If a DWG reference file is created with imperial settings, it will import to Tekla Structures in too large scale. You can use this advanced option to prevent this.

If you want all coordinates to be meters, set this advanced option to TRUE.If you want to take the unit from the DWG file based on the measurement and $insunit definitions in the file header, leave the value out. By default, this advanced option is not set to any value.
