A collection of over one hundred new and enhanced AutoCAD commands developed over the years. They are mainly aimed at the architectural drafting operator, concentrating on turning out efficient design development and contract documentation drawings. However, Yerfdog is applicable to other fields also, since many of the commands have general application. You should be able to make substantial performance gains in daily AutoCAD use if you use this system.
They are written for AutoCAD versions 2000 to 2017. AutoCAD Architecture is also supported, as is any Autodesk CAD software which supports Visual Lisp. Users of Release 14 and the various versions of AutoCAD LT are out of luck, however. This is because Yerfdog uses Visual Lisp, which is not provided with that software. However, if enough people want it, an R14 version could be forthcoming.
Yerfdog has unofficially been used for many years at a number of sites. People have been asking for a copy and, so as to avoid work as much as possible, this web site has been set up for anyone to use. Enjoy!
Nothing!
It is intended that the system will be marketed either free of charge or at a very low price to the local architectural community. At the moment, there is a preview version available as a free download. Because of this, no warranties or guarantees can be made and support is limited to email only. We do of course welcome feedback.
If you have any queries or problems, send us an email and we will try to help, free of charge. Should you require personal help to set it up or to run it, onsite assistance is available in the Melbourne (Australia) area. There is, however, a small charge for this. Contact us at the address below for more details.
We will be producing a complete operating guide to Yerfdog, but for now, refer to the Command Summary for brief descriptions of the commands. A partial menu is also available, which makes it easier to find your way around the system.
There are a huge number of commands; just take your time and, at first, use the ones most useful to you. Every now and then, browse through the Command Summary and experiment with new ones.
When you download the current version, you are authorised to use it for twelve months. There will be updates issued during the year and you are encouraged to check this site for updates on a regular basis. As updates are issued, they will have authorised "use-by" dates further into the future. This is so that you are using the latest and greatest versions at all times. Again, there is no charge for these updates. If you wish we can send you, by email, notification of significant updates. Our email address is listed below.
Download the files yerdog.vlx, yerfdog.ini and alias.lsp. The links to these files are at the bottom of this page. Place the files yerfdog.vlx, yerfdog.ini and alias.lsp in your AutoCAD support files search path. If you like you can create a "yerfdog" directory for this purpose. The search path is found in the Tools/Options/Files pulldown menu. Load yerfdog.vlx and then alias.lsp, using either Appload or just dragging them into an AutoCAD drawing window from Explorer.
Alternatively, the method we recommend is to customise your acaddoc.lsp and add the following lines:
(load "yerfdog.vlx")
(load "alias.lsp")
This will load Yerfdog every time you open a drawing. If you haven't got an acaddoc.lsp, don't worry. The default AutoCAD installation doesn't include it. Just create it as a text file, with a .lsp extension using Windows Notepad and place it in your support directory.
Alternatively, a sample acaddoc.lsp is provided below for you to download. Edit it in a text editor to suit your needs.
If you have problems with error messages about files or functions not being found, the most likely cause is that your Support files search path is not set correctly. Also, note that yerfdog.vlx needs to be loaded before alias.lsp, otherwise you will get really informative AutoCAD error messages like (stringp nil).
If you wish you can download and install a partial customisation file (.CUI or .CUIX file) for your version of AutoCAD. These contain some ribbon customisations for you to play with. If you do this, I'd appreciate some feedback on what you think should be in these ribbons. If you create your own, please let me know and share a copy if you can.
Don't hesitate to email us if you come up against any dramas when installing Yerfdog.
Yes, almost certainly, you can. We have gone to some considerable trouble to ensure that the internal functions and variables which Yerfdog uses are unique. Please let us know if you find any clashes.
If you feel that you would like to use only some and not all Yerfdog commands, then that should not cause problems either. Simply edit alias.lsp and comment out any commands that you do not need: this is achieved by placing a semi-colon (";") at the start of the line. Alternatively, more advanced users can change the names of the commands to whatever they wish. Email us if you need a hand with this.
Yes, you can! Many Yerfdog settings, for example layer keys, are determined by a simple ASCII text file called yerfdog.ini. Feel free to edit this in a text editor if you wish. Windows Notepad works fine. You will need to close and reopen your drawing to see the changes, though.
