Converting Points

In this exercise, you’ll convert Land Desktop point objects into Civil 3D points and export the data to LandXML and ASCII format files:

1. Open the 0302_ConvertPoints.dwg or (0302_ConvertPoints_METRIC.dwg) file.
2. Use the List command or the AutoCAD Properties palette to confirm that most of the objects in this drawing are AECC_POINTs, which are points from Land Desktop.
3. On the Home tab ➢ Create Ground Data panel ➢ Points menu, select Convert Land Desktop Points.
   Note that the Convert Autodesk Land Desktop Points dialog allows you to choose point-creation settings and styles.
4. Place a check mark next to Add Points To Point Group.
5. Click the Create A New Point Group icon.
6. Name the group Converted From LDT, as shown in "Figure 1 (Converting Points from Non–Civil 3D Sources)", and click OK.
7. Clear the Preserve Original Point Layers check box.
   This option will move the resulting points to the layer specified in the description key set if there is a match. If there is no match, the point will go to the default layer.
8. Click OK to complete the conversion process.
   Civil 3D scans the drawing looking for Land Desktop point objects.
9. Once Civil 3D has finished the conversion, zoom in on any of the former Land Desktop points.
   The points should now show as COGO points in the AutoCAD Properties palette, confirming that the conversion has taken place. The Land Desktop points have been replaced with Civil 3D points, and the original Land Desktop points are no longer in the drawing.
10. In Toolspace ➢ Prospector tab, expand the Point Groups category.
    Notice that there is a yellow exclamation shield symbol indicating that the Converted From LDT point group needs to be updated.
11. Right-click Point Groups and select Update.
12. On update, the points will display using the defined settings.
13. Select the Converted From LDT point group, right-click it, and select Export Points from the menu.
14. Now do the following:
    1. Set the export format to PNEZD (Comma Delimited).
    2. Define the destination file as a text file.
    3. Name it 0302_ConvertPoints.txt or (0302_ConvertPoints_METRIC.txt).
    4. Click Open.
    By default the selection of points is limited to the selected group.
15. Clear the advanced options check marks if any are selected and click OK.
16. Select the Converted From LDT point group once more and right-click it.
17. From the context menu, select the Export LandXML option found toward the bottom of the menu.
    In the dialog box, by default your point group is selected to be exported.
18. Just click OK.
    You will be prompted to save the LandXML file, and the suggested name should be fine.
19. Save the file.
20. Once the export is done, save the drawing file.
