Acute3D Mesh Referencing Incorrectly0 in Microstation V8

I'm trying to reference a 3mx file into Microstation. The mesh comes in with Easting and Northing both too large by a factor of 3.281...

Living in North Carolina, I am using the GCS NAD83 EPSG:2264. This GCS is in USft. My microstation drawing and my ContextCapture product are both in this GCS.

I've verified my control points' accuracy in Acute3D viewer and they're spot on. I've imported the ascii file with my ContextCapture GCPs and they are coming in at the correct location.

Why is my mesh referencing in at such an interesting scale factor? (1m=3.281ft)

  • Since the conversion between meters and US ft is 3.2808333... you won't do any better than "pretty close" using 3.2808 given the order of magnitude of your coordinates.  I haven't worked with 3mx files so I don't know what formats the scale factor can use, but the preference would be a factor of 1200:3927 which is the definition of a US ft.  If you can only enter a real number use 3.28083333..., with as many 3s as you can enter in the field.
