I saved some personalized styles in a project and don’t know how to use the same styles in a new model.
You can save the In Model styles as a local collection. Choose In Model and then open the Details menu (to the right of the drop down window) and select Save collection as…
You can also open the secondary pane of the Styles panel, set it to your desired destination collection and then drag and drop the style thumbnails from In Model to the secondary pane. This works exactly the same way as it does for components and on Windows, for materials.
Thank You DaveR!!!
