- Add checking for null object for edge_curve within TranslateEdgeLoop;
- Update STEP parser rule allowing empty element in the list of entity parameters;
- Update test case of bug26451 for a new scanner rule;
- Update test case of bug30273 for a new added check for null object
Changes made for #31233 are reverted.
Correction in the ShapeFix_ComposeShell:
Modification of the method SplitByLine in order to find all points of the intersection for case when initial curve shifts in the positive or negative direction
to avoid splitting edge when split point lies in the limits of the tolerance of the vertex.
to correct shift of the pcurves for case when initial shift is more than 1 in the method ShapeFix_ComposeShell::SplitByLine
In the method ShapeFix_Face::FixMissingSeam added removing small edges having length less than working precision and removing wires having area less than working precision
Modified test cases; added test for related issue: bugs step bug31301
Now end points of intervals calculated in GeomAdapter_Curve are not replaced by GeomAdapter_Surface.
Left bound of periodic curve less than UMin is not corrupted by LocateParameter during intervals calculating.
