Roof Cricket Family

This section of the handout will give step by step instructions to create a variation on the roof cricket family.

1. Start with the OOTB GenericModelPatternBased template
2. Draw a point directly on top of adaptive point 2, making sure the Z work plane is used as the workplane
   • Start the Reference Point command
   • Use the Set Work Plane command
   • Tab to get the horizontal work plane on point
   •  
3. Select the recently placed point
   • In properties change the “Offset” value
   • Select the “Associate Family Parameter” button
   • Create a new parameter named “Rise”, and make it instance based
   •  
4. Draw a reference line between the newly created point and adaptive point 4, making sure the Draw on Face selection is highlighted and 3D is checked in the options bar
   • 
5. Draw a reference line from adaptive point 1 to the new reference point
6. Draw a reference line from adaptive point 3 to the new reference point
7. Draw a reference line from adaptive point 2 to 4
8. Set the work plane to be the horizontal plane of the diagonal reference line
9. Place a dimension from adaptive point 2 to 4 (make sure adaptive points are being selected)
10. Label the dimension with a new reporting parameter and call it “Run”
    • 
11. Open the Family Types dialog
12. Create a new instance based length parameter, label it “Slope”
13. Add the formula “(Slope*Run)/1”
    • 
14. Select three of the upper reference lines
    • Select the create form button
    • Select the surface option
    • Repeat for the other three upper reference lines
    • 
15. If desired, add a material parameter to the surfaces
