The following is a description of the Nominal Sizes and Tolerance page of the Graphical Interface Panel of Window Settings, for a window in the INT ArchiCAD Library.
Window size (height and width) can be defined with respect to any of three types of dimensions: Wallhole, Reveal or Unit dimensions.
The numbered graphics help you identify the dimensions.
Wallhole Dimensions
The Wallhole is the part cut out of the wall to accommodate the whole window structure.
Wallhole Width is equal to Unit Dimension Width plus any Horizontal Tolerance.
Wallhole Height is equal to Unit Dimension Height plus any Vertical Tolerance.
Reveal Dimensions
The Reveal Dimensions measure the width/height of the window opening between the reveals. If no Reveal is set for this window, these dimension fields are grey.
•Use the Reveal Settings tab page of the Graphical Interface Panel to choose a Reveal and its settings.
•You can also choose a Reveal Type from the General Settings tab page of the Graphical Interface Panel.
Unit Dimensions
Unit Dimensions are the width and height of the whole window structure.
Set as Nominal
Use the Set as Nominal radio button to choose one of these dimension definitions as the window’s Nominal Size.
•This is the Nominal dimension that will be listed in the Interactive Schedule in the Nominal W x H Size field.
•This Nominal dimension will be displayed in the Width and Height fields in the Preview and Positioning Panel or Window Settings.
Retain Nominal Size on Change: This checkbox is applicable if you change your definition of the Nominal Dimension (e.g. from Unit Dimensions to Wallhole Dimensions). If this box is checked, then the values of the original Nominal Dimension (those set for Unit Dimensions) are transferred to the new Nominal Dimension (your Wallhole Dimensions). The other dimension values will be adjusted automatically.
Show Dimensions in Window Marker
If you display a window marker, use the Dimension Marker Panel (Marker Options - Size to Show) to choose one of these dimension definitions (Wallhole, Reveal or Unit Dimensions) as the preferred dimension to display in the marker.
