  • To highlight multiple non-adjacent files, hold down the Ctrl key while you click on the file names.
  • To remove files from the selection list, highlight the file name(s) and click the < button or click the << button to remove all files from the selection list.

Click OK.

The following panel is then for each of the selected Geosoft files.

Include dummy values

Select this check box to read the dummy values into the Envisage layer. By default, Envisage will ignore the dummy values contained in the chosen Geosoft grid file. If this check box is selected, then you will need to specify the value that will be used to replace the dummy value.

Envisage layer name

Select the layer that will be used to store the imported points. The drop-down list contains the names of all layers found in the currently open design database. If you select an existing layer, then the resulting data will be appended to the nominated layer. If you enter the name of an existing layer that is not currently loaded, then you will need to confirm whether you want to load the layer or replace it, that is overwrite its contents.

To create a new layer, enter the layer name. The layer name:

  • May contain up to forty characters.

  • Must begin with an alphanumeric character [0-9] or [a-z].

  • Cannot include spaces.

  • Can include hyphens [ - ], plus signs [ + ], underscores [ _ ], periods/dots [ . ].

  • Can include the special characters of ÁÂÃÀÇÉÊÍÓÔÕÚÜÑ that are used in the Spanish and Portuguese languages.

Envisage layer description

Enter a description to further describe the contents of this layer. The description can be up to 80 alphanumeric characters and may include spaces. If a description is not entered, then a default description will be used instead. If the chosen layer already has an assigned description, the description displays when the layer is selected. Existing layer descriptions can be overwritten.

Click OK.
