Default Cylinders and subdividing

Running into a problem. Subdividing a cylinder is causing it to warp too much. I tried placing edge loops near the end caps, but they are also causing a distortion. I want the cylinders to remain straight, but just smooth out more when I subdivide.

Un-weld the end-cap surfaces.

I'm confused.... exactly what are you trying to do?

Sorry Stig, I'm trying to do this, so obviously I got it to work.

I'm still curious. Why would you want to "subdivide" a cylinder, rather than simply create it from the get-go with the number of sides you intend? Is it to be subdivided along it's length or the number of faces around its axis?

And what is the end result you want to achieve? If it's what I suspect (wanting segments of varying circumference along one cylinder), I have a suggestion to get the effect you want with a minimum of trouble.

Yes, the "point" you see is intended to look like blown or dripped glass. I didn't want hard angles making it look like it was made with a CAD.

As I've said, I'm probably not doing things right.

Right now, I've put that little project aside, since there isn't much remaining on it, and picked up crafting a sword. Small, little things to get familiar with best practices. Making the sword is also giving me problems with edge loops squeezing polys when subdividing. I'm going with your idea of making it with simple, unsubdivided polys. It's turning out well. I'm about to move on to texturing, which has always been a difficult grasp for me.

Debating adding a fuller.

Consider "latheing" it. That way, you need only draw a Line of the profile on the 0 Z axis, then use Object > Revolve... to complete it. And to make it smoother, you can increase the Crease angle, so that no hard edges appear on the surface.
