hey has anyone got any detail or tips on how to curve the slightly bent line following the shape of the semi-circle cut out tubes, I need to connect it all but I am struggling to do so, thank you
See this SU file for ideas.
Semi circle face with a curved path.skp (142.8 KB)
If it is not what you want to do, can you post your skp file ?
In this discussion I put the link of a tutorial to bend any shape with TRUEBEND plugin:
how did you paste back the deleted face
He hid the face to be able to work inside then unhid it when done.
To hide: Right click on the face to bring a contextual menu then click on Hide.
To reveal or unhide: Edit Menu → Unhide → All (or Last).
