Small but Painful Naked Edge

Greetings Rhino community, you’re favourite n00b here!

I was trying to complete one of my old project that i never managed to finish and i stumbled upon this stupid edge that doesn’t match with the other one by a couple of microns.
I was planning in doing a nice 2 rail sweep between the two borders to get a nice fillet but no, this little vertex is sticking out of the border just enough to make the 2 rail sweep comand fail.

Is there a way to fix this without rebuilding the entire surface again?

select the lower vertice holding Ctrl+Shift

then move it to the top vertice

you will also need to fix this,

at the opposing edge

plus the surfaces are 1.06° tangent difference


The vertical surfaces don’t meet with the necessary continuity. To fix that, follow the steps below. The last one is very important:

  1. Use “Split” with the “Isocurve” option to split one of the surfaces. In this case I split the right one.
  2. Build two blend curves top and bottom via the “Adjustable curve blend” tool.
  3. Use “Sweep 2 rails” to create a blend surface in-between (with the “Tangent” option).
  4. Open a nice beer and drink it. :slight_smile:

How did you managed to get that specific on that 1.06 tangent difference?

I alredy knew about the Ctrl+Shift shortcut for the gumball but didn’t know you can also select vertices.

Very nice, Thank you so much

And for finding this did you use some other command or you found it just by looking around?

since I could not merge edges at that point, I investigated it
