Manual Roof Planes

[twnctyguy]

Simple question...what is the added line (see picture attached)?  Not sure what purpose it serves and I can't seem to delete it.  Thanks

 

I'm using Chief Architect Premiere X13

It's the roof baseline. Just turn off that layer.

You might also want to read up on it before you just go ahead and turn it off and make sure it is correctly positioned first.

The roof baseline, when generated by CA is located above the outer plane of the wall's main layer.  

(from the CA Help File)

Editing Roof Baselines
The pitch direction and initial height of any roof plane - manual or automatic - is determined by its Baseline. See The Baseline.

In plan view, a Baseline can be selected and edited independent of the roof plane. To select it, click on the roof plane at the location of the Baseline and then click the Select Next Object  edit button. The Status Bar tells you when the roof plane Baseline is selected. See Select Next Object.

If a roof plane Baseline is moved, its height will not change. Instead, the height of the roof plane will be affected. In most cases, therefore, moving a roof plane’s Baseline independent of the roof plane itself is not recommended.

If the angle of a roof plane’s Baseline is changed, the direction of the roof plane’s pitch will be modified. The Baseline Angle can be modified in either of two ways:In the Roof Plane Specification dialog. This will change its angle relative to the floor, and will tilt the roof plane along an axis perpendicular to its Baseline. This method is helpful when a specific eave angle is needed. See General Panel.
Using its Rotate edit handle in plan view. This will change its angle rela
tive to the roof plane’s eave or ridge and will modify the direction of the pitch. This method is best when the pitch direction matters more than the angle of the eave.
Both of these methods can be used to modify the same roof plane, although the second approach makes it difficult to control both the pitch direction and eave angle, and is not recommended.
The length of a roof plane Baseline can be lengthened or shortened using its edit handles without changing any of the roof plane’s attributes.

 

 

This is from a test file that I used to auto generate roof planes, then the edit roof DBX

 

The roof BASELINE seems to be the place where the outer plane of the wall main layer intersects the top edge of the roof rafter when using conventional framing.

 

Moving the baseline by editing WILL CHANGE THE ENTIRE LOCATION OF THE ROOF PLANE!  This means that all of the intersections of the roof valleys, ridge intersection and fascia height for that plane will be changed.

 

This is just a heads up that changing the location of the baseline may have unexpected results in the roof structure.  

 

It may be easier to delete the plane, and then draw a new roof baseline over the bearing wall, then editing intersections using the join roof planes tool.
