ការប្រើប្រាស់
- The dialog states the scope plainly: extract one feature layer to a new feature class. For several layers at once, use Batch Export.
- Use attribute query enables the condition builder. Left unchecked, the whole layer — or the current selection — is extracted.
- The condition builder is the same as in Smart Select. Conditions are combined with And/Or, and each compares a Field using an Operator against either a typed Value or another Compare Field.
- Available operators:
Equals,Not Equals,Greater Than,Greater Or Equal,Less Than,Less Or Equal,Contains,Starts With,Ends With,Is Null,Is Not Null - Use selected features only restricts the extraction to the current map selection. It combines with the attribute query — the result is the features that are both selected and match the conditions.
- Select applies the query as a map selection so it can be checked before extracting. Use it: it is much quicker to correct a condition than to delete an unwanted output.
- Output Location and Output Feature Class Name set where the result is written.
