Maximum number of expression dependency lists exceeded

3 posts / 0 new
Last post

I know this has come up on the list before but I am now struggling with
a (large, over-zoned) model that is throwing "Maximum number of
expression dependency lists exceeded" errors.

The archive suggested setting? MaxExpDeps=10 in the .pd2.? That does not
change the number of errors thrown on my model.

Would greatly appreciate assistance from anyone who has overcome this.

Many thanks,

Brian

Hi Brain,

This Error arises if you are using spreadsheet to input values in Detailed
Edit mode.
I would suggest you to input at zone & Space level and avoid using
spreadsheet for such over-zoned building models.

Warm regards,
Tejas

I came across this problem before.
As you pointed out, changing the MaxExpDeps didn't work for me.
In the end I deleted every interior wall to reduce the number of components in the model and it worked.
Not ideal but it was better than not running at all.
