RAID on the Cheap: Windows 7 Software RAID

Luke Johnson

Here’s an idea – if you have two old but similarly sized hard drives sitting around, plug them into your Windows 7 PC and create a Striped Volume.

Striping increases the access speed of the drive.

This could be useful when working on a local version of a Revit central file – local disk access speed becomes important in this situation.

Here’s how:

  1. Plug the two extra hard drives into your PC.  Then turn the computer on…
  2. Go to Disk Management (right click on ‘Computer’, then go ‘Manage’)
  3. Delete all unnecessary volumes from these extra drives.
  4. Right click on one of them – New – Striped Volume
  5. Basically follow the prompts – make sure you pick the two correct drives to become part of the Striped configuration.
  6. Choose quick format / NTFS Default allocation size
  7. Enjoy the increased speed of your striped volume.

Please be careful with this process – make sure you understand the pro’s and con’s.  If you do, it can be a inexpensive way to increase your performance while using Revit.

This guy did a comparison on the speed of Windows 7 ‘Striping’ vs hardware RAID0 – and surprisingly, the results were similar.

Engineering giant GHD adopts Autodesk's BIM offering

Luke Johnson

A $5 MILLION deal with Autodesk will underpin the growth plans of Australia’s GHD, one of the world’s largest engineering companies.

Key to the contract renewal was a new licensing model dubbed MultiFlex, allowing every GHD user, no matter their location, to rely on a single agreement.

…

Under the deal GHD will be able to access 25 Autodesk products, an increase from 15 applications previously.

Using Avisynth and VirtualDub to join BMP to AVI

Luke Johnson
  1. Download Avisynth and install it.
  2. Download VirtualDub and unzip / install it.
  3. You need to have a set of BMP files with sequential numbering.  Refer to this post for how to do that.
  4. In the folder containing the bitmaps, create a text file.  Call it READ.AVS (it must have AVS extension).
  5. Open it in Notepad and put the following line into the file:
    ImageSource(“%04d.bmp”, start = 1, end = 1800, use_DevIL = true)
  6. The above syntax is for files with 4 digit filenames, starting at 0001.bmp and ending at 1800.bmp (obviously, if you have more or less frames, change the 1800 value accordingly).
  7. Open VirtualDub
  8. Open the READ.AVS file that you created.
  9. Now you should be able to save this file from VirtualDub to an AVI.  Here is some quick settings:
    Video – Direct Stream Copy
    Audio – No audio
  10. Go File – Save as AVI
  11. Put your AVI somewhere with plenty of disk space – it could become huge.

Distributed Parallel Rendering in Revit

Luke Johnson

Are your renders taking ages?  Trying to output a big rendered walkthrough?  No matter how fast your PC is, these things can take time.  Why not enlist a few of the other computers in your office to help produce that high-resolution animation?

Distributed rendering (or Parallel Rendering) is possible when using high end visualization products, including 3D Studio (now part of the Building Design Suite Premium).

In pure Revit (without using 3D Studio), the solution is a little bit more crude.  However, it does work.

Here are the basic steps:

  1. Set up your walkthrough.
  2. Save the Project or Save to Central.
  3. Get your other computers running and open the same walkthrough on all of these PCs.
  4. On PC#1 in Revit, go to Export – Animation – Walkthrough, and pick a set number of frames for that PC to output.  For example, frames 1 to 600 out of 1800.
  5. Make sure you choose BMP for the output, and when naming the file, just put in 1- (this will make sense later.
  6. On PC#2, export frames 601 to 1200 to BMP.  Name it 601-.
  7. On PC#3, export frames 1201 to 1800 to BMP.  Name it 1201-.
  8. Using Advanced Renamer, rename all the files to suit the appropriate frames. (see associated post)
  9. Put all the BMPs in one folder on the server or on one of the PCs.
  10. Using Avisynth and VirtualDub, join the BMPs into an AVI. (see associated post)
  11. Then, either use some video compression software, or do some post-processing.

There you go, you have successfully done some distributed or parallel rendering in Revit!
