Let's change the transparency of the wrs2descending layer to be able to see both layers at the same time. The problem seem to be solved if you use Fix Geometries tool in QGIS. What is Arc doing differently, and is it necessary?. Gmsh is built around four modules: geometry, mesh, solver and post-processing. For more information on the OGC's definition of geometry simplicity and validity, refer to "Ensuring OpenGIS compliancy of geometries". After a feature's geometry is repaired using the OGC option, any subsequent edit or modification may cause the geometry to no longer comply with the OGC specification. There are two metal studs at the sides. Knowing which tools to use and how to apply them is essential to. Upon discovery of a geometry problem, a relevant fix will be applied, and a one line description will be printed identifying the feature as well as the problem encountered.
