3D, the way it should be®

Design the way you think

IronCAD lets you design the way you think, intuitively and powerfully. Drag & drop shapes, parts and assemblies from infinitely customisable catalogues, push & pull to make precise changes in seconds, and create assemblies in one file. It's a fundamentally better way to design in 3D.

It’s faster, easier to learn, and more flexible than traditional CAD software.

The speed to invent the future,
with time left to watch it unfold.

IronCAD models fast, and we mean really fast. Get ahead of your competitors and get to market faster with tools that skip many of the boring steps in traditional 3D CAD. Put simply, get far more return on investment for every minute you spend using CAD software.

'I have used pretty much all of the popular and expensive CAD systems, such as ProE, SolidWorks, Solid Edge, Catia, Delcam products, etc, but none were as easy, or as fast as IronCAD is. More things just get done in less time, period!' Mike Walls – Microplanet

In traditional CAD software, you usually start a model by creating or selecting a plane, then creating a sketch on that plane, and then creating a 3D shape from that sketch (like an extrude, spin, sweep, loft etc).

In IronCAD you skip these steps. They are still available for you if you want them, but you don't need them. For example, simply drag and drop a shape into place, it now has a sketch plane and cross-section already drawn for you, you can edit them at any stage, but you skipped the boring (and unnecessary) process of individually creating them.

But let's dig deeper. In traditional CAD software, you create all your parts individually and then assemble them at the end with mates and constraints. This is time-consuming and largely unnecessary, but also not the way we naturally think about products. We think about products as a related whole assembly, not as a combination of individual unrelated parts. It also means things don't always fit the first time around.

In IronCAD you design in the context of your assembly, whether your product is 10 parts or 10,000 parts, it can all be done in one IronCAD file. You get to design in the context of your whole assembly, seeing how parts relate to each other and sizing them to fit other parts in the assembly. Everything fits perfectly first time around. Another benefit of this is that you don't need mates or constraints for most parts because the only parts that need to be constrained are ones that have specified movement (like a wheel or lever). For everything else, you can completely skip the mates and constraints, which is a huge time saving compared to traditional methods.

This means, as a company, you can get far more done in the same amount of time. Maybe you were currently getting 4 drawings done per day, make it 8. Maybe you think you need another CAD user to keep up with demand, get them using IronCAD and they'll do the job of two people using traditional software. All in all, giving you more profit for every minute your company uses CAD software.

Learn in days, not months.
It’s made to think the way you do.

IronCAD is made to think the way you do. Our tools are not only powerful but built to be extremely intuitive. Many people can be comfortably using IronCAD in hours or days, not weeks or months like most CAD software. Whether you’ve got a busy schedule or want to train your team in a flash, we’d be very surpised if they can learn anything as fast as IronCAD.

'We use about 20 seats of IronCAD. You can design in 3D way way faster than normal programs, and it's so easy that even a 15 year old boy learns it within 2 days… ' Johannes Schreiber – Robotunits

Traditional software is often built around old-fashioned CAD drawing principles. This makes it much harder to teach a new person how to use it. Traditional programs often have multiple week-long courses and take months to get confident using, IronCAD is different.

IronCAD is built to be intuitive, that's why we have drag and drop catalogs, push and pull shapes and more. It's built to think the way you do, and give you predictable results when you want to get something done. IronCAD's methodology is logical, making it easy for new CAD users to pick up and understand quickly.

If you're learning it for yourself, this means you can get confident much faster than traditional software, and not have to worry about lengthy and expensive training courses. If you're training employees, this means you can have them working productively in far less time.

Make design changes when you want to. Not when your CAD software decides to let you.

Make design changes in seconds, without worrying about how the model was made or if you'll break the history-tree. The amount of time and money spent making late design changes is simply crazy, IronCAD changes that. IronCAD lets you model with or without history-dependency, so making a change to your model is as simple as doing it.

