External parameters in assembly

Hi all
is it possible to link parameters to a notebook or excel in assemblies?
For example i would like to control the angles in this system of linkages (see picture) by changing values in a table.

Yes, layouts can be declared to assemblies and skeleton models. The main function of Notebooks is to define global parameters and then propagate them in a top down design. The example I posted above is used to drive multiple internal combustion engine architectures that employ skeletons, assemblies, and mechanism definitions.

 

With the notebook in session, open a part or assembly.
For a part, click Model Intent ▶ Image Declare. For a part or an assembly, click File ▶ Manage File ▶ Image Declare. The DECLARE menu appears.
Click Declare Nbk. A menu with a list of notebooks active in the current session appears.
Select the name of the notebook to which you want to declare the model. The model now references the notebook

    Turns out excel analysis is quite a good tool for a lot of stuff, thank you !

    You can use a Creo Notebook (.lay) file to manage the definition and propagation of parameters to models. You can declare and undeclare the layout to a given model to enable or disable the functionality. Tables are supported in Notebook files.

     

    This is an example of a Notebook used to control multiple parts and assemblies from a table.

    Yes but this only works for components doesn´t it?

    I can´t declare a notebook to an assembly and thus i can´t control its positoning nor is it possible to declare it to a motion skeleton.

    You can also create a drawing in Creo, build a table and add the parameters into the table to control the angles.

    Does this work with assemblies aswell? I know it works to control components but can you control positions in assemblies?

    Hi CreoCarlos,

     

    With excel it works fine, with these 2 cells I control angles:

    I changed the values, and regenerated the assembly:
