Have you ever wanted to ‘re-issue’ or revise a large group of sheets such that they all receive the same, updated revision in the Revision Schedule?

Lets say you have 100 sheets and these form the ‘Approval’ set of documents – how do you go about amending and reissuing them?

For significant revisions, it is our company policy that all revised sheets have the same entry in the Revision Schedule. Therefore, we use the following method (it takes a little setting up the first time, but it is worth it):

  1. On the first sheet you would like to re-issue, create a small section of Revision Cloud that is associated with the appropriate revision in from the Sheet Issues/Revision dialog box.
  2. Select this small section of Revision Cloud and Group it into a detail group. Call this group whatever you like – something like ‘Approval Revision Set 1’
  3. Select the Detail Group and Ctrl-C (copy to Clipboard)
  4. (At this point we usually Hide the Revisions from the sheet by Tab-selecting the Revision Cloud and Hide Category in View, as we don’t really use Revision Clouds in the traditional sense)
  5. Go to the next sheet in the set and Paste-Aligned
  6. Repeat this for each sheet you would like in the ‘Revision Set’ (you will notice that as you do this, a new entry appears in the Revision Schedule – as you would expect)

Now, you can quickly re-issue that entire set. How?Just edit the ‘Approval Revision Set 1’ Detail Group that you created, and:

  • Add a new piece of Revision Cloud that is associated to the appropriate entry in the Revision Schedule. All your sheets have now been issued with the new entry, and the Revision Schedule on each sheet shows the new entry!

You can do some tricky things with ‘nesting’ these Detail Groups to give you more flexibility or add new sheets to sets.

One of our staff found a bug for Schedule editing in Revit 2010 64 bit. If modifying a Schedule (in our case a Door Schedule) and you change a ‘Type Property’ and then go straight to the ‘Close’ button in the Schedule (without changing cells or tabbing or anything), Revit will tell you “this will change all instances of this xxx type” and then if you click ‘OK’, Revit will crash.

Here are the steps to reproduce this issue (keep in mind that we are running Revit 64 bit on Vista 64 bit):

  1. Create a schedule that includes Type Properties that you can directly modify.
  2. Open the schedule.
  3. Modify the Type Property.
  4. Using your mouse, click the ‘x’ or Close button in the top right corner of the schedule window.
  5. Revit will provide you with a dialog box – Click ‘OK’.
  6. Revit crashes.

See if you can reproduce this.It would be wise to Save your project before trying!

As I go about my day-t0-day, I come across some very good free programs (some of which I have posted about before – see links at bottom).

Most recently, I have come across the following free utilities:

  • FreeFileSync – for comparing directories
  • RichCopy – very powerful copying utility, for things like network backups etc. Replacement for Robocopy + GUI
  • InfraRecorder – free burning and ISO creating utility
  • Mozilla Thunderbird – just goes from strength to strength. I have used it to connect to our Exchange database at work.
  • GRemote – this utility allows you to control a PC using a Windows Mobile device as an emulated mouse. Can connect either using WiFi or Bluetooth. Useful for Media Centre and Presentations.
  • Microsoft Security Essentials – free antimalware and antivirus program with real time scanning from Microsoft.

Hope you find these helpful!



I encountered a problem today related to walkthrough creation in Revit 2010 64 bit with Vista 64 bit. I was exporting a large walkthrough to uncompressed AVI format, and the file size would reach 4.00 GB (4,294,967,296 bytes), and then corruption of the AVI would result. It appears that a 4 GB limit was being imposed at some point in the walkthrough creation process.

Therefore, I tried to use an encoding format. When using Revit 32 bit, I recall that I had a number of options in the Video Compression ‘codec’ dialog when exporting a walkthrough. However, in Revit 64 bit, I only had a couple of basic options (Microsoft Video 1, Intel IYUV Codec, Full Frames (uncompressed)).

After some searching, and trialling a few different ideas, I found that I could access some decent codecs in this box after installing Shark007’s 64 bit components (link below).

64 bit Encoding Components

In addition to the above, it is recommended that you install Shark007’s 32 bit Codec Pack (link below):
Vista Codec Package 5.5.3 Final

After installing both of the above and restarting Revit (you may also need to restart Windows), I was intermittently able to access an additional filter in the dialog called ‘ffdshow’ – clicking ‘Configure’ opened up a whole range of encoding formats for use!However, there appear to be a few problems:

  1. The ‘ffdshow Video Codec’ encoder only appeared in the Video Compression dialog when a certain ‘Size Crop’ and resolution were selected. For me, the only settings that consistently seemed to work were: Size Crop width = 150 mm, and export resolution 886 x 500.
  2. The corruption still seemed to result if the uncompressed AVI format would have exceed 4 GB (even while using a compressed codec).
  3. Choosing H264 actually crashed Revit.
  4. WMV 8 using libavcodec simply did not proceed past the first frame.

Given the above limitations, my solution at this point is:

  1. Split the walkthrough into parts that have a size less than 4 GB (ie. part 1 = frames 1 to 100, part 2 = frames 101 to 200 etc) and use FULL FRAMES (UNCOMPRESSED) AVI format.
  2. Use VirtualDubMod to ‘append’ these segments together, and
  3. Use VirtualDubMod to ‘Save As…’ a different format. I was able to choose ‘Cinepak’ compression in VirtualDubMod, which turned my approx 5.4 GB uncompressed AVI into a 167 MB file in only about 5 mins of processing time.

After spending quite a few hours trying to make this work in a satisfactory and simple manner, I decided to contact our reseller and lodge a support call. I will let you know if I learn anything helpful.During this investigation, I tried a few things without success. They may be of interest to you (see links below).

Just came across this search engine for PDF, DOC and PPT files. It is called http://www.osun.org/


For example, lets say you wanted to see what PDF files are available that include the words ‘ revit families’. Have a look at the results by following the link below:

This could be a very useful site for quickly searching for quality data. If Google can’t find what you are after, give this site a go.

I’ll be the first to admit that the subject of this post was intended to stimulate your interest – but in my defense I did include question marks!

Have a look at this link, and see if you can make sense of it:

Any comments?
