The third and final article about BIM and Revit in landscape architecture is now up on World Landscape Architecture:
—
As a landscape architect, I am sometimes asked by architects ‘Why do you use Revit?’ And the answer is quite simple: for all of the same reasons that architects and building engineers do. This may seem obvious to anyone familiar with the program and its capabilities, but to the uninitiated this explanation is not sufficient.
So to more clearly explain the benefits of using Revit, I created this diagram which outlines seven main points as they relate to several larger, overarching concepts: information, automation, and collaboration. Most of these benefits overlap in various ways and can also be found in other BIM software, so it is worth noting that they are not necessarily unique to Revit.

Hi, Lauren:
it’s a long time to see your new post here!
I have a question about your article on WLA. I found that a GIF picture in the midden part of the article which is a section with a element of tree family. It seems like that there is a root ball. Can you explain that how to add the root ball in the tree family.
Thank you!
I mentioned at the end of this post, https://landarchbim.com/2015/01/15/scaleable-landscape-families/ how you can nest a rootball family. But if you’re interested, I could also do a more detailed post and even include a Revit family for download.
Thank you for your reply and I really want to study more about the root ball family in Revit. To calculate the volume of root ball which with different size of plants is an important work in most of public construction cases in Taiwan. Could you provide more details about plant and root ball ? I think that many people will interested here or how control the family instance with Dynamo.
Thank you very much.
