I am in process for making 4 ecodomes in india. I am done with markings and layout plans even i have arranged earth bags, barb wire and other things. I am using idea of Bonita homes, but I have a query about placing the bags. The radius I kept is about 7 feet and I wish that to be 15-18 feet tall for main dome and 10 feet for smaller domes. I am searching how to make that dome shape. How much to adjust the row inside in each lane to get that dome shape (like first 5 feet in straight then sliding bags 1-2 inches inside ? ). Any help from experts ? Please find attachments.

Hi Waqar -
We used the information in this book: https://www.amazon.com/Earthbag-Building-Tricks-Techniques-Natural/dp/0865715076 when we built our single 16' inner diameter scoria bag dome. It is about as tall as it is wide. We had a rope on a centered pivot point, and changed the length of the rope with each new level. The rope stretched so our rows were not perfect, but it still worked. Next time, I would use a chain. I do not know how to help you with the shape of domes you are building, but I thought I'd pass along what worked for us. Good luck to you.
dream green homes is a god source. Use a piece of wire for your measuring line. Same with X bracing - using cable (much like rope) will not really do it, you need solid material so it doesn't stretch (learned the hard way).
Hi, the attached drawing is an explanation of the technique used at Cal Earth for controlling the interior shape of a dome. the center compass sweeps the radius and the guide chain is used to adjust the length of the compass each time one lap or course is completed.
Things recompose in compost and we live in a food web.

Thank you all for help. I have almost completed a dome with other on the way. I wish to know how to get that plastered from outer and inner surface as I think the cement plaster wont stick directly on bags. Please assist.
