This Blog is dedicated to all things to do with Building Information Modeling.
I'll be blogging about challenges that I come across as BIM Manager as well as points of interest that are related to BIM. Blogs on tips and technical "How-too's" to help you out with creating your BIM models correctly.

Impress your clients by creating a simple walk through or walk around
or the project.
Here I'll show you the basics of how to create a walkthrough, you
can improve you walkthroughs by manipulating the settings.
Start by going to the plan view, either the top view of a 3D View
or a floor plan view. For this example I'm going to work in a 3D view.
On the View drop down
select the Walkthrough icon.
This will then bring you into the Modify/Walkthrough ribbon.
Start by looking at the Option
bar for camera options, here you'll be able to make your camera views a
Perspective or not, set the offset from your level and also select the level.
I typically choose 5'-10" Offset which is close to my eye
height. sometimes I make it really high (like over 25') which gives you the
impression of looking down onto your model.
Then picking camera points along the path you want to take.
Then select the Edit
Walkthrough icon to activate access to the cameras, the little red icon in
front of the camera controls the direction of the camera and the blue circle controls
the depth of the camera.
Go through each Key Frame
and adjust the camera depth and angle, you don't have to do this for each frame
just the Key Frames.
Open Walkthrough icon to open the camera view.
Here you can change the Visual
Style to either Shaded or Realistic and turn off the crop region
You can also play the video and make any changes required. click
anywhere on the screen to exit the walkthrough editor and to reopen the walkthrough
editor right click on the Walkthrough
title in the Project Browser and
select Camera. With the editor open
you can switch from camera view to plan view etc.
To create a path
that moves the camera up or down Edit the Walkthrough and change the controls
on the Option Bar to Path, now you can go into a elevation
or 3D view and manipulate the camera key frame points either up or down.
When your done and ready to export your Walkthrough you need to have
your walkthrough view open then go to the Export
option under the Application Icon as
Pick Walkthrough, this
will then open up a dialog box where you can manipulate the length, Visual Style
and dimensions of the video.
Then another dialog box will pop on Video compression, I typically
select Uncompressed to get the best results but you can play with this to
reduce your file size and type.
There you go!
You've created a walkthrough video....
Next look at some of the options like Slowing down sections of Frames under the camera properties,
altering the length of the video or un-checking Perspective on the Options Bar.
Happy Auatralia Day for all my Aussie rellies and Friends...
Here are some fun facts about the Land Down-unda....
On the 26th of January, 1788, The First Fleet of 11 ships
with 1500 aboard, half of them convicts from Britain,
arrived at the south eastern shores of Australia. The town of Sydney grew from that
first small, British penal settlement. Australia day commemorates this.
On 1 January 1901, the six colonies federated, forming
the Commonwealth of Australia.
The flag of
Australia is a defacedBlue Ensign: a blue field with the Union Flag in the canton (upper hoist quarter), and a
large white seven-pointed star known as the Commonwealth Star in the lower hoist quarter. The fly contains a
representation of the Southern Cross constellation, made up of five white
stars – one small five-pointed star and four, larger, seven-pointed stars.
Waltzing Matilda" by
Banjo Paterson is Australia's
most widely known bush ballad. A countryfolk song, the song has been referred to as "the unofficial
national anthem of Australia".
The title is Australian slang for travelling by
foot with one's goods in a "Matilda" (bag) slung over one's back. The
song narrates the story of an itinerant worker, or "swagman",
making a drink of tea at a bush camp and capturing a sheep to eat. When the
sheep's owner arrives with three police officers to arrest the worker for the
theft, the worker commits suicide by drowning himself in the nearby watering
hole and then goes on to haunt the site.
Australia produces 95 per cent of the world's
precious opals and 99 per cent of its black opals. The world’s opal capital is
the quirky underground town of Coober Pedy in South Australia. The
world’s largest opal, weighing 5.27 kilograms, was found here in 1990.
Kalgoorlie in Western
Australia is Australia's
largest producer of gold. It also embraces the world's largest political
electorate, covering a mammoth 2.2 million square kilometres.
