Revit Wisdom

“If you keep in mind that there are no shortcuts in Revit, you will work on doing things right at first and not have to "fix" them later”

                                                 … Some dude on the internet.

A colleague of mine came across these words of wisdom in one of the forums years ago, when we first started implementing Revit into our office. We thought it was so true and effective in its message, it found its way onto the cover of our office Revit standards guide. 
I thought I would post it today, as I continue to reference it when trying to help those struggling with the step by step approach often needed when using Revit.  

Solid White Fill Region vs Masking Region

What is the difference between solid white filled regions and masking regions?

That's the question I asked myself a few days ago when I came across a solid white filled region on a project. So with a little trial and error and some forum research I have pulled up the following.

Firstly, filled regions: Usually used for fill or hatch patterns, be it a brick hatch or a simple diagonal line hatch. This is not always the case and sometimes we create solid hatches, greys, black’s and colour if the need arises. (You will notice I didn’t say white! We will come back to that).
Filled regions also allow us to change the colour of the pattern and we have the choice between an ‘opaque’ and ‘transparent’ filled region within the type properties.
When we export our Revit drawings, filled regions are exported as hatch patterns.

*Masking regions are always opaque, we cannot make them transparent and you can’t apply a fill pattern to them.
Most importantly, when exporting out of Revit, masking regions don't create solids. If your masking regions use invisible lines, then they won't even export. Any lines that cross the masking regions will not show, maintaining the graphic appearance of the view. Draw order also comes into play. elements must be sent behind the masking region to be cut. 

In short, I would recommend using these particular tools for their intended purpose to save you hassle later. Masking regions to mask objects & filled regions for patterns / hatches.
