I am trying to develop a parametric Offshore platform for hydrodynamic analysis. For this I need a hollow surface model of the underwater hull surface. I need to develop the whole hull form through scripts only so I can use it in automated optimization problem.
This is how the mode looks so far.
I need to trim the square part to make a hole. I have the top surface (Surf_BaseOctagonUS) and the intersecting curve Part2_LowerCurve as objects.
Unfortunately I only have version 4, and since the academic license is not free, I must figure out a way to do this in version 4 only at this time.
As a quick fix, I am able to achieve the goal without using the trim function. I used the Rhino.AddPlanarSrf command with surrounding curves that enclose the hole. This gives:
However, later I may need to do similar thing with two intersecting pipes.
