How to PROGRAMATICALLY make exported WorkFeatures invisible in the assembly

[oransen]

Now, thanks to this forum, I know how to how to make exported WorkFeatures invisible in the assembly manually I need to know how to do it with the Inventor API.

I presume there is a function which takes the assembly definition and the part occurrence,  but I can't find it in the API docs, or an example...

What do you mean by exported work feature?

Are you talking about work features from parts that also appear in assemblies? (work feature proxies?)

And what is your criteria for deciding which work feature to toggle on and off?

What you need to do, regardless, is get the proxy of the work feature as it exists in the context of the assembly and modify that in order to control the visibility of the work feature for that specific occurrence.

However, you could also access the part directly and just modify the visibility of the work feature in the part so that work feature shows up in none of the instances of that part.

if you already have the partOcc defined try this

partOcc.Definition.Workplane.Item("workplaneName").visible = False

It should work the same for axis and points just substitute accordingly.

Hope it helps

>>  partOcc.Definition.Workplane.Item("workplaneName").visible = False

I think that refers to the original part and not the part as it exists in proxy form inside the assembly.

Thanks MechMachine, the trick was getting the proxy of the workplane. I only have it in C++ but here's how I do it...

    CComPtr<WorkPlane> pPianoSupWP=nullptr ; 
    hRes = pFondCompDef->WorkPlanes->get_Item(CComVariant (L"PianoSuperiore"),&pPianoSupWP);
    if (FAILED(hRes)) {
        ShowCOMError(hRes, L"Could not get PianoSuperiore of the fondello");
        return;
    }

    CComPtr<WorkPlaneProxy> pWPProxyA ;
    hRes = pFondOcc->CreateGeometryProxy (pPianoSupWP,(IDispatch**)&pWPProxyA) ;
    if (FAILED(hRes)) {
        ShowCOMError(hRes, L"Could not get proxy PianoSuperiore of the fondello");
        return;
    }

    hRes = pWPProxyA->put_Visible(VARIANT_FALSE);
    if (FAILED(hRes)) {
        ShowCOMError(hRes, L"Could not get set proxy visibility");
        return;
    }

I forgot to mention that this is how the problem started. If the feature exported is in the iPart table then it seems to be always visible in the assembly that uses that iPart. Even if you set it to be invisible in the iPart itself...
