this simple task will not sweep, it says unable to order.
I check with dir command and all are ok,
unlike where I found a profile that had to swing through 90 degs at its base and needed sweep1 rail whilst the rest needed sweep2rail, and which I realised the fault, this time that cause cannot be here.
There is no need for a separate sweep and joining the results together.
The shape I am making is the end of a split pin (cotterpin)
why then by selecting the dark purple as rail then the pinks as profiles in the order of the dir of the rail does this fail and say unable to order ?
