Need assistance with creating additional catagory parameters for both type and instance. The out of the box list of Catagory Parameters does not include enough choises.
Is shared parameters the correct way to make this work? I have had trouble in the past linking the shared parameters between the Title Block family and the Project its loaded into.
What exactly do you mean by "category parameters" ?
I think I understand what you mean. You are almost there.
In your Title Block you have added shared parameters?
When you place this titleblock on a sheet the shared parameters are not visible. This is because the properties which are available are from the sheet (not from the TitleBlock Family). You will need to make an addtional step.
In your project you have to add "Project Parameters" (under "Manage Tab").
In the window that is opened "Add"->"Family Parameter"->"Select Parameter" Select a family parameter that is the same as on your Titleblock Family, Assign it to the "Sheets" category. Repeat this for other parameters you have in your TitleBlock Family.
It is even advised if you add those project parameters to your template (if used in several projects) to avoid to repeat above steps with every new project.
