Trying to create an equation in the top level assembly that updates other files

Mattew Stafford Mar 28, 2017 12:45 PM

1. I have an expression in my top level assembly called "Tail Pulley Diameter" with a value.

2. I have a part in that assembly with a sketch. I created a global variable in that part called "Tail Pulley Diameter" and for the Value/Equation column, with my assembly open, I selected the "tail pulley diameter" value in my top level assembly.

3. When I open the part, I get an out of context message.

What might I be missing?

There is probably a better way, but I would do it this way:

Export your variable from the top level assembly:

Then save it as a text file.

At the part level, import the text file:

Now, you can update the text file if you need to change the dimension and it will drive both of them.

  Thanks for the reply. I may have to look in that direction if I can't figure out why the message shows up. Oddly enough, it still updates with the change to the variable at the assembly level, but the message still shows up. I am a bit new to equations in solidworks, so I figured I was not doing something correctly. I think the external file may not work well with our workflow, but its hard to say.

Do not open the Part linked to top level independently. Open the Part-in-Assembly.
