The document provides step-by-step instructions for creating a window family template in a building project with adjustable width and height parameters. It describes creating reference planes, extrusions, and dimensions for the window frame and glass, locking elements to reference planes, setting thickness parameters, and assigning materials.

1. Figure 63 load the family into project
Building elements (casement window)
Figure 64 Open new window family template

2. Figure 65 release lock parameters for width and height. set both as instance parameters
Figure 66 create reference planes for window frame

3. Figure 67 create extrusion for window frame. lock it to reference plane
Figure 68 set and lock dimension for reference plane of window frame.

4. Figure 69 create parameters for window opening
Figure 70 create reference plane for window frame opening

5. Figure 71 create extrusion for window frame. lock it to reference plane
Figure 72 set and lock dimension for window frame opening

6. Figure 73 create reference plane for window frame thickness
Figure 74 move and lock window frame opening to reference plane

7. Figure 75 create and lock glass extrusion to reference plane
Figure 76 create reference plane for glass thickness

8. Figure 77 move and lock glass thickness to reference plane
Figure 78 create and lock dimension to reference plane

9. Figure 79 create material for glass
Figure 80 create material for window frame using instance parameters
