What is the right approach to fill a tapered volume?

[Anonymous]

If I just extrude the green slice, it pokes out of the exterior of the shape. I'd like to extrude in the direction shown by the dimension, filling up the space between the sketch plane and the closest geometry. 

What's the best way to go about this?

I think I figured it out. Instead of trying to go out from the inside face, I used a loft from the left to the right.

Another way - Replace Face (see Attached).

I've never used that feature before! It took me a while to even find it on the ribbon. But it works! Thank you very much.

The loft command can be patterned, but the Replace Face one cannot, is that right? My intent is to make a 5X pattern for the feature I'm making.

[JDMather]

That is correct.

Hi! There is another approach using Surface Modeling workflows. You don't need to create any sketch actually. Simply use Offset/Thicken command to create a zero offset surface from the inside faces (bottom). Then use Sculpt command and select XZ plane, Workplane2, and the offset surface to create the new solid body. After that you can pattern it as a feature or as a body.

Many thanks!
