How to import IGES or DXF file into visual studio 2019(C++)

Hi guys, I am new to this software and I generated a cylindrical surface in rhino 7. Now I want to import it to visual studio where I can calculate normal vectors, tangential hectors and radii of curvatures. I am newbie in this area. please guide me!

Hi @Sai_Charannath_Dubba,

Since you are new, you might spend some time with the getting started guides and SDK samples.

Hi Dale,

Thanks for your guidance. I have created my first plugin by following those instructions.
There is a example of code given below. so my question is where should I write this code? (please see below pic)

In a .cpp file that is included in your project.
