SolidBuilder

Surface and simple solid features

Solid features

This port outputs surface features that were not used in creating closed solids.

Also, when there is a set of geometrically identical solids, all but one of these solids will be rejected. Two solids are considered geometrically identical if their geometries match exactly. Non-geometry properties like coordinate systems, measures, traits, and geometry names are not considered when matching input geometries.

Non-surface or non-solid features

Leaving this parameter blank causes the entire set of input solids to form a single group. Alternatively, this parameter allows you to select attributes on which to form groups of solid features – each set of features that have the same value for all of these attributes will be processed independently in a group.

No attributes other than Group By attributes will be carried across from the Input features to the output features.

Note: How parallel processing works with FME: see About Parallel Processing for detailed information.

This parameter determines whether or not the transformer should perform the work across parallel processes. If it is enabled, a process will be launched for each group specified by the Group By parameter.

Parallel Processing Levels

For example, on a quad-core machine, minimal parallelism will result in two simultaneous FME processes. Extreme parallelism on an 8-core machine would result in 16 simultaneous processes.

You can experiment with this feature and view the information in the Windows Task Manager and the Workbench Log window.

Yes: This transformer will process input groups in order. Changes on the value of the Group By parameter on the input stream will trigger batch processing on the currently accumulating group. This will improve overall speed if groups are large/complex, but could cause undesired behavior if input groups are not truly ordered.

No: This is the default behavior. Processing will only occur in this transformer once all input is present.

If a list name is specified, all attributes of all input features that created the outer shell of this solid will be output here.

Note: List attributes are not accessible from the output schema in Workbench unless they are first processed using a transformer that operates on them, such as ListExploder or ListConcatenator. All list attribute transformers are displayed in the Contents pane of the Transformer Help under Lists. Alternatively, AttributeExposer can be used.

The Drop Voids parameter indicates whether or not solid features used to cut voids in containing features should be dropped or output.

This parameter will be added to each output feature and will contain "yes" if that feature was used to cut a void inside some other feature, and "no" if that feature did not cut into any other features.

If a List Name and a Void List Name are specified, all attributes of all features that participated in creating the voids of this solid are stored here.

Note: List attributes are not accessible from the output schema in Workbench unless they are first processed using a transformer that operates on them, such as ListExploder or ListConcatenator. All list attribute transformers are displayed in the Contents pane of the Transformer Help under Lists. Alternatively, AttributeExposer can be used.
