About regression in "bugs moddata_3(014) bug23471".

Test is BAD on the current MASTER (IR-2015-04-23). Try the following script to prove:

Draw[]> restore [locate_data_file OCC22790-cx.brep] b
Draw[]> explode b
Draw[]> mksurface s1 b_1
Draw[]> mksurface s2 b_3

Draw[]> viso c1v s1 0
Draw[]> uiso c1u s1 0

Draw[]> viso c2v s2 0
Draw[]> uiso c2u s2 0

Draw[]> bounds c1v u1 u2
#u1 = 0 u2 = 74350.7519540878

Draw[]> xdistcc c1v c2u u1 u2 100
#Max distance = 3.96773050108729e-012

Draw[]> bounds c2v u1 u2
#u1 = 0 u2 = 24095.0965554287

Draw[]> xdistcc c2v c1u u1 u2 100
#Max distance = 0

I.e. single intersection line must cover two iso-lines: U=0 and V=0 in the s1 surface AND U=0 and V=0 in the s2 surface. Nevertheless, it does not on the MASTER. Fix in CR25890 is not the reason of this problem.

CONCLUSION:
1. This test should be market by "TODO" and must be fixed later (in bug 0026190).
2. There are two bugs related to this: bug 0026190 and 0026191.

Dear Mikhail!

Please confirm above said.

Test bugs moddata_3(014) bug23471 has been amended (improved) - see attached file "bug23471". It must be added to the branch and retested.

Dear Mikhail,

Branch CR25890_1 differs from CR25890 only bug23471 test case.

Therefore, there is no point in testing CR25890_1. Or you can add this script in the branch CR25890 without any testing.
