||Re: Convert CAD Annotation to point shapefile
||Jul 07, 2008
||If you're trying to associate the attributes in an annotation feature class to the polygon features that they overlap, you can create a spatial join.
You can do this in the layer properties by adding a join and selecting create a join based on spatial location or using the ArcToolbox Analysis Tools/Overlay->spatial join tool.
You can also use the Spatial Adjustment Toolbar-> Attribute Mapping tool to map fields from one feature to another by configuring the options to match fields from a source layer field to a target layer field.
If your join is based on a attribute field, you should be able to join from an annotation layer.
To convert to a point file, you can try the ArcToolbox Data Management Tools/Features->Features to Point tool (Must have ArcInfo to use this tool).
If not, I know the following will work:
1. Add a double type field to your annotation layer table to store the X centroid location for each feature
2. Add another double type field for the Y centroid location of each feature
3. Right click the X centroid field that you created in the table view and select CALCULATE GEOMETRY and set the PROPERTY to X coordinate of centroid and then select OK to populate the field
4. Repeat step #3 for the Y centroid field selecting the Y coordinate of centroid property this time
5. Open the layer's table and select Options->Export and save your table.
6. Select the ADD XY DATA tool from the TOOLS menu and set the X FIELD to the X centroid field and the Y FIELD to the Y centroid field
7. There should be a new layer added to the map. You may have to make it permanent or export it to a new feature class/shapefile.
