Revit Components.

More and more people are using Revit.  Great.  The goal of this site is to introduce people to Revit and hope that they will use it.  One of the problems I am seeing with this new rise of Revit users is the use of Free Revit Components.

Ah yes, free.  Everything in life is better when it's free. Right?  Not in this case.

We are all guilty of grabbing a component or two from RevitCity.com or other free component sharing sites.  The question is; How useful was that component?  It is very likely that the component you grabbed was not parametric, not exactly what you wanted, and looked like crap in one of the views (plan, section, or elevation).

I talked with some students in a design studio class at my school and they give me a look at their Revit models.  Of course, there were a few components that popped out like a sour thumb.  Freebies!  I asked them why they used the components.  They answered, "because I don't know how to make it" or "it takes to much time to figure out".  

Firstly, you're in an architecture program.  Take the time to make the components!  It will only make you better at Revit and understand the program much better.  It will also allow you to add the amount of information you need to that component.  It will allow you to create parameters that will be necessary to quickly adjust the size, material, light output, and etc... later on in the project.

Lastly, if you are going to actually extract information from your Revit model, such as energy analysis, then those components could play a crucial role.  For example, if you have a computer classroom in Revit there are over 30 computer, a projector, and lets add two 42" flat screen T.V.'s.  Anyone who has been around these three objects, especially the flat screen T.V., knows that they emit a ton of heat!  Don't you think this should be calculated when thinking about the heat loss or amount of heat needed for a space?  

Ultimately, I want my fellow students to not let the people who say "Revit is just a program full of built in components and restricts design freedom" be correct.  Let's not go the way of BIMpanzee's and CAD Monkeys.  Let us think deeper and farther out of the box.  Revit is not a drafting program.  Let's not use it as one.  

I hope this comes into your mind next time you are on RevitCity.com searching for a Mac that you can add to a desk that was already imported from a Revit model that was built in Revit 8.1.

Hi, Can anyone help me with creating roof windows eg Velux

Thanks in advance

True built-in components can restrict design if used exclusively, but don't you agree that it's a waste of time and money recreating components that have already be made. Custom modeling has it's place, and so does modifying. Revit needs to encourage more sharing of components - sketchup's warehouse has it figured. I'm at the end of design and trying to flush out a rendering with landscaping, the last thing i want to do is model every component just because revit doesn't have a broad enough range of tropical landscaping. Any suggestions?

Wow, I find it great that people are still reading posts I wrote from 2 years ago! First, thanks for checking the blog (however you might have gotten to this post). Being that it was written 2 years ago a lot has changed. Reading the post back I believe, and it is really my feeling now, that I am simply encouraging the creation of components. It is an incredible skill to learn and very valuable.

Now, with the traction Revit has gained the components have gotten so much better since I wrote this post. You can get many families directly from the manufacturer and MOST are very well done.

Today, I would like to use the post to simply warn you of the families you use. There are quite a few out there now and I have seen far to many little desks or chairs DESTROY a Revit model in both performance and presentation.

Go.. Download from RevitCity, SEEK, etc... Download from Herman Miller, and SteelCase....

But, I would highly recommend you take the time to at least understand how those models are built.

It is amazing how much has changed in 2 years....
I think you are right Revit Kid, but sometimes you models online can just be used for specific purposes, like Rendering, and they don't need to be a catch all. Example for these revit components: http://www.revitfurniture.com/
