[Plugin] Exploded Arc Centerpoint Finder UPDATE May 23, 2013

Chris Fullmer

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.

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?

Chris Fullmer

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.

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

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.

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?

Dave just beat me to it...
BUT since I had typed this here's my equivalent text...

You must be doing something wrong
Installs fine for me ???
I assume you are on v8 or v2013 your User-Profile is incomplete...
If it's v8 you need the latest version to be able to AutoInstall RBZ archives.
If you have manually put the tool's RB file into the Plugins folder and restarted SketchUp then the tool should appear in the submenu Plugins > Chris Fullmers Tools...

If it's not in there you haven't actually installed it right...
If it is, then it has loaded.

Some common reasons:

You left it inside the RBZ - SketchUp only auto-loads RB/RBS files it finds within the Plugins folder as it starts...
You don't have Properties > Security permissions set to FULL, which allows you to add files to the Plugins folder.
If so it might look like you added it but a 'Compatibility Files...' link/button in the top-bars of the Windows Explorer window for Plugins is a give-away that its actually in a VirtualStore - from where it won't load when SketchUp starts !
Fix your permissions.
Also set SketchUp.exe to always run as administrator in Properties > Compatibility...

Is there a version for SU 8?
Thanks

TIG

What makes you think it's not v8 compatible ?
The previous post explained how to install it in v8 - but you do need the latest v8 version with the Preferences > Extensions > Install... button.
If you don't have that, then get the latest v8 installer from here:
http://help.sketchup.com/en/article/60107
Note how version 8 will no longer be supported after 20 May 2015, so keep a copy of the downloaded installer !
