Great tutorial, although I couldn’t do the FilletEdge of 0.1cm like image 47. I tried everything but it didn’t workout…

About the boolean union problem, just put the section (“little triangle”) on the start of the spiral burt and a move a little bit inside, to the interior (make sure your middle point is not over the end of the line) . You will get a very tiny intersection between the bulb surface and the spiral which will enable the boolean union…

yes, you are right. Image 44 shows filleted curve, and the move image (img45) doesn’t. If you look at the img46 you will see that one has filleted corner. It is just an error in the image.
But I understand you are having problems, maybe that wasn’t explained the best way, but basically you need to have your section filleted curve positioned perpendicular to the spiral, and with trial and error you should position the curve so when you do sweep1 command you get the surface right. Meaning, it goes through the surface bottom “cap” so you can do boolean union without problems.
I might record a video of this step, it might get a bit clearer. But the important thing is you need to do this by trial and error.

I am having the same problem with the boolean union, it just fails. There is a step I really don’t get and is precisely in the image 44, before that you had a triangle with filleted edge and after that there’s no filleted edge

go see image 44-move. You could try extending the two ends of the V curve, and moving it a bit more like on the image. That should fix it.
if you still have problems, please post your image and/or model in the forums under this tutorial and I will help you more.

i am having difficulties making a union between the sweeped coil for the threading and the body. do you know why that is?
i just get the message ‘boolean union failed.’

[...] this tutorial, naturally, you will need a model of a bulb. So, you should first read and complete Modeling light bulb tutorial and create yourself a model. Oh, you’ve done it already? No you actually just took [...]
