+Currently BLSURF plugin has the following limitations.
+<ul>
+<li>Mesh contains inverted elements, if it is based on shape, consisting of more than one face (box, cone, torus...) and if the option "Allow Quadrangles (Test)" was checked before computation.</li>
+
+<li>SIGFPE exception is raised at trying to compute mesh, based on box, with checked option "Patch independent".</l>
+
+<li>It has been found out that BLSURF algorithm can't be used as a local algorithm (on sub-meshes) and as a provider of low-level mesh for some 3D algorithms because BLSURF mesher (and consequently plugin) does not provide information on node parameters on edges (U) and faces (U,V). For example the following combinations of algorithms are impossible:
+<ul>
+<li> global MEFISTO or Quadrangle(mapping) + local BLSURF;</li>
+<li> BLSUFR + Projection 2D from faces meshed by BLSURF;</li>
+<li> local BLSURF + Extrusion 3D;
+</ul>
