ADVANCED AURORA MODELING
Design
To design a good layout, we need to be equipped with tools and methods that allow for accuracy and best practices for installation. This training will cover the basics with some hands on activities to practice.

COMPLEX CONTOURS
COMPLEX CONTOURS
Here's one that is seen pretty often. When you have odd shapes such as hexagonal roofs follow this guide to help you:
Make a dormer that is the approximated size. Then convert to roof.
next, delete one of the corner nodes. This will allow you to draw additional nodes where the obtuse angles should be.
At first, you should draw the nodes level with the furthest eave.
then you can move these nodes back into the correct position and adjust the pitches to fit the correct contour.
LARGE COMPLEX ROOF STRUCTURES
LARGE COMPLEX ROOF STRUCTURES
When modeling large and complex roofs, it is sometimes better to think of the structure as many smaller and simpler roof structures for the purposes of modeling.
Start by identifying a good base for the model:
All other roof surfaces can be built onto the base model.
Look for ways to hide “rough edges” of the base model under the other pieces of the model to be built later.
Remove unwanted roof sections
Adjust roof section pitches
Raise / lower roof sections to line up ridgelines, hip / valleys, or other roof edges in order to match the aerial imagery.
Adjust perimeter heights and locations:
This will relocate select hips and valleys without shifting others across the whole model out of corners and eliminates having to manually adjust all hips and valleys
Add other aesthetics to the modeled roof sections, such as Roof Folds
Create additional roof sections by building dormers:
Convert to roof ensuring the new roof structure is perpendicular to the base model.
Add flat dormers to complete the model

TRY IT YOURSELF
Make sure to create a new design space in aurora to practice in. Try to make a judgment on roof pitches using the site survey located in sales force for this project.
Once completed, have your supervisor QA the model!
EFFICIENCY OF MODELING
EFFICIENCY OF MODELING
One thing to remember:
Some modeling challenges are not worth tackling. Only worry about accuracy on roof planes we’ll be mounting on.
Get the model to a state where it can be corrected to look correct on the plan set DXF.
The example on the below is perfectly acceptable.
Another Example: This model view is oriented true north for reference.
Based on the orientation and overall area of roof available, the roof section with the green boarder highlight has been selected as the best roof mounting plane.
The Designer only needs to ensure that this roof section is rendered 100% correctly if this will be the only roof with PV on it.
Note that if there are more roof sections with PV, we also need to ensure full 100% accuracy with these roof sections as well.
The accuracy of a roof like this where there is a single ridge will still depend on symmetry with the dimensions of the roof on the opposite side of the ridge.
The areas in purple represent the measurements that need to be checked. against each other.
The designer also needs to give special care that the intersecting dormer is occupying an accurate amount of area.
Pay attention to image skewing (as applicable)
Only worry about obstructions on this dormer if you will be mounting on it.
The area across the ridge doesn't need to be that accurate because we aren't planning to mount there.
You should still design the entire roof area approximately, but don't worry as much about accurate dimensions on dormers or obstructions on roofs that will not be occupied with PV.
Let’s try another complex model:
Make sure to create a new design space for yourself to practice on. Utilize Lidar to make judgments on roof heights and pitches.
