Hi! Could you please look at my design attached? I can't understand why I'm getting here shown in the screenshot vertices out of the planes a little bit according to the XYZ measurements. Also if you look at some closer you'll see here are at right 2 vertices (near start measuring point "1").
It happens after the fillet command is applied. I've rolled back the timeline and checked each step and can't find the reason for it. Where have I made a mistake?
Thanks!
There is no "destruction" of geometry 😉
The geometry is quite a reasonable result of your modeling approach, with is distinctly different in at least one key aspect, from what I demonstrated in the earlier key cap design we worked on. I'll demonstrate that later, possibly in a screencast.
Hello @summerson1990
This is a very strange issue. I tried to trace back the steps as well and I found an issue just after offset surface feature as shown in the following image. Now, I don't know whether it has any effect on the final result though. I will forward this to the development team so that they can investigate it further.
We will update once we find some reason or the solution to this issue.
The additional vertices and edges in the design of the keycap, highlighted in red
Are a result of 2 things:
1. Sketch #3 defines tangency between the arcs and the line. That is also exactly where the tangency edges in yur base-key cap appear:
And those will then also appear in the fillets. They have to for the geometry to maintain integrity.
2. You are lofting between a planar and a curved profile. In my key-cap version I lofted between 2 planar (but not parallel) profiles, which results in a much cleaner loft. Then I trimmed out the curved top of the keycap.
I also would recommend you keep the fillet on the top edge separate form the variable fillet.
Then you can make it a chord fillet to get a better visual result. This might not matter for a keycap due to it's small size, but it doesn't hurt either 😉

You do that, while I recommend a better design workflow, which completely avoids the issue 😉
Thank you @TrippyLighting 🙂
I believe the given workflow should have worked. I hope the solution makes our tools more robust.
Here's a screen recording that explains why these extra tangency edges appear and why I think there is no bug to be discovered and nothing to be made more robust. The HD versions are still converting as I post this:
