(I think I’ve gone insane…) Another 90íes song title that come to mind but summarized beautifully the finding of the day.
Think coordinates – long ones. Think about geo-referencing your Revit file. Think about angles and coordinate precision.
Allow me to take you onto a ride – we start simple. In Revit we rig up a simple test bed such as this:
That’s the project units – now lets set up the project:
Basic – lets just add a dimension to the angle:
Now – to make it a bit of a challenge – let us apply shared coordinates to this:
And now let’s check the output after exporting it to DWG:
So far all looks good – here is a close-up measured in AutoCAD
Now let’s change those shared coordinates to something mildly insane – but Chinese Xi’an 80 system has insane long numbers:
Now lets see the result in AutoCAD:
If you look at the coordinates in AutoCAD you might see the difference

And for now – life is good…
