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 …

Setting your application or document window size using LISP

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) …

Why Bricsys makes the best AutoCAD for Mac

Bricsys has just released BricsCAD V18 for Mac. Here’s the download link and here are the release notes. BricsCAD V18 is an excellent DWG 2018-based CAD application, and the Mac version lacks little in comparison to the Windows version. It’s so much more capable than the perpetually half-baked AutoCAD for Mac that I struggle to comprehend why anybody with the choice would even contemplate the notably inferior and seriously overpriced Autodesk offering. That’s not just opinion, it can be supported objectively. Price first. US prices are shown here for a single standalone license over five years, inclusive of the cost …

AutoCAD 2018 for Mac – welcome to twenty years ago

In the past, I’ve described how AutoCAD for Mac was released half-baked (as I predicted) and has remained half-baked ever since. But wait! Autodesk has proudly announced AutoCAD 2018 for Mac. Skimming through that blog post, I must admit my jaw dropped when I saw some of the new features. This one, for example: This “new feature” was first provided to AutoCAD users in the 20th century. It was an Express Tool in AutoCAD 2000 (released 1999) and was absorbed into mainstream AutoCAD a few years later. The alias editor goes back even further, to the Release 14 Bonus Tools …

Tip: what to do when your text becomes empty rectangles

Dear person who used the search terms “writing has become empty rectangle in cad” and “autocad text has become an empty rectangle” on this blog, I suspect you probably have a drawing where QTEXT has been turned on. To fix this, enter QTEXT at the command prompt, set it to OFF, and if the problem doesn’t go away by itself then issue the REGENALL command. Pedantic note: the command name is QTEXT, but this controls a system variable called QTEXTMODE. QTEXT OFF is equivalent to both SETVAR QTEXTMODE 0 and just QTEXTMODE 0. In LISP it would be (setvar “QTEXTMODE” …

CAD-related Twitter exchange of the year

In a Twitter post (now deleted), the AutoCAD twitter account asks us to submit our feature ideas for AutoCAD, and links to the Autodesk Ideas Page: Just one problem. As R.K. McSwain points out in his reply, the Ideas Page has no section for AutoCAD. There should be one, and should have been one for years, but there isn’t. That tells you all you need to know about how the level of concern Autodesk has about AutoCAD’s future development. Here’s the exchange in all its glory: Oops.

First 2018.1-broke-my-AutoCAD reports coming in

Thanks to R.K. McSwain for pointing out that at least one user has reported unexpected shutdowns from AutoCAD (Architecture, probably) following installation of the 2018.1 Update. The problem went away following uninstallation of the update. Caveat updator. Anybody else have any issues or are you all waiting for the early adopters to find out for you? Edit: it turns out the crash occurs when opening 2013 DXF files. Edit 2: a hotfix has been posted here.

AutoCAD 2018.1 released, but only for some

Autodesk has released the AutoCAD (and LT) 2018.1 Update, not to be confused with the earlier ill-fated 2018.0.1 Update. It’s only available for currently-paying subscription and maintenance customers. The “non critical” bug fixes in this Update (by Autodesk’s definition) are being withheld from Autodesk’s other customers. Those of you who have allowed your maintenance to expire due to Autodesk’s development inaction and unjustified price increases can consider yourselves duly punished for failing to fall into line. If you have the execrable Autodesk desktop app installed (not recommended) and it works as expected, this update will present itself to you. Otherwise, …

Automated .NET 4.7 update kills AutoCAD pre 2017

Thanks to Robert Green for pointing this out: Microsoft is installing .NET 4.7 as part of their auto updates and it is causing many legacy Autodesk applications to crash on any ribbon interaction. Touch the ribbon, away goes your software. If you can keep from installing the 4.7 framework do so. If the damage is already done then uninstall .NET 4.7 and install .NET 4.6.2 using this download link. Note that the uninstall of the offending version must be done first! AutoCAD 2013 to 2016 and Inventor are affected, and possibly other products. BricsCAD users are unaffected. It is also …

AutoCAD 2018.0.2 arrives

AutoCAD 2018.0.1 is dead, long live 2018.0.2! Here’s the readme. Here’s the 64-bit direct link. Here’s the 32-bit direct link. This supposedly fixes stuff that 2018.0.1 broke, such as the signed VLX thing. Will this one break other stuff? I guess we’ll find out.

