The BLADE video watchlist

Leave a reply

I did my third and final (for now) BricsCAD Unplugged webcast about BLADE last Wednesday. Here’s the video:

Before I dig into DCL, I start with a brief description of an absolutely brilliant feature that was added to BLADE in V19. If you code in LISP, you’ll love this feature.

Then I move on to some ancient history. Did you know that we can thank the far-sightedness of some slightly renegade Autodesk OS/2 developers in the early 1990s for the dialog boxes we use today? Did you know that you could program dialog boxes for AutoCAD for Mac in 1993 but you can’t today? Can you spot the items of interest in the background?

The rest of the video is dedicated to describing DCL programming and debugging, and I explain how BLADE is the best tool for that job using examples.

If you want to watch all three of the BLADE videos in a row (that’s 1 hour 49 minutes of viewing), Matt Olding has created a YouTube playlist for this series.

It has been an absolute pleasure working with the Bricsys people in putting this series together. Torsten Moses has informed me about yet another bunch of enhancements that are coming very soon to BLADE, so maybe you haven’t heard the last from me on this subject on BricsCAD Unplugged.

More BLADE videos

As mentioned previously, In December I made a guest appearance on the BricsCAD Unplugged webcast series to discuss the LISP development environment, BLADE (YouTube link).

I made another appearance last week describing debugging using BLADE (YouTube link):

If you’re dealing with LISP code for AutoCAD and/or BricsCAD, you really should be doing it in BLADE. It’s the best development environment for AutoLISP/Visual LISP that you’re ever going to get.

I have another appearance scheduled for later today (13 February) in which among other LISPy things, I will be discussing using BLADE for DCL programming. Again, even if you’re AutoCAD-only, I believe this is worth a watch. BLADE is better for DCL programming, too.

Even if you’re AutoCAD-only and not a programmer, you might find my brief ancient history lesson of interest. Did you know that BricsCAD for Mac users can thank a far-sighted early 90s Autodesk OS/2 team for the dialog boxes they use today?

The BricsCAD Unplugged webcast broadcasts run on the Bricsys Facebook page and are then quickly transferred to YouTube. Today’s session will start at about UTC 14:15 (2:15 PM) on Wednesday, 13 February 2019 (click here for your local time)

Video – who is that masked man?

Last night I made another guest appearance on the BricsCAD Unplugged webcast series. This time I was discussing the LISP development environment, BLADE. Here’s the video:

Bonus points will be awarded for identifying three items of interest in the background. No, not counting my dog Sunday asleep at lower left.

Despite going way over time, there was still nowhere near enough opportunity to describe the full LISPy awesomeness that BLADE represents. I am therefore scheduled to return for another two or three episodes beginning in February. In those, I’ll be doing more of a step-by-step demonstration rather than the overview and V19 new feature description I did in this episode. If you have any particular requests for what you want covered, please comment on this post.

I also showed how the tools in BLADE (e.g. the (inspector) function) are still worth having for any DWG-based CAD Manager or power user, even if you’re not a full-on LISP programmer. If you have to work out what’s going on with dodgy DWG files, you’ll want to have (inspector) in your set of tools.

The BricsCAD Unplugged webcast broadcasts run on the Bricsys Facebook page and are then quickly transferred to YouTube. This was the last episode for 2018 because of Christmas and New Year.

Wielding BLADE on BricsCAD Unplugged

In September I was the special guest on the BricsCAD Unplugged episode BricsCAD Unplugged – Steve Johnson 5 surprises moving to BricsCAD. Next Wednesday I will return, this time to wield BLADE, the best thing to happen to CAD LISP in nearly 20 years. I’ll be introducing it and demonstrating a few things, including the new features that came with V19.

These live broadcasts are run on the Bricsys Facebook page and are then quickly transferred to YouTube. This broadcast will start at UTC 15:00 (3 PM) on Wednesday, 19 December 2018. Here’s that time in a few handy time zones:

Video – Steve on BricsCAD Unplugged

Leave a reply

Following on from Lynn Allen and Robert Green’s guest appearances on the BricsCAD Unplugged webcast a couple of weeks ago, this time it was my turn.

Last night (my time) I was the special guest on the episode BricsCAD Unplugged – Steve Johnson 5 surprises moving to BricsCAD. I’m introduced at 2:12 and appear at 3:30. Here’s the full video:

In this week’s episode, you’ll witness:

  • Me discussing the five biggest things that pleasantly surprised me about BricsCAD. (I have more than five, but time was limited).
  • Don Strimbu bribing me with drinks containers.
  • An actual printed copy of Cadalyst magazine from 1995, complete with my old column Bug Watch (1995-2008).
  • The excellent euphemism, “You’re generally pretty conservative in terms of your praise.”
  • Don throwing me a curveball by introducing my points out of order!
  • The announcement that I’ll be at Bricsys 2018 in London and possibly participating in the BLADE session.
  • Me saying, “No. I’m wrong.”
  • Me drinking a glass of wine (parental guidance advised – alcohol consumption depicted). If you care, it’s a Shiraz (that’s Syrah if you’re American) from South Australia’s Limestone Coast region.
  • Total lack of coordination from everyone in raising our drinks at the end.

