surface now will not go through all section curves 1

[G1DESIGN]

My next problem if i may ask for more help

Problem

i am trying to create a simple wing shape actual its a foil for a boat.
i set up a plane, on this plane i have two planar sketches to form two boundary edges
i set up section planes at 500 mm (7 in total) intervals and on each i sketch an aerofoil shape of the min section number at the tip (plane 1) to max aerofoil shape on plane number 6
it then tapers back to a slimmer foil section on plane 7

go to boundary blend

i pick the boundary curves on top plane as my 2 of my boundaries then from plane 1 to 7 pick the section curves
sections 1 and 7 form the loop with the two planar boundary curves

this is when my problem begins the surface goes through all the curves from 1 to 6 but when i pick curve 7 it seems to disconnect itself from curve 6 and flow under the section not taking it into account this section curve im not sure how to fix this as everything i try doesnt seem to work

hopefully someone can help me here

Have you tried adjusting the Control Points in the boundary blend? Pro/E uses these control points to determine which curve segments to create surfaces between. Sometimes if the control points are backwards, the resulting surface looks twisted and knotted. (The Control Points tab is in the Boundary Blend feature dashboard)

Also, maybe a swept blend might work better. I haven't made one in a while, and I can't remember whether or not it is possible to select multiple trajectories in this feature. If not, you may be able to do it by splitting the section curves and creating two swept blends, and finally merging them.

hope it works out

tried control points to get result and they seem fine hoever it just wont quite attach to the curve, it looks like a graphics problem but when measured chord length to width its incorrect at section 6 and correct at the others meaning the geometry is wrong.

swept blend only allows me one guide curve at the leading edge and wont allow me to guide the trailing edge(my experience is limited of sweptblends is limited)

thanks for taking the time to answer much appreciated.

how far off? Maybe you should use a smaller number of accuracy?. You could try doing it with a blend between each section with boundry contraints.

"i pick the boundary curves on top plane as my 2 of my boundaries then from plane 1 to 7 pick the section curves.
sections 1 and 7 form the loop with the two planar boundary curves"

Are sections 2-6 not connected to the 2 boundary curves?

If not, the curves in between should be influencing curves, so they do not actually pass through the section, rather, they "pull" the surface towards them.

So, try to make your surface with the 2 boundary curves in 1 direction, and curves 1 and 7 in the other. Then under the "Options" tab in the Boundary Blend feature, assign curves 2-6 as Influencing curves. Then, lower the Smoothness Factor until you get an acceptable result.

It won't be *exact*, but it should yield something closer to what you want.

Hope this works better...
