Modeling a Pendentive Conceptural Mass

[Anonymous]

Hello, 

I am a student working on a Mosque project that incorporates a dome. I was attempting to model pendentives supporting each corner of the dome but have been struggling to create the desired form in the conceptual mass environment. I am able to create the curved triangular shape I want to achieve but the mass is split into four separate areas that are very prominent when attaching walls by face. I have attached my conceptual mass family and screenshots to assist any understanding.    Thank you for any help you can provide.

Try a 4-edge form and cut it with voids.  Below shows 3 voids but you can just use one void to cut it in half right at the diagonal.

Can you post a photograph of a structure that that resembles what you are describing?

Sure, I am looking to create the portion under the dome in this photo.

I would use Masses for this. Then you can apply Walls to Mass Faces. 

...something like this? It's a quickie.

This is close to the solution I ended up using to achieve the result. I ended up making a square mass and used a spherical void to create the face I wanted without it splitting into multiple faces. Thank you for the critical ideas.

Yeah, I guess you could do it the hard way.  I had a better suggestion, but I guess I'll save it for another since you already closed out this thread.
