BricsCAD Shape for Mac

BricsCAD Shape, the free DWG-based 3D direct modeling application from Bricsys, has now been released for macOS (formerly OS X). See my previous post on Shape for details of what it’s all about.

This is the same, just on a different OS. That’s because unlike Autodesk’s versions of its DWG products, the Bricsys versions are not cynically watered down for Apple users. Those users can now do full 3D conceptual modeling as part of a workflow that leads to full BIM (or simply view and edit DWG files if you’re not that ambitious), and without paying for the privilege.

It’s a proper free perpetual licence without usage restrictions, not a demo. You can’t get a perpetual license of DWG-editing software from Autodesk for any money, so by any measure Shape is a bargain.

The Bricsys blog post can be found here. The download page is here.

A Linux version of Shape is expected later.

Bricsys shows Autodesk how to do mid-term updates – again!

BricsCAD V18.2 for Windows is out. The new stuff in this mid-term update is again showing up Autodesk’s lack of progress with its once-flagship product, AutoCAD. I’m sure Autodesk would love customers to accept that there’s only so much anyone can do with a DWG-based CAD product once it reaches a certain level of maturity. Customers should get used to nothing of significance being added year after year. Diminishing returns, and all that. Pay to continue using the product, but don’t expect it to get better.

What a shame for Autodesk, then, that Bricsys exists. By consistently providing a raft of significant improvements with each full and mid-term release, Bricsys shows up that idea as nonsense. It’s perfectly possible to keep improving CAD at a very rapid rate, particularly if you’re not worried about competing with other products in your range. There’s a reason AutoCAD’s parametrics are restricted to 2D, and BricsCAD’s 3D parametrics in a DWG product proves that the reason isn’t technical. It’s strategic. Also strategic is cutting the guts out of an already much-weakened AutoCAD team, because you would really prefer your customers to be using your trendier and/or more expensive products.

I should point out that BricsCAD V18 customers who have a perpetual license, even without maintenance, will be receiving V18.2 with all its improvements free of charge. Contrast that with Autodesk, which is, despicably, withholding even bug fixes from selected customers. Autodesk’s attitude to customers who aren’t constantly paying up front is one of utter contempt. Autodesk feels entitled to your money; Bricsys wants to earn it.

So what’s Bricsys done to earn your money with BricsCAD V18.2?

Mostly, it’s lots of relatively small-sounding things that add up to significant productivity enhancements. There are several items that are playing catch-up to AutoCAD, such as long-overdue in-place text editing. There are big performance improvements in drawings with PDF underlays due to a smart multi-resolution cache mechanism. The 3D-to-2D generation mechanism has also been significantly sped up. Constraints (2D and 3D, unlike AutoCAD) are easier to create. Several 3D direct modeling operations have been made easier. That also helps with sheet metal design, which has seen other improvements.

In Bricsys BIM V18.2, a lot of smarts have been added. The mechanism for converting CAD models (including those made in BricsCAD Shape) to BIM models, BIMIFY, already did some fascinatingly clever things, but that’s been improved further particularly in the areas of structural member and room recognition. For those of us in Australia, support for our steel sections is very welcome.

For me, that’s not the big news. Oh, no. The big news for me is a thing called BLADE – the BricsCAD LISP Advanced Development Environment.

If you’re a CAD Manager or in-house developer and you’ve been waiting until BricsCAD had VLIDE, wait no longer. But this isn’t just catch-up. This is a big leapfrog over Autodesk’s sadly neglected IDE for CAD’s primary user programming language. There’s so much good stuff in BLADE that I can’t hope to do it justice here, so I will be covering it extensively in future posts. For now, here’s a statement for you:

If you program in AutoLISP or Visual LISP, you should be doing it in BLADE.

It’s that good. Really. Watch this space for details.

The download is small, the install is fast, it won’t harm your AutoCAD installation, and you can evaluate it free for 30 days. Links:

That awkward moment when I just failed to create BIM

I recently updated my resume, and I thought it might be relevant to include an episode from my early career. This post is an expansion on what I had to say about that episode.

I was managing a tiny CAD training and development company, Educad. Much of my time there was spent developing software called NIDIS (originally called NEEDS), a project that was started in 1987 or 1988 with Nixdorf Computer as the client. It was intended to take over the market among first the home building companies of Western Australia, then Australia, then the World!

