I have encountered a serious flaw in the software. The problem is how LandXML files are imported and exported. I have a drawing that is set to US Survey feet in the Units and Zone settings. I have assumed that when I export data to LandXML format, the exported file would be set to US Survey feet. However this is not the case. There are settings for LandXML Import/Export that I was not aware of. These settings will override the settings of the drawing if there is a mismatch. There is no warning to the user that the exported file will not match the drawing. This has resulted in construction staking being shifted with obviously devastating consequences.
The software should at least give a warning if there is a mismatch. A better solution is to include the units options in the Import Export dialog rather than having them in a separate dialog.