Queensland’s Great Barrier Reef is home to the world’s largest
oyster, weighing up to 3 kilograms, while the world’s longest earthworm,
stretching up to 4 metres, is found in Gippsland in Victoria. The heaviest crab, weighing up to
14 kilograms, is found in Bass Strait near Tasmania. Australia’s tallest mountain is Mt
Kosciuszko, which is 2,228 metres above sea level. The
world’s longest piece of straight railway track stretches 478 kilometres across
South Australia’s vast, treeless Nullarbor Plain. Australia’s
longest stretch of straight road - 148 kilometres – is on the Eyre Highway in Western Australia. It’s
just a tiny portion of the 2,700 kilometre sealed road that takes travellers
from Perth to Adelaide. The world's longest continuous
fence – the dingo fence – was built to keep sheep safe from Australia's native dog and runs for 5,531
kilometres through central Queensland and South Australia.

kangaroo is unique to Australia
and appears on our coat of arms. It is a mammal and a macropod, a family of
marsupials that includes wallabies and pademelons. Kangaroos are the only large
animals to travel by hopping and breeding adult males often fight by boxing
with their front paws and kicking their back legs. There are 55 kangaroo
species spread across Australia.
are small, dark-brown, furry, egg-laying mammals with webbed paws and a
duck-like beak. Platypuses live in burrows which they dig into the banks of
rivers. They are diving animals, and can stay under water for up to fifteen
minutes. Unlike a duck's beak, the platypus' beak is rubbery and flexible. It
has hundreds of electroreceptor cells inside it, which can detect the
electrical currents that are caused by its prey swimming through the water.
Platypuses can be found along Australia’s
eastern coastal areas in small streams and quiet rivers.
Australian Coat Of Arms has on it a kangaroo and an emu. The reason for this is
that the kangaroo and the emu cannot go backwards but can only walk forwards.
Here's something that I just discovered....I guess I need to look
a little closer as I don't think it's a new feature!
I was working on an existing window family making some
modifications by adding some parameters to make the window more "Flexible".... Anyway I
discovered that you can convert existing Type
Parameters into Instance Parameters
simply by simply checking the "Instance
Parameter" check box on the option bar after you have selected the
Parameter dimension.. Sooo easy!
Here's an example....
Here I converted a Type
Parameter that controls the Mullion height into an Instance Parameter.
For this window I also made the vertical mullion an Instance
Parameter (but note, I had to then add a reference plane to re-establish the
center of the window) so now I have total control of the Mullions for each
instance of this window.
A colleague where I work showed me this trick as he was creating
signage for a car dealership that required a colour face with white sides. This
process doesn't use the Model Text tool in Revit.
Here's how it's done...
1: Import a JPEG image into AutoCAD and trace the outline of your
text or logo. I used AutoCAD because I have access to it and I find it easier
to sketch lines but you could do the same process in Revit.
2: Import in your Cad file into Revit and do a full Explode so you
can access the linework.
Select all the lines and use the Cut to clipboard tool to save the lines on the clipboard.
3: Open a New Family Template based on the Generic Model Face Based file.
Paste from the clipboard your linework and move into position as
4: Start the Extrusion
command and using the select linework sketch tool pick the linework you just
Set your depth on the options bar and then hit the green checkmark to complete the task.
Assign a material to your Sign, this is now the base of your new
5: Go to a side view, select your Sign and create a copy
(remembering to unconstrain) and change the depth of the copied sign (I chose
Change the material of the copied sign and move to the top of the
other one. There you have it... Insert your sign as a
component into your Revit Project and place your new sign on the wall of your
Here are the basic steps on how to unload your Add-in tools.... handy to know...
Fill in the blank #### depending on what year version you are using, ie: If your using Revit 2012 input 2012 where I have shown ####
Firstly Close Revit. Yes I know it sounds stoopid but you'll be surprised how many times I have tried to monkey around with the program while I have it open.....
Then llocate the following folder: for windows Vista and windows 7: C:\ProgramData\Autodesk\Revit\Addins\#### For Windows XP - C:\Documents and Settings\All Users\Application Data\Autodesk\REVIT\Addins\####
Move the add-in files from the folder above to another location. I created a folder in my add in folder called temp files and dumped the add-in files into that using the cut function.
Start Revit and your add-ins will be disabled. When testing is complete move the add-in files back into the original folder.
