Rotate a group that has a sweep

[Bastiat]

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?

I try it this way,nested it and then group them , and it works when rorate the group,like the below
it is strange, the element can be rorated as single one, but go wrong when in a group

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...
