WN, Thank you so much for providing me with four different ways to do this.
I was able to obtain a solid using each method after watching the video.
It was a demonstration on a model that I could actually access, so it was more informative than any YouTube video!
I understand that Phiro's method is the second method, and BurrMan's method is the third method.
My mistake was to stubbornly try to create a solid under the zigzag solid. Only the fourth way is such an approach.
I also made the mistake of using "Edit | Join" to join each surface to get a solid.
I learned that the correct way was to use "Boolean | Join" as shown in the video.
I've been using MoI for about two years now (= my CAD experience). Dismantling the bottom of a solid to make it a joined surface and then adding other faces to create a new solid was a fresh approach for me.
I usually make simple models or models using Revolve, and I'm currently studying to make a cutter as part of my skill improvement.
This part is the grip of the cutter.
Thank you, Phiro and BurrMan. I was able to understand thanks to WN's video. :)
"""""""Hi, BurrMan. Is your method different from the approach Phiro suggested? Does "its base curve" refer to the red profile?"""""""
Yes. I finally got a chance to download your file and found a small anomoly in one of the original surfacves, so I made a quick vid of me fixing it, but I didnt get into depth. Just showing a quick fix when a solid had "Naked Edges"
The area at the "red profile" on your zig surface had a couple little sliver surfaces that prevented it from becoming a solid (You see it in the video)
As a quick fix I just deleted all those planar surfaces and ran Planar which replaced everything. If you started by running "sperate" and just deleting single surfaces, you will see the little sliver.
Anyway, just for you to view what I did to your model to generate the bottom half you were looking for...
Phiro, I see that I can create solids without "Boolean | Union" by using "Edit | Join"!
In Loft and Extrude, I had to join with "Boolean | Union", so is it possible to say that the surfaces are more well-formed, or "well behaved", compared to those?
BurrMan, Thank you. I had always wondered why some solids require a Union and others can be done with a Join.
This video has melted that question away.
The command used at 0:17 and 1:03 is "Highlight Naked Edges", correct?
If I want to get a solid and I get a Joind surface, I will actively use this command to investigate.
Hi MarzRX,
Yes, naked edges. I have it shortcuted so you didnt see me type it. Definitely a go to for “why not a solid”
Boolean vs Join
The way i would view it is boolean for solids, join for surfaces (that are edge to edge) if surfaces overlap in the middle somewhere, you would want to “trim” first.
Boolean is actually trim-join-remove rolled into one. So it “CAN” give results with surfaces, but just not the habit to create.
