 2D CAD software. So they just give the 2D software away. They’re rather have you using their 2D software for free than paying their competitor to use their 2D software.

It probably wouldn’t matter If Solid Edge 2D drafting were junk. But it’s far from it. It does all the things you’d want in a really good 2D drafting program: It supports parametric drawing layout, complies with an alphabet soup of international drafting standards, including ISO, ANSI, BSI, DIN, JIS and UNI, and is compatible with the ubiquitous DWG format, used by AutoCAD and most other 2D CAD programs. But it has a few bonuses too.

One nice bonus is support for drag-and-drop diagramming for elecrical schematics and P&ID diagrams. Another is Goal Seek, a function that combines free-body diagrams with a 2D parametric sketch solver. Goal Seek is one of the best kept secrets in Solid Edge 2D Drafting. It’s a true design engineering tool, and its results can be used to drive parameters in your 3D CAD system.

We’ll talk here about the best inventor software on offer for use in different steps of the invention process.

Brainstorming Inventor Software

bubbl.us

bubbl.us is a free and very easy to use online mindmapping service. Within minutes you can have a nice looking and multi-leveled mindmap. You can also save, print, import and export your mindmaps for modification or future reference.

Microsoft Visio

We’ll speak about Microsoft Visio in more detail in the Patenting Software section below. Besides 2D design work, Visio can be used for mindmapping and brainstorming, and thus is great for the creation and ideas phase of the invention process. It allows you to build keyword hierarchies in an easy to use and organized manner, and moreover lets you order them and re-organize them if necessary. The advantage of using Visio as opposed to, say, just sketching a mindmap, is that you can always come back to your brainstorm and modify or re-engineer it at a later stage.

SmartDraw

SmartDraw is an excellent piece of software which we’ll talk more about below, and it works in similar fashion to Visio for brainstorming purposes. Check out some SmartDraw brainstorming examples to see how easy it is to brainstorm and mind-map with it.

Inventor Software For Sketching

In this section we’re going to look specifically at tablet apps. Tablets such as the iPad have become incredible tools for inventors, as they allow you to sketch ideas on the go using powerful sketching software.

Sketchbook Pro

Sketchbook Pro is one of the best iPad and Android apps out there for invention and idea sketching. It provides multiple types of digital pencils, brushes, markers so that you can freely sketch your ideas and innovations in a way that works for your needs.

Check out this video to give you a good overview of how Sketchbook Pro works:

Paper by FiftyThree

Paper is another amazing sketching app that focuses on simplicity and a provides a minimalist design interface. It allows you to organize your sketches into digital ‘books’ in a very cool and effective way. Use it if you like to make lots of quick sketches: it beats a physical sketchpad any day.

Invention Product Design Software

Google Sketchup

Google Sketchup is a simple yet powerful piece of 3D modeling inventor software, and the free version is a brilliant way for inventors to start modeling their designs into 3D objects. Some of its features include conversion of 2D designs into 3D, exact measurements for prototyping and production purposes, grouping and ‘clipping together’ of distinctly designed components, texture and color surfacing, animations and presentations of designs and even a feature to cut away and go inside a design.

Google Sketchup comes with lots of free training videos (as well as real-world training), and here’s an example of one to see how it works:

AutoDesk Inventor

Free Invention Design Software

Inventor software AutoDesk Inventor is a state-of-the-art 3D CAD design system that allows you to design, control and even simulate your inventions before building produce physical prototypes (sometimes even preventing the need to product a physical prototype). Its numerous features include converting 2D CADs into 3D, assembly design, motion simulation and mold design. It also comes with video tutorials that guide you through all features of the inventor software package.

AutoDesk Inventor software comes in different versions and different prices, and it’s one disadvantage is that it’s quite pricey (from $999 onwards). However if you use it to its full capabilities, and put in the time to learn how to use all its features, it’s worth the price. Take advantage of the free trial if you want to test it out.

Here’s a very long but very comprehensive demonstration of using the invention software to design an LED Lamp:

Patent Design Software

Microsoft Visio

If you have a PC with Windows installed, one of the best patenting design software you can get is Microsoft Visio (available in both standard and professional versions). Visio is a very powerful design tool, which is primarily used for 2D design work. As a result it allows you to draw up virtually anything that would be required for 2D patent document diagrams. This includes patent diagrams, flowcharts and scenario charts. Visio allows anyone to build professional looking designs using existing templates and pre-drawn shapes. For the most part you can do these designs without requiring the services of a professional draughtsman.

If you are wanting to get to grips with patent designing, particularly when using a design tool like Visio, it always helps to do a patent search.

Here’s a Visio demonstration video:

SmartDraw

SmartDraw is the non-Microsoft equivalent of Visio, and some people prefer it because it is an independent company and regularly updates its software (Visio has much longer product cycles). It can do virtually everything that Visio can do in terms of 2D design work, and includes hundreds of templates and pre-designed shapes. In other words its a great piece of inventor software, and allows you to come up with professional looking designs without having to be a professional designer.
