Summary	0020465: Wrong checkshape results for shells.
Description	In accordance with specifications: A shell is just set of faces. Nevertheless, the class BRepCheck_Analyzer performs checking any quite independent shells as if they are parts of a solid. Corresponding DRAW command "checkshape" produces following errors for a shells: BRepCheck_InvalidMultiConnexity BRepCheck_BadOrientationOfSubshape BRepCheck_CheckFail On the other hand if to try to create a compound of faces (which the shell consists of), this compound will be valid. Use the following commands to reproduce the bug: restore r checkshape r explode r f compound r_1 r_2 r_3 r_4 r_5 r_6 r_7 r_8 r_9 r_10 r_11 q checkshape q
