How to make this kinda o-grid?
 
Hello guys, I am trying to build a room model. Till now i have been using square openings but im now supposed to use circular openings and thus i have to use 0-grids now. I have been advised to use a specific sort of o-grid. The picture of which is shown below. I want to create the same sort of o-grid for my model but cant seem to create it in that manner. Can you please help me by telling me exactly how to create the following type of o-grid structure? Thanks.

These are the views of the blocks without the mesh enabled of the kind of 0-grid i should use.

I dont know what im doing wrong. If i tick the "around block" in the split block>o-grid block panel i dont get the round kinda mesh around the openings. Rather the blocks around the openings are distorted in another fashion. Help me please :)

You mean associating the rectangular edges to the circular curves of the openings? Nope have not done that buddy.... is that what im doing wrong? :confused:

Yes you need to make the appropriate associations and I see that your model has three concentric circles so you may want to have three o grids all together to make a proper capture
