At first made the body from a rectangular with the extrude tool.
Angeled the sides with move/rotate tool(pull the vario to the edges)
Made the plane with “cunstrucion plane tool” (perpendictual Edge at point)
Draw the section, on it and use the sweep tool to make the hip-rafter
The another rafter was drawn ,
By construction plane : trough the at angle
Draw the section, and also use the seep tool to make the rafter.
Then use the move/ rotate tool( use the copy).
With the “split body” tool made the exact rafters ( select the body , select the another rafter sides), delet the longar part.
May be use vid slow, and can be seen also
