    Default Rotate a group that has a sweep

    We have a loading area canopy that is used a number of times in our project (see attached).

    I have modelled the canopy using in place components for the rafters & purlins. The roof has been made from an extrusion and the gutter is added as usual. These have then been selected and saved as a group.

    All works fine until I try to rotate the group.

    The rafters and purlins are deleted.

    Does anyone have any suggestions in this situation?

    If you create all the elements as part of the same in-place family Revit will should allow you to rotate them. You currently have separate in-place families fro the purlins, the roof and the gutter and each may have an different associated workplane. When you try to rotate the whole works , even if you group them, Revit tries to maintain the relationship of the individual parts to their individual workplanes and things break.
    If you feel you can't make this a component family, which I would suggest, then make it all one in-place family and see if that helps.

    Thanks for the help. I decided to model it up as a family. The Rafter and Purlins were modelled as generic families then inserted into my Canopy which was a wall based family.

    I guess it is not the best idea to group objects if they are a little more complicated and you should make most things families.

    To get it all to work I had to learn about linked parameters. Learned a lot...
