CAD Nostalgia Video

For the first video in the new cad nauseam YouTube channel, I’ve had a bit of fun. I unearthed a bunch of my old stuff to show you. Does any of this take you back? Enjoy!

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 …

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, …

AutoCAD 2018 licensing crash – another reason to avoid subscription

Autodesk has released an update to fix the following AutoCAD 2018 problem:

Product users of version 2018 Autodesk single-user subscriptions may experience an intermittent crash. The crash occurs when it has been more than 24 hours since the last successful authorization check and there is intermittent or no internet connection, or the licensing authorization server is unavailable. The licensing authorization check occurs in the background and is completely unrelated to activities the user is performing at the time of the crash.
A fatal error message may be shown by the product. For example:

FATAL ERROR: Unhandled e06d7363h Exception at ee563c58h

 
Links:

Note that this crash only afflicts subscription (rental) single-user (standalone) customers. People with perpetual licenses don’t have to put up with the multiple additional points of failure caused by the subscription licensing system insisting on phoning home every 30 days. Yes, even if you pay for three years’ subscription up front, you’ll still need a working Internet connection every 30 days if you want to keep using the product.

At least, Autodesk has been saying it’s only once every 30 days (as if that wasn’t bad enough). The information provided with this hotfix tells a different story. What is the license server doing phoning home 24 hours after the last successful authorization check? Enquiring minds want to know.

No criticism of Autodesk is implied for providing this hotfix. As always, I commend Autodesk for fixing up problems as they arise. The basis of my criticism is the hotfix being necessary in the first place. It’s caused by Autodesk inflicting unnecessary complication on its customers for its own internal reasons. This one fails the “how does this benefit the customer?” test big-time.

The single-user subscription licensing mechanism has been a crock from day one, especially for CAD Managers of multiple users who have to deal with its onerous requirements. It’s an astonishingly poor design, very badly implemented. Even with this particular crash fixed, it’s still a crock.

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.

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 …

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 – 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 …

Huge PDFs? AutoCAD 2017.1.1 could be to blame

Autodesk has yet again demonstrated why continuous automatic updating is no panacea for avoiding CAD update disruption. On the contrary… If you have noticed some of your PDFs exported from AutoCAD getting huge and unwieldy lately, AutoCAD 2017.1.1 could be to blame. Try uninstalling it using Programs and Features > View Installed Updates and see if the problem goes away. It may also be possible to work around this by going into PDF options and turning on Include Hyperlinks. Source: The Swamp. Here’s one possible* install history: You install AutoCAD 2017. This defaults to also installing Autodesk desktop app. If …

AutoCAD 2017.1.1 Update

Thanks to Jimmy Bergmark, I now know that the controversial subscription-only* AutoCAD 2017.1 Update has itself been updated. Jimmy was brave enough to install and run the execrable Autodesk desktop app and discovered the update update. Rather you than me, Jimmy! Here’s the readme. You’ll need to get at it using Autodesk Account. I note that a bunch of crashes are fixed by this update update. Perhaps that is related to the magical missing AutoCAD 2017.1 crash information? Who knows? The update was apparently released over a month ago on 17 November 2016. Autodesk needs to work out an alternative …

BricsCAD startup LISP bug fixed

In my previous post I have a real problem with BricsCAD, I related my then-latest interaction with the Bricsys support system: Steve Johnson 05-12-2016 05:30 UTC I don’t know if this is a BricsCAD problem or a DOSLib one, so I am reporting it to both Bricsys and Dale at McNeel. I’m also not sure if this was happening in earlier versions. If I load DOSLib during an S::STARTUP call and then use the (dos_msgbox) function later in that call, this fails the first time round because BricsCAD things the function is not defined. Opening a second drawing results in …

Draping images over surfaces in Civil 3D

Having recently overcome various difficulties to successfully drape an image over a surface in Civil 3D, it may be useful to pass on a few points I have learned. There are various posts and videos out there that helpfully go through this process, but some of them (including Autodesk sources) contain information that is irrelevant or just plain wrong, and none of them contained all  of the information I needed to complete the task. I used Civil 3D 2015 for this, but the principles apply to all recent releases. Here is the basic sequence required: In the drawing containing the …

AutoCAD 2017 Service Pack 1 is out but you probably don’t want to install it

As reported by Jimmy Bergmark, AutoCAD 2017 SP1 will break add-ins that use Autodesk’s built-in autoloader mechanism. It looks like it’s a problem caused by third party applications, but it’s not. It’s entirely Autodesk’s fault. The only fix at this stage is to uninstall SP1. It’s astonishing that Autodesk would release a service pack like this, introducing a nasty bug that will break customers’ existing functionality. This reminds me of the comedy of errors that was AutoCAD Release 13 with its multitude of updates, many of which introduced new bugs as well as fixing others. AutoCAD 2017c4a, anyone? If you needed …

How to break Civil 3D 2013

In Civil 3D 2013 (with or without hotfix 2.1), use the PLOT command and use the Window option. While being prompted for the window corners, use the middle button mouse wheel to zoom to locate the exact point you want. Civil 3D then enters a loop in which it displays: Document “drawing name” has a command in progress. Hit enter to cancel or [Retry]: At this point, the user can do nothing with the program. Hitting Enter, Esc, R, etc. or doing more all do nothing except cause the message to be redisplayed. Picking a point or further wheel zooming …

AutoCAD 2012 drawing mangler hotfix

In AutoCAD 2012 and products based on it, saving the drawing while in the block editor can result in your whole drawing being replaced by the block you’re editing. As this can be somewhat inconvenient, it’s probably a good idea to download and install Autodesk’s hotfix for this problem. As always, read the readme first.
