modeling or process mgt software free

Does anyone use a free modeling or process management software?
The commercial varieties are MS’s Vizio or Crystal Reports.
Cheap might also work.
I found on a free program called Bizagi that’s for business but is also at my price.

Actually, the only question asked was a boolean, so Norman went above and beyond :wink:

Yer right I should have replied “No” and been done with this thread

Like now

Thanks Norm. I should have also asked for recommendations

I use the desktop version and am happy with it. is good - I use it for chemical plant P&IDs, but it can be used for business diagrams
