Revolved shape in STEP file is imported inverted

[elias-bananaz]

Description

The attached file is imported incorrectly. It appears as if the revolved shape is imported with the complementary angles instead.

Expected Behavior

Shape should look like this:

Actual Behavior

It looks like this instead:

Sample Code or DRAW Tcl Script

# read STEP file into XDE document using STEPCAFControl_Reader
jsupload /models/occ/as1-oc-214.stp
ReadStep D as1-oc-214.stp

# display the document in 3D viewer using XCAFPrs_AISObject
vinit View1
XDisplay -dispMode 1 D -explore

7.6.3 it was correct. 7.7.0 - already broken.
Regression. But unfortunately, can't be done for 7.9.0. Will be planned for the next release

[elias-bananaz]

Thanks. Can it be fixed at least in the development branch?

[dpasukhi]

Yes, if the fix will be ready, it will be available in dev

I have another file that has a problem with a revolved surface. Not sure if it's the same problem, but I'm sharing here nonetheless.

Blades lock.zip

You can see a sort of "blemish" at the center of the shape, when the surface is triangulated.
