Deep Space stores historical information about your project models, including quantities like Count, Area, Volume and Length.
The Variations App gives you a side-by-side comparison between two different 'data drops', or points in time.
This can be used to compare quantity changes between Tender models and current For Construction models (for example).
Generally, the Variations App needs the following:
Two 'data drops' created
The relevant 'data drops' are set in DS Command against the Project
Refresh the dataset
This article describes how you can work with Data Drops in Deep Space:
In a previous version, Variations app used a mixture of parameters that were stored in a global schema eg.
SELECT vbgp.parameter_name FROM global_params vbgp
WHERE vbgp.used_for = 'Quantities' AND vbgp.sub_type = 'Area';
For performance reasons, the above functionality has been put on hold. Currently, variations app uses these parameter names:
