Hello,
I found similar topic from year 2009,but I decided to open a new one since I was not able to repley to the old topic.

On my large piping file, I was able to run the analysis and get reports. However, when we decided to change the Load cases and re-run the software, it gave us an error saying that :
"Error 44E - Intersection Coordinate Mismatch exceeds the allowable"

Any suggestion?

thank you so much.

I've only seen a dimensional mismatch in the piping editor modeller error check, for which the only way this would happen is if you accidentally changed a dimension, cnode, etc.

Find your piping circuit(s) and increment one of the node numbers somewhere to see if the piping misaligns.
