How to draw coil fin heater

May I know how to draw this coil fin??

You can't attach a link back to your own computer.
I suggest that you attach an image directly...

Basic answer will be, draw the profile and use follow me, then array if needed.

What version of SketchUp are you really using? You put 2018 Make in your profile but that doesn't exist. Knowing which version you are using will make it easier for us to give you good direction. One thing is for sure, if you model the fins on that with geometry, it's going to slow your computer down. It would probably be better to use a texture.

How will you use this thing once you have it modeled, anyway?

Thanks for your reply. Actually I'm using an online version from this website.

I'm new at SketchUp, may I know what's mean geometry and texture?

Geometry is edges and faces. Textures are images that you apply to surfaces. Since you are using the free online version you will be limited as far as what you can do. No extensions so you would have to model it manually. I would suggest not worrying about modeling the fins and just make a smooth tube using Follow Me. Then apply a gray color or a metal texture to it. For your hobby application that should get the job done.

Here's a quick example drawn in SketchUp Free.

A path for Follow Me
Add a circle at the end.
Run Follow Me.
Extend the ends with smaller diameter circles and add a metal texture.
