You will also find a new snap type called “close”. Why “close” you may ask? The new close snap allows you to close a valid open loop of elements whilst you are sketching, if you have more than one option to close the loop, just use the Tab key to snap through the different options.
Finally, choose “close” from the Osnap overrides list. This will complete the loop of walls. Remember, if you have more than one option to close the loop, just use the Tab key to cycle through the different options, until you find the one you require.

The same model migrated across in 2009 shows the same geometry but now you can use the fill pattern tools on the warped and freeform faces.
There seems no way to adjust the rotation of the pattern in the view, but you can set up a custom hatch pattern with a rotation already applied to match the surface.
If you take a look at the wall below you will see that using the modified hatch pattern with a rotation included; the pattern now runs parallel to the surface as you would expect.

Once you’ve sketched the extent of the pad, you can add a slope arrow which is accessible from the design bar when you are in sketch mode.
You can control the slope of the pad by accessing the element properties, where you can either specify the height at tail or the slope. To do this, select the slope arrow and right mouse click and go to element properties.
This added functionality will certainly help to enhance your site modelling capabilities within Revit Architecture and Structure.
Finally, another little tip-bit for building pads in 2009, is that they are now considered to be room-bounding elements and this is especially useful when calculating room areas or volumes.

So to model a swept blend using the massing tools, you do the following…
Go to the massing tools in the design bar.
Name your mass and then choose solid swept blend, from the Solid Form tools. This will take you into the sketch mode allowing you to create the various parts which will make up the swept blend.
We will start by defining the path. You can either Pick Path or Sketch a path; your path can consist of a line, arc, spline or ellipse. Unfortunately your path cannot contain more than one arc. Sketch your path and select finish path from the menu.
You should now have something which looks like this.
All you now need to do is select Finish Swept blend from the design bar to form the geometry.
Finally, select Finish Mass to exit out of the Mass tools.
The new Swept Blend tool will allow you to create geometry like this…..
Another challenge in the past was to create a spiral piece of wall to infill under a spiral ramp or staircase. Click on the image below to open a movie example....Or select this link Swept Blend movie example where I explain how to achieve this using the new swept blend as a piece of void geometry which I subtract from the main wall.

The 32bit version....
The 64bit version.....
but be warned, its a heavy download!!!!

When you are in a 3d view or perspective, you will notice an additional tool in the view control bar. The new teapot icon allows you to quickly access the render dialogue box. Alternatively, you can still access the render tools from the design bar or pull down menu.
The new layout of the render dialogue is excellent, it’s simple to use and understand. Somebody at Autodesk has really listened to what the architect and designers requires when it comes to rendering images.
Revit Architecture 2009 also includes render preset such as draft, low, medium, high and best allowing you to get quick results. However, you also have the ability to drill down and create your own custom setup for a particular view if you want too. In general, increasing (or turning on) any one of these settings increases the quality of the rendered image. Increasing these values or multiple settings may increase render time exponentially, so you’ve been warned!! But on a positive note, if you have a dual core or quad core processor in your workstation or laptop, then the Mental Ray render will make use of these extra cores. One thing I did find was that there was no way I could transfer custom setting between views, which is a shame. I am sure someone will enlighten me if I have got it wrong.
All lighting fixtures are now photometric and will use an IES file to define lighting parameters. If you open an existing light fitting family you will notice that you have the ability to specify the IES file for the light fitting. Revit Architecture 2009 uses this information from the IES file to define the geometric shape of the light source.
The materials provided within Revit Architecture 2009 have been reassigned Mental Ray material properties. These materials are far more realistic and are stored as part of the project file. If you go to the materials dialogue box, settings pull down menu>materials, you will notice that this dialogue box has been overhauled. The render appearance tab allows you to control the settings for the material you want to define. Revit includes a library of standard materials, but you can also define your own custom materials if you want.
Revit Architecture 2009 has also simplified the process for creating different lighting conditions. You will find preset for the following conditions:-
Exterior : Sun only
Exterior : Sun and Artificial
Exterior : Artificial only
Interior : Sun only
Interior : Sun and Artificial
Interior : Artificial only
So to test these I produced a very simple scene which you can see below. I then render the scene a number of times using some of these presets.
Exterior - sun only
Exterior - artificial + sun
Interior - only
Interior - sun + artificial
Interior - sun only
Overall, I am very impressed with the new rendering engine. I am positive that new and existing users will get to grips with this tool and its settings very quickly and I am expecting to see some excellent images from the Revit community in the not too distant future.

Firstly, start by duplicating level 1 and renaming that SITE.
Next open the SITE view, right mouse click in view and go to view properties from the contextual menu. Then scroll down until you find View range and edit the View range changing it to read….
Top: Associated (Level 1) offset 100000.0
Cut plane: Associated (Level 1) offset 100000.0
Bottom Level Below offset 0.0
Level: Level Below offset 0.0
Freewheel was released a few years back by Autodesk as an experimental technology and it first appeared on there Autodesk Labs website. I tried it when it was first released and it seemed a bit slow, but over the last year or so it has been improved and it now seems to come in two flavours, Project Freewheel and Autodesk Freewheel, you’ll see what the differences are at this page....
One smart feature with Autodesk Freewheel is that you can embed the viewer into your web pages allowing you to display interactive 2D and 3D CAD designs without requiring your visitors to download special viewing software. Autodesk provides sample code on how to do this at the Autodesk Freewheel site. So I was keen to see if I could embed the code that Autodesk provide on my blog site to display Revit DWF drawings interactively. All I needed to do was produce a DWF from Revit, host that on my website and then using the code Autodesk provide, I adjusted the code so that I pathed it to the DWF on my website, I then added the adjusted code to this blog.
This seems like a great way to display Revit drawings and images interactively on the web. If you interested in how it was achieved, I recommend going to ....
In a future blog, I'll take a look at what Project Freewheel has to offer for the Revit user.
