It is not currently possible to edit the object properties (line width, line color, polygon fill patterns, etc) of a vector file (BLN, DXF, GSB, GSI, MIF, SHP, etc.) directly inside of Voxler. When a vector file is imported into Voxler, it is converted to IV file format, where the properties are static and not editable. As a work around, Surfer or Didger can be used to edit the properties of the objects contained in a vector file and then the file can be exported to DXF format. The DXF format will retain all of the custom property changes for the objects when the file is exported from Surfer or Didger. All of the properties, excluding line width and fill patterns, will be retained when importing the DXF into Voxler. To export a customized base map from Didger 5 that contains the object customizations you can use the following steps: Now that a DXF file has been created with the desired customizations, it can be imported into Voxler by using the File | Import command. In the Import dialog, navigate to the DXF and click Open. The DXF file should import into Voxler and should display the objects with the customizations added in Didger or Surfer. Thanks very much for your wonderful products I have used for all these many years…(I started over 25 years ago when I was at the Univ. of Idaho, I had one of the early copies of Surfer, etc.) Nancy B.
