Sweep - solid edge - profile inversion

I attach a copy of the file with which I am having problems.

I have constructed an arcuate sweep with a triangular cross section.  I
need to form a layer (septre membrane} closely overlying two surfaces of the triangular
sweep (called a septre for these purposes).  To that end  I have formed
a sweep membrane template, a "V" shaped region at one end of the
sceptre.  When I seek to sweep the template along an arcuate edge of the
sceptre I get an inverted V shape, not at all what I require.  It does
not matter which edge I seek to sweep along I get the same inside out
shape every time.

I have tried deleting the built in folder to no avail.  I have otherwise
rebooted and updated the OS and "repaired" Turbocad.

I am running Windows 10 Pro version 1903 OS18362.476 on a Lenovo E540 with
Intel core i5 4200M CPU and 16Gb RAM.  Turbocad is pro platinum 2019 version 26 build 37.4

Is Attached what you want to achive ?
I did exlode your Acis so i could get the "circle" to follow, made a 3 pont circle and trim it, guess i could have used a 3 point arc aswell, moved the arc to M on the triangle and sweep work like a charm when i use the arc as a path.
You can use section tool also to get the profile, but i dont need the rest of the solid so … :)
Red is Path, Blue is membrane

I have noticed that the orientation of the swept object has an effect on the result.  Try selecting it and rotating it 90° in one of the axes before the sweeo to see how that changes your results.  You may have to undo and try with another axis.
