Practical ideas for Revit, BIM and construction technology. Built from years of shared experience.
Changing and updating Shared Coordinates in Revit can be quite a challenge. At Virtual Built Technology we often create a Revit Control File to manage and transfer project datums, shared coordinates a…
I’m sure you are aware that intellectually Revit shared coordinates take minutes to explain, but emotionally they take years to master 🙂 I’ve been looking for a way to check and validate coordinates u…
At the moment, Revit communicates using its internal zero point when importing or exporting IFC. You can read this LinkedIn post where Joris Van Bossche describes his findings: You can also read my pr…
Revit doesn’t like big numbers. There, I said it. So when dealing with ‘world’ coordinates in a point cloud, sometimes things just don’t work too well. I thought I had this all solved recently by usin…
When Revit exports to IFC, it typically uses the current Location (Survey Point) Shared Coordinates as Origin. You can observe this in the IFC file: But what if you want to Export to IFC with Project …
I thought that most of this was ‘easy’ and solved now, but it was more of a challenge than I expected. I received a ASC file from a survey in XYZRGB format, which looks like this: Those XYZ values are…
Let’s face it, sometimes Shared Coordinates can be a pain. Issues may arise when trying to make small adjustments to very large numbers, and that comes up in other places in Revit too. In some cases, …
Video: Matthew Miller recently gave high praise to this class, when he posted that David Baldacchino’s class AB412 Navigating Through the Storm Using Coordinate Systems in Revit “has been the best exp…
When exporting to IFC, you may find that Revit feeds the Survey Coordinates (or shared coordinates) to the resulting IFC file, when in fact you want it to be based on Project Coordinates. If your proj…