Bloatware – a tale of two installations

In a previous post, I showed that AutoCAD is bloatware by comparing the size of its downloads to that of BricsCAD. Obviously, an application that’s ten times the size it should be is going to cost you a lot of unnecessary bandwidth, download time and drive space. But maybe you don’t care about that. What practical difference does it make? Well, for one thing, the blimping-out of Autodesk’s former flagship product has a big effect on installation time. Vast and ever-increasing amounts of time are wasted by users of Autodesk products, just waiting for the things to finish installing. But …

AutoCAD 2018.0.1 mystery deepens with silent withdrawal

As I mentioned earlier, the release of AutoCAD 2018 was followed almost instantaneously by the first update, 2018.0.1. At the time of writing, there was no official information about this update. Some information was later made available, but questions remained. Now the update has been silently withdrawn. Go to Autodesk Account > Management > AutoCAD > Downloads > Updates & Add-ons and you will no longer see this: The infamous Autodesk desktop app also shows no sign of this update. So why has it been withdrawn? Autodesk isn’t saying, but thanks to Jimmy Bergmark, we know that installing the 2018.0.1 …

Bloatware – a tale of two CAD applications

You may have seen me mention in passing that AutoCAD is bloatware. That’s not just the general grumpy-old-user moan you see from long-term users like me, who can remember when AutoCAD used to fit on one floppy disk. Yes, programs get bigger over time as new functionality is added and old functionality needs to be retained. Hardware gets bigger, better, faster over time to compensate for that. I get that. Understood. The AutoCAD bloatware problem is much more than that. AutoCAD is literally ten times the size it needs to be, to provide the functionality it does. How do I know? …

AutoCAD 2018.0.1 mystery partially resolved but questions remain

As I mentioned earlier, the release of AutoCAD 2018 was followed almost instantaneously by the first update, 2018.0.1. At the time of writing, there was no official information about this update. Some information is now available, but more questions have arisen. If, like me, you don’t/won’t/can’t have Autodesk desktop app running on your systems, the only current official way to get at the download is using Autodesk Account (but read the whole of this post before you go there). That’s also how you get at information about the update. Go to Management > AutoCAD > Downloads > Updates & Add-ons. From there, …

AutoCAD 2018 – why did the DWG format change?

In my review of AutoCAD 2018, I had this to say about AutoCAD 2018’s changed DWG format: Why does AutoCAD 2018 need a new DWG format? It probably doesn’t. The 2013 DWG format is capable of holding pretty much anything you want… Although Autodesk cites performance reasons with certain drawings, I strongly suspect the new DWG format was introduced purely to make life difficult for competitors, and to encourage wavering customers to stay with Autodesk for fear of losing compatibility. In other words, it seems likely this is an anti-competitive change rather than a technical one. In a recent blog …

AutoCAD 2018 – disable InfoCenter

Here’s another AutoCAD 2018 download, just in case you haven’t had enough. If you want to disable AutoCAD’s InfoCenter (and you should, unless have a specific reason for keeping it – here’s why), go get the updated download from uber-expert Owen Wengerd’s ManuSoft Freebies page. It works for AutoCAD and AutoCAD LT.

AutoCAD 2018 – there’s already an update

If you downloaded and installed AutoCAD 2018 yesterday and don’t/won’t/can’t have Autodesk desktop app running on your systems, you may already have another download to do, because AutoCAD 2018.0.1 is out. At the time of writing there is no sign of this update on Autodesk’s main site, but you can get at it using Autodesk Account. Go to Management > AutoCAD > Downloads > Updates & Add-ons. All that’s downloaded is an executable. No readme, nothing. There is currently no official information about the reasons behind this update, what it includes, what it might affect, how to include it in …

AutoCAD 2018 – bear this in mind

Given the dearth of new functionality in AutoCAD in recent years, it’s understandable that Autodesk has taken to claiming credit for the same thing twice. The same features have been touted once for the 2017.1 mid-term update and again as 2018 new features. Even I fell for it, listing linetype gap selection as a 2018 feature in my original review. For the purposes of reviewing the earlier AutoCAD releases and AutoCAD 2018 as upgrades, I have included the 2017.1 features in 2018, not 2017. Some of those features are praiseworthy, and there have been some minor improvements to some of …
