Trying to draw an elliptical cone

Is there an elegant workaround without using a plugin?
It depends on what version of SketchUp are you using. Please complete your forum profile with that information.

Smoove has a falloff that could achieve such a result...
Here's a very basic example.

Ok

Really no way to do this natively in Sketchup?
Rich showed you a native way to do it.
Another non-extension way to do it would be to stitch the vertices together with the 2-point Arc and Line tools.
The method I showed in that thread of using Follow Me and then scaling the large end to make an ellipse doesn't require any extensions.

Ok

Smoove is a tool under Sandbox
Falloff is a linear decline in influence over distance

Ok

I see

Thank you
-
- Draw the primitive divided circle
- Scale from centre along an axis
- Select the boundary edges and active Smoove. Set a value for your falloff
- Position geometry and shade smooth
I can't give you precise values as I didn't do it to any particular size. So you may have experiment with your falloff values using Smoove.

Ok

Too many straws.

Ok

it's a profile using an elliptical shape with follow me. all native tools.
if you're trying to duplicate the HF drive on the speaker in your first post - Genelec uses a mathematical model to generate it, not drawing tools. when i model their speakers for recording studio designs, i use the profile and elliptical curve or the scaling method - which ever one looks "close enough" since i'm not actually making the speaker, just need it for size and rendering purposes.

Ok

Follow me on an ellipse will not produce the shape you want.

Ok

But I thought I'd try an elliptical horn rather than round. I had no idea I was opening a new can of worms
The worm is the native only approach. Since SU is primarily a conceptual design tool and you require some level of accuracy its supported via extensibility.
The core can't do it but it can be done.
