Boolean operation does not work with these objects - Why ? Or how would you do this ?

I am trying to figure out a method to Marc the seams on this curly mesh

I am trying to figure out a way to mark seams on this curly object. The ctrl click does not follow the edge it will only select one segment at time. This would take about 2 hrs to marc these seams. or even more.

The Select menu is your friend. Tools that can help you:

• Select Sharp Edges
• Select Linked -> Linked Flat Faces followed by Select Loops -> Select Boundary Loop

Selecting edge rings, then converting them to faces by ctrl+clicking the Face mode, then doing the “Select Boundary Loop” from above, also can work.

In side view and X-Ray/Wireframe modes, box selecting top or bottom vertices, followed by that same operation again, would also work.

Looking at that mesh, probably UV -> Smart UV Project, followed by some UV stitching and UV -> Seams from Islands, would save you the need to manually mark seams at all.

Select group of faces by angle?

Just trying to find out what the equivalent of this is in Blender; Coming from 3DS Max, there’s a checkbox you tick called “By Angle”, with an angle threshold value you can change, so that when you select a face, it automatically selects surrounding faces until the angle differs too greatly between polygons. This is great for selecting a “side” or “surface” of an object which is made up of lots of polygons. [Selection_100] [Selection_099] Example video here [3ds max Modeling Edit Pol…

Select face, Select similar (Shift+G ) > Co-planar or Normal and adjust threshold.

“Wow I wish I’d come back to check earlier. This is the ticket! Though I had to click around to find out how it works. Select a face, then at the top press the Select > Select Linked > Linked Flat Faces. Then at the bottom a little black popup appears with a dropdown arrow – click it and you have an angle you can adjust by clicking and dragging, or entering a value manually.”
