Creating existing trees from loci

Loci with tree survey data, which may have come from a survey file, imported DXF/DWG file, or point-based shapefile, can be converted to existing tree objects with the proper attached information, including location. By mapping the attached data to the existing tree record fields, valid existing tree objects are created in the Vectorworks Landmark file.

Parameter	Description
Saved Settings Options	See Using saved sets to save and apply saved settings
Survey Data
Use Attached Record	Select a record attached to the loci to map to existing tree parameters; when deselected, the existing tree objects are created with the default values of the Existing Tree tool, and no mapping is possible
Preserve Record in new Existing Trees	Attaches the selected record to the created existing tree objects, so that all record data is preserved
Record Mapping table	Each row in the table corresponds to a row in the selected record
Field Name	Lists the record field names
Parameter	For each row, indicates the existing tree parameter that the Field Name item is mapped to
Unit	For each row, indicates the unit that will be used during mapping. ● If the imported row contains text or entries which do not need a unit, leave the default selection of None/Automatic. ● If data can be mapped with the specified document units, this will occur automatically with the selection of None/Automatic. ● If the imported data requires units that are different from the document defaults, select the unit to use for importing the data.
Field Type	Displays the type of record field, for informational purposes
Selected Existing Tree Parameter	Indicates how the selected row data should be mapped to its equivalent parameter at import
Selected Unit	Indicates the units for the selected row at import

3. If using a record attached to loci as the basis of the existing tree parameters, select the record, and then select each row of the record mapping table. Specify how each row should be mapped to the equivalent existing tree parameter by selecting it from the Selected Existing Tree Parameter. If necessary, select the specific units that should be used if they are different from the document defaults.

When mapping to existing tree parameters, the associated data values are mapped directly when the type is compatible. For example, when the height parameters are mapped, the height value from the record becomes the Height value for the existing tree; a mapped Condition parameter is set as expected if the entry matches one of the default options (Excellent, Good, Average, Poor), or to Custom if the entry does not match the defaults.

If no data are provided for mapped parameters, the default values of the Existing Tree tool are used.
