Ray,
Not familiar with TurboCad, but make sure that when you save it as a dxf file that the complete content is exported. Other CAD
programs allow you to turn off layers / levels / whatever such that they are not exported.
In LC you should see both of the connecting rods if exported correctly.
I suggest you have a read of the LazyCam Manual. When generating code within LC you need to have the layer enabled.
Read the manual.......
If you want post the "version 12" dxf for someone to try it on their end.
