Dynamo for design changes tracking

Just a simple workflow to compare two versions of the same model and understand what kind of changes we have:
- New elements
- Elements modified
- Elements deleted

With this release the script is only able to track where the change happened without any other detail but, I'm planning to make this more useful adding:
- Type of change (geometry, paraemter, etc.)
- Location of element deleted
- Selection of categories to be added to the snapshot (using UI++)
- Reports of changes

Inspiration came from this post:

but, of course, I would like to create something completely inside Dynamo!

For now just enjoy the idea!

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 …

Back to basic - How to setup a shared coordinate environment

This time I want to stop with very complicated dynamo scripts and workflows just because sometimes basics are important as well.
In this article I'll focus on the procedure to setup a common shared coordinate environment useful both as internal, if you manage multiple disciplines in your company, and external if you have to deal with consultants.
As always, I'll try to use as much as possible, screenshots from the software.

The first step is to create a new project with grids and levels. You can start from your template or just from a blank default template.
If you choose for the second option go directly to the "Site" view to be able to see the "Project Base Point". This will be the "Origin" of your project and the reference for all the other linked models. If you're not able to see this element, just open the Visibility Graphics window (VV) and make visible the element under "Site" category Now it's time to create grids and lev…
