Import same step generated different shape, it looks like the shape is rotated. Compare with OCC6.8 VS OCC7.6

check the step model in the SPUJ190900.7z
Check in other cad softwares, they show the same result as in 6.8, Is it a regression issue?

This behavior change in STEP translator is related to processing of transformation assigned to a root element. The old behavior could be requested via "read.step.root.transformation" parameter:

pload XDE VISUALIZATION
param read.step.root.transformation 0
ReadStep D SPUJ190900.step
vinit View1
XDisplay D -dispMode 1
vtop
vfit

Thanks for the quick reply. I got the same result after I set read.step.root.transformation to 1 in occ7.5, in Occ7.6 you should set to 0
BTW, that parameter is not in the documentation.

How to change the "read.step.root.transformation" parameter?

Interface_Static::SetIVal("read.step.root.transformation", 1);
