Reply To: can someone help me better understand the differences of subdivide collapse and subdivide edges, and collapse edges, and when i would use one over the other?

Here’s what Subdivide Edges and Collapse Edges do:

The same stroke made with different settings.

Subdivide Collapse does both.

Subdivide Collapse is usually your best option, but when (‘famous’ use case) Pinching a Crease for instance, you will want to switch to Subdivide Edges.

I recommend playing with those settings for some time, while having the Wireframe (set to 1) Overlay enabled.
