Hi,
I am trying to insert an edge loop at the point marked by the big red arrow. Notice that the edges have been selected. I am trying to use the Insert Edge Loop Tool but under no circumstances can I get the loop to be inserted. I can get the very same process to work using a polygonal cylinder but not this object.:headbang:

Btw, to select the edges I am using a convoluted process of marking two edges then converting them to edge loops, and then I convert the selected edge loops to a vertices selection then convert that selection to edges then shrink that selection once. This works but there must be a better way. Obviously I'm very new at this so it would be nice if anyone has any tips on how to improve this process and how to insert the edge loop.

Thank you,
Ron
