- In the ToolSpace right click on Point Groups, then choose Export LandXML.
- Select the groups you want to export.
- Click OK to save the file.
Import Procedure:
- Click the Insert tab them LandXML to start the import.
- Select the file created above.
- Click OK to begin the import.
Now in the ToolSpace Point Groups section you should have the imported groups (along with any that existed before the import).
