Issues querying coordinates from construction points

[en9y37]

Hi there.

I have defined one construction point within each component in my design by the three planes method.

If I query the coordinates of this construction points using the API Object Explorer, I get the right coordinates if I select the construction points directly from the browser or from the Time Line:

The issues come when I query the coordinates via this object:

component.constructionPoints.itemByName('_O_').geometry

The coordinates I get in this case are these:

I have also tried to get these coordinates through the timeline, and the output is still wrong:

Any idea about what object should I use to get the right coordinates?

In order to give more information, I've just noticed that the coordinates issue only happens in those components in which their own coordinates systems don't match the root component origins.

In this case this happens because one component was created by simetry from another.... I'll keep on researching

Hi @en9y37 .

Try this.

# Fusion360API Python script

import traceback
import adsk.fusion
import adsk.core

def run(context):
    ui = adsk.core.UserInterface.cast(None)
    try:
        app: adsk.core.Application = adsk.core.Application.get()
        ui = app.userInterface
        des: adsk.fusion.Design = app.activeProduct
        root: adsk.fusion.Component = des.rootComponent

        msgLst = []

        for occ in root.allOccurrences:
            comp: adsk.fusion.Component = occ.component
            for constPoint in comp.constructionPoints:
                point: adsk.core.Point3D = constPoint.geometry
                point.transformBy(occ.transform2)

                msgLst.extend(
                    [
                        f'<< {occ.name} : {constPoint.name} >>',
                        f'ConstructionPoint.geometry : {constPoint.geometry.asArray()}',
                        f'transformBy(occurrence.transform2) : {point.asArray()}\n',
                    ]
                )

        ui.messageBox('\n'.join(msgLst))

    except:
        if ui:
            ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

Thanks a lot @kandennti !!!!

That works great. You saved me... again

May I ask, where do you find this "API Object Explorer" !?!

It looks very handy!