What’s special about NIDIS is that it was a precursor to BIM. Using a 3D-adapted version of the 2D Educad architectural software within AutoCAD, designs of domestic homes could be efficiently created and infused with a degree of intelligence. This was then linked to the Nixdorf minicomputer-based software that contained pricing and other information about the various building components. This combined system enabled accurate quantity take-offs to be performed.

This was supposed to be a short project, but due to a massive amount of “scope creep” it took two years. I was really pushing the limits of what AutoCAD could be persuaded to do at that time and had to break new ground in several areas. Some of it was a kludge, but I made it work. Finally, the software was essentially completed, with a custom tablet menu (remember those?), full documentation and everything. Nixdorf CAD-spec PCs with big screens, tablets, AutoCAD and NIDIS were installed in the drawing office. It was successfully tested in Beta. The take-offs were very accurate. Everything looked good to go.

Then, two weeks before it was due to go into production, this project died. The building company that was sponsoring it, Mansard Homes, went into liquidation as it struggled unsuccessfully with the combined effects of very high interest rates and bad publicity about poor building quality and cost overruns. Nixdorf dropped the whole project like a hot potato and the product was never sold. I didn’t have any rights to the software and couldn’t do anything with it.

But it was software that was based around a 3D model of a building that contained some intelligent information, albeit extremely crude by today’s standards. I wrote, quite literally, Building Information Modeling software. It was completed in 1989, before the name BIM had even been used. The idea had existed since the mid 70s, but I didn’t know that at the time so I made it up as I went along.

I didn’t actually invent BIM, but I made something that resembled BIM that actually worked. And then it didn’t.

This is easily the most spectacular failure of my career. Still, I’m kind of proud of it.

Edit: for historical context, this video shows an unrelated system that was developed at about the same time as NIDIS.

BricsCAD Shape – can a free DWG product be a BIM game-changer?

At the Bricsys 2017 Conference in Paris, one of the biggest surprises was the announcement of BricsCAD Shape. This product was demonstrated live, very impressively, in pre-release form. As I live-tweeted at the time, the demo jock was able to create a pretty decent architectural model in minutes, from scratch, very easily. That product has now been released.

What is BricsCAD Shape?

Shape is a 3D direct modeling application. At the core, it’s a simplified BricsCAD BIM. That means it’s small, fast, stable and it uses 2018 DWG as its native format. These are all good things. It’s obviously aimed at the AEC market, but there’s nothing to stop anyone using it for anything. Use it as a lightweight DWG viewer/editor if you like.

As you can see, it has a very simple, clean, cut-down interface. That dude is French Architect Jean Nouvel, by the way. He’s a block; you can erase him. He doesn’t appear in DWG files from other sources you open in Shape.

The idea is to do most of your work with the 18 buttons in this mini-ribbon/monster toolbar thing:

For less common operations, there is a set of pull-down menus. Although it’s hidden by default, you can even turn on a command line (Shift+F2) that will be very familiar to AutoCAD and BricsCAD users. Try to do without it; you will then discover how the excellent Quad Cursor interface (inherited from BricsCAD) uses AI technology to save you time and clicks.

How do I get it?

Click this link, enter your email address (no, they won’t sell it to spammers), and download away. Unlike Autodesk downloads, there are no nasty Akamai download managers to contend with, no multi-stage install processes, no massively bloated files, just a straightforward download of a 212 MB MSI installer. Time to download for me on ADSL2 was 2m 56s. The install time, including user interactions was 36s. Time for the first startup, including online registration, was 15s. That got me to the startup screen. The time for the first drawing startup was another 10s.

You can be using Shape in under 4 minutes. That is, you could be using it yourself in less time than it takes to read what I have to say about it.

How is it licensed? How much is it?

It’s a perpetual license, and it’s free. Bricsys has stated that it will always be free. Not much to complain about there.

So what’s in it for Bricsys?

The problem Bricsys faces in churning over large numbers of Autodesk’s disgruntled customer base is not the products. The products are fine. BricsCAD is notably superior to AutoCAD in a bunch of significant ways (while remaining inferior in a handful of less important ways), and costs a fraction as much.

No, the problem Bricsys faces is in persuading large numbers of people to try its products. Shape is an attempt to make that happen. It’s an ice-breaker in a way that goes beyond the usual 30-day free trial product.

