Where does Fusion store property values shown in the post dialog?

When posting we have the option to set post property values. If you change a properties' value, then post, and then post again later, the value you set for the property will have been "remembered". Where is Fusion storing this information?

As an example, in the picture below I'm using the Haas NGC post config "haas next generation.cps". I checked the "Use chip transport" box, and after posting I find the registry key "HKEY_USERS\Software\Autodesk\Fusion 360 CAM\post configurations\user://haas next generation.cps" has a new value named "gotChipConveyor" with a value of "true". This looks to be exactly what I want, but I find that Fusion isn't reading the registry key to populate the property values in the post dialog. I.e., if I modify any of the property registry keys, the properties shown in the post dialog don't reflect the modified values.

The goal is to be able to programmatically change post config properties. FWIW, what I'm trying to do in Fusion already works great in HSMWorks which uses the registry for both writing AND reading post property values.

Hi,

The custom parameters for the postProcessor are defined at the beginning of the postProcessor file, as within the following example:

... // user-defined properties properties = { writeMachine: { title : "Write machine", description: "Output the machine settings in the header of the code.", group : "formats", type : "boolean", value : true, scope : ["post", "operation"] }, ...

The very first value is defined in that code snippet with the "value" property, but I don't remember there is some definition on how it is kept since its first use.

Once you generate a NCprogram the values of each property are kept inside the NCprogram.

Notice you can have the property defined from the operation or from the postProcessor, according to the "scope" property.

I hope this can help somehow.

Regards,

Maybe my question wasn't clear. What I'm concerned with is the post dialog screen shown in the picture in my original post and where it is obtaining its property values from. To help clarify, below is a step by step process with pictures. To keep things as simple as possible, the example below uses the same property I used as an example in my original post; the "Use chip transport" property. Though the "scope" of the property doesn't matter for the post dialog, this property's "scope" is "post" as seen here:

gotChipConveyor: { title : "Use chip transport", description: "Enable to turn on chip transport at start of program.", group : "configuration", type : "boolean", value : false, scope : "post" },

1.) Press the "Post Process" button in the Fusion tool bar to open the Post dialog:

2. ) Note the value of the "Use chip transport" property and press "Post". The NC file will be generated and the Post dialog will close:

3.) Press the "Post Process" button in the Fusion tool bar to open the Post dialog for a 2nd time:

4. ) Note the value of the "Use chip transport" property:

5.) Change the value of the "Use chip transport" property and press "Post". The NC file will be generated and the Post dialog will close:

6.) Press the "Post Process" button in the Fusion tool bar to open the Post dialog for a 3rd time:

7. ) Note the value of the "Use chip transport" property:

This process shows that the Post dialog retains whatever setting was used the last time. My question is, where is Fusion storing that information? As I mentioned in my original post, HSMWorks writes AND reads this information to/from the registry, but Fusion only seems to write the information to the registry because modifying the registry values then attempting to post doesn't change the value displayed in the Post dialog.

If you observe the registry while following the process I outlined above, you will see this when "Use chip transport" is not checked:

And you will see this when "Use chip transport" is checked. Note the "gotChipConveyor" entry:

But again, Fusion is NOT reading the values shown in these registry pictures to populate the Post dialog, so where is it reading the values from?
