I did the same thing... When I was an admin/moderator whatever I was getting into political arguments in the bar and thought it unbecoming for someone of authority to be waving around flags or personal opinions. Strangely though, I pretty much stopped doing it after I resigned my post. Perhaps, like me, he'll stick around even without the title. Hope so.

Thanks to the three of you for your offers of help. Jean Lemire sent an illustrated procedure that cured my mistakes.

This might be helpful.

Dale, thank you for the complete reply. It is very helpful and works. Gary

Thanks for the directions

Your arch arc isn't on an axis - it's slightly off.
This is itself mightn't cause an issue, but if you pick points locked axially it could be a problem...
Try recreating your arch arcs parallel to the the green/red axes, find the center point and re radially array the 'dowels'...

Under the extensions tab, you can only activate already installed extensions. These extensions are generally plugins written in a simple text format with a file extension *.rb (sometimes *.rbs) referring to the file type " ru by" (the scripting language of SketchUp plugins).

Some more complex plugins may contain other file formats, too (like images for toolbar buttons) and are generally placed inside a *.zip archive that you need to unpack to the same place where you would install *.rb files.

In SU 8, there is a possibility to rename this *.zip archive to *.rbz (or " Ru By Zip") and directly install the extensions/plugins with this "Install extension" button (i.e. you need not go to your Program files... > ... Plugins directory to manually copy/unpack files there). But you only use that button for these *.rbz files.

Hi folks.
