How to get the center of gravity coordinates of parts？ about pycatia HOT 11 CLOSED

Just cloned the repo and run the tests. That test does not fail here.

You mean the last method in your test file?
Thank you!

I think you're talking about this

This isn't the last test and while I commented in the code that it failed all the tests do pass (this test is commented out). I wrote these tests sometime ago so I'd forgotten about it and your posts confused me.

I'll have a look at this and see if i can solve it.

I'm really talking about this. I set part_body as reference but couldn't get the center.
I don't know whether it's my own problem or any other problem or not. After seeing the post, I found that you also encountered this problem, so I came to ask you.
Thanks again！

This works for me.

from pycatia import CATIADocHandler
from pycatia import CATIAMeasurable
from pycatia import create_measurable
from pycatia import create_spa_workbench

measurable_part = 'tests\\CF_catia_measurable_part.CATPart'



with CATIADocHandler(measurable_part) as handler:
    catia = handler.catia
    document = handler.document

    center = (-47.039, 83.488, 0.0)

    spa_workbench = create_spa_workbench(document.document)
    part = document.part()

    body = part.get_body_by_name('PartBody')

    body_reference = part.create_reference(body)
    body_measurable = create_measurable(spa_workbench, body_reference)

    catia_measurable_body = CATIAMeasurable(body_measurable)
    catia_center = catia_measurable_body.get_cog(catia)

    print(catia_center)

Does this method not apply in the products documentation?
For example, I want to get the center of gravity coordinates of a part in products.

I want to get the center of gravity coordinates of each part in an assembly, and judge the relationship between each part through some algorithms. And I'm sorry that I didn't tell you that I used Visual Basic 6.0 to do CATIA development. Thank you for your reply. You don't need to help me. Let me find a way for myself. If I solve it, I'll let you know at the first time.

I've just pushed some updates to the Master branch that'll help you do what I think you want.

Take a look at example_10.py.

I think I still need your help. This is my code written in VB:
Dim part1
Set part1 = selection1.Item(1).Value
Dim ref1 As Reference
Set ref1 = part1.CreateReferenceFromObject(part1.MainBody)
Dim TheSPAWorkbench As Workbench
Set TheSPAWorkbench = CATIA.ActiveDocument.GetWorkbench("SPAWorkbench")
Dim TheMeasurable As Object
Set TheMeasurable = TheSPAWorkbench.GetMeasurable(ref1)
Dim VOL
VOL = TheMeasurable.Volume 'Return the volume of part1
Dim coords(2)
TheMeasurable.GetCOG (coords)
Dim x1, y1, z1
x1 = coords(0)
y1 = coords(1)
z1 = coords(2)

Part1 is a part body, I can get the volume of part1 in this way. But I use GetCOG to get the center of gravity coordinates and return null values. I don't know where the problem is.

Where is your python code? VB code is no help to me.

I'm closing this as it doesn't seem to be related to pycatia.
