[LDCad] Problem exporting model to ldd

[N. W. Perry]

One more question:
                               How do you unwind the connection cables in LDCad?
                               And how do you connect them to the EV3 ports, sensors and motors?

I don't know how you'd do it in LDD, honestly. But in LDCad that's a job for flexible parts, which you'll find in the Templates group in the part bin. For how to use them, they're introduced here (scroll down to "Dynamic Parts"; electric cables work the same way as the pneumatic hoses), and there are handy videos on YouTube.

If you could use Studio rather than LDD, the LDCad flexible parts can definitely be exported over to that program.
