Vid 11: Rectangle wrong plane and extra body

[FC-Architecter]

A question on the Fusion operation.

I do not know if it worked because the propellors are solid but the cylinder is transparent.

One thing I notice during the sweep operation is that it did not seem to be necessary to click "Sweep Path" to run the sweep. Would anyone know if this is why the cylinder is transparent and that I got extra helixes?

Also I seem to have 3 extra helixes.

You have transparency set to 50 in the view tab for the cylinder. Change it to 0, right-click and choose mark to recompute, then F5 to refresh. That should remove the transparency.

As TheMartkster wrote, you applied transparency to Cylinder before applying the Boolean Fuse. The Fusion keeps the colour and transparency of the original shapes. Another way to get rid of the transparency of the cylinder part of Fusion is to define a different colour than default grey.

Also I seem to have 3 extra helixes.

You don't. Those are the 3 helixes you created and used for the Sweeps. They are just not hidden automatically by the Sweeps. Contrary to PartDesign, some Part operations don't automatically hide the objects they are based on.

Now, you haven't completed the model. R-frank in his original video deletes the 2nd and 3rd sweeps and shows how to replicate them using Draft Array.

We seem to be having a bit of a tug-of-war about which video to use. Bejant's videos are better tutorials since Roland just does things without showing them and assumes the viewer is at a more advanced level.

In bejant's video, at minute 3:47, he sets cylinder transparency at 50%. He might have done something later to change this. No, I just checked. Somehow the cylinder goes opaque during the fusion. This was long before the boolean fusion. It might be good to finish bejant's. if this is even possible given the technological changes, then do Roland's.

Thanks.

FC_Architecter, can you please edit your next to last reply and fix your quote? You make it look like I wrote the whole reply, which you actually did.

I think I know why. Back when bejant made that video, the Fusion operation used to discard colour and transparency from its parent shapes. Later on, this was changed so the previously set colours and transparency would be kept in the resulting Fusion shape.

I just noticed this comment. Well before bejant's video, you only needed to select the path in the 3D view. Many users were confused by this, which is why a "Sweep Path" button was added to the Sweep parameters. I wasn't even aware that the old method still worked!

It looks like bejant's version of roland's propeller is completed, thanks to help from NormandC, Chrisb, and Markster.

Bejant goes back and resets the transparency of fusion to 50

He also moves some of the appearance settings from 3 to 1. Strangely, I followed him, but mine were set to 2.

Persistance is a virtue at times. Perhaps this is not one of those times.

I don't quite understand the reference of this comment.
Does this refer to the difference between the version the video tutorial and the present version of FC I am using (17)?

Ok, it was a snarky attempt at humor.

It was in reference to

and here we are again: These videos are made for 0.16 and as you should have learned from all the other video tutorials you have worked through: there was no body construct in 0.16.
All of Roland's videos are 0.16 videos. I guess allmost all video tutorials on youtube are made with 0.16 unless they state explicitely 0.17.

You have been told repeatedly, including a couple of times by me, that those old videos simply will not work the same way in FC versions 0.17 and beyond. And yet you continue to ask questions about why bodies appear in your models.