'IronCAD makes the design process quick and easy, by allowing users the freedom to work with precision, but without the necessity of constraints. Tools such as the TriBall and SmartAssembly, allow us to design quickly – and just as quickly, respond to the changing needs of our clients.' Michael J. Allen – Skyline Exhibits

Traditional software is history-dependant, this means that almost everything you do is dependant on the things and features that came before it. So if you delete or change one of those features, you can very easily 'break' your model, which can take a long time to fix. Users of traditional software will know this experience well, and sometimes have taught themselves ways to try and avoid these problems at all costs. We've heard many names for this over the years, a few being 'Tree of blood' 'Tree of death' 'Model explosion'.

IronCAD works differently, you can choose when, where, and if you want to have history dependency. This means you can just grab a feature or part and delete it, and everything will be fine, we really mean it. You can even move features up and down the tree. You still have feature history, it's just not history dependent. You get the good without the bad. Then if (in a very rare case) you want history-dependency, you can even turn it on. But trust us, once you've experienced the IronCAD way, you won't want to go back.

In addition to this, IronCAD provides a range of direct editing tools that even work for imported data from other systems. You can directly edit faces to make large changes to a model, and of course still use our shapes catalog.

This means, as a company, you can be ready for anything. A customer makes a last minute design change, no problem, just make the change and you're done. No more fiddling around trying to do things the way the software wants you to, do it your way and get more done.

Of Course, There’s So Much More.

The three big reasons above trickle down into an ocean of individual reasons to use IronCAD. For those who want to make their CAD process as efficient as possible, IronCAD is a goldmine for improved productivity.

Catalog System

IronCAD’s drag and drop catalog system is your 3D palette for useful CAD data. Whether it’s useful parts, features, tools, materials, animations and more, you can drag and drop them in to save them and out to use them at any time. It’s lightning quick and ncredibely customisable.

No Need For Mating

Because you can design everything in one file, all your components are already in the right place fitting perfectly. There’s no need to mate components unless you’d like them to have movement, in which case just mate the ones with movement and leave the rest.

Work With DWGs & DXFs

 IronCAD has two built-in drafting packages, one for drawing views in paper space and one for more advanced drafting, similar to AutoCAD. You can work natively with DWGs and DXFs and everything links back to 3D, updating instantly so you never have to redraw something again.

Dual Kernels (PARASOLID & ACIS)

Providing better import/export capabilities with collaborators, and providing a back-up kernel to solve complex geometry.

Optional Constraints

Choose when and where to apply constraints. In IronCAD there’s no “need” to apply constraints ever, you get to choose when they’re useful for you and when they’re not, dramatically reducing design time and letting you make design changes when and where you want.

Direct Editing Tools

Multiple powerful direct editing tools so you can easily edit imported “dumb solid” CAD models, and even use shape catalogs on them.

Turn Off History Dependency

There’s no need to worry about deleting a feature that is above other features in the tree, and you have freedom to re-use CAD data at will without worrying how it was originally made.

SmartAssembly Technology

Our SmartAssembly technology lets you set “magnetic” snap points so modular components automatically position themselves when dragged from a catalog. This can be used by sales-people on site to provide instant custom CAD models with associated manufacturing details and pricing.

Drag & Drop Sheet Metal

A whole catalog of drag & drop sheet metal tools so you can design quickly and intuitively. Then unfold your part and get bend dimensions and a flat pattern ready to be sent for production.

Get A Better View Of Your Design

IronCAD lets you stay in 3D longer, giving you a better overall perspective on your design. There’s far less need to go into 2D sketches, which keeps you designing and working in 3D. You still have the option to go into a 2D sketch whenever you like, but staying in 3D helps you keep your mind on the design.

Patented TriBall

The Triball is one of the most powerful and useful CAD tools in the world. Move, copy, pattern, and link features, parts, and assemblies all in 3D with a few clicks.

