Merging two topologies using subdivision surfaces

In this tutorial, we return to the use of subdivision surfaces to blende two different topologies.

loved it, thank you!

I've been binge watching your tutorials and picked up a lot. the PCBL (Planar Curve Boundary Loops) approach is a revelation! Two things I noticed: - the subdivision surface modifier has, in advanced, Boundary smooth > keep corners. - often, when you use the cursor to scale a group of vertices from the cursor, you can also use the active selected vertex in the group, use Transform Pivot point > Active Element to scale from that selected active vertex. I think that is a few less clicks :)

This is a topology class!!! Thanks

I'm started with Blender in October and thanks to great tutorials like these I getting the hang of it. I really appreciate the time and effort you've made creating these in depth tutorials, thanks 👍

Thank you very much for enlightening tutorials. As you mentioned a couple of times there is other ways, however it's great to see fundamential basics explained properly and with proper pace. Great job.

Use crease at absolute 1 for protect boundary is clever! (Normally I only use crease below 1 for edges to control smooth by subdivision)

Thank you!

0:06 one thing i didn't understand is how you're gonna merge both meshes the slate and this mesh cause slat curvy area has more vertex than this there will be shading issues i guess. i need to know this thing i must. but on other hand i am loving the whole series this little thing if you make understand i will be thankfull

I'm not sure I understand what you're asking to be honest.

I don't get why you use this method for 12 min. to create the middle part. You duplicated the loop from the side mesh already, why not delete every second of the curve verts (between the boundary verts) that is to much (or rebevel /decimate the segments count) and then extrude it to the middle parts size. Then you can continue to cut the circle. That would save you at least 11min., if I didn't get it wrong what you tried to archive / show here!?

First, thank you for such high-level content. Now, regarding the video, yes, it is good to know the tool, but it is a hassle anyway. Polygon modeling is suitable for low poly, organic and retopology, but this is a NURBS task. Period. Suppose you have to iterate over the finished model or try different variations. It is just not possible. If the bevel was too strong, nothing to do. If you need to boolean a piece in an advance state of the modeling, good luck with that. If you get more complex with the forms and the intricacy of the details, it will take you forever. If you miss a detail, then you have to redo everything. So, no thanks. Blender is not the best for it.
