IIs there any way where I can use the sketch from my skeleton model and use it in my part module. And also whenever I update my sketch in skeleton model same should get updated in my part module. Please suggest me on how I can achieve this. Thanks!
You can copy the sketch entities as curves into your part through a copy geom feature in the part. However, they come in as curve entities and are not recognized as a sketch that can be used directly in a feature. You'll need to create a new sketch or use an internal sketch in your feature that references those curves.
Once you've created the copy geom feature, it will update with changes to the skeleton unless you set it to independent.
