3D Molding Polyline Specification Dialog

Select a 3D molding polyline and click the Open Object

edit button to open the 3D Molding Polyline Specification dialog.

General Tab

Uncheck Molding on Selected Edge to turn off the display of the specified molding on the edge of the 3D molding polyline that was selected when the dialog was opened. For more information about the selected edge, see "Selecting Objects".

When Automatic Frieze is checked, the frieze molding is updated whenever you check Build Fascia, Gutters on the Build Roof dialog and click OK.

Once Automatic Frieze has been unchecked, it cannot be checked again.To restore the automatic updating behavior of the frieze molding, it must be regenerated. See "Creating Frieze Moldings".

Selected Line Tab

The Selected Line tab is available when the selected segment of the 3D molding polyline is a line as opposed to an arc.

The Length/Angle section in the 3D Molding Polyline Specification dialog is different other Selected Line tabs.

Length specifies the 3D length of the selected line of the 3D molding polyline.

Angle in XY Plane specifies the counter-clockwise angle that the selected line makes with the positive X axis when viewed from above, as in floor plan view.

Angle from XY Plane specifies the angle that the selected line makes with the horizontal XY plane when viewed from the side, as in a cross section/elevation view. A positive value means that the line slopes up; a negative value means that it slopes down.

For more information about using the Selected Line tab, see "Selected Line Tab".

Selected Arc Tab

The Selected Arc tab is available when the selected segment of the 3D molding polyline is an arc as opposed to a line.

Select Start to keep the start and center of the arc fixed and move the end.

Select Center to keep the center of the arc fixed and move the start or end.

The Start options specify the coordinates of the starting point of the selected arc, and are editable when either Lock End or Lock Arc are selected.

The End options specify the coordinates of the end point of the selected arc, and are editable when either Lock Start or Lock Arc are selected.

The Chord options specify the length and angle of the selected arc and are editable when either Lock Start or Lock End are selected. The Chord Angle is also editable when Lock Arc is selected.

Chord Length - the 3D distance between arc start and end.

Chord Angle - the angle created by the arc chord and the positive X axis.

The Arc options specify radius, angle and length values of the selected arc:

Radius - the distance from the arc to the arc center.

Start Angle - the angle created by a line from the arc center to the start and the positive X axis.

End Angle - the angle that a line from the center to the end

Arc Angle - the angle created by a line from the arc center to the start and a line from the center to the end.

Arc Length - the length of the arc.

The Center options specify the coordinates of the center point of the selected arc and are editable when Lock Arc is selected.

The Normal options specify the coordinates of the normal for the plane that the arc exists in. The normal is a vector that is parallel to that plane and is expressed as a line between two points: (0,0,0) and the point defined in the dialog.

In plan view, the arc direction is counter clockwise if the normal has a positive value on the z axis (0,0,1) and clockwise if the value on the z axis is negative (0,0,-1).
