DOSLib goes open source

What’s DOSLib? DOSLib is a free library of LISP functions that adds a lot of functionality to AutoLISP/Visual LISP/BricsCAD LISP. It makes a lot of programming tasks a lot easier, because instead of writing a bunch of code to do tricky stuff, you can just load the library and call a ready-made (dos_xxx) function. There are hundreds of functions that cover the following areas (taken from the McNeel Wiki): Drives – Check for drives, change between drives, and check available disk space. Paths – Manipulate path specifications. Folders – Create, rename, remove, select, and change folders. Return special operating system folders. Files – Copy, …

Mac users rejoice – at long last, a LISP IDE comes to OS X

CAD’s best LISP development environment has come to the best “AutoCAD for Mac”. It should come as no surprise to anyone that this has occurred without Autodesk’s involvement. What’s happened? With the release of BricsCAD (Mac) V18.2 (currently V18.2.23-1 to be precise), BLADE (BricsCAD’s much-superior equivalent to VLIDE) has been added to BricsCAD See here for the release notes and here to download. Make sure you select the Mac version: Significance This is pretty significant for anybody serious about using DWG-based CAD on the Mac. AutoCAD without LISP is hardly worthy of the name, which is why I’ve never been …

Steve’s BLADE presentation at the BricsCAD New Zealand and Australia Roadshow

Sofoco (Australia) and CAD Concepts (New Zealand) recently ran a series of seminars throughout Australasia demonstrating BricsCAD. I attended the last of these in Brisbane on April 19 and gave a presentation about BricsCAD’s LISP, with reference to AutoCAD compatibility and the tools available to CAD Managers and developers, including BLADE. The talk was aimed at anybody who is writing or maintaining LISP code for AutoCAD or BricsCAD. I had the just-before-lunch slot, which is never desirable for a presenter. People are dozing off and/or bursting to go to the toilet, and time adjustments have to be made if earlier …

BLADE – putting things back to “normal”

Disclaimer: I’m making money using BLADE. I’m using it on a paying project right now (well, not while I’m typing this, but you get the idea). I’m developing a routine to automate a massively repetitive task for one of my AutoCAD-using clients, and I’m developing it in BricsCAD and BLADE rather than AutoCAD and VLIDE. I can simply develop faster in the more modern environment, and BricsCAD’s significantly quicker start-up time helps with that. So does the fact that the routine runs several times faster in BricsCAD, making testing the large data sets much more efficient. I’m getting paid on …

Interviewing the creator of BLADE – CAD’s best LISP IDE – part 2

This post continues my interview with Torsten Moses about BLADE, the new LISP IDE that arrived with BricsCAD V18.2. See here for post 1. Steve: I’ve noted before that BricsCAD execution of AutoLISP and Visual LISP is several times faster than AutoCAD’s. How does the new technology affect that performance? Torsten: All the new BLADE-related stuff doesn’t really affect normal LISP execution outside the IDE and debugger. The connection is made by a few callbacks, which take zero time in normal processing. Therefore there is also no chance of breaking things. The BLADE implementation is very safe, and performance remains …

Interviewing the creator of BLADE – CAD’s best LISP IDE – part 1

Easily the most impressive new feature of BricsCAD V18.2 is the new Visual LISP IDE, BLADE (BricsCAD LISP Advanced Development Environment). The lack of any LISP IDE has been a BricsCAD stumbling block for a while, dissuading CAD Managers from adopting BricsCAD to replace their stagnant and increasingly expensive AutoCADs. As I will relate elsewhere, Bricsys has not just caught up with Autodesk here, but has shot so far ahead it’s unlikely to ever be caught. BricsCAD’s BLADE is so superior to AutoCAD’s VLIDE in so many ways there’s really no comparison. Yet it remains highly compatible. I have personal …

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 …

How to sign your LISP files

This post follows on from Why digitally sign your LISP files? and How to obtain a digital signature to sign your LISP files. In the first post, I explained why you might want to digitally sign your LISP files. In the second, I explained how to obtain and install a digital signature. This third and final post in the series assumes you have done all that and now want to sign your files. There are two methods available to you, using a dialog box or command-line interface. Signing LISP using the AcSignApply.exe dialog box Autodesk has provided a utility called …

How to obtain a digital signature to sign your LISP files

In an earlier post, I explained why you might want to digitally sign your LISP files. If you decide to go ahead with that, then this post explains how you can obtain and install the digital signature you will need to sign your files. This is the most difficult part of the process and it involves spending money. Getting a digital signature Although you can make your own digital signature (there’s an Autodesk Knowledgebase article describing the process), there’s little point in doing this. You can sign your files, sure, but that signature won’t be seen as trusted by software …

Why digitally sign your LISP files?

After I mentioned in an earlier post that I had digitally signed the sample LISP file I had provided, this generated some interest. In this post, I’ll explain why you might want to sign your LISP files. In a later post, I’ll explain how to do it. These days it is standard practice for developers to digitally sign their code. Operating systems and applications are displaying increasingly scary warnings when coming across unsigned code. Here is an example of the sort of message you get when you load an unsigned LISP file into AutoCAD from a location that has not …

All major Autodesk products on the Cloud by 2014?

As reported by multiple on-line news outlets, Autodesk just announced that it is increasing its research and development budget (having slashed it last year), and increasing the percentage of that budget on the Cloud. Carl Bass: When there are technology transitions in place, you better be more mindful of that, or you become roadkill. That’s fair enough. Autodesk would be stupid to ignore the Cloud, and needs to bet at least some of its cash on anything that stands a significant chance of being important. This quote from Autodesk spokesman Paul Sullivan gets more specific: We are devoting a larger …

Do you do any AutoCAD development?

Yes, that includes hacking about (or producing beautifully elegant code) in LISP. If so, you may wish to go here and fill in the appropriate API survey, which is probably the AutoCAD one. This year, Autodesk is opening up this survey, which used to be confined to Autodesk Developer Network members. I approve. ADN represents a tiny (but important) minority of fee-paying developers approved by Autodesk. I expect the results will be rather different if a significant number of “normal” AutoCAD developers notice this survey and fill it in. If you are, say, a LISP or VBA user and are feeling neglected, please go and …
