sheetmetal wall to funny angle - rectangular transition

[t2b]

This is hard to explain- please bear with me.

I have drawn a frame work for a sheet metal hopper with the top & bottom open, with a rectangular section at the top, sloping middle section and rectangular bottom section.

This is how:

1. create a plane on the middle trapezoidal section & create an 'unattached flat wall'

2. add 'flat wall' to top & bottom - this works ok I can modify the placement/shape/sketch and use the 'create an entity from an edge'button to tie the sketch to the original frame. ( the final stage is to alter the frame dimensions and recreate sheet metal flat pattens for any hopper size).

3. the bad bit.
trying to add a flange to sloping side of the trapezium;
using the add flat wall, placement/shape/sketch and use the 'create an entity from an edge' button- I can create the wall but cannot tie in the angle to the frame work which i want to use to drive future configurations. i can get by for a 1 off using this but i have to measure the angle then manually input the angle into the shape tab.
I have tried using the add flange wall, which works for edges where there is a square plane to reference the flange angle, but with the edge of the trapezium being at a 'funny' angle the sketch doesn't work out.

thankyou for reading this far.

A picture of the part would help. Have you tried add a flange wall using all the edges rather than a flat wall?

thanks John- I might be trying this the wrong way- I'm thinking it could be an open parallel flange- which i still need to cover the tutorial.

Rather than making a small flange wall on the sloping side of the trapezium, make a full wall like the one opposite, and then cut it back to produce the flange.
