Right click on the view and select align view vertical or horizontal then click on the edge of the view you want either horizontal or vertical.

Dimensions in Onshape drawings are measuring 2D projections of the object as it sits on the paper, rather than the "true" dimension of the 3D object.

So you will not be able to have dimensions on your ISO view, because it will only be a "Point-to-Point" dimension as if you printed out the paper and measured those points with a caliper.

When creating the helix, use the "height and turns", "height and pitch", or "turns and pitch" options instead of the "turns" or "pitch" options. You'll be prompted to select a circular edge instead of a cylindrical surface. The helix will start at that edge and have the same diameter. But the height/pitch/turns can then be entered manually.

Drawings as s Single Sheet or Multiple sheets might seem trivial but is a big question I have asked myself and on different Onshape projects, at the moment you can't change your mind 1/2 way down the track so is important to get it right up front. I have chosen both ways on depending on the project. It is, however, an issue at the moment that singles can't be merged to a multiple page drawing or vice-versa down the track you want to change the setup. @MichaelThiesmeyer I'll vote for that IR.

Why is this an issue?
For me, a multiple page drawing becomes more compact in the Onshape doc (minor thing but 100 tabs are hard to handle) and is easy to print/export, I really like structuring my drawings this way, I can have 100 pages in the drawing, RMB on the tab to export and I have them all in 1 PDF in a few seconds. However, I normally do single sheet drawings based on the part number because if you want to add links to specific drawings from elsewhere that seems to make more sense.

@PeteYodisI am really looking forward to more ways to copy, move and edit my drawings, the more time I can save the better. I also too, regularly want to move an already detailed view to a new sheet.

The white dot versus the black dot:
White dot is a sketched "Point"
while the black dots are "End points" or "Center points" of other sketch geometry. In this case, the black dot was the center point of the ellipse, and the white dot was a sketched point that was placed on top of the circle's center point. (I just deleted this point by window selecting and  deleting in sketch 16, as it was not being used)

You had a Plane 13 defined as an offset from the front plane.
This will not be as accurate as Plane-Point. because of tolerances.

once you fix that,
then make sure you are following the "path" instead of "guides and continuity"
also add some section counts to help smooth out the loft

I actually worked on one for that too. It's here. To give credit where it's due, I started by copying one by @NeilCooke
 (yet again) and modifying it only a tiny bit. Check his out here. I'd eventually like to find a way to toggle each field between a string or an equation, but for now, the prefix and suffix are strings and the segments are type "Any" meaning they can do calculations. It can also assign the part number if that's useful.

No, you are doing it right. Properties are config-specific so you do have to align all the stars. A wilcard option would be good.

@Evan_Reese 's FS could be easily extended to allow face colors.

You are looking for the 'wrap' feature.

I actually made that update a few days ago. It works with faces now.
