[Plugin] Center of Gravity
-
Seems to work fine on PC but on Mac it falls over... I WILL find a solution...
-
I'll try it on an sterile Mac i.e. just on it's own, see what happens, give me five minutes
-
Same error when v1.4 + debabelizer are the only rubies installed
-
TIG,
It's not all Macs that have problems, though. It works just fine on mine. Could it be another plugin or something?
-
As I suspected
I'll sleep on it... and see how I can devise a work around in my sleep...
PC works fine - come on Mac's what's up with you !!!
Is it a particular version of Mac OS and the Ruby version that they have ??? -
well, mine are
both running SU 7.1
both running OSX 10.5.8
both running Ruby version 1.8.6
MacBookPro is a fresh SU instal with just v1.4 bits
iMac is littered with rubies but very few clashes are left roaming free, it is also running rubygems, but that doesn't seem to effect any thing else in SUboth give same error

Must be something wrong with my Mac, then.
-
-
Very funny. I have both and I know the difference.
Here's proof that it works on my Mac.
-
works ok on my Mac but TIG Tools folder replaced existing one so extrusion toolbar icons disappeared. I see missing icons on Dave's screenshot also.
-
Most mysterious. I have tried with no other plugins or tools in the respective folders and using CofG version 1.4 I still get:-
Error; #<NoMethodError; undefined method `db' for CofGravity;Class> /Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb;156;in `do_calculation' /Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb;816 /Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb;156;in `call' /Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb;156

"Merge" the folders so that the other existing files are kept - just overwrite any files for that specific tool...
-
Thanks for noticing that Wind-Borne and thank you TIG for the fix.

I have translated the plugin to Spanish language, bottom i put de link for download. I see that other Mac's users have the plugin working fine, to me no works, i use Sketchup 7.1 in Mac OSX Snow Leopard 10.6.2 and the last version of the plugin CofG_1.4, i have tried run sketchup with CofG in the plugins folder only, and don't works, SU read the plugin, i see the plugin (in spanish) in plugins Menu but don't works.
When i run the plugin this message appears in Ruby Console:
Error: #<NoMethodError: undefined methoddb' for CofGravity:Class> /Users/Oxer/Library/Application Support/Google SketchUp 7/SketchUp/Plugins/CofGravity.rb:156:in

We have been PMing about this - the Mac db glitch is known and driven and I are trying to track it down.
Please PM me the CofG ES lingvo file and I'll publish it with acknowledgment of your input - hopefully with a fix for this Mac/Ruby glitch...
-
Here's 1.5
I've reworked the code to suit all Macs as well as PC.
A ES lingvo file has been added - by Oxer.http://forums.sketchucation.com/viewtopic.php?p=229401#p229401

Congratulations TIG! It does indeed wor=k on my machine now - what was the issue?
I don't wish to sound as if I am complaining but it seems rather slow to come to a result even for a very simple block shape.
-
Yes, for the iMac....
-
and also a yes for the Mac book...

I don't wish to sound as if I am complaining but it seems rather slow to come to a result even for a very simple block shape.SketchUp is not a solid-modeler so I had to devise a psuedo-integration trick...
It is somewhat slow as it always makes 200 slices through the form, and gets the centroid of each slice and then amalgamates these to get the final CoFG. I choose 0.5% as I felt it more than covered most likely forms. If the shape has lots of convoluted edges or internal voids/holes the centroid calculation gets even more complicated as these must sometimes be deducted from the sub-total as we go etc... If you want a less accurate result you can change the@percent
variable in the script to say=0.1
(1%). Unless there are lots of very small comb-like horizontal ribs the answer might be accurate enough at an even lower percentage... The time taken to do a simple block is little different to a complex form as the 'slicing' and calculations are the same...
I originally wrote it for someone making very detailed stone carving for restoration, and these need to be lifted into place very carefully so accurate axial Suspension-Points are vital - these come from the CofG... Waiting a few seconds to get a good answer seems appropriate in the circumstances as weeks of work could be lost in placing the item should it not be balanced properly...
