I can't for the life of me figure out how to make the Project parameters show up in my schematic template.

I have a variable string called =Title which I'd like to set in the project parameters, but it doesn't show up. I know I can set it up in Document parameters, but I want it to be in the project since its global to the entire project and not just the specific sheet.

Anyone quickly know how to set it up ?


The question may not have been clear.

In my schematic template, I have a string whose value is "=Title" without the quotations. I have gone to the Project Paramaters tab {Project-Project Options-Paramters} and have created a new paramter.

For the name property, I have called it Title and for the value I have called Test123.

What I expect to have happened was my special string to convert to Test123. It does not. I have changed the Name property to =Title and .Title and it still does not change.

If I change the Document parameters, I am able to change my special string into Test123.

Hopefully that's a bit more clear.

I figured it out.

You can't use any of Altium's stock/unchangeable Document parameters names in Project Parameters. So "Title" in Project Parameters will not supersede "Title" in Document Parameters.

Altium describes the process of implementing Global Parameters here: https://github.com/Altium-Designer-addons/scripts-libraries/wiki/AltiumPCBProjectTemplate

a. Create the global parameter (>Project >ProjectOptions >Parameters). Remember, try not to use standard altium parameters (e.g., CurrentTime, Date, Title).

b. In the PCBDOC, the parameter is expressed when you PLACE the following TEXT:

c. In the SCHDOC or SCHDOT, the parameter is expressed when you PLACE the following TEXT: =ParameterName


Go to Project-->>Project option

Window will appear with tabs.

Click on Parameters.

Here you can Add your parameters.

  • \$\begingroup\$ can you attach the picture of parameters that you are entering in the parameter column? \$\endgroup\$ Oct 1, 2014 at 6:05

A more elegant solution would be to evaluate the parameter at the project-level if its document-level value is not defined (empty). Unfortunately Altium does not do it.

The same can be achieved as follows:

  1. In your template add a parameter with the name 'Title' and value '=Title'. Save the template.
  2. Create a new schematic document based on this template. (If you are working with an existing document replace the old template with the new template. Due to a bug in Altium the new template's parameters will not be imported. You will do this by clicking Design>Update Template and choosing 'Update All Parameters' in the dialog.)
  3. In your project options create parameter named Title with the value Test123 (you already did that).

after you set up the schematic parameter, on the sheet add them by adding Text with the type. for example =author
