How do I force Mathcad Prime 3 to recalculate worksheet using command line or maybe some document property?

[yrereq]

I've installed a DLL with custom functions and it appears undefined to worksheet until I recalculate.

For example, Mathcad was compaining what CustomFunctions variable is undefined even when I managed to install DLL properly, only when I did Ctrl+F5 CustomFunctions reflected the actual state of things. And if I close Mathcad and deinstall DLL, opening the same document will prentend it is still there (again, old infromation shown until recalculated)

Is there a way to have Mathcad to not cache previous data and recalculate whole document on open?

This begaviour was, as far as I know, implemented un purpose to reduce loading time. Without it Prime Express wouldn't be able to show worksheets containing "premium" features.

I guess there is no way to change it and implement an auto-recalc.

It is caching the worksheets and information is my guess. Disable the cache in the Input/Output tab.

No, this options has nothing to do with the effect discussed here. It only affects included/referenced other worksheets.

Hello, gentlemen. Thank you for the input.

I finally figured out rather crude but working solution

@ECHO OFF
REM Uses InfoZip syntax
ZIP -d %1 mathcad\result.xml

this removes a part of specified OpenXML file (denoted by %1), effectively invalidating the whole document.

Yes, but is doesn't force a recalculation of the worksheet on startup. Plots are blank and evaluations are shown as question mark. But at least you don't see any (wrong) old results that way.
