On the pictures below I’m trying to create the 90 degree sloping curves to a high degree of accuracy. The green lines indicate the slope, angle etc.
For whatever bizarre reason this is giving me a huge mental block, just this particular shape. I’ve also tried looking at the shape from different angles but I’m still unable to create it.
If the picture isn’t enough the curve is a rear part for a model of audio speaker, named “LS11”.
