To accurately display your data, our system will need to know which coordinate system was used in its design. For DWG (Vector) sources, you will need to enter coordinate system's EPSG code before synchronizing the data source. To set the coordinate system, enter the appropriate EPSG code into the Coordinate System field found at the root level.
EPSG stands for European Petroleum Survey Group (https://epsg.io/) - an organization that maintains a geodetic parameter database with standard code for global coordinate systems, assigning a unique number to each of them.
Normally, your designer should be able to provide this code. If not, a quick google search with the name of your coordinate system and the word EPSG should provide you with the code. I.e. "California state plane zone 6 EPSG"
