Why loft doesn’t work on these two identical profiles? Sharp3d v.25.142
Hi,
Please select Tools / Loft, and in the tool the two faces, it should work. Let us know if it doesn’t.
I did select those two profile but loft command inactive…
We are aware that the Loft is missing from the Selection based menu, that’s why I suggested entering the Loft tool first, and then selecting the two faces 
Same result
I then draw others profiles on those two profiles, loft works, how do I know what wrong with those two profiles?

Hi Gusriwandi!
Loft doesn’t work on profiles with openings.
Please try Loft with solid profiles and then use Shell tool to create the opening inside the body.

Thank you, I export it to Fusion360., doesn’t work either, I think something wrong with profiles
In some cases there might be geometry inside the model that would be affected by closing the body up before lofting and re-shelling.
In that case, I would do it this way instead…

And here’s a quick and dirty method…
Creating a ‘notch’ allows lofting to be performed because there are no longer any openings in the profile. Simply close any gaps up after lofting.

I had hoped to be able to delete the gap but I kept getting an error message:
“The face can’t be deleted because the resulting hole in the body can’t be filled”
In any case, the ‘quick and dirty’ method I used is a great cheat… right?
Here’s another solution.
Split the profile then loft, mirror, union…
