It’s working for me. It would be difficult to tell if it is working or not unless you are looking at the group’s axes. I added some marks so it’s possible to see that the group has been flipped. What happens if you do that?
You can see the group’s axes when you open it for editing as I demonstrated at the beginning of my GIF. You could display the axes by going to Window>Model Info>Components and ticking the box however that will display all of the axes and it’ll get rather cluttered.
Oh, wild. – So I’m confused now, because what I was trying to do is mirroring. (To make that piece look like it’s opposite on the other side) I could have sworn that flip along axis was how I’ve achieved this many times in the past. - Do you know hat’s different this time?
Well, if your axes were aligned with the model axes while the geometry is angled, it would look like you are making the opposite side of the room. You could also select more than one group so you are flipping along the model axes instead of the group’s axes.
Here I exploded the group and remade it so its axes are aligned with the model axes. Note the huge bounding box.
Oh that’s very cool to know. Thank you! And that’s a neat trick grabbing a second group.
I didn’t realized that my group axes was not aligned the models Geometry. - I see what you mean now, the blue box surrounding the Group indicates how the axes is angled.
There are actually nine different Flip commands; three for multiple selections (more than one group or loose geometry, etc.), three for groups, and three for components. The three commands that are displayed is dependent on the selection. FWIW, you could just draw a temporary bit of geometry to select with the group or even select a guideline with the group before flipping.
The axis orientation is normally determined when you create the group. Considering where the axes are in that group, I expect you copied a group that was modeled on axis and shortened it to make this wall. then you rotated it into place.
Keep in mind that axis orientation can have an impact on how textures get applied when you edit the groups for that part of the modeling process.
Is this building being constructed from SIPs? It seems to be kind of an odd way to model a building in SketchUp.
