Split Entities not trully Split

Can someon tell me plese when I use the split entity tool on a circle,
and split it in halfe, when I clique on each halfe it selects in two
halfes all right, but yet when I try to surface extrude it then it
extrudes as one entity. How do I get the circle to extrude halfe at a
time, if you can help me. I need to add a tangent curvd line later on
and need to add tangents relations is why I need to split circle in
halfe.
I thank you for helping me

In most cases what you are talking about is actually a benefit. There is
automatic functionality taking care of this in the background. Years ago
it used to do as you say, but they made it smarter. If you want to have
a cylinder split, it is probably best to use a Split Line feature using
a plane to split or using silhouette edges to split.

You can add tangent relations without having a split point. You can also
add tangent relations to the sketch instead of the edge, which is more
stable anyway.

 

Good point. As an example that you may expect, you will note that if
you extrude a contour with two, connected, collinear lines, those two
lines only make a single planar face.
