We just upgraded to 2018 SP2. I have to rebuild after EVERY change to a feature. Change a dimension, rebuild, change, rebuild, repeat rebuild. It's getting really annoying. Previously if I change a dimension as soon as I hit enter on the new value, the feature changed. Example, have a 2" hole through a part. Double click the feature and I see the dimensions for the feature. Before, click the dimension, change it, hit enter the feature changed. Now I have to either hit the "regenerate model with the current value" icon in the dimension dialog box. Or hit enter, then hit rebuild. Solidworks already makes us make too many mouse clicks. Now they've added more. I for the life of me can't find where the automatic rebuild is turned off. TOOLS > OPTIONS > ASSEMBLIES > SUSPEND AUTOMATIC REBUILD is NOT checked. That is a setting for assemblies. So I don't know what has happened to parts. I went through one part and changed dimensions for 6 features before I noticed the features weren't changing. I saved the file. Went back to the assembly and then realized nothing changed. I hit rebuild then it changed. It didn't even ask me if I wanted to rebuild before I closed the file. It let me save it. Close it. I had another part I'd opened by itself and made changes. I opened the part and the features were like they were before the changes. I hit rebuild and it updated. Not happening automatically is really becoming annoying. I have to be missing something.
