Highlight

Mod-Roof > Highlight

This command draws a highlight plane along a ridge as well as offside plane if you wish. It also modifies the offside roof plane by cutting a hole.

After selecting the command, you then click on the ridge you want to modify. Since each ridge can be connected to 2 planes, you are then prompted to determine which plane to extend the highlight plane from. You do this by clicking yes or no to the message dialog box which appears.

This message asks you “Do you want to extend from this plane?” and flashes the boundary of the plane for reference. If you want to extend from the offside plane, then click No.

After you have done that, the Highlight plane defaults dialog box is displayed allowing you to set parameters for the highlight window.

Distance Along Ridge This is the distance the highlight window will start from the end of the ridge you selected. For you reference, that particular end begins to flash.
Highlight Width This is the width of the highlight window
Highlight Depth This is the depth of the highlight plane
Side Overhang This is the amount the edges of the highlight plane will overhang the resultant hole. If you enter zero (0), the edge of the highlight plane matches the resultant hole.
Gable Overhang This is the amount the front of the highlight plane will overhang the hole
Offside Plane Depth This is the depth of the offside plane. If you set this value to zero, there will be no offside plane.
Pitch Offside Plane This is the pitch of the offside plane. The default value is that of the offside roof plane.

Once you click [OK], the highlight plane is drawn together with the offside plane (if you want one) as well as a hole in the offside roof plane.

Note: If you don’t want a hole to be cut, then set the sum of the highlight depth and the offside plane depth to be the same as the verge overhang ie if (highlight depth + offside plane depth = verge overhang) then no hole is cut.

The following diagrams show highlight windows without an offside panel, then with an offside panel.

Here you can see the highlight panel in isometric.

This highlight window has an offside panel.

Here is a highlight window with an offside panel in isometric view. You can see the ridge in the highlight roof section as well as the hole, automatically created.
