I am trying to import IGES data using IGESControl_Reader.
The problem is that it may take 5 minutes or more to load IGES data of 3MB.
Please let me know if there is a setting to speed up the import of IGES data.
I've already tried the following:
- importing only visible entities by IGESControl_Reader::SetReadVisible(true)
- changing value of parameter "read.precision.val"