There’s hardly any bar to entry; anybody with an email address can own it with zero investment. The interface has been kept very simple and there are a whole bunch of bite-size tutorial videos that demonstrate how to do things. If this product can create a buzz and get people to use a Bricsys product, half the battle is won. The models it creates are ready to be easily taken to the next stage using the full, paid product, BricsCAD BIM.

It’s not SketchUp
There are superficial similarities between Shape and the discarded-by-Google product, Trimble SketchUp.

However, there are very significant differences. SketchUp Free is a cloud-based product that works inside your browser (the paid product is currently a desktop product). Shape is a standalone application that does not require the Internet. SketchUp has its own file formats; getting those models into CAD or BIM is fraught. Shape is not just using industry-standard DWG file format, it’s a proper, efficient, accurate CAD application. Because it’s a cut-down version of what Bricsys is hoping you will use to fully develop the models later, there is no translation. The model you build in Shape opens directly in BricsCAD BIM where automatic classification of building elements can take place.

BricsCAD Shape. It’s free, it’s easy, it’s DWG, it’s CAD, it’s 3D, and it’s a pathway to BIM. It could change the game. I have no way of predicting whether that will happen. But if it does, it’ll be another kick in the guts for a dormant Autodesk that has largely given up on improving its products.

The big Bricsys interview 9 – treading on developers

This is one of a series of posts covering an extensive interview with Bricsys CEO Erik De Keyser and COO Mark Van Den Bergh. Erik explains that Bricsys won’t trample over its application partners in Autodesk-like fashion, except…


Steve: Autodesk is known for treading on its third-party developers and replacing their market. Can you tell us about your attitude to doing that?

Erik: We have always said that we are not stepping into any application market. We will not do it.

There’s only one exception, that’s where there is no [other] possibility. There was no sheet metal. There is no viable [third-party] DWG sheet metal product in the market today for sheet metal. Then we do it, of course.

For BIM, there are. There is a German product. We have talked to those guys, but the problem is, for BIM the way we do it, it’s so deep in the core, the direct modeling engine that we have build… there’s no way that we could expect, of all the partners that are working on AEC, that one would have the strength and the force to bring the product where it is today. We have worked with maybe 30, 40 people for three, four years to do that. I don’t know of any application partner that has more than ten employees. And then those ten employees do everything.

Mark: Except for Intergraph, of course!

Erik: Except Intergraph! Except Intergraph! In the AEC space, I mean. When it comes to making an architectural modeler, there was no other possibility but to do it ourselves. Then we do it. But what we do then is provide all the APIs so the rest of the AEC community can profit off it. Otherwise, I think we would have lost the AEC space. If we didn’t do that, with what we have shown you today on BIM, we would lose the AEC space completely. That could not happen.

The big Bricsys interview 8 – boundaries and BIM

This is one of a series of posts covering an extensive interview with Bricsys CEO Erik De Keyser and COO Mark Van Den Bergh.

Erik discusses where Bricsys can go in future and the place BIM has in that.


Cyrena: So what is your vision, ultimately, of what Bricsys will become in tandem with your partners? Do you have limits or boundaries of which markets you will address and which you won’t? Are you going to be bigger than… “somebody else” one day?

Erik: If it comes to the number of customers, challenging AutoCAD is difficult. 12 million registered users. If you count illegal users it might add up to, I don’t know, 20 million, 30 million? I don’t know, nobody knows.

What are the boundaries of where we can go? It’s more or less dictated by the application markets. We have application developers in GIS, we have them in AEC, we have them in mechanical. In Mechanical 3D, AutoCAD was not present. They were present with AutoCAD Mechanical, but that’s a 2D product. If for a moment I leave Inventor out, because it’s another file format, but for DWG, the market for sheet metal and the things that Solidworks and others do, you don’t see third party applications with power participating in that market, with AutoCAD. With all the other markets, there are plenty of other applications: GIS, AEC, it’s endless. We want to bring everyone who wants to work with us, we’re going to feed and help them, and that’s more or less the boundary of where we can go.

For BIM, that’s something we are driving ourselves and it’s a huge market. There’s a lot of attention being paid to Revit [by elements of the press]. We think there are a lot of DWG users that want to move to BIM, but first of all Revit is too expensive, it’s too complicated by far, and it’s another file format. These are hurdles that not everybody wants to jump at the moment. It’s fair to say that we are working to eliminate all those hurdles. An existing DWG user, AutoCAD or BricsCAD already knows 80% of our BIM product. He has to learn 20% extra and he can participate, probably in an easier and more intuitive way than he can ever do with Revit.

