Why are my planimetrics not being displayed when I toggle on Survey>View Survey Data Planimetrics?
A likely reason for planimetrics not being displayed is that the styles associated with the planimetrics do no have a recognized named symbology. Check Tools>Style Manager. If any of the named symbology names are displayed in red, they are not being recognized. To correct this problem, either create a named symbology by that name or change the named symbology for that style to one that is recognized.
