How to automate Annotation creation at any node?

Pernelle Marone-Hitz

One can create annotations at node ID using following code:

nodeID = 1984
analysis=ExtAPI.DataModel.AnalysisByName('Static Structural')
resultObject=ExtAPI.DataModel.GetObjectsByName('Equivalent Stress')[0]
probeLabel = Graphics.LabelManager.CreateProbeLabel(resultObject)
probeLabel.Scoping.Node = nodeID

with Transaction():
    labelsForRes = Graphics.LabelManager.GetObjectLabels(resultObject)
    Graphics.LabelManager.DeleteLabels(labelsForRes)
    probeLabel = Graphics.LabelManager.CreateProbeLabel(resultObject)
    probeLabel.Scoping.Node = nodeID 
    probeLabel.Note = "NOT OK"
    probeLabel.Color = Ansys.ACT.Common.Graphics.Color(red=240, green=0, blue=0, alpha=50)

Hi @Pernelle Marone-Hitz
It appears that the labels are not adjusting according to the deformation scale in this view. How can I ensure they are displayed correctly, taking into account True Scale Deformation?

s = DataModel.GetObjectById(73)
p = GRAPHICS.LabelManager.CreateProbeLabel(s)
p.Scoping.Node = 136

Hi @sombodyfromtheworld , I think this might be related to a Mechanical limitation in older versions. In 2023R2, the label does follow the deformation scale:

Thank you. Strange, I have the latest revision. Also none of this options are visible:

probeLabel.Note
probeLabel.Color

Hum, this is weird. Could you try turning on beta options?

Could you please point where I do change to beta?

Pernelle Marone-Hitz

Sure. From the WB project schematic, go to tools /option:

Then go to "appearance":

and scroll to find "beta options" and tick the box next to it:

Hi @Pernelle Marone-Hitz, thanks for tips.
Yes, I can confirm that it was an issue with the older release (I had actually 2023R1). Now I have installed a newer 2024R1 and it worked.

Can I also get your attention, how to only display a dot without any Label info.

Pernelle Marone-Hitz

Hi @sombodyfromtheworld , this example is to create labels. These can be scoped to nodes. What you seem to want to do is create some sort of drawing (ie, a circle). What you would need is to explore the Graphics API. There are some examples available:
https://discuss.ansys.com/discussion/2264/draw-an-arc-and-a-circle
https://discuss.ansys.com/discussion/395/how-to-use-the-graphics-api-to-draw-objects-for-example-a-line
However I don't think these graphics objects will follow the deformation scale factor.

There is no way to make a label text and lable line and fill to be transparent?

Pernelle Marone-Hitz

You could try to play with probeLabel.Color = Ansys.ACT.Common.Graphics.Color(red=240, green=0, blue=0, alpha=50) where alpha will be transparency.

Hi! Joining this thread with a similar question.
I am wondering how to do something similar to @sombodyfromtheworld. I attach the code and a picture for reference.

Code

active_plots = []
active_NSs = []

for ActObj in ExtAPI.DataModel.Tree.ActiveObjects:
if ActObj.GetType() == Ansys.ACT.Automation.Mechanical.NamedSelection:
active_NSs.append(ActObj)
else:
active_plots.append(ActObj)

for plot in active_plots:
Graphics.LabelManager.DeleteLabels(Graphics.LabelManager.GetObjectLabels(plot))
for NS in active_NSs:
probeLabel = Graphics.LabelManager.CreateProbeLabel(plot)
probeLabel.Scoping.Node = NS.Location.Ids[0]

Basically what I do is selecting two or more NSs containing a node reference and use this info to create labels in plots (this case is a max principal stress plot).
The tool works fine for 3D bodies. However, when having top and bottom plots showing 2D shell bodies, it always takes as reference the bottom plot position when providing a node number as scoping. In my case, this is not desirable, because stresses are way higher in the top plot position (see attached pic). I have not seen any attribute to change the plot position for label extraction from bottom to top.
I have thought of a workaround consisting of only reading both top and bottom stress values and comparing them using code before creating the label, but I don't know if that may be possible.
I would appreciate any help!
Thanks!

@AKD-Scripting-Team Could someone have a look at this one please? Thanks
