Hello everyone,
So Fusion behaves very weirdly when you try to cause the Execute Preview event from a custom event, everything happens seemingly without issue, but if a fillet (and probably other features) has an error, then the fillet features of the component become "broken" and don't work anymore. This problem doesn't occur when using a separate thread to trigger that event. I the code below I have a test figure that first creates itself normally and then, when the preview event is called again either through a separate thread or a custom event, creates itself with a value for the fillet too big for it to work. Then it gradually reduces this value until it can be created. However, when the preview is caused by a custom event, the first error causes a problem with the fillet features and the creation fails altogether.
Honestly I have absolutely no idea what could cause this. Does this also happen on other machines (simply change threadMode to True of False to test both possibilities) ? Does anyone have any idea what is actually happening here ?
