My land XML data is the surface data from the same project.
Hi Martin
LandXML is a BIM format whereas DWG is a generic CAD format. The problem is the CAD file is loose in its definition of scale. In our opinion this is a major weakness of DWG and DXF. Probably the core problem here is that either :
- The units of the CAD file are being 'guessed wrong'.
- The LandXML and CAD file are in different co-ordinate systems
- There is some issue with International Feet and US Survey Feet.
Why is Kubla 'guessing CAD units'
CAD files do not contain a 'units setting' there are various things that can be used to try to guess what the likely units are (e.g block scaling units) but it is not reliable. We have improved this code a lot in Kubla Cubed 2024 but the fundamental issue remains.
If you send the files to support we can let you know what the problem is. It might be that it is fixed in Kubla Cubed 2024 which is due for release this week.
