hy
sorry for late.
i used both of them Rhinomarine and Orca3d . it will be better for you to understand the differences betwn them if u use their demo .
I got nearly same hydrostatics result that i get using rhinomarine and Hydromax calculation. but i get many difference in result for orca 3d.
Rhinomarine gives you two types of output. as *html and Excel sheet format. in the excel sheet, it will produce Values with corresponding excel graph . And every curve is in different worksheet ..
moreover, i found rhinomarine is easier to use and user friendly.
thanks
