Summary0024024: Slow import of specific STEP data
DescriptionImport of attached STEP file is performed very slowly. Scene is quite simple, but sample program "Import Export" (supplied in OCCT installation package) loads this file during 15 minutes (on Core2Duo 2.66GHz). Import using OCCT API also takes similar time.

Is it possible to speed-up the loading of such scenes by OCCT? May be some workaround exists?

Problem is not reproduced on current state of master. Branch CR24024 (contains testing case) was created.

Testing case:

 Version 6.7.0 (where this seems should be fixed already) imports this file with almost the same speed: in 6.6.0 import time is 14:50, in 6.7.0 it is 14:00. Is it eventually possible to speed up it?

 Import time of slow_import.stp in ImportExport MFC SAMPLE is 11-12 minutes (AMD Athlon II X4 630 2.80 GHz).

But loading this file on OCCT 6.7.0 import time is 5 or 6 minutes (test case bugs step bug24024).

Add bounding boxes to accelerate import, now it is nearly 1 minute.

Branch CR24024 is ready to be reviewed.
Dear GKA,
Please review.
