This step of creating a rule set helps you to map feature types to the features in your ASCII file. Additionally, you can assign the field names to the delimited columns.
Feature Type - Select the check box(es) of the feature type(s) that are to be imported. All of the available feature types are provided in the Feature Type list.
To map the feature type name:
If a feature type exists in your ASCII file, highlight the line in the Feature type area.
Click in the list box under the heading "In ASCII file" on the same highlighted line.
Type the feature type name exactly as it appears in the ASCII file in the edit box.
If there are multiple feature types in the ASCII file, but a feature type name is not defined in the file, the parser doesn't have a way to differentiate which feature is a point, circle, and so forth. However, if there is only one feature type in the ASCII file, you don't need to define the feature type name. You only need to mark the check box to the left of the feature type.
Feature Fields - The available fields for the selected Feature Type are displayed for assignment. Each field represents a valid PC-DMIS value for the selected feature type.
To assign a feature fields to the columns of the ASCII file:
Select a Feature Type.
Select the needed field name(s) from the Field List. To select consecutive fields, click the first item, press and hold down SHIFT, and then click the last item. To select nonconsecutive fields, press and hold down CTRL, and then click each item.
Click Add to add the field name to the list box on the right.
You may also ADD or REMOVE fields by double-clicking the item in the Field List or the list box on the right.
Use the UP and DOWN arrows to ensure that the field values appear in the order that the corresponding values appear in the ASCII file.
Select any unneeded field(s) from the list on the right and click Remove to remove that field name(s). To select consecutive fields, click the first item, press and hold down SHIFT, and then click the last item. To select nonconsecutive fields, press and hold down CTRL, and then click each item.
PC-DMIS may not accept certain fields in the ASCII file that may be proprietary to a third-party CMM system provider's software. For such a field, the user can add the field called "Skip" to inform the GP to skip the column that contains this field.
