View Display Rules - Example

View Display Rules can help you manage the Signal-to-Noise ratio of Big Data - without messing with level display (etc.)

Here's an exploration of Display Rules over a Simple QC Example (three True/False fields: Review, Fix, Fixed).

Prior to getting into the logic permutations of the fields and how the logic can be made visually obvious, I go over some data visualization concepts and some "which elements have item types" Display Rules, which are very useful.

Dataset:  Dataset--Item Types and Display Rules.zip

The *.dgnlib contains Item Types and Display Rules.  You'll want your ItemType and DisplayStyle configuration variables to pick this up (MS_DGNLIBLIST_ITEMTYPES, MS_DGNLIBLIST_DISPLAYSTYLES, respectively.  You can "cheat" by copying this file to the Feature Definition and the Display Styles folders.  

If you don't have permissions to write to the C:/ProgramData/Bentley folders, you can import the Item Types and Display Rules into your active file.  Finally, you can copy the dgnlib to a dgn and reference in all the relevant files.  That works.

The dgn's used are from Bentley's Training and Examples workspace, with some data additions to do it.  The videos use the Geometry.dgn file, but you can open any file and use the Display Rules to discover where the relevant features are (which is the point of the Display Rules!).

Overview

Our platform is getting busy.  Everything can be shown.  All at once.

Can we manage all the new noise in the system?  How do we not get overwhelmed?

How can Display Rules Help my Project?  How can they help me Communicate?
