Mirroring groups / Surface pattern hatch problem

[jj mac]

This one is hard to explain, so bare with me...

The building model has two towers - one is a portion that is oriented perpendicular/parallel and the other is a portion that is skewed on a slight angle - like 13 degrees or so.

Basically, we have a group file that contains everything to make up a suite... walls, doors, floor finishes, cabinetry etc... When we load the group file into the host file, the group gets mirrored to another location. When we mirror the group, the tile surface pattern - which is a 12" x 12" tile - on the finish floor rotates so that one is perpendicular/parallel to the monitor and one is skewed on angle. This happens as soon as the group is mirrored.

When the group was created, it was created on this slight angle.

I have used a scope box to orient this portion of the model to be perpendicular/parallel to the screen and the origin of the groups "x/y axis" remains on this skewed angle as if the groups axis is not affected by the view rotation.

What I want to know is if there is a way to change the rotation of that "axis" or if there is a different process/technique to follow when creating the group.

Ideally, we want the floor tile and the groups "x/y axis" to be perpendicular to the walls at all times.

Thanks in advance for any help!!!

Make sure that you are using a model pattern instead of a drafting pattern for the surface material of the floor. The pattern should rotate in the model without any problem.

The group rotation can be rotated to be parallel/perpendicular to the walls - select the group then rotate it's x/y axis to match the walls. We've done this on a couple of projects with multiple angles.

I'm not sure why you are using "scope boxes."

One thing to look out for when mirroring and rotating model groups of rooms is wall face hosted components (wall cabinets) and line based components(countertops and shelfs). If using these in the model group the components could start showing up in places you didn't expect. We found this in Revit 2008 and 2009 but won't likely test it in 2010. To avoid this, recreate any line-based components to be nonline-based and wall face hosted components to not use wall hosting.
