Cross section lines are not matching at the control points. Bottom slab is tapering in plan and web is tapering in elevation. I tried sweep and loft with different settings but seems to be not working.

only 3 sections of the profile / shape change.
my recommendation would be to build a polyline with 3 segments, do the loft, fillet the edge.
also check the overall precision in the corners:
there is a deviation with around 0.3 mm…
so you will come up with something like this:
(3 surfaces - black)
(1 base - red)
(curvaturegraph showing issues … a nice surface does not necessarily need many CV’s / shape curves, less is more)
use filletEdge or if you have to fullfill the input sections precisely ExtrudeCrvAlongCrv to build the missing part - or loft the arcs as well… make sure to check continuity.
what s the data / geometry for ?
if this is a 53 meter long concrete building that will be build - i am happy to help you to get proper geometry.
kind regards - tom
this is the “right” way to do this job- ^^
much more control of the individual surfaces than trying to loft all in one go-
Hi Tom,
My final goal is to create shell analysis model for this geometry. I have created the geometry based on the centreline of the cross section.
As I try to mesh the geometry, I am facing issues with the nodal connectivity at the solid diaphragm versus shell deck elements.
Let me know if you have any suggestions.

Thanks!
make sure the Brep-Join went well.
Bake and analyse with _showedges
do not directly use Brep → Quadremesh
but do a defined meshing inbetween.
maybe even weld / triangulate or other optimisations before Quadremesh.
check the options of quadremesh:
