I can make an ellipsoid with two different axes with the rotate tool but how can I make an ellipsoid with 3 different axes?  
Thank you

We (a bunch of us renegades) are hoping for scaling independence. As in ANY direction… x, y or z and not limited to JUST x & y & Z. 😝

😂😂😂  
It was a real question 😉  
The only solution I found is by using the loft tool (but not very precise):

That’s what I’m trying to do

How did you draw this shape, can you show a few more pictures from other angles as I have a project to do that I think could use the same principles, any help would be appreciated

Hi  
I want to make a human heart with the left ventricle (bi-axial ellipsoïd: easy) and the right ventricle (tri-axial ellipsoid).

I had to bild my ellipsoid slice by slice:

 ![IMG_0252](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/2X/2/2b1d402cee0b8cf5a5ca7a6d5c5d8f9c0570426b.jpeg)

with a tiny disk on the top of the ellipsoid:

 ![IMG_0253](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/2X/6/68f221393d856964c1236600e3c653447b186a26.jpeg)

then use the loft tool:

 ![IMG_0254](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/2X/5/54217243e2d300589313fbcc0d9927ca6122a942.jpeg)

the top isn’t very clean and make the shell tool impossible, so I had to hide the top of the right ventricle by making a rotation:

 ![IMG_0243](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/2X/6/63052558814264089af6d987a0e159fe744ff60a.jpeg)

and then substract, shell and union tools:

 ![IMG_0245](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/2X/9/93b440d9dff986682eb5b6ea1b792106c26df5b3.jpeg)  
 ![IMG_0246](https://us1.discourse-cdn.com/flex002/uploads/shapr3d/original/2X/0/002ea770f1cd42ce79f8aa0ef9b016b964d2ce70.jpeg)

I made disappear the inner wall of the right ventricle by giving a negative value to the offset face tool:

and finally union and chamfer:

Thank you for taking time to show me this Michael, I shall try this approach soon. Strange yours is a part for a heart, mine is to create a part for a model aircraft…

The solution worked for me thanks to the community and the members for the solution.
