Free Online Generic BIM Object Library #01

Trying to find free BIM Objects online? here comes resource number 01
Català - Castellano - Deutsch
I have started to scan the web in search of good BIM object Libraries. I have found some interesting ones so I'll keep posting them here. The first one I am sharing is a generic object library by BIMsmart (Reed Construction Data). It serves the purpose to populate your model with some basic objects. See a preview below.


Of course the goal of BIM is not (only) to generate a 3D of your building, so if you are trying to go into more detail, like calculating costs out of your BIM model you'll need to use manufacturers BIM Objects / Families, or add cost dimensions to these generic objects.

Engage Investors with BIM

Six reasons to use BIM to engage investors in your project
Català - Castellano - Deutsch
Reedconstructiondata has recently published an article to try to answer the question "How can BIM, Building Information Modeling, effectively communicate the design of a new multi-sport facility in order to engage investors in financial participation?". The article, as I see it, gives the main 6 reasons why you should adopt BIM in your firm as soon as possible.

The six given reasons, summarized, are the following:

1. In ten years developers will have adopted BIM and will request it
2. It lowers project costs
3. It allows better Design, Visualization and Contract Documents
4. It reduces "Design Waste", specially if IPD is also adopted
5. It allows to incorporate Facility Management tools that will reduce the operating costs of the building
6. For the above mentioned reasons, BIM will produce a better product (the building) with higher ROI

I think they are key reasons to go for BIM. BIM is not (only) a new tool with better functionality and capabilities compared to traditional CAD Programs, BIM is a new process in itself and part of a bigger process that is already revolutionizing the construction industry. It's time to embrace BIM and embrace the transformation towards a more efficient construction industry.

Autodesk's BIM Deployment Plan

Autodesk has a public BIM deployment Plan. A very interesting read.
Català - Castellano - Deutsch
Autodesk has published a "BIM Deployment Plan" Document. The Paper, 42 pages long, explains in detail the strategies to adopt to implement (deploy) BIM in your company. As explained in the executive summary:

"The Autodesk BIM Deployment Plan outlines practices and provides a framework for using building information modeling (BIM) technologyand practices that can help to deliver projects faster, more cost-effectively, and more sustainably".

I am just in the process of going through it and will add to this post more details in the future. For now I'll just share the link for those with more time than me. Please feel free to comment.

Just got this forwarded from a friend. A free tool to model your home interiors for free, with an interactive 3D view to visualize what you are easily modelling in plan. See the following video.


I wouldn't use it for serious stuff, but I think it can be a nice tool to play with to introduce kids to 3D or for those who feel themselve 3D challenged but want to give it a first try. Very simple to use, with many options and you can use it without even installing a single piece of software. It can be run from your browser on the cloud.
Try it here. Thanks Chait for the link.

Google Building Maker: Model for Google Earth without SketchUp

Model Buildings for google earth using your web browser.
Català - Castellano - Deutsch
Google has a new tool to crowdsource the 3D modelling of the earth. It is called Google building Maker, and it allows users to model Buildings from pictures that Google itself provides. See this video to understand the process.


It seems a pretty brilliant idea on the path of making the modeling of buildings available to everyone. Of course Google will get cash out of your free labour, but still, it is worth a try just for fun. Try Building Maker Here.

From CAD to BIM: Part I - History of CAD

A brief history of CAD to understand the path that led to BIM
Català - Castellano - Deutsch
I mentioned on a previous post my intention to go into BIM and IPD. Unfortunately for now, I have not the luck to be working on a daily basis with either, so my initial approach here will be more theoretical. I am trying to build the basis of what my Master Thesis is going to be, so forgive me if sometimes things sound a bit basic or repetitive.

BIM, as I see it, is still Computer Aided Design, but it allows you to add an “n” number of dimensions (like costs, scheduling, etc), and strongly modifies the work process to design, build and maintain a building. But since it is in my point of view an evolution of CAD, I think it is important to start with brief history of CAD.

In 1957, Dr. Patrick J. Hanratty had developed the first commercial CAM (Computer Aided Machining) program. It was a numerical control (NC) machining software developed in Pronto , the first NC commercial programming language. Hanratty is regarded as the father of CAD / CAM since these two branches became slowly one.

The first CAD software with a graphical interface was Sketchpad, developed in 1963 by Ivan Sutherland. Sketchpad was a Program in which the user could graphically interact with the program through a screen, a light pen used to draft, and a set of buttons that allowed the user to enter parameters and constraints. Although it never became commercially available, the ideas on Sutherland´s PhD dissertation became highly influential for future generation CAD developments.


First-generation CAD software systems were 2D drafting applications developed by a manufacturer's internal IT group and primarily intended to automate repetitive drafting tasks. During the 1960s, Hanratty himself developed DAC, a CAD system, while working for General Motors Research. Other companies like Ford (PDGS - 1967), McDonnell-Douglas (CADD - 1966), and many others followed soon after that.

