[LDCad] Problem exporting model to ldd

[Moe]

Got it! Well, everything looks OK on the LDraw side—looks like you've solved the submodel issue. So it must be something with LDD; and since the grid looks fine, I'm guessing it is just that the parts are missing from LDD.

Just in some cursory web searching, I see there are issues with EV3 parts, specifically, being absent from more recent versions of LDD (here's one example). The workaround, unfortunately, seems to be to try and find an older install that you can revert to, or just switch altogether to a program that's still actively developed.

Yes, I did solve the sub model issue, thanks to you all and your super fast response. And yes LDD 4.12 has an issue with EV3 support so I had to downgrade to version 4.11 which has EV3 support. I guess I'm gonna have to talk to my professor about submitting the ldr file as is.
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?
