Hi,
Is it possible to fix the seam in the corner here as it will not allow me to create a fillet. It's an issue I run across for time to time & would love to know if there is a work around ?
Maybe at the beginning of your modeling rotate the sphere for have the seam in a place where there will nothing till the end...
In your special case seems your object is symmetrical and you had successed to make a fillet on the same piece on the other side so...
Just Mirror your result! ;)
So you can grab and separate that piece out. select all the edges and do a join to get curves (Left in your file)
Select all the edges and hit delete to recover a sphere... rotate the speres seam edge away fro your work, then trim with the curves you grabbed.
Hi flippyfloop attached here is another version with the seam rotated like Burr's.
My method is Edit > Separate on the sphere face. Do an "untrim" by selecting one edge of it, then Ctrl+A for select all then Delete. Then Transform > Rotate > Rotate axis to rotate the sphere, then Edit > Trim and use the "Select naked edges" shortcut key (http://moi3d.com/forum/index.php?webtag=MOI&msg=6051.2) in the step where you are selecting cutting objects. Then Edit > Join to glue it back together.
