How to properly create triangular meshes?

I am trying to model a triangular roof where its edges are in different coordinates as shown in the video WeTransfer - Send Large Files & Share Photos Online - Up to 2GB Free

I wonder if there is a better way that I don’t know yet, or a plug in that can make it like magic… :smile:
Because Iam having such a hard time to do this :neutral_face:

I found this plug in but it work only in 2016 sketchup

Can you explain what you are trying to do?
The video is not very clear…

Iam trying to “close” those edgy triangles, but using follow me tool doesnt work this way

You need to start again on the roof !
If you do succeed in modelling it, then it will be all but impossible to built.

First switch off Model Info > Units distance snapping - it’s not helping you draw.
Also work in Monochrome mode to ensure reversed faces are avoided and you can clearly see what you are doing…

Now inside its own group make the simple outline of the roof - bottom and top flat faces.
Join these two flat faces with corner edges and they should auto-form faces for the fascias.
Because you have some weirdly sloping walls below the you cannot create a single face for the fascia, and will need a diagonal to ‘fold’ the fascia to work in 3d - in reality the builders are unlikely to think this is a good idea.
The wall faces below might also need folds in their planes to work in 3d - again a costly and difficult thing to achieve in reality…

Your existing roof model has many short edges and bits floating around which prevent simple face creation, if when the diagonal ‘folds’ are expected…
