Just another construction workflow with Dynamo - part 1

I'm back again with a simple construction workflow with Dynamo. In this first part I'll focus on element placement that I'll use in the second part, with help of Excel, to compare design with real site execution.
A professional way to conduct this site comparison is to use Autodesk Point Layout but, sometimes the job is easy and we can use Dynamo for this.

This time I'll use some screencast to show the workflow and I'll share all the DYN, RVT files used for this workflow.
First video shows how to create 3D grids useful to be exported in other software like Navisworks for visual checking. Actually navisworks already has a functionality to show grids from the models but simply this is a 3D double check.
At the same time, I'll place a family as a placeholder at each intersection of grids and I'll write in this family, the real coordinates based on the project base point.


In the second video I'll use almost the same workflow but, this time, I'll select elements from the model extract all the edges from the geometry and place points along the edges. Those points will be used to place again placeholders with coordinates information.
This workflow is perfect for site team that requires bottom of pipe coordinates, wall openings coordinates and so on.
This is he link to download Revit file (Revit 2015) and DYN definitions (Dynamo 1.2.1)

Enjoy and stay tuned for part 2!

Tunnel modeling with Dynamo

Introduction Last week I had a nice conversation with one of my Italian friends. The focus of the conversation was how to model a tunnel in Revit starting from an Excel list of points coming out from Civil 3D. So the answer was: Dynamo of course! First input, the section of the tunnel with his diameter; I can't share the details but lets say that we have: Theoretical excavation profile: 200 mm  Precast segment thickness: 500 mm Whit this two elements and the excel of the theoretical cent alignment, we can do everything! Revit profile family The first family we're going to create is a simple circle profile with a diameter parameter. This family will be as a mass category to be able to nest it later in an adaptive component family for the tunnel.  Just save this family...easy! Tunnel model Now we can create a new family as generic adaptive component and load the profile just created. It's important that the family is able to host rebars for future st...

Multi-pipe support configurator with Dynamo

As always everything is coming from my childhood…ops no, that's another story. As always everything starts on a white recycled paper just in front of my keyboard; a simple idea becomes immediately a sketch with Revit parameters. I tried many times different kind of plugins for automatic supports placement, but no one of these is able to create a multi-pipes supports (if I'm wrong, please let me know the name of the plugin). The idea for this script in Dynamo, is to create a support for a bounce of pipes going parallel for a while, and create a group that is possible to copy along the path. I'll not focus on the creation of the families that you need for the support but just to explain the main idea, I have 3 different pieces (steel bar, u-bolt and threaded rod) that I'll compose together to create the final support. The first challenge is to align the pipes to the same BOP (bottom of pipe) because they have to stand on the steel bar and locked with the ...

Dynamo, Revit, Excel, UI...what a wonderful day!

Introduction Today I'll show you two examples of how to use Dynamo to export existing Revit schedules and how to compose a custom schedule on the fly, to be exported to Excel. Both of them with a very nice graphical user interface thanks to Data-Shapes (https://data-shapes.net/) package. Export Schedules Let's start from the easier. The idea behind this script is to export a list of existing schedules to an Excel file, creating for each schedule a separate tab. To be able to complete this script you'll need two packages: Data-Shapes for the graphical interfaces BimorphNodes to extract schedules data The script is very easy and you have to focus only on how to create an interface Then you can use your input to feed the next nodes. Finished! So just push the run button (or use Dynamo Player is you are in Revit 2017.1 or 2017.2) and enjoy the interface. Export parameters to Excel In the second script I'll focus on something more int...
