problem in loft between a circle and hexagon
You do not need guide curve if you solidly work with surfaces !
-
Step 1:
Before sweeping, creating a flat surface with the hexagon along the circle. This will give the opportunity to sweep tangeance with the circle.
-
Step 2:
Use boundary surface hexagonal before circle and put it normal to the surface
-
Step 3:
You can choose the circle profile and put it tangeant to the surface
-
Step 4:
Now you need to knit all surfaces and "try to make a volume" with them. See my SW 2015 file.
