Description

All of the geometric entities imported from the attached STEP file are incorrectly located, shifted down approximately 99.8 mm along the Z axis.

This is a regression from 7.4.0.

Steps to reproduce

Enter the following commands into DRAW:

pload ALL
StepRead D "Test1.stp"
XGetShape S D 0:1:1:1
bounding S -shape BB
XShow D
vdisplay BB

Results differ significantly between 7.4 and 7.5 DRAW per attached screenshots.

OCCT 7.5.0 has added a new STEP import parameter "read.step.root.transformation" and handles some - could you please check if changing the option moves shape back?

OCCT now takes AXIS2_PLACEMENT_3D entity into account for transforming roots in the document, which, however, might be not always expected behavior.
