break surface using plane from 'node-dependant system'

Altair Forum User

I am creating a model using thin shell surfaces for a ship-type structure where the side slopes outwards from the bottom. I would like to be able to cut the side stiffeners on a plane normal to the sloping side, not parallel to the global axes. I have created an axis system with the Z axis normal to the side, but use of this system seems to be very inconsistent in Hypermesh v13. I can create a surface by extruding a line in the local Z direction, but I can't create a line by extruding a node. I can't create nodes using coordinates along the local system. I can't break a surface on any plane except one of the global planes. I have done what I want by creating a vector then a line then a surface and breaking self-intersecting surfaces, but it is very long-winded. It would be so much easier if I could break the surface using local planes at a given base node! Any chance of Hypermesh adding a local system option to the edit - surface - plane form?

Hi RobinMM,

 

I have created an RFE to include such option in future.

Thank you, that is good to hear. I look forward to seeing the result in due course.
