As part of my Shapr3D learning journey, I decided to try to recreate some nontrivial shape from scratch. I randomly found a picture of some 3D object and started designing the model.  
But it seems like I either lack experience (in both Shapr3D and 3D modeling actually 🙂) or Shapr3D isn’t ready for that (yet?).  
I’ve attached both reference picture and my current state of the model. You can see that I stuck at “filling” the middle of the cloud. The challenge is to make the model **as smooth as possible**. All adjacent faces must be tangent to each other. You can see that the edges of the cloud are practically mathematically correct right now (am I going too hard?).  
The main issue I have is that I can’t make loft smooth whatever I do. g1 connectivity is successful very rare. g2 — simply never. Adding more tangent curves at the top and using them as guiding edges for internal lofts does not work almost always — all kinds of errors.  
Could you advise me on the approach I should try with this? It is for sure possible, that I need to start from scratch.

P.S. I can reproduce the shape in Blender relatively easy with metaballs and some vertex aligning and positioning, but I’d like to be able to recreate such a simple(?) shape in CAD-like software as well.

I would keep it simple by enlarging the spheres so they intersect and use fillet radius throughout. Here’s a Q&D approach. After all…it is a cloud.

For Blender users there is a cool add-on.

Blender to IGES. [Blender Add-on Export To IGES - #2 by pafurijaz - Released Scripts and Themes - Blender Artists Community](https://blenderartists.org/t/blender-add-on-export-to-iges/1324178/2)

It converts Subdivision surfaces to a 3d CAD format like IGES.