During the 1970s the transformation from 2D to 3D began. The French Aerospace Company, Avions Marcel Dassault, developed CATIA, after purchasing a source code license from Lockheed Martin. CATIA is still nowadays leading software in the Aerospace, Automotive and Shipbuilding Industries. One of the most important research dissertations of the decade was K. Vesprille's (at Syracuse University) 1975 PhD dissertation "Computer-Aided Design Applications of the B-Spline Approximation Form" on Complex 3D Modeling. It is from the end of this decade that one of the first books marketing CAD for architects appeared. “Computer Aided Architectural Design” by William J. Mitchell from 1977 is a hint that CAD was already being marketed to architects. The widespread adoption by architects would take still years.


During the 1980s the CATIA, Pro/Engineer, Unigraphics and I-DEA became the leading CAD software packages. All of them powerful 3D modeling software systems with their core business on the industrial production (for this reason sometimes referred as CAE systems rather than CAD) and their main hardware platform being UNIX. On the 2D and PC Platform Autodesk, with AutoCAD, was gaining market share.

It was on the 1990s, that the PC explosion happened and with it the raise of a new player. Autodesk had been focusing on the PC platform since its AutoCAD version 1 released in 1982. The licensing of the ACIS 3D Kernel, allowed Autodesk to release in 1993 AutoCAD Release 13. For the first time AutoCAD had 3D Solid Modeling Functions. AutoCAD became widely spread, but other packages like Bentley’s Microstation, soon became strong competitors on the mid-price market. The widespread adoption of CAD by architectural offices was happening slowly and soon would burst into being the dominant trend. We will see more on that on the next post on this series

Photoshop: Shortcut to select all the contents of a layer

Select all layer contents wit a single click
Català - Castellano - Deutsch
When working with Photoshop sometimes we might want to get a selection of the entire content of a layer. This is useful for man reasons. An easy way to do this is to go to the layers tab and click on the thumbnail of the layer with the left mouse button while holding CTRL (I guess command key in MAC??)
If you point at the layer thumbnail with your cursor and press CTRL, you will see how the cursor will change from a pointing hand to a pointing hand with a marquee on top. This means that when you click there instead of selecting the layer as active, it will use the contents of that layer to create a selection.
This is very useful to create selections based on the shapes of layers such as texts. See this example that I created using this method. From the following two images...



...i used the one on the right with the multiple CAD-Addict.com texts to create the selection using the explained method. Then, I used the slection to erase parts of the layer on the left. The reslult is as follows


This is a very useful trick to speed up you workflow in pshop.

AutoCAD: Load LISP and Applications Manually or Automatically

Hot to load LSIP routines and other applications
Català - Castellano - Deutsch
I wrote recently some posts about using LISP routines to speed up certain tasks. I forgot to mention, how to load these Files. The manual way is to use the command APPLOAD. This will call the Load Application Dialog Box where you can browse for the saved LISP.



Alternatively, if it is a LISP that you use regularly, simply drag and drop it into the icon saying Startup Suite in the APPLOAD dialog box. This will make the LISP or application load automatically at start of the AutoCAD session.

Excel: Turn numbers exported from ACAD into European Format

There is a quick way to turn numbers in Excel into European format and to remove apostrophes.
Català - Castellano - Deutsch
European Number Format, uses a coma as a decimal separator instead the period of the English format. When exporting data from AutoCAD to Excel using the DATAEXTRACTION command, the numbers exported are in English format, so to transform them to the European Format we need to replace the points for comas. This can very done very easy by using the find and replace function in Excel. Type CTRL + F or click the Replace button on the Editing area of the Home Tab (Excel 2007). Find Points and replace them by comas, and select Replace All.


There is an extra step needed if we want to be able to use the data from AutoCAD in Excel as numbers. All the Cells exported from CAD start with an apostrophe ('). See below.


This makes the numbers not usable as such. Luckily there is a trick to batch remove this sign. If you have a column with numbers, insert a new column to its right. On the cell next to the first number in the row enter the follwing fórmula.


Where D2 is the Cell with the numbers with the apostrophe you need to eliminate. Then copy the cell next to all numbers you want to transform. You will see now the result of the formula as the number you want to use. Something like this:


The left cell is the one still containing the apostrophes, and that is why the numbers are aligned to the left. The one on the right is the result of the formula we have applied.

A final step I would recommend is to copy all these new cells and paste them in a new column using Paste Special. Paste Special can be accessed after copying some cells by right clicking on a cell. Then On the Paste Special Window Select "Values".


That's it, now you can delete the other columns (the one with the apostrophes and the one with the formulas, and you have just the new column with plain numbers. The explanations is long, but the process takes lest than a minute.
