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. nbv 2015-05-06 13:11 developer   ~0040613 Last edited: 2015-05-06 13:11 Dear Mikhail! Please confirm above said.
