Aah ok got you. I've never used the feature like that. Let me have a look at the automation API and see if I can come up with something. Might be a few days but I'll definitely respond.
from pycatia.
This macro (in VB) can help for sure. I'm studying and translating it to Python. Let's see....

Sorry I've not responded sooner.
I've looked at the VB script and whilst it's certainly doable in python it's not something I currently have time to look at in detail sorry. Maybe in the near future.

How to get the user defined properties in part or product?
i am trying with "user_ref_properties", its throwing me a com error like below.
com_error: (-2147352567, 'Exception occurred.', (0, 'CATIAProduct', 'The method UserRefProperties failed', None, 0, -2147467259), None)
Can any one help me in that?

@tcrakshi This is unrelated to the original post. A new issue has been raised. I will reply to the issue there.

@mrjapon I see you faced this issue some time back. Were you able to make any progress on this?

Hi,
I think the key of this issue is getting a correct Inertia Object.
With pycatia 0.4.1, it can basically work.
# test Inertia
from pycatia import catia
from pycatia.space_analyses_interfaces.inertia import Inertia
caa = catia()
document = caa.active_document
product = document.product()
inertia_com = product.get_technological_object('Inertia')
my_inertia = Inertia(inertia_com)
print(my_ineria.density)
print(my_inertia.mass)
The density
and mass
properties can be obtained correctly. Methods like get_cog_position
or get_principal_axes
yet doesn't work.
I'm trying to solve this puzzle...
from pycatia.
Try this:
from pycatia import catia
caa = catia()
document = caa.active_document
product = document.product()
spa_workbench = document.spa_workbench()
inertias = spa_workbench.inertias
# clear existing inertias.
# this is required since the CAA object seems to keep the inertia collection in
# memory on each iteration of the script. Not sure if this is by design or
# something pycatia should be doing.
for i in range(inertias.count):
inertias.remove(1)
# add product to inertia collection.
inertias.add(product)
for inertia in inertias:
print(inertia.mass)
print(inertia.get_cog_position())```
from pycatia.
The
density
andmass
properties can be obtained correctly. Methods likeget_cog_position
orget_principal_axes
yet doesn't work.

Good luck! I've been trying to solve this and can't figure out the problem.
from pycatia.
Aha, that's the correct solution to get a exact Inertia instance. But it's pity I didn't find the bound box parameters directly.
I tried another solution, simply and directly translated from
This macro (in VB) can help for sure. I'm studying and translating it to Python. Let's see....
https://www.eng-tips.com/viewthread.cfm?qid=436208
from pycatia import catia
caa = catia()
document = caa.active_document
product = document.product()
sel= document.selection
sel.clear
sel.add(product)
caa.start_command("Measure Inertia")
print(f'BBLx: {product.parameters.item("BBLx").value_as_string()}',
f'BBLy: {product.parameters.item("BBLy").value_as_string()}',
f'BBLz: {product.parameters.item("BBLz").value_as_string()}',
sep='\n')
Here is one more issue should we pay attention, as CAA Document describe StartCommand:
Role:This method starts a command and executes it untill its first interaction. Please notice interactions such as selections you could add after in your macro will not work. StartCommand is useful to execute one-shot (not interactive) commands, it is not safe for interactive commands.
I think "Measure Inertia" is not one-shot command. To solve this, it would be anther issue #39.
@mrjapon, please check whether it is you mean.
from pycatia.
If I understand correct and you want the script to stop and wait for input from a user could you use a messagebox to prompt the user?
Hopefully I'll provide an example script tomorrow. 🤷♂️
from pycatia.
This is actually more complex than I thought to make it interactive, for a number of reasons:
- You can't make a selection whilst the message box is open. So my suggestion above isn't valid.
- You can use pythons inbuilt
input()
to halt the process, select the product, press enter to continue in the cmd window.- Having to switch between windows isn't user friendly.
- You still need to close / cancel the inertia tool once the data is read. This isn't insurmountable as
pywinauto
could do this I think (see example 18, not directly related but usespywinauto
). However, there is a bigger problem to solve ... see next.
- In a large product
product.parameters
returns ALL parameters for ALL loaded documents.parameters.item('BBLx')
will only return the first occurrence.- Well, we could loop through the parameter names and get those that include the product name and the last BBLx no? Not really, as this is way too impractical for large products as it's too slow from my tests.
This is going to need some more thought.
from pycatia.
I've tried win32gui.FindWindow
, win32gui.CloseWind
, win32gui.DestroyWindow
.
"Measure Inertia" Window can be find and close, but meet error when try to destroy. More work need to be done.
from pycatia.
This seems to work but comes with a warning. Please test thoroughly.
"""
Example 26:
Prompt the user to select a product and get it's bounding box parameters
.. warning:
Currently there must be NO other existing Measure Inertias saved
ANYWHERE in your product tree as these may be returned and not
product you have selected.

👍 Brilliant!

It's really good example everex,
I think it will ans for #39 issue.
def close_inertia_window(), this function is closing command dialog box,
so now I want understand is it similarly give input like yes/no/enter options, or recognise which all are button available in command dialog box and click on those button?
If it possible , thee we can address most of the issue, like generate catpart,. , Etc

It's possible.
However, it is done by pywin32, not pycatia. In this example, you can find it is win32gui play the role to close the window.
You can find more information by searching win32gui on Internet.

See example 20. message_box does what I think you're asking.
from pycatia.
Closing this as issue as I think it's resolved to a degree although the solution isn't perfect yet.
