Global parameters, across parts/assemblies

[mat_hijs]

I am about to make a lot of assemblies, they will be very similar to each other, all the principles will be the same, and so will a lot of parameters be. Problem is, these "global" parameters might still change over the course of the project. I don't want to have to open every single part/assembly and edit the parameters manually, this would take a long time, and mistakes would be garanteed. Would it be possible to compile a list of these parameters in an external rule or some other external file, change the values there, and run the rule in all assemblies to change all parameters at once?

I feel like this shouldn't be too hard with a simple Ilogic rule, but I have no idea where to start.

Hi Mathijs,

There are multiple ways to links parameters from one doc to another. You can use an Excel table with parameters to link to parts or assemblies. Or, you can use a part or an assembly with parameters and link them to other parts or assemblies accordingly.

These are one-direction workflows, meaning the parameters from Excel table or part/assembly drive parameters in other components.

If you want to manage the parameters all together regardless of components, you should use iLogic. In an assembly, create a rule at that level. In the rule, you have access to all parameters in any component within the assembly. You can write equations and drive one parameter from another.

Many thanks!

So there's no way to manage parameters across multiple assemblies?

Then would it be possible to create an empty part, just for the global parameters that might still change over the course of the project and link this part to all the top level assemblies?

Hi Mathijs,

Absolutely, you can use an iam file or ipt file as the master file. Store all driving parameters there just like in an Excel table. Simply open the part or assembly file you want master file to link to. Go to Parameters dialog -> Link -> select the master file. Those parameters will be linked and ready to be consumed.

Is this what you are looking for?

Many thanks!

Yes, this should make my life a lot easier. I can't believe I didn't think of this earlier. Thanks!
