I was interested in what I could find on Scribd to do with Revit – turns out there are some resources available. Have a look at some of the search results here:

Revit doesn’t want you to copy lines between Annotation and Model Families (see below)
However, it can be done. This is the workflow to copy lines from Annotation to Model families:
- Copy lines from the Annotation Family to a plan view in a Project File.
- Copy the lines from the Project File to a Profile Family.
- Copy the lines from a Profile Family to the Model Family.
Pretty tricky workaround huh?
Erik Egbertson over at Inside the Factory made a comment about modeling a Stealth Aircraft in a recent post, and it got me thinking. How would you go about it?
Now, I’m sure it would be possible to do it with the Conceptual Modeling tools, but it could take a while.
Why not utilise some existing 3D content and import it into a family? I described that workflow in my post Contextual 3D Views – Shaded vs Rendered. Basically, you need to:
- Download a Sketchup model that you like the look of (from http://sketchup.google.com/3dwarehouse/).
- In Revit, create a New-Generic Model family.
- Import the SKP file using Import CAD.
- Make sure the resulting geometry is of an appropriate size.
- Save the family and load it into your project.
Please note that there may be copyright on these models.So, about that Stealth Aircraft. Here is the link.
When you use the Join Geometry tool in Revit, you may notice that it sometimes just doesn’t seem to ‘work’. You do everything right, join the two adjacent surfaces – and there is still an ugly join line!
The problem is that Revit only wants to join surfaces correctly IF they are the same material. You could go into each object (floor, wall etc) and make sure all the materials are the same. However, the quick fix is shown below:
- Use the Paint tool to apply the same material to the two faces you want to join.
- If you have already ‘joined’ the surfaces, you need to unjoin them from each other. With walls, the easiest way to unjoin two objects is to physically disconnect the wall using grips (I do this in 3D). Revit will give you a warning – and you can then Unjoin the elements.
- Now, pull the objects back together, so they are in the same plane and they meet at a clean edge.
- Use Join Geometry again between the two surfaces – now that they are the same material, Revit is happy to join them properly, and it all works beautifully!
In short, Revit wants joined surfaces to be the same material before it will join them properly.
Occasionally you may find that the Finish Sketch and Cancel Sketch buttons disappear from the Ribbon.
The easiest way to get out of this situation is to map a Keyboard Shortcut for these commands. You can do this at any point (even after they have disappeared from the Ribbon). Simply open the ‘Keyboard Shortcuts’ dialog, and type ‘Finish Sketch’ in the box.
Then just map a suitable shortcut, like ‘FS’, to the command. As soon as you press OK, you can now use this shortcut to get out of the editing mode.
Revit wants you to understand it. It wants to be logical.
Sometimes you need to give Revit a bit of a hand. You may need to take a few simple steps to make Revit more understandable. David Light has some great tips along these lines over at http://autodesk-revit.blogspot.com/2010/02/point-colour-in-revit-2010.html
This is all part of being a smart Revit user – a few simple changes in Object Styles can give your modeling environment a whole heap more clarity.
Once you have modifed the Object Styles to suit your tastes, save these settings to a template file – so you don’t have to make the same changes each time. Be smart!
“Ribbon Hero currently works with Word, PowerPoint, and Excel (both 32/64 Bit) and it is only limited to Version 2007 and 2010 only. Once it is installed, there is a tiny green Ribbon Hero icon added in the Ribbon. When users start using the features in their Word, Excel or PowerPoint, they will start gaining points. Each feature and command available in the software has certain scores…”

Found some very interesting information on Wikipedia about 32 bit and 64 bit processor architecture – check it out (italics by me):
AMD licensed its x86-64 design to Intel, where it is marketed under the name Intel 64 (formerly EM64T). AMD’s design replaced earlier attempts by Intel to design its own x86-64 extensions which had been referred to as IA-32e. As Intel licenses AMD the right to use the original x86 architecture (upon which AMD’s x86-64 is based), these rival companies now rely on each other for 64-bit processor development. This has led to a case of mutually assured destruction should either company refuse to renew the license. Should such a scenario take place, AMD would no longer be authorized to produce any x86 processors, and Intel would no longer be authorized to produce x86-64 processors, forcing it back to 32-bit x86 architecture. However, the agreement provides that if one party breaches the agreement it loses all rights to the other party’s technology while the other party receives perpetual rights to all licensed technology.

Here is a brief how-to on creating a large, high resolution rendered Revit walkthrough (or sun study) and then subsequently compressing and uploading it to Youtube.
- Setup your walkthrough view.
- In Revit, Export – Walkthrough and divide the total frame count of the animation into parts that have a manageable number of frames (I recommend 100).
- Do this for each part of the Walkthrough (ie. create files with frames 1-100.avi, then 101-200.avi, 201-300.avi etc). Use ‘Full Frames (uncompressed)’ when creating these parts.
- Use VirtualDub to join the parts together. In VirtualDub, open the first part. Press Ctrl-Right arrow (this takes you to the end of the file), then go File – Append AVI Segment… and choose the next part. Do this however many times is need to append all parts to the original file.
- In VirtualDub, go to Video – Compression and I recommend using the ‘Cinepak Codec by Radius’ if you have it. Quality = 100.
- In VirtualDub, go to Audio and choose ‘No Audio’
- Choose Video – Full Processing Mode
- Now go File – Save as AVI and create your combined and partly compressed AVI file.
- Open Windows Movie Maker. Import the combined file into the collections.
- Drag the file into the storyboard at the bottom.
- Go to File – Publish Movie. Choose ‘This computer’ and click Next. Choose a filename and location and click Next.
- I recommend choosing ‘Best quality for playback on my computer’. This should reduce the file to a manageable size.
- Now, open your browser and login to your Youtube account. Choose ‘Upload’.
- Select the compressed video you have created, and upload it. This may take a while, so just wait patiently (or do some other work!)
- Once uploaded, you can now share the link code with Clients or others who may like to view the animation.
Below is an example of a 1000 frame rendered animation we recently produced at Dimond Architects. It started out at about 1.2 gb, then VirtualDub compressed it to around 225 mb, then Movie Maker compressed it to about 20 mb.It took about a week for one workstation to produce this:
