Invalidated Extrusions after copy

[chip.cox]

I am probably going about this the hard way.  That seems to be the story of my life.  But here it goes.  

I have a design complete with text which extruded on the face.  I tried embossing it first, but had the same problem.  The first thing I do after gathering some information is use addNewComponentCopy to copy a template component containing the script I want to another sub-component off the root.  I do all my updates against this occurrence.  However after the component copy, the three extrusions of text are all invalid.  I have a loop for each character I want to change and they change on the sketch properly but are never reflected in the body.  I am assuming that is because the extrusion events in the timeline are invalid.  If I right click on each invalid timeline event and select edit feature, all I have to do is click OK and the sketch is shown in the body correctly. 

How can I make the extrusion or better the emboss events auto update as the sketch changes?

Or how do I determine invalid events and force them to re-execute.

Thank you

Can you post your model? I would like to test it to see if the same thing happens when you go through the same steps using the user interface or if this problem is specific to using the API.

If you run the "Compute All" command at the bottom of the MODIFY menu, does that fix the extrusions?

Here is my code.  It is my first attempt at a script.  It's even still named Hello World.  Please be gentle and don't hurt yourself laughing too hard.

Oh, and I forgot to add I got it to work by re-assigning the plane. Which is what I guess happens when I edit the extrude features in the time line. I'm just not sure if that's normal.

[BrianEkins · Accepted solution]

This seems to be a general Fusion problem and isn't specific to the API. You can easily see it if you select the "Template:1" occurrence in the timeline and choose "Copy" from the context menu. Now select the top node in the browser, and choose the "Paste New" command from the timeline. You'll see a new occurrence in the browser and also several new features in the timeline. The last three extrusions will be yellow. Running the "Compute All" command fixed those three but an earlier extrude changes to yellow. To fix it I had to open the edit dialog for the feature and click OK.

It will be good if you can report this on the Support forum. I wouldn't mention the API in your report since it doesn't have anything to do with the problem.

[chip.cox]

Will do.  It mostly works for now.  For some reason, when it exports the body to an stl file, it converts everything except the first letter to lowercase, which is a problem.  But I haven't played with it enough to know if it's my problem ( probably), a python problem on an API problem.

Anyway thanks for all your help.
