If you aren't seeing the dotted transition lines on your main gable truss, we have some tips to follow to get them to appear.
As you can see in the picture below, the blue dotted line shows the roof plane from the gable section connected.
If you're missing it, as this picture shows, we just need to make a small adjustment when adding the condition for the larger roof section.
In order for the software to see the connecting roof planes, you will need to ensure you're using the Auto Select Planes when adding the trusses for the A1 Condition shown below.
This ensures the transitional gable can see the connecting planes and will add the transition gable lines.
Please reach out if any further assistance is required.
