Joining Surfaces

[pedrolopes]

Hello,
I am using Nastran FX.
Could anyone tell me what is the best way to join several surfaces so that each node of each surface mesh coincides with the other nodes in other surfaces?
I import the surfaces from Rhinoceros in a step file.
I have tried FUSE the geometry before meshing and after meshing it does look ok but the program usually crashes when i have more than 3 surfaces.
I tried repair geometry by matching face edges but when i do the mesh, only the first node, which is nearer the ends of the surfaces gets connected. The others do not.
The case can be for example a flat horizontal plate with a vertica plate at 90 degrees to it.
Thanks

Hello again,
I already worked this out thanks to the support team of SMARTCAE.
Apparently the problem was generated by the graphic card. I have a INTEL(R) G33/G31 Express Chipset family. I went to the properties of the graphic card and decreased the hardware acceleration to the minimum and it is working fine.
Thanks
