Project Altitude dependent parameters

[Arnaut_2604]

Hi there,
I'm trying to use a parameter which depends on the project altitude for a manhole.
So the Entry Parameter would be E.
E1 is the height to project 0.00

E2 is the same height but in reference to project altitude.

Reason being that I'm combining several sewerplan's from the past 40 years into one plan. They all have different project elevations.

For example elevation is 1000m

if

E1 = -10

E2 = 990

So

E1 =  -GLOB_ELEVATION

E2 = GLOB_PROJECT_ALTITUDE -GLOB_ELEVATION

Now my problem is that GLOB_PROJECT_ALTITUDE seemingly can't be used to influence parameter values.

Is there a way around this?

GLOB_PROJECT_ALTITUDE can not be used in the parameter (master) scripts.

So you can't set a parameter from it.

But you can use it in the 2D script.

Thanks for the quick reply Barry.
I guess there's no work around for this?

Could you Request Story_Info to get your story elevation then add it to ZZYZX?

This would only give me the elevation in relation to the project to altitude unfortunetly.

Add a Request Reference_Level_Data to get your sea level reference?

I hadn't thought of that actually. Works brilliantly! Thanks so much
