There's a wee bug. It adds the CPoint in model.entities instead of model.active_entities - so if you use this inside a group/component it's not added to the correct context.

Chris, you're a mind reader...I was looking for this function for a long time. Thanks for your help in our sketchup's lives !!

Oh darn, there was a little while there where I think I forgot about .active_entities and just added everything to the .entities collection. I'll fix it and get it uploaded later today,

ok, now updated so that when it is used in group/component edit mode, it will add the construction point inside the group that is being edited. Thanks for pointing that out Thom.

So re-download it from the first post in the thread.

Thanks Chris,

I found this to be a very readable script for learning a little more Ruby. It's pretty clear from context what it's doing as far as finding a perpendicular direction, creating a temporary "z" from the original two edges, etc. I assume the ".cross" function is the Cross-product from vector algebra, which I vaguely remember, but I'll have to look up what that actually is and why it's called "cross".

Thanks again,
August

i know it may seem stupid, but why can't i see the context "point at center" menu when i right-click on an arc?

You have to first enable the sketchup ruby script examples from Window > Preferences > Extensions > Ruyb Script Examples (or might be the one called Utilities tools). Enable them both, then you should get the point at center option.

ha!
i never knew this function came with SU.. i've been using jim f's arc_centerpoint.rb for a couple of years now.

Jim

Hehe, and I wrote that before I realized Point at Center came with SketchUp!

Me too, seems that the ways of SU are infinite!

Thanks for the tip, Chris.

I just wanted to thank you again for this Chris. It is a very useful tool.

Dear Chris,

I made a request a little time ago for an icon to go with this script. I use your centrepoint finder so often that an icon would be very useful (and yes, TIG, I know I could assign a shortcut...)

Many thanks,

Bob

hello Chris thank for this Plugin but after I updated my SU8 to SU8m2 it was not work when I run in form plugin menu show to me this window I don't know what is meaning ?
note I removed it and instal it again but same problem

Hi, jamalito:
It appears you have preselected a non exploded arc. Chris's plugin is for calculating a centerpoint of 2 or more unconnected or nonwelded segments. Use Sketchup's native Point at Center or Jim's Autocenterpoint.

Had this very handy plugin installed previouslyu but I had to reintall Sketchup today.
I tried installing via the Sketchucation plugin store but it didn't work so I manually placed it in the plugin folder and but doesn't appear in the plugins menu.

Am I doing something wrong?

Yes.

You didn't actually install the plugin. files with the .rbz extension are intended to be installed via Install Extensions under Preferences>Extensions. Put the file back into your Downloads folder, or wherever it was downloaded to. Open Preferences and go to Extensions. Click on the Install Extension button, navigate to the file, choose it and open it. Most plugins will work after this install but it won't hurt to close SketchUp and reopen it.

BTW, could you please complete your profile? Which version of SketchUp are you using?
