Using Dunn Edwards Colors in your Revit Project

March 6, 2012

Update 08-17-13:

I recorded a How To on getting Dunn Edwards paint colors into your Revit project materials browser, which is located on the arch-intel.info web site.   Sam at D.E. sent me the spreadsheet which has the RGB values, which is also available.  There are two w-clips on this page.  The first shows how to create the materials in Revit. The other w-clip has two parts: one accessing the Excel spreadsheet, which is available through the Arch-Intel Dropbox. and the second on how to create a new Dunn Edwards paint materials directory in Revit with an adsklib file I’ve created and is also available through the Dropbox.

Update 03-07-12:
Luke Johnson over at the “What Revit Wants” Blog (link in our side bar) suggested an alternative to Photoshop.  http://www.getpaint.net/ which is a free program that should give you similar capabilities to Photoshop.  You can find out more by checking out Luke’s blog at :

Much Thanks Luke!! (CK)……………………………………

I’ve also used Artweaver which is available at: http://www.artweaver.de/download-en/
Make sure you download the free version.  (CK)

RPC Content (People, Vehicles & Plants) – Trouble Shooting

December 10, 2011

Archvision (http://www.archvision.com/) provides a variety of content for populating your renderings with people, vehicles and plants. A typical installation on a single machine usually doesn’t present a problem but if you are working in a large office with your Revit files on a main server you are going to have to address some pathing issues.

The problem arises when you are working on a project and you load the RPC content from the server. Archvision uses a series of files to direct Revit on how to render the content placed within the Revit project. These files are (or should be) located within a folder called “ArchVision Content Manager” under the local path of C:Program Files/ArchVision folder. These commands direct the Content Manager to look for the RPC image files at the following local path:

C:\Program Files\Common Files\Autodesk Shared\Materials2011\assetlibrary_base.fbm\RPCs

So if your image files are stored on the server and the Content Manager is looking on the local machine for the image files, which are not there, the RPC’s will not render. The big clue that there is a disconnect is your RPC’s will look like cubes rather than the wire mesh of vehicles or paper cutout profiles of people or plants.

The cube below is a Mini-Cooper (or should I say a Mini-Cuber) before the image file path is re-established.

The easy fix is to copy the desired image files from the server onto the local machine to the asset library address referenced above.

For some reason Revit Arch 2011 doesn’t immediately see these image files so you may (will) need to close and restart Revit to see the new image files. It may be that Revit populates the ArchVision image content to Revit at startup rather than going directly to the file source each time you are re-pathing the image. Whatever the reason this is the only way I’ve been able to see the new image content.

Also the RPC’s may not automatically update with the proper image files when you restart the project. So if you have to re-path the image files because they won’t render or they still look like cubes just select the failing RPC note the name of the RPC in the Properties dialog. Select ‘Edit Type’ then ‘Rendered Appearance’ button. An ArchVision dialog window should open showing you all the local image content available for your RPC’s. Select the image of the same name as your RPC to re-path. You should see the outline of the cube change to match the image when you back out of the edit dialog.

I’ve been told by ArchVision that the Content Manager can be located on the server to circumvent this issue. Just one more thing on my list of a 1000 that I need to do. Hmm this is probably 957.

Happy Rendering

Resolving Network License Issues in Revit 2012

Revit 2013 RPC Content Disappears with Realistic Mode Setting: 
I’ve had this issue with my 2008 Toshiba laptop and it appears to be a Video card compatibility problem.  If you enter the Options button under the Purple ‘R’ (upper left corner of Revit interface) and proceed to the “Graphics” area you’ll notice (if your graphics card is suspect) an “Unknown Video Card” caution.  If you uncheck the “hardware acceleration” under “graphics mode” then close and reopen your project you’ll notice that your RPC content will no longer disappear under the “realistic” view mode but at the same time it will not render.  So it appears the video card may be at odds with the realtime RPC render aspect of the “realistic” view inherent in this Revit enhancement. At least with my NVIDIA Quadro NVS 150M video card.

Deciphering Revit Light Intensity

May 1, 2011

Light fixtures and the light they produce can be somewhat of a mystery.  When you enter into the ‘Type Properties” of a light fixture the primary control for the light intensity can be found under the button to the right of the Initial Intensity parameter.

Once you’ve activated the dialog select the “Wattage” radio button.  You are now faced with two inputs.  You will need to know three things to complete these inputs. 

1.  The number of lamps in your fixture.
2.  The wattage of each lamp.
3.  The initial lumens produced by each lamp.

The first value “wattage” is achieved by multiplying the number of lamps times the wattage to get the total fixture wattage.

The second value “Efficacy” is acheived by dividing the lumen value for a single lamp by the wattage for that individual lamp.  So a 17 watt lamp producing 1275 lumens has an Efficacy of 75.

If you are creating a light fixture, you want to make sure the color temperature matches the lamp type and the light source is of a similar light distribution pattern that matches the lamp configuration.

Here are some sources for lamp data.

PROJECT PHOTOFLY: 3D models from photos.

December 28, 2010

AU2010 Premier:
“Capturing the reality as-built for various purposes (renovation, energy analysis, add-on design, etc.) is now becoming possible using your standard digital camera thanks to advanced computer vision technologies developed by Autodesk, called Camera Factory, and now made available through Project Photofly

Project Photofly is a technology preview of automatically converting photographs shot around an object or a scene into “Photo Scenes” using the power of cloud computing.

The Photo Scene Editor executable will operate until August 1, 2011.”

Try Rendering as a Service

June 28, 2010

Autodesk Labs Technologies Project Neon is serving up a new concept in rendering your drawings.

Overview:

Project Neon is a rendering service that offers greater productivity and a faster turnaround of photorealistic renderings by leveraging the power and compute capabilities of the cloud. Rendering is a time and hardware intensive process that translates 3D models into photorealistic images that allow the design team to optimize the results they deliver to their clients. By harnessing the power of the cloud, customers no longer you have to wait for long periods of time to generate single or multiple views of their designs, The Project Neon service eliminates the need for customers to purchase and maintain expensive hardware for their rendering needs. Providing a realistic view into designs during the entire design process delivers superior results for your customers.
