is it possible to set a model attribute as mandatory?

Hello David,

this topic has come up earlier In short: you can use an event triggered macro to check attributes or to start a semantic check profile. There is an example profile "Mandatory semantic checks" in which you need to specifiy your rules. Then it can be executed by a corresponding macro in the category "Automation".

But the downside of this approach is performance, as macros run client side, and breaking the flow of modelers, depending on which events should trigger the macro and if they are vetoable.
