Will Revit users fly with this device?

An in depth review of the 3D Connexion The SpacePilot™ PRO has been carried out by Michael Anonuevo over at Club Revit and its worth a look if your interested in what these gadgets can do.

"The SpacePilot™ PRO _ a product review by Michael Anonuevo
(Disclaimer: I am in no way connected to 3Dconnexion. I wasn’t asked to write this review nor was I compensated.)
One of the new features of Revit Architecture 2012 is its support for 3Dconnexion devices. As a Revit beta tester, I was aware of this feature before this version was released. However, prior commitments prevented me from taking a look into it until last month. Anyway, here are my findings:
The first thing I did was visit 3Dconnexion’s website to learn about their products. In the internet, I read a lot of articles and reviews concerning their product line. Apparently, they have been around since 2001. Their products are popular in the manufacturing industry as navigation tools in CAD/CAM modeling and simulation applications. In the film industry, they are used for navigation and visualization with popular animation software such as Maya, Alias, Blender, etc. Although Autodesk is officially supporting 3Dconnexion’s products, I couldn’t find any information on how they are being used in Revit. A lot of product reviews by design engineers have affirmed their usefulness though. Nonetheless, I was a little bit skeptical. The regular mouse, after all, does a good job as a navigation tool in Revit. My thought then was to get hold of a unit and test it.
Not knowing anything about 3Dconnexion’s navigation devices, I contacted them. I sent an email with my credentials and asked if I could evaluate and review their SpaceNavigator. Within a few days, I was contacted and informed that the company was sending me the SpacePilot PRO. This is 3Dconnexion’s top of the line model.
For Revit Architecture 2012 users, this article is about my experience with the SpacePilot PRO in the two weeks that I put it to various tests. Aside from Revit, I also tested the device with Autodesk Inventor 2011, Photoshop CS5, and Google Earth. I’ve included a few photos and video clips to help you make a decision if you’re contemplating on buying one. I will probably write a follow-up article after I use the device extensively for a few months". Read the full article here...

Modelling Floor Finishes–The FAST way!

Great blog from Joe Stott over at Revit Scratchpad showing a highly innovative way of creating floor finishes in a Revit model.  Something which has baffled many people for a long time. I think although this is a workaround, this really is a workable solution and would like to see it become a specific tool in the next release of Revit.  Thanks Joe!

"Well, after a little Twitter banter between myself and David Light last night regarding modelling floor finished I appear to have spent the day trying to figure out how we can model floor finishes within our projects efficiently. I say efficiently because this is something we have tried before but found it to be pretty labour intensive and a little too similar to polylining in AutoCAD for my liking. Previous attempts of modelling floor finishes using thin floor types proved painfully slow and inflexible.. Whilst this approach did achieve its purpose of providing us modelled floor finishes it entailed endless updating when things changes such as wall build-ups. When this happened we had to modify the sketch of the floors to match the new wall face (and yet we could of locked it but i hate locking the model down too much).

The alternative to this would be use the room parameters to provide floor finish information which is OK but only gets you so far. As soon as a room contains more than one finish (which they almost always do) this method either becomes overly complicated or else breaks down completely.

So, my cunning plan is to model the floor finishes in each room like the floor type method but this time using ceilings instead of floors…. Yes, that does sound a little daft i know but honestly, I think its going to work a treat and here's why..."

Wookiees and Hamsters

Ok so go with me on this one...

I was asked in a training session the other day how to control the position of jpeg images imported into elevation views within Revit. Straight away I was on the internet trying to find some sample images to use as a demonstration. The samples I found made the group laugh so I thought I would use the same images when blogging about it.

Images imported into Revit can be brought in using the Decal or Image icons on the insert Tab. There are distinct deferences between the two.

Decal: Allows an image to be placed onto a 3D planar surface within the model but only displays the image if the view is rendered.

Image: Allows an image to be brought into a 2D view and displays in all views except for 3D and rendered views.

The screen shot below shows a series of walls all staggered in depth.  I've imported an image of what appears to be a giant Hamster and by default, when placing the image it is set to background. The Hamster peeps over the wall!

It is possible to change the position of the image but the available options are quite limited.
Select the image, in the instance properties you will find an option to adjust the draw layer. You can change it to foreground.

The Hamster jumps in front of the walls and is displayed in the foreground.

The problem with the Hamster being in the foreground is that the image has a white background and masks out the walls (so it doesn't look normal, well... as normal as a giant Hamster on a wall could be).

If you want images to display in the foreground, the solution is to use images with transparent backgrounds. The .png file type supports transparent image backgrounds and can be loaded into Revit.

Ok so now I need a .png image with a transparent background so I can demonstrate how the images look. Back to the Internet again! The first thing I found was a clan of Wookiees. Good enough!

Here you can see the Wookiees have been loaded into the scene and set to foreground. Notice there is no background and they blend in naturally with the wall (honestly).

So there you have it, Wookies and Hamsters in a Revit blog. I'm pretty sure this is a first.

Obviously if you apply these techniques to your building elevations you will realise that you can now load in people, trees, cars etc using the Wookiee technique, and for a Sky or background image use the Hamster technique. All without the need to export your images to Photoshop for final editing.