Integrated FEA & CFD Tools

Analyse your design from inside the IronCAD interface, then make design iterations and reanalyze them in seconds. IronCAD has free integrated FEA & CFD tools which can also be upgraded to more advanced versions when needed.

A few features we think you’ll love…

Perfect fit first time

There’s no need to mate or constrain every part, they’re designed together, so they already fit together perfectly first time. When you have a moving part, simply apply the constraint to that part of the model, skipping all the other constraints necessary in traditional 3D CAD.

Better behaved

IronCAD allows more intelligence and even domain-specific knowledge to be added to your components through a process we call Smart eBEHAVIOR. You can create intelligent features, parts or components that position, size and orient precisely onto other components. You can even add behaviours such as predefined constraints that can provide accurate movements in mechanisms. Further extend your design process by adding connections to other business related processes such as ERP to provide information such as pricing, availability, or manufacturing delivery to make more informed design decisions on your new products. Store this intelligence into your catalogues as Smart eCONTENT to share across your organization and even with customers using any one of the IronCAD products to meet different users’ levels of expertise.

Why would I choose IronCAD over Inventor or Solidworks?

An excellent question and one that we, as CAD International deliberated over for a long time before selecting IronCAD as our preferred MCAD software to sell and support.

When we did our assessment of the leading MCAD software we looked at Pro-E (Pro Engineer), Solid Works, Solid Edge, Inventor, Alibre Design, Think-3D, Solid Thinking and Space Claim.

All the CAD software in this segment of the market have strengths and weaknesses, but we discovered with IronCAD that it was quite unique in how it modeled, making it faster to learn, faster to use and significantly easier to make changes to a model at any stage in the design process without lacking in any area that we could reasonably test.

In simple terms whilst each of the others had their individual redeeming features, IronCAD could do everything they did as well as having some totally unique tools of its own.

IronCAD’s popularity is growing rapidly in most regions such as South East Asia, Australia, New Zealand, Europe, UK and Japan. Since CAD International have embraced the software buyers have been further reassured due to the company’s reputation for excellence in support and its logevity in the industry.

Is it important to model things in strict order?

Not in IronCAD. The other products only use a structured history-based approach – This means the order in which you model your design is critical to the way your model behaves as you make changes – get the order of features in your model wrong and one simple change to one small aspect of your design could mean the most bizarre results and time consuming re-building to make the model work again.

IronCAD is different because it has both structured and non-structured part design. Non-structured works particularly well when you are in the more creative stage of design and are testing out concepts and ideas and need to make radical changes quickly without being constrained by the model’s sequence of construction.

Amazing at it may seem, IronCAD is unique in its ability to simply drag pre-ordaned features from a palette onto your model. This makes it faster to apply features than in any other product. This same drag and drop approach also applies to assemblies and even materials for rendering. The single design environment also means you can work seemlessly in the assembly and in the part at the same time.

The patented TriBall feature alone is a big reason to work with IronCAD. It is the most intelligent method of modifying the geometry of your design. Others have tried to copy but have done a poor emulation – It remains the industry leader in model manipulation. It can take a little while to master it but when you do there’s no turning back.

How does it handle large assemblies?

Full question was..”We have large assemblies with thousands of parts. Our current CAD software does not cope very well with these, especially when generating 2D drawing views from the model onto the page. It has a feature designed to make the parts in the assembly less demanding but it doesn’t seem to help much. How good is IronCAD with large assemblies?”

IronCAD’s earlier versions had much the same problem that you are experiencing but the two latest versions are brilliant at handling large assemblies. There are special modes of display for small parts and also a way to generate 2D drawings without having to compute every aspect of every part of every assembly of every sub-assy of…you get the picture. Its good.

Additionally, models that are detailed and contain many components will render on screen in real-time faster than any other software we tested which makes working on large models much easier. It is still important to run a fast CPU with lots of RAM and preferably Windows 10 on a 64bit machine.

Do you have a list of users of IronCAD in Australia/NZ?

