Creating Terraces in Revit

A level terrace site is often created in Revit using floors and walls. However, there is a better way to do this - After all, we would like to determine the cut and fill, don't we?

The image below depicts the finished terrain, complete with gabions. Let's see how we can achieve this result.

First of all, lets go through the basic setup of our topography. I love reference planes and therefore we need to create vertical and horizontal reference planes to guide us in the section of topography we want to work with. This site will step down 500mm every 1000mm.

You will notice however, that we cannot place toposurface points with different elevations exactly above, or below each other.

An easy fix for this is to move the lower or higher toposurface points with 0.8mm horizontally to create the terrace

 Creating and placing simple gabion families finishes the terrain off nicely.

Have a great week folks!

Revision Numbering: Clearing the Confusion

Revisions per Sheet or Revisions per Project? That is the question.

There is a misconception with Revit's naming convention for revision numbering options. People often believe that if the revision numbering is set to Per Project, all sheets in the project will have the same revisions showing, irrespective if the revision is applicable to a specific sheet or not. This is not the case at all.

As illustrated by the images below: If the revision numbering is set to Per Sheet, when hiding a specific revision on a sheet, all other sequential revision numbers will change to follow one another. 

However, if the revision numbering is set to Per Project, the revision numbers will not change, thus all sheets will remain in the sequence it was issued with the correct revision numbers.
