Convert to T-Splines creates strange look

[kreatronik]

Hello,

So I have this extruded body where I want to shiftthe top face to the middle of the hole and the rest of the body adopts.
Therefore I wanted to convert it into a form but with this result of the top face having this overhanging "roof":

Any ideas what's going on? Or did I use the "Convert" tool in a wrong way?

Thanks
Hannes

Btw. around the hole will be 4 of these items. The function is a clamping, that the foot can't fall out of a metal sheet, when a screw is threaded into the foot.

Hi,

There is no need to use the form tool.

Hi, 

first of all at this case when use convert all faces should has equal divide (see the photo ) 
then I want to use "weld vertices" tool for join all faces together (to become as one single geometry)  with check  " keep creases "  
then I use" fill hole " tool , check keep creases with collapse

No, I mean not "tilting the top face" 😅
I want to shift it parallel to the base of the foot that it moves closer to the middle of the hole. When I put a screw through the hole, then it will push these 4 pieces outwards.

Hi, can you please make a screencast of your tool usage?
I don't get it, especially the welding doesn't work, as I can't (don't know how to) select the correct objects.
As this fails, of course, I can't use the "Fill Hole" tool.
I looked for a hint searching the internet, and wasn't successful. How did you learn these steps?

Sure , watch This

Hi,

something like this?

Hm I'm still struggling.
Here in Fusion and in your screencast I noticed, that using the selection frame in welding actually doesn't select anything after you release the mouse button.
Only when I click on single vertices, then it also shows them as selected. But there is no chain selection of several.
Please check back. Also I saw, that the top contour was already welded after the converting.

I check everything there is no any wrong 
follow my steps at the screencast and make a screencast to see what you do "

note  : "using the selection frame in welding actually doesn't select anything after you release the mouse button." ..
it selected all vertices but not showing so "just press OK " and (don't) select  single vertices . 
top contour was already welded  because  when I welded all faces that allow me to use fill hole and no need wild tool here .

and don't forget to check "keep creases " active

No, I need the overhang from the beginning of the hole.

I finally made a loft with another profile on an offset plane.

Unfortunately, you have not presented it that way so far.

This is also possible without Formtool.

I see virtually no reason to us T-Splines for this whatsoever!

Thank you for this idea with the sweep.
I also found out that for the clamping to work, I need it like in my solution, because when the screw is in, the little pegs have to bend outwards beyond their footprint on the bottom .
