Sorry for bringing up an 8-year old thread but what does "edit session" mean? (what TIG said)

I don't know why selection is lost when I mirror entities and don't erase original selection. On the video tutorial selection skips to newly-created geometry which is expected behaviour. In my SU after mirroring, nothing is selected.

Does anyone know how to install and find Smustard's Camera Controls toolbar? The folder I downloaded contains RB files. I put the entire folder into SketchUp plugins folder but I'm not sure it's the proper way to do that.

When I googled CameraControls, there appeared a thumbnail of a movie tutorial on smustard's webpage but I cannot open it.

So simple, so good! Finally I can snap to compo's center when rotating

Yes, tkanks, I'm aware that the numbers of segments should match. But actually my problem is different. I still don't know why I cannot UNDO (in the second case) and why I cannot MATCH VERTICES (in the first case). Looks like something's missing in the plugin's core, with all the respect to Fredo.

Fredo, your plugins are mindblowing!

I had SU 8 and usually when I installed a plugin there appeared new buttons in the interface. Now I'm using SU 2016 and some of them (e.g. Eneroth's 3D rotate and Smustard's Weld) appear only in the upper toolbar (File, Edit...) which is uncomfortable. To contrary, Fredo's tools still appear as separate toolbars, that's fine. Anybody knows how to show hidden buttons?

Thank you! If I could use only one plugin in SU, that would be Curviloft
