[Plugin] Volume Calculator2...

How do I add the VolumeCalculator v2 script to SketchUp?

pdpotter · 14 Feb 2008, 22:48

Thanks, Pilou. There was no Plugins folder in my Google SketchUp 6 folder, so I created one and copied the VolumeCalculator2.rb file into it. I then created a component which has connected faces forming a solid which has a volume. When I right click on the component, I do not see a Volume option. I do not have a Plugins menu item, either.

Perhaps it is because I am using the free version of SketchUp. Or perhaps because I am using a Mac (OS X 10.5.2).

Any suggestions?

I have a 2-button mouse (could have used Control-click for right-click otherwise), so that's not it. I think I should see an entry in the About Plugins menu, also, but I don't.

Pilou (and others)

I got it! On a Mac, you have to place the .rb file in the Library > Application Support > Google SketchUp 6 > SketchUp > Plugins folder. (This assumes that the SketchUp program exists in a folder called Google SketchUp 6 within the Applications folder.) Once I did that, the sub-menu included a Volume option. Thanks for your help, Pilou.

Ug. I cannot get this thing to appear anywhere in sketchup 6. I tried to put it in the "Plugins" folder or the "plugins/utilities" folder but it just won't appear.

It's not the pro version. Do you need pro to use custom scripts? Sorry if I'm missing something stupid.

Thanks,
Jack

Woa woa woa, never mind.

I knew I'd figure it out once I posted...

Sorry!

Hello again,

I'm having trouble with volume calculator, and I can reproduce the odd behavior:

Make a 1"x1" rectangle, push it 1" into a cube, draw a 0.25" circle in the middle and push it to the bottom of the cube to make a hole. Group it, and run volume calculator. It goes wonky! (I'm pretty sure it does this for all through-holes, but I wanted to be sure we're all doing it the same)

I'm using v2.1 and sketchup free 6. Any ideas?

Thanks!
Jack

Simply add it inside the folder Plugins of (Google) Sketchup
Instructions are in the header of the file: you can read it by a simple text editor (bloc note)

In this case just after a speedy use : you must create a goupe or a component before
Clic on this Group or Component and then "Volume" will appear on the "Right clic"

Seems work like a charm
This guy is this one

Seems that is the same for all volumes with holes
A solution is to cut the volume in 2 parts and add the volumes results
Now the calculator works!

Dear Gurkesaft,

Try TIG's version 1.8. It works fine with through holes

Bob

This is sad- what does v2.1 exist for?

watkins · 12 Oct 2008, 20:10

Dear TIG,

Do you think you might have time to look at your latest, fast version of the volume calculator? I am still using V1.8 as V2.1 seems to fail when challenged with one of my models.

Kind regards,
Bob

V2 was a quicker alternative way of accurately calculating volumes. v2 does it by 'slicing'...

Use v1 for more complex shapes (slow)
or use v2 for simpler shapes (quicker)

see which suits you best...

I currently don't have time to sort out v2 - if anyone else wants to tweak it, please feel free...

Dear TIG,

Okay, I will do that. Thanks for the response.

Kind regards,
Bob

is there any way to force a volume, i have a bottle design here and the client needs it to be 500ml and wants to know what the resulting dimensions would be.

If you know the current volume with the current dimensions, then you'll need to scale the current design by:

3√(targetvolume / currentvolume)

see a good reason to have payed attension in math class... i'll try

Did you ever say: "I'll naver have use of that!"..?

AdamB · 26 Mar 2009, 08:59

BTW Thats "cube root" not "3 times squareroot"

Perhaps TIG could be persuaded to add a function to Volume Calc that does this since I can see it must be pretty common to be wanting to get to a target volume.

Now if three men take four days to dig.. nevermind..

Dear Adamm & TIG,

Could the volume calculator be updated so that the newer, faster script doesn't fall over with multiple internal volumes? I am currently using V1.8 as that seems to work well for complicated shapes, but it does take a long time when the precision goes up. Further, while easily calculated by hand (once one knows the volume), could an editable drop-down list of densities be added so that the script works out the mass as an option. Typical densities would be for concrete, steel, wood, water, sand etc.

Another option would be to assign materials properties to components (is this possible?), and then to get the script to work on an assembly (such as a wooden cabinet), treating each component separately (volume and mass) returning a table (spreadsheet) of volumes and masses with the total mass. This could be useful in assessing loading, lifting and shipping requirements. The calculations for C of G are very similar to those for volume (slicing the model), so that is yet another option, as is moments of inertia.

I'm sure you are both very busy, but I offer these few thoughts for consideration.

Regards,
Bob
