sweeping in VB

Hi,

I am having trouble lofting with a VB component. I have two curves that need to be lofted but the result is a segmented surface (not ideal for offsetting). Typically if I do this manually, my workaround has been to sweep with 2 rails and a cross-section. Now I am trying to achieve this with the VB components but not know really where to begin. Are there any precedents for this thus far? I have attached the gh file for reference which has three lists; rail 1, rail 2, and cross-section- and then want to plug them into a script, any help or place to begin would be great!


Thanks
