Hi all,

I am completely stumped with this. I have read other peoples issues with LOFT on here and checked it against my model and still no joy

I have three sketches on 3 levels that I want to transition through. I have tried adding a few of the guide rails to test it but I’m getting model rejections. It seems to work sometimes but not others, but never with guide rails.

Can anyone point me to where my modelling is incorrect.

Sorry i cant post media at the moment as Im a new user…so:

After a whole afternoon of derbugging this I ended up solving it by breaking down the problem into chunks are adding additional levels to teh design rather than guide rails.

I guess the shape was too complex for Shapr3d to handle