Full question… “We are an Australian manufacturer and have heard good things about IronCAD. We currenly use AutoDesk Inventor but we are not really happy with it. Could you give me a list of users of IronCAD in Australia that I might be able to talk to? From what I have read on the net and in forums IronCAD looks like it might be a much better fit for us but it helps if we can talk with users first hand.”

Here is a list of some clients currently using IronCAD in your region that are ok for someone to chat with them. You will find several have been using other programs like Inventor and Solid Edge or Solid Works but have made the switch to IronCAD. I don’t recall anyone going the other way!

Can I install IronCAD onto more than one machine?

Yes. there are several options. You can load IronCAD software onto as many machines as you like and simply unregister and reregister your license in a simple online procedure to move the license from one machine to another. Alternatively you can purchase an optional USB license dongle that enables the software license on whichever machine the USB dongle is plugged into. Finally, if you need access to IronCAD from multiple machines at the same time on your network you can purchase a network license manager that will allow you to run as many licenses as you have purchased at the same time on any machine on the network.

How does IronCAD rate against Alibre etc?

Full question…”How does IronCAD actually rate with software like Solid Edge, Solid Works or Inventor etc? I am currently using Alibre and find it very limited. I have used SolidWorks and quite liked it at the time. IronCAD ‘looks’ like it would be best but I am not really sure?”

I think the best way to answer is to explain where most MCAD products fit in relation to each other.

At the bottom of the pile are products that lack key functionality or have simply added ‘solids modeling’ to an existing ‘wire frame’ CAD environment to allow them to say they have ‘solids’ – These include AutoCAD, TurboCAD, Bricscad and many others. They are literally older tecnologies with solids bolted on.

Next are the ‘entry level’ parametric solids modelers. These are true modelers but are typically limited in functionality or fail when certain complex designs are attemped. They often do not support good file exchange or large assemblies but are fine for smaller one-off designs. Alibre and several others fall into this category. they are usually priced at around $3000 or below.

Following up the ladder from these are the far more professional modelers. These include Inventor, SolidEdge, SolidWorks and IronCAD (in that order). Typically these are sold well above $4000 per license with an additional upgrade or support cost on an annual basis. They are comprehensive and powerful products, each with their own strengths and weaknesses.

We place IronCAD at the top of this group because IronCAD has the abilities of the other products but a design approach that is far more flexible and therefore faster and easier to use or make changes to a design. IronCAD’s drag and drop feature, it file structure and the way geometry is manipulated is definitley superior. As a simple example of this, there is no need to sketch a profile and extrude it every time you want a part or feature – you simply drop a pre-shaped part or feature into the scene and push, pull and attach it how you need.

From our observation IronCAD has historically been more innovative with important features – these features are often then emulated by the other players in the market several years later.

Sitting above these so called mid-range MCAD solutions are products like Catia, Unigraphics, and Pro-Engineer. These top-of-the-pile mega CAD products are sold at a much higher price and cost far more to maintain. They often have far more advanced surfacing abilities and engineering FEA built-in. They are used by companies involved in projects like major aircraft design or massive engineering projects. Each year we find that the more advanced features and functionality of these top-end programs are being incorporated into the mid-range software.

The best way to be really clear about whether IronCAD is right for you though, is to ask one of the CAD International engineers. Be sure to tell them exactly the sort of things you will be designing so they can advise you correctly. If IronCAD is not the best solution they will tell you!. They don’t want you to come and complain to them after you have made your purchase! There are a lot of factors to consider when buying so take the advice of the experts to avoid making a costly mistake.

Is there a CAM option?

Yes, there is a very comprehensive CAM software to operate directly within IronCAD although most users with CNC needs simply use the CAM software that is recommended by their machine supplier. IronCAD works with all reputable CAM software.

Why do I need dual kernel technology?

This video visually explains why it is important to have both ACIS and Parasolid modeling engines.
