Can we change the order of the columns in the Defaults setting of a report?
It is not possible to change the order of the columns within Defaults.
You can change the order of the columns after you export to available CSV formats by opening this in Microsoft Excel and changing the order as per your requirement.
All the report templates are available in the INSTLIB folder of the ArtiosCAD version you are working, with a file type .XSL. Example: autocoldesignlistcsv.xsl. Anyone who has knowledge of XML/ XSLTI can customize to your needs or Esko Professional Services can customize these reports and would be payable services.
