Multiple tapers

The best way to arch a component would be to use subtractive modelling.

So you would draw the part out at its largest rectangular dimensions.

Then draw on tape lines to give yourself reference points

Use the arch tool to give you the arch and 'bulge' you want

Then do an extruded cut to subtract the bits of the model you don't want.

For multiple tapers It depends on the version you've got. If you've got pro then make 'cutting blocks' and use the move and rotate tools to orient them how you want them. Once they are where you need them then use the trim or subtract solid modelling tool to get rid of the geometry you don't want.

If you have got the free version then you have to make sure that you haven't made anything you want to modify a component and then pick single edges and use the move tool to manipulate them. The sticky geometry function of sketch up will pull the surrounding geometry around with it.

I hope that helps and I have understood your question properly!

Here's the way I approach tapers:

  Set a shape with the straight (before tapering) dimensions.

  On the end to be smaller, set guide lines for the taper dimensions.

  With the move tool, pull each top edge to the guide lines.

  Remove the guides.

 

There are all sorts of ways to do it. 

This way is fast, simple and easy.
