I'm trying to change the default preferences for sysml blocks (and others nodes) by using the preferences window but can't find such an option. My version of eclipse is Neon.3 Release (4.6.3), my version of papyrus is 22.214.171.124703080851, and I have the sysml 1.1 and 1.4 versions installed. Attached is an image of where I expect to see such preferences. Note, I know they exist because the sysml youtube tutorial at the 1:50 time mark (youtube.com/watch?v=jj0e3fHQK7Q) shows them. Pls help.
The support of preferences has been replaced in the last versions by CSS and other configuration support, that are easier to share with others. I invite you to read the following wiki page in order to understand this support and find the options you want to get.
