How to create organic shapes in Sketchup

Hi, I’m trying to make a pipe (the one you use for smoking) and i was given the shape, but i have no idea how to make it. I’ve watched some tutorials on yt to try to understand more about this program, but I’m having a hard time finding a solution. Can anyone help me?
The attached file contains the form I need to follow.

The method I use for organic shapes is low poly quadface modeling and then apply a subdivision surface. It’s not something for beginners but is the best way to model with a good mesh, you need plug-ins to do it, personally I use Quadface tools, vertex tools and subD from ThomThom. Watch on YouTube quadface modeling on sketchup.

i tried to install it but i dont see it. I downloaded it and added as extension, but I don’t get the options to work, that is, it says it’s added but I can’t use it

Did you also download and install TT_lib2?
