A cricket must be created in a roof design that needs adjusting to help facilitate the shedding of water and/or snow. In Envisioneer, we will create the cricket using surfaces and add it to a parallel gable roof design.
First, we need to know the height of the fascia board. We do this by opening the roof’s properties by double-clicking on one of the fascia edges.
1. Select the roof, right-click and select Properties.
2. The properties show that the e-Fascia Distance is set to 8’ 5/8”. Let’s copy this value by highlighting it and then pressing CTRL + C on the keyboard.
Now that we have the Fascia Distance value, we can map out exactly where we want the roof lines for our cricket to be.
3. Type L on your keyboard or select Tools > Layout > Line. This will open the line command.
4. Move your cursor over the middle of the left 25’ wall and then left click to start your line when you see the Circle with an X.
5. Move your mouse to the right and left again when you snap to the middle of the 25-foot wall on the right side.
6. Right click and select Finish.
We have now established where our ridge line will be for our cricket roof.
When the Parallel Gable roof was created, we established drafting lines to mark the edges of the fascia. We are going to use these lines once again to help create the fascia of our cricket roof. These lines were created by offsetting a center line 1’-4” to the left and right.
We now need to mark out the ridge lines of the Gable roofs so that we have an intersection to snap to.
7. Select one of the vertical lines showing where the fascia of the gable roof is located, right-click, and select Duplicate.
8. Left-click on the end of the line, move your mouse over it and snap it to the ridge of the gable roof.
9. Duplicate the inserted line over to the opposite gable ridge.
These new lines are going to be our guidelines for creating our roof surface.
10. Select the Surface button or go to Insert > Surfaces > Surfaces.
11. Select the Asphalt Shingle Roof Surface from the catalog on the right.
When creating a surface, the Fascia Edge should always be established first, as this denotes where the roof surface slope starts.
12. Left-click on one of the vertical lines representing the Gable Roof Fascia.
13. Move your cursor over and select the opposite line that represents the other Gable Roof Fascia.
This creates our cricket fascia, and the surface will slope up from here. Now, we need to snap the surface to the intersection of the gable’s ridge and the ridge line we added.
14. To do this, we will need to disable ORTHO. You can do this by pressing F8 on your keyboard or by selecting the ORTHO option in the lower right of the Commander.
15. Now, left-click at the intersection to create our angled roof surface line.
16. Move your cursor to the right and snap to the opposite ridge line intersections.
17. Right click and select Finish and the Define Surface dialog will appear.
18. We are going to make the Slope value a 3/12 slope and then lock that value in by pressing the lock button. This ensures that any changes we make to the upper or lower points will not affect the roof slope.
19. In the Lower Point option, we will paste the 8’ 5/8” distance we copied earlier by pressing CTRL + V on our keyboard.
20. Press OK to close the Define Surface dialog.
We now need to move the surface fascia so that it meets up with the edge of the gable fascia.
21. Select the surface we just added and then stretch the fascia edge down to meet the gable fascia.
22. This will also lower the fascia distance, so we need to adjust the Surface Arrow. Select the hollow blue grip of the arrow and stretch it to meet the fascia we just adjusted.
23. With the surface still selected right click, select Surface Commands > Define Surface.
24. In the Define Surface dialog, we will again lock the slope at 3 and paste in the 8’ 5/8” value in the Lower Point. Press OK when complete.
25. This creates the sloped surface at the correct height for us, but we still need to adjust the sides of the cricket roof as we are combining two different sloped roof surfaces. In this example, the gable ridge lines need to be offset by 3’-6”.
26. Select the surface and snap the hollow blue grips to the new line intersections. This allowed the cricket edges to align with the gable roof without extruding into the surface.
27. We have created the first cricket surface, and all we need to do now is mirror it to the opposite side. Make sure you have enabled ORTHO by pressing F8 or by selecting ORTHO in the commander. Select the surface that we have created, right-click, and select Mirror.
28. Left-click on the endpoint of the surface that represents the ridge and then move your mouse to the left or right so that the surface mirrors around that point the surface is visible on the other side, and the left-click again to insert it.
29. When prompted, we do not want to delete the original surface, select No.
This creates the cricket roof between our Parallel Gable Roofs. You can view the model in 3D to better see our new roof design.
