This utility opens Bentley IFC Optimizer along with Select IFC File to compress / save compressed File Open dialog to select an IFC file to be optimized and saved. The IFC Optimizer will run several iterations until the default compression of less than 1%, however you can set a desired compression factor in the optimization.
SettingDescription
Iteration no. Displays the instantaneous status of the iteration in optimization.

The times -– elapsed, estimated left and compression size are flashed in respective fields. A tabular list of compression statistic is also displayed for each iteration.

Stop When Iteration Compression Less Than ___ % When the compression rate is less than the entered value, the IFC Optimizer stops.
Stop After This Iteration When clicked, the IFC Optimizer completes the current compression iteration, and then stops
Stop Now When clicked, the IFC Optimizer stops immediately at the current compression status.
The dialog also displays the status of compression in terms of size, percentage for each iteration and the estimate and elapsed times. Upon completion, a "Compression Finished" message prompts.
