[Plugin] C of G Reporter 1.3

TIG · 10 Oct 2010, 14:36

working but :
CoG Report File:
'F:\neo batitrad\Bar & Ka/console_CofG_Report.csv'
Cannot be written - it's probably already open.
Close it and try making the Report again...
Exiting.
nil
and it's not open, cause it's not written yet !

Try renaming the folder 'Bar & Ka' to 'Bar_Ka' - The '&' in the file_path might be the culprit ?
Also is your model SKP really called 'console.skp' ?
Try the version 1.2 which has more error messages, that might report what is really up...

Here's v1.2 http://forums.sketchucation.com/viewtopic.php?p=278046#p278046
with some extra error reporting to try and trap Bertier's reported cryptic error messages...

thank you TIG

I'll try this tonite, got to get the kids at their grand parents now.

where are you from ?

It's a secret but there's a clue in his profile

If accents are forbidden, that is very annoyous for French Windows System
Because there is an accent for the principal Desk and for some of path! !!!
C:\Documents and Settings\Propriétaire\Bureau

PS I have not the use of this plug, but it's by curiosity

Of course now I obtain nothing
except this (i have saved my object with Cof as Untitled.skp
curious is the "/" and ""

cofgreporter
No such file or directory - C;\Documents and Settings\Propriétaire\Bureau/Untitled_CofG_Report.csv
CoG Report File;
'C;\Documents and Settings\Propriétaire\Bureau/Untitled_CofG_Report.csv'
Cannot be written - it's probably already open.
Close it and try making the Report again...
Exiting.
nil

Edit: That works when I use a path without accent for save my file!

The Unicode paradox is an annoying bit of Sketchup's Ruby - some of the 'File' functions don't work properly if there are accented characters etc in path_names etc... Sorry!
At least we know the cause of the problem...
The \ / is also from the same methods when you get the filepath on a PC it has \ separators [/ on MAC], when you join on the new file_name it's always with the as the ;joining; separator / - but it still works OK...

Bertier · 10 Oct 2010, 20:05

there is no accent in my path ....

cofgreporter
undefined method `definition' for #Sketchup::Group:0xe005344
CoG Report File:

Have you save your file SKp in the samme path?

TIG · 10 Oct 2010, 22:50

Bertier
Did you install v1.2
Although it might still fail you should get more error messages...

TIG · 10 Oct 2010, 23:01

Heres's v1.3 http://forums.sketchucation.com/viewtopic.php?p=278046#p278046
It corrects the glitch that a few users might get with 'group.definition' - OK if you have some of my other tools installed but not this one alone - now sorted...
Please try and report back...

Bertier · 11 Oct 2010, 03:39

hooray !

it's working :

cofgreporter
CofG Report written to
'F:\neo batitrad\Bar_Ka/console_CofG_Report.csv'
nil

nice.

for some reason, using CoG makes SU "not responding"....

any clues ?

any clues ?

There's a lot of intensive stuff needed to 'integrate' possibly hundreds of slices through the selected object and find their common centroids...
You should get a 'count-down' 'nnn of mmm' report in the VCB and then a '...processing ......' ?
It will finish eventually...

Hi, this is a very interesting plugin. I'm going to try it.
Two things struck me.

1st The rounding of numbers (but this is something I can work with ... )
2nd Hollow objects (pipes, etc.) are calculated as full volumes.

Can this be repaired with the hollow objects? That would be great.

TIG · 23 Sept 2011, 08:30

You can edit the number of dp's in the code - in the lines around the first half of the 300s...
I'm unsure about your comment - objects that are individual 'solids' are reported correctly - even when there are hollows. However, if you combine objects into a group it will by its nature cease to be a true manifold solid as there are internal 'partitions' - therefore sometimes the volume calculations can be awry. You should take the CofG of the parts and then make a combined CofG - this is also important if the parts have different densities...
Can you supply an example where manifold solid objects are returning incorrect values.
This one returns proper results even if the two groups are nested into one, as the 'slices' needed to calculate the CoG are maintained - but it is not always possible...

I installed this plug in today but it does not appear on any of the SketcUp 2023 menus. How do I get a report?

TIG · 14 Sept 2023, 11:56

Read the first post in this thread...

@unknownuser said:

Usage:
Use this after adding some CofG's [i.e. 'Center of Gravity' tags]
Type 'cofgreporter' in the Ruby Console.
If the Model SKP is new and has not yet been saved you will get an error.
If there are no CofG's to Report you will get an error.
If the destination CofG Report cannot be written -
e.g. it's already open in Excel - you will get an error.
Otherwise a CofG Report is written into the Model's folder.
It is named to match the Model -
e.g. 'MyModel.skp' and 'MyModel_CofG_Report.csv'
A '.csv' file can be opened in Excel etc.
Link the .csv into a pre-formated .xls file with additional 'sums' etc, so
that it auto-updates.
It is sorted alphanumerically and reports
'ID' 'Weight' 'Volume' - the final two are in the units used in the CofG's.
The 'ID' is the CofG name-tag based on the original Instance's name, but
remember that you might have adjusted this in the dialogs during the making
of the CofG's - i.e. it is as displayed in the CofG's text-tag, not
necessarily the Instance's name.
