Thank you for your post.
I've uploaded an example roof (which you can downloaded) similar to the image you sent across. I used degrees in my model but the principles will still be the same. If this is the result you were after, below is how I got it. I will be referring to the image I attached throughout it.
I made the white, grey and yellow sections of the roof into one roof. The white and yellow sections were raised higher then the grey section and the yellow section gable side was extended past the fascia (I extended it 100mm but you can use whatever length you want) and then added all the gables and different pitches around the roof using the Edit Roof Pitch Tool.
I then manually edited the yellow section to line it back up so that the fascias of the white and yellow sections lined up by pushing the gable back the distance I extended it. I also manually edited the gutters to suite the new shape. Please note that any manual edits should be done last as if the roof is redrawn any manual edits will be removed.
I then made made the two blue sections as separate roofs and then moved them into their positions. To get the shape of these roofs I made one end a gable and the opposite end I set the angle more than 90 degrees to match the adjoining roof pitch (180-adjoining roof pitch
is the best way to do it).
Would you be able to please let me know if this works for you?
The next version of PlusSpec (which will be out very soon) has an overhaul of the Roof Tools which will make doing more advanced roofs a lot quicker and easier to do.
Also, if you have any advance questions on how-to's we have a online one-on-on training service which I would recommend having a look into. The link below will take you to a page on our website which explains the training in more detail.http://plusspec.com/one-on-one-training/