Thank you to the Bricsys crew for the invitation, it was a blast! If you ever want me on again, I’ll be happy to oblige.

For future reference, these live broadcasts run on the Bricsys Facebook page and are then quickly transferred to YouTube.

CAD Panacea tip – startup files in BricsCAD

3 Replies

One of the things that might initially baffle a CAD Manager or power user when investigating switching from AutoCAD to BricsCAD is how to set up the startup routines. Head over to CAD Panacea for R.K. McSwain’s concise, handy description of how to do it.

Due to BricsCAD’s high level of compatibility, you can maintain a common folder or set of folders containing LISP and other custom files for both applications. That way, you don’t need to do double maintenance during the transition period. I’ve done this successfully in a highly complex custom environment. Some code and other adjustments were required in places, but all but a handful of my hundreds of AutoCAD LISP files worked as-is in BricsCAD with zero effort.

Having added your AutoCAD custom folder(s) to BricsCAD’s search path, I suggest you make a common startup LISP file (e.g. rename your old acaddoc.lsp to something like CADStartupDoc.lsp) and have tiny stub startup LISP files for each application (acaddoc.lsp and on_doc_load.lsp) that each loads the common startup file.

acaddoc.lsp contents:
(load "CADStartupDoc")

on_doc_load.lsp contents:
(load "CADStartupDoc")

You can add error checking and messaging if you like, but if you have control of your environment you probably won’t even need that. If you find you do need any application-specific code, you can just add it or load it from the acaddoc.lsp or on_doc_load.lsp stubs as appropriate.

Setting your application or document window size using LISP

1 Reply

I intend to produce a few videos containing tips, tutorials, product comparisons and the like. I’ve set up a cad nauseam YouTube channel, but don’t bother visiting it yet because it’s empty.

One of the things I need to do for these videos make sure I’m capturing the screen at an appropriate resolution. I knocked up a bit of Visual LISP to take care of this task quickly and accurately, and you might as well have it. It’s a simple routine that allows you to accurately size either the main AutoCAD application window or the current document window (drawing area) within the main window.

The file is WindowSize.lsp. It should work in all full AutoCAD releases (not counting LT and AutoCAD for Mac) and AutoCAD-based verticals from 2000 on.

It works in recent BricsCAD releases (except the free and LISPless BricsCAD Shape). I’ve only tested it in Windows, but it should also work in the Mac and Linux versions due to the high degree of LISP compatibility provided even across platforms. It also works in ZWCAD 2018 for the main application window, but don’t use it on the document window because that doesn’t work.

Download it, put it in a location of your choice and load it into your CAD application (for example by dragging and dropping it from Explorer onto the drawing window).

Note: In AutoCAD 2014 and later, loading any LISP or other executable file may result in a warning depending on the release, the security settings, whether the file is located in one of AutoCAD’s trusted locations, and whether the file is digitally signed. I’ve digitally signed the file to reduce the incidence of warnings, but you could still see something like this:

The verified publisher should be cad nauseam as shown above. If you pick Always Load then you shouldn’t see the warning again for this file or any others signed by cad nauseam. Feel free to edit the file for your own needs, but if you do the signature will become invalid and you’ll be warned again when loading the file.

Once it’s loaded, enter the command WindowSize. The prompt sequence goes like this:

Command: WINDOWSIZE
Window to size [Application/Document] :
Width in pixels <1280>:
Height in pixels <720>:

Now, back to work on the first of those videos.

AutoCAD 2009 – The Prequel Part 18 – Another Interface Option

5 Replies

There’s one screen-based user interface mechanism in AutoCAD 2009 that you probably won’t see bragged about in Autodesk marketing materials. That’s a shame, because it has some strong points:

  • It can be docked on the side of the screen or allowed to float free.
  • While floating, it can be resized to the desired width and height.
  • If you do dock it on the side, any unused height can be used to place either docked or floating toolbars.
  • Out of the box, it provides access to a large number of the most commonly used AutoCAD commands.
  • In default form, it is context-sensitive, providing you with the options relevant to the command you’re using.
  • It can be modified (using CUI, unfortunately) to provide access to any commands or macros you like, using a tree or sequential structure as you see fit.
  • The interface reacts more quickly to user input than the Ribbon or Menu Browser.
  • Rather than cryptic graphics, it uses plain text labels that are easily understood. This is particularly useful if you have a block library where part numbers are used to identify parts that are visibly similar to each other.
  • It provides an interface that users of old AutoCAD releases will be instantly at home with, and I mean old.

Have you guessed yet?

AutoCAD 2009 Screen Menu

I seem to remember first hearing about the imminent demise of Screen Menus around the Release 12 timeframe. I wonder how long they can survive into the 21st century?

Autodesk deserves credit for keeping stuff like this going after all this time, a long time after it has gone seriously out of fashion. I’m sure the amount of resources it consumes is minuscule compared with the more modern interface elements. I know there are still some people who have a use for screen menus, and the same applies to image menus. All the tablet stuff is still there too, although I haven’t tested it.

Seriously, I’m more impressed by Autodesk’s retention of the Screen Menu than I am by the introduction of, say, the Steering Wheel. Autodesk is unlikely to brag about it, but maybe it should.
