On a faraway beach…

April 14, 2019

It has been a while since the last post but it had been very busy here at Livingroomcraftz. Which is good.

We got deeply involved with IFC lately, having the need to aggregate models coming fromm various different authoring applications into a common reference model. And that is where the Good, the Bad and the Ugly in IFC comes to the surface.

Challenge number one – working with large geo-coordinates. You take your Revit Model and add geo-referencing

All good – now you export to IFC with geo-coordinates on:

Noname

Still all good – now your IFC is geo-referenced

See here:

But what if you want to get a geo-referenced IFC back into Revit?

Lets try this now:

Noname

And the result:

An empty sea of nothingness – elements have been created but simply do not display

Noname

The reason for this is that – in a geo-referenced – IFC-file Revit will take the Survey Point coordinates as the Project Origin coordinates. Given Revit’s 24.5 or something coordinate limitation this is doomed to fail.

Alternatives? Let’s try the help of ArchiCAD:

Open the file in ArchiCAD

Using the bim6x plugin to ArchiCAD export directly to Revit

And the result in Revit is:

Getting there – life is good…
