[mcstas-users] Using Guide _anyshape

[Peter Link]

Hi,
I tried to use the Guide_anyshape component, and to start with I created 
a simple rectangular shaped guide element (i.e. 8 vertices and 4 faces, 
see nl2b.off below). The execution crashed with a Mem Error. The shape 
looks correct, if look at with an external off viewer...
Does anyone out there has already used this component, to give me hint 
what's wrong...
Best regards, Peter
