Python Scripting for Inline Components

ryan.schmitz3D8X3 · ‎03-11-2021

Hi, I've had success creating pythons scripts and implementing them in catalogs/specifications for pipe supports, but I'm having difficulty with inline components. I'm trying to create a strainer with a third port at the basket. When I test the script using the TESTACPSCRIPT function everything works correctly and the component is created at the origin. However, when I create a new component using this script and then add it to a specification I get the following error when inserting the component into Plant3D, "Can't find symbol for specified part". I used the same methodology that I used to create support components and add them to a specification. Any idea why this wouldn't work in the spec but works in the TESTACPSCRIPT? I'll add the script below and hope that helps.

Dear @ryan.schmitz3D8X3 ,

there seems to be a problem with your script.
I get this error message after "PLANTREGISTERCUSTOMSCRIPTS"

Befehl: PLANTREGISTERCUSTOMSCRIPTS

@ryan.schmitz3D8X3Hi, please remove the indention error on line 30. write your script as per attched image.

The script must have been copied over correctly. All lines after "def ESY85TEST(..." are indented by one tab. That is not what is causing me the issue atm.

h_eger · ‎03-12-2021

may be yes, but at PLANTREGISTERCUSTOMSCIPT I get the error message from line 30 to compile the script.
Now we can discuss for a long time - it still doesn't work!

Rajendra,

When you indented all lines after def ESY85TEST... did you still have problems compiling?

I don't have any problems compiling this script, but the other commenter says it doesn't work for him.

My issue is currently at the catalog/specification level. This script when used to create a catalog component and then placed in a specification will throw an error when trying to use the component in the specification. It's odd cause if I run it via the TESTACPSCRIPT command it will work.

If you have time, please let me know if the script compiles for you and if you are able to replicate this catalog/specification issue.

Thank you for your time Rajendra.

Replace the 'tabs' with space(s). The compiler doesn't like tabs.

I replaced the tabs with spaces as suggested. It still compiles and works with TESTACPSCRIPT.

The problem is with the Catalog and Specification.

I attached screenshots of the properties and sizes tabs for the created component.

I add this component to a specification then try to insert it into a Plant3D Model and get the following error:

"Geometry can not be generated with the given parameters."

"Can't find symbol for specified part."

Any ideas? Was anyone able to create a catalog component, import it into a specification, then add it to a Plant3D model?

Wow that did it! For some reason it only works in catalogs/specifications when I remove the inner radius for the cylinders. How you figured that out is beyond me. Kudos!

This issue has to be an error on AutoCAD's part because I've used hollow cylinders for supports in catalogs/specifications with no problems. I'd be very interested to know why this is an issue for inline piping components.

Thank you very much Ranjendra, I appreciate you taking the time to help me out.

hi guys, how are you all?

Now is my turn to ask. I'm having trouble to make a simple nippled ball valve python script to work properly.

It is a bit frustating, it's been three days of tests, but all aI've got is the block correct.

When I try to create a cusstom part from it, the properties doesn't show me the parameters.

When I insert the valve into the catalogue and try to create the valve, as a pipeline asset, in plant 3d, the geometry is wrong, the nipples aren't equal, the length isn't correct. And I cant't assignan actuator, it doesn't appear. Then...

1 - Could anyone help me debug the script, is that anything wrong with it?

2 - How to assign the valve actuator to a valvebody created via python script ?

I found this page: https://knowledge.autodesk.com/support/autocad-plant-3d/learn-explore/caas/simplecontent/content/pla.... Still figuring out.

Thanks
