The Graphic Overrides are an important part of your View Settings when it comes to the View Map.
They ensure that the views represent correctly but applying a set of rules which change the drawing to suite what you wish to view.
To gather an understanding of how these work lets use a View as an example. This particular view is the GROUND FLOOR LIVING AREAS VIEW.
This view has the following view settings applied:
With these, it displays a simplified view of the Ground Floor Plan including all walls, some objects and some Fills.
These Fills are the ones we have drawn specifically to calculate Living Areas. We can also use these accompanied with the graphic overrides to crate a graphic such as this:
Let’s delve a little deeper into the settings to see how we achieved this.
We have drawn a bunch of Fills onto this particular Layer Combination: 190 – Living Areas. I have selected the large Orange Fill which represents the Living Area to show you the settings:
The areas found in the red boxes are the most important parts. These are the pieces of information we will use in the Graphic Overrides to produce the desired outcome.
With everything placed we can go into the Graphic Overrides Settings. Once opened we are shown a Dialog box like below:
You can see the layout is similar to that of the Layer Combinations where the combinations are displayed to the left and on the right are the rules which make up the combination, which in this case is what to show and how.
As stated above, we are going to focus on the 190 – LIVING AREAS overrides.
So we will select the 190 – LIVING AREAS Graphic Override on the left which displays the Rules of this particular combination.
The top two rules are generic rules which come as part of the AUSTRALIAN STANDARDS template which in this case, turn all cover fill backgrounds to white and turn all Cut Fills to transparent. You can see how this has worked as in the LIVING AREAS example above, as the cut fills in the walls are not showing.
The next few rules have been created just for this Graphic Override and apply to the various Living Area Types in this Project, in this case:
- Living Areas – Garage
- Living Areas – Living
- Living Areas – Alfresco
- Living Areas – Patio
Lets look into the Rules Settings of the Living Areas – Living Type. To access the rules you can select either the Ellipsis button or the Edit Rules… button.
Once selected you are shown the following Dialog Box:
On Left are the various Rules that have been created and on the Right are the settings.
The Rules work with 2 Main Settings:
- Criteria – what Elements need to satisfy before they are provided an Override Style as part of this rule.
- Override Style – What the parts of the elements will override if they satisfy the criteria.
So as can bee seen in the Graphic Override Rule, the element needs to be a Fill with an Element ID that contains the word FLOOR. In the project, our GROUND FLOOR Fill satisfies this criteria.
Once satisfied, the override styles will be applied. The Fill Foreground Pen will be changed to display Pen 39, a light orange colour.
We have done similar to all the other LIVING AREA TYPES by placing a criteria which must contain the certain ELEMENT ID before the override is applied. Then each LIVING AREA TYPE has a specific colour applied ti distinguish them from the other Areas.
The reason we have done it this way is so that there is only one location to drive the colour scheme for the LIVING AREAS. If you wish to change the light orange colour, you only need to go into the 190 – LIVING AREAS Graphic Override Combinations, then the Living Areas – Living Rule and change the pen colour of the Fill Foreground Pen option.
