Pipe length ignored when set through API

[Anonymous]

I can change the length of a pipe by right-clicking it in the assembly tree, selecting "Change Size", and setting the PL field. However, when I do the same thing using the API, nothing happens and the pipe stays the same length.

// pdoc is the document for the pipe part
foreach (Inventor.PropertySet pset in pdoc.PropertySets)
{
    if (pset.Name != "Inventor User Defined Properties") continue;
    
    foreach(Inventor.Property p in pset)
    {
        Console.WriteLine(p.Name);
        Console.WriteLine(p.Value);
        p.Value = "20.000 in";
        Console.WriteLine(p.Value);
    }
}

I can see the value of both L and PL change from "10.000 in" to "20.000 in", but after the script finishes the pipe is still 10 in long.

when yoiu update any parameter inside part you must update your geometry. odoc.Update

But in your code you change value of iproperty ?  it will do nothing with your geometry. You must change parameter value. doc.componentdefinition.parameters...

Changing the values in doc.ComponentDefinition.Parameters and calling doc.Update() worked, thank you!

What are the properties for though, if they don't change the drawing?

trough iptoperties you can easy share information about your files. for example you can export parameters to i properties and use it in bom-s, drawings, exports etc.
