ComGraphix Data Exchange Format (CGDEF) Reader Parameters

This parameter will determine the reader's action when it comes across a symbol in the file.

If this box is checked, then the reader, rather than outputting a symbol feature, will look at the symbol definition for that symbol and output it as a series of individual features that make up the symbol.

Use this parameter to expose Format Attributes in Workbench when you create a workspace:

• In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
• In a non-dynamic scenario where you have multiple feature types, it is convenient to expose additional attributes using this one parameter. For example, if you have ten feature types and want to expose the same attribute in each one, it is easier to define it once than it is to set each feature type individually in the workspace.

Using the minimum and maximum x and y parameters, define a bounding box that will be used to filter the input features. Only features that intersect with the bounding box are returned.

If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.

When selected, this parameter removes any portions of imported features being read that are outside the Search Envelope.

The example below illustrates the results of the Search Envelope whenClip to Search Envelopeis not selected (set to No) and when it is selected (set to Yes).

• No: Any features that cross the search envelope boundary will be read, including the portion that lies outside of the boundary.
• Yes: Any features that cross the search envelope boundary will be clipped at the boundary, and only the portion that lies inside the boundary will be read. The underlying function for theClip to Search Envelopefunction is an intersection; however, whenClip to Search Envelopeis selected, a clipping operation is also performed in addition to the intersection.
