Multi-Hip

This command lets you insert a multi-hip roof. You can use this command for towers, spires and bay windows. You are first prompted to locate the apex point of the hips. When you have done that, the Multi-hip defaults dialog box is displayed.

Number of segments
this is the number of equal length segments to create. The minimum number is 3.
Radius
this is the horizontal distance from the center of the tower along a hip.
Sweep angle
this is the total angle you want the multi-hip roof to sweep from the initial direction you digitised around to the final hip in an anti-clockwise direction. For a circular tower or turret, you would enter 360 degrees.
Ridge extension
You can force a gable or hip end to project from the multi-hip by entering a length for the ridge that would project from the apex of the multihip. This has no effect for a 360 degree sweep angle.
Rotation angle
Here you specify the angle to rotate the multi-hip clockwise from the current y direction (unless you have changed it, then it is to the right of the screen) around the z axis (out from the screen).
Preview
Here you can preview the shape of the multi-hip and alter its shape and size before committing to it.

When you click [OK], the multi-hip roof is drawn.  The multi-hip roof is drawn similar to that below.

In isometric view, this multi-hip roof would appear like the following.

Note – These Multi-hip settings give you the ridge and if selected, a gable end, as shown below.  Note that we have set a ridge length and that the sweep angle is set to 180 degrees to achieve this geometry.   All the roof planes around the multi-hip are the same pitch, but don’t necessarily meet at the apex of the ridge.

If you need to have all the hips join at the one place, you will need to use the Group > Stretch function after this has been constructed and, following the prompts, middle button ‘snap’ to select the lower apex, and then middle button ‘snap’ the higher apex to place it.   The hips will all be stretched to the new location (and the pitch of each plane will vary slightly).
