How to create manual tabs for a 2D contour

[billostratum]

I'm trying to programmatically create tabs for a 2D Contour. I haven't found any advice in the documentation as to how to go about this.

I started with this;

operation.parameters.itemByName('group_tabs').value.value = True
operation.parameters.itemByName('tabPositions').value.value = [point3d, point3d, point3d, point3d]

The first line works, but I can't find the proper format for the second line. Everything I've tried gives me a generic "parameter error".

I have Point3D's available that are guaranteed to be on the Profile that is the source of the chain inputGeometry.

I know this is not a full example, but does someone know what type of value is expected by this parameter? If I use the UI to select points, it lets me select any random point and the Select field shows that I selected a Point. That would indicate to me the tabPositions parameter is expecting a list of points.

Thanks,

Bill

Additional info.

I created a manual tab in the UI and then inspected the tabPositions parameter value.

The value is: 

<adsk.cam.CadObjectParameterValue; proxy of <Swig Object of type 'adsk::core::Ptr< adsk::cam::CadObjectParameterValue > *' at 0x0000014F89C777B0> >

I never know how to dig deeper once I see a Swig proxy.

hi,

You don't have to care about the Swig's proxy (it makes reference as how it is implemented internally).

You have to deal with the object type, which is a adsk.cam.CadObjectParameterValue:

So, in this case, use its value property to discovery the objects it references.

I hope this can help.

Hi,

The following snippet works for me:

des: adsk.fusion.Design = app.activeDocument.products.itemByProductType('DesignProductType')
cam: adsk.cam.CAM = app.activeDocument.products.itemByProductType("CAMProductType")
contour2D = cam.setups[0].operations[0]

poss_list = [des.rootComponent.sketches[0].sketchPoints[i] for i in range(5,9)]
contour2D.parameters.itemByName("group_tabs").value.value = True
contour2D.parameters.itemByName("tabPositions").value.value = poss_list

Take into account that the tabPositions array expects SketchPoint's instead of Point3D's objects.

In the example I'm using sketch points 5th to 8th defined in the sketch.

This is the result once I run it:

The value of the CadObjectParameterValue is another swig proxy

<adsk.core.BaseVector; proxy of <Swig Object of type 'std::vector< adsk::core::Ptr< adsk::core::Base > > *' at 0x0000014F89CC9F20> >

  This sounds like it's related to a Vector, but it has no properties (other than thisOwn).

Thanks. That's exactly what I was looking for.

I'll give that a try. I have to get my points as SketchPoint's somehow. Right now I have SketchCircle's and I am using their centroids.

To complete the thought, here is my completed snippet:

	_tabCircles = sketch.sketchCurves # all curves in the tab sketch are circles
	_tabCenters = [c.centerSketchPoint for c in _tabCircles]

	camOp.parameters.itemByName('group_tabs').value.value = True
	camOp.parameters.itemByName('tabPositions').value.value = _tabCenters
	camOp.parameters.itemByName('tabWidth').value.value = _tabDiameter
	camOp.parameters.itemByName('tabHeight').value.value = _tabHeight
	camOp.parameters.itemByName('tabPositioning').value.value = 'tabCount'
	camOp.parameters.itemByName('tabsPerContour').value.value = 0
