How to do 3D blocking for such a geometry
 
1 Attachment(s)
I have been trying out different possible ways of blocking to follow the geometry. could anyone suggest me with any ideas ?

two methods
 
Method 1:

Follow the 2d pipe junction and also see this video : https://vimeo.com/86772893


Method 2:

create one block for the larger pipe and make splits at the junction. Now create block from four vertices

@ Far .. Why is it to hard to move vertices for a 3d blocking when compared to 2d planar block. I assume due to the dimensions of the geometry. Is there any other way to move the vertices freely for a 3d block

I have uploaded the tin file. I am unable to create the block using the 4 vertices. Could you once have a look

Here is the blocking for your geometry.

Hallo Far,

I have gone through your blocking. Could you explain me how did you manage to get so many points on the circles .

With the help of edge mesh parameters
