Hi,

Have you try this ?

Hi,

Have you tried turning off the Allplan welcome menu? See image below.

Best regards

It sounds like Allplan is freezing due to blocking execution. Maybe try running your function in a basketball stars separate thread or async loop?

PythonParts won’t auto-start on application launch or run in the background, which creates a limitation similar to handling a slope in a controlled workflow. They only execute when explicitly called (e.g., placing the element, updating it, or running via the PythonParts palette). So if you’re expecting it to “just run” when Allplan starts, that won’t happen by design.

as the documentation Link leads to old Version, (and was updated for Version 2026), maybe the info helps :

Hi,

Here's an example where ALLPLAN is launched from the command line and opens a specific project.

A PythonPart script is also launched with a custom argument.

The PythonPart recognizes the command-line launch, executes (here read an Excel file and generates cubes - external data for placement point, size and color -), and closes ALLPLAN cleanly at the end.

It's also possible to run scripts periodically on Windows using the Task Scheduler, for example.

=> ALLPLAN 2026
edit the paths into ps1

$allplan  = ".......\Allplan_2026.exe"
$script   = ".......\ExternalLaunch.pyp"
$dataPath = ".......\Data.xlsx"
$projectXml = ".....\Prj\xxxxx.prj\Project1.Dat.xml"

and check py / pyp location
