General project information includes basic information about the project, such as project's name, description and target information. This information is updated to drawing frames and labels.
Project settings, in turn, affect the appearance of drawings and ways of marking, and can be a very important part of the project. The settings are grouped so you can only keep visible those groups which in most cases will be changed in various projects.
Default project settings can be modified in order to set project settings correctly right from the start. With the Default settings button, you can edit the project default settings that will be assigned to new projects.