We didn’t talk a lot about the differences between Revit and our BIM solution. I think in six months and a year we’re going to spend more time to really explain the differences. BIM is hyped, but there are studies that show that 19% of the people who talk about BIM are actually using it. It’s a couple of hundred thousands, it’s not millions already. There’s a lot of hype around it but the real challenge is to bring five or six million people on DWG in the AEC space into BIM. That’s our goal. If they want to stay on DWG, we are their only chance. For that part only, that’s already a huge start. If you then count all the applications on top of that and around it, the addressable market for us on that is immense.

Another one bites the dust – Autodesk sheds Seek

Following on from Autodesk’s announcement of the impending demise of 123D, the shedding of Cloudy applications and services continues. This time, it’s BIM content service Autodesk Seek. Here’s what Autodesk has to say about the reason for this change:

Autodesk… does not consider the Autodesk Seek service to be strategic to our core business at this time.

 
The timeline went something like this:

  • 16 January 2017 – Autodesk transferred the operations and customer support obligations related to the Autodesk Seek business to Swedish digital content company BIMobject.
  • 18 January 2017 – Autodesk posts a notice to that effect on its Knowledge Network.
  • 18 January 2017 – BIMobject posts a notice to that effect on its own site.
  • ~23 January 2017 – Autodesk customers attempting to use Autodesk Seek find out about the change when they are automatically redirected to the BIMobject site.
     
  • ~23 January 2017 – A well-known Autodesk personality also finds out about the change, unfortunately while presenting Autodesk Seek to a crowd. I’m sure the consummate professional in question would have handled this situation well, but it’s an uncomfortable position to be placed in.

It may well be that former Autodesk Seek users are not unduly inconvenienced by this change. This transition may be less stressful for customers than, say, Autodesk deciding to get out of the Facilities Management software business. Time will tell.

Autodesk can and will dump products and parts of its business as and when it sees fit, as it always has. Look back over Autodesk’s history and you’ll observe a long trail of corpses and weeping orphans. The difference with Cloud software and services is that very negative changes can take immediate effect. The vendor has total control; the customer has none.

Even if your Cloudy product is Autodesk’s Next Big Thing, that’s no protection. If Autodesk loses interest, the rug can be pulled at any instant, with unknown consequences. If you’re not uncomfortable with that, you should be.

When Autodesk dumped FMDesktop, customers could at least continue to use the software they had for as long as they liked. From the customer’s viewpoint, that’s the huge advantage of the desktop software perpetual license model; an advantage I can’t see customers giving up willingly.

Battle of the Bullshit part 3 – Beyond Bentley

Somebody at Autodesk really does seem to have it in for Bentley right now. I thought they were friends? Oh well, times change.

Autodesk has launched a campaign to promote its BIM offerings for transportation projects and is promoting this via emails to existing customers, all of which is fair enough. It’s suggesting BIM is a better tool than traditional CAD for such projects. Another reasonable claim, so it’s appropriate for us to evaluate the arguments and examine the options.

What did Autodesk decide to call its campaign? Beyond AutoCAD? Beyond CAD? To BIM and Beyond?

None of the above. It’s Beyond Bentley.

Huh? You may have noticed I’m keen on alliteration, but still, huh? What does Bentley have to do with this? Most Autodesk CAD customers are going to know and care nothing about Bentley products. So why mention them at all? The headline is “Move beyond Bentley to Autodesk, the makers of BIM”. The strong implication is:

Bentley only does traditional CAD. You should use BIM instead, and that means you need Autodesk.

However, I believe many Autodesk customers will think like this instead:

Autodesk seems very concerned about this Bentley mob. I wonder what they’re offering that has the Big A so worried? Bentley must be a big player in this area. I’ve been considering developing an Autodesk exit strategy anyway because of the forced rental thing and I’ve heard Bentley sells perpetual licenses. I must go check them out!

Those customers who do check out Bentley will learn that despite Autodesk’s implication, Bentley do in fact provide BIM products, and quite a few products specifically for transportation. I have no idea if Bentley’s BIM and transportation products are any better or worse than Autodesk’s offerings, but I do know you shouldn’t take either vendor’s word for it, including anything they say in webinars. Find out for yourself with a hands-on evaluation. Because BIM isn’t something you just pop in and out of, make sure you include long-term licensing costs into your calculations.
