I am working with a manual, where I need an assembly drawing. I have 3 step files, one of a panel board, one of a cable tray and the third one of a wall bracket. Now I would need to combine them all in one .smg file to be able to get the parts in the correct perspective. I have managed to import them all in one file. I can drag the parts in different positions. But I don't manage to rotate the parts separately, instead the entire view rotates. Does the Composer even support this kind of modifications? Or is the only possibility to modify each part in their own files and then open them for example in Illustrator for the final assembly?
