Linear Dimension Tool Settings

Dimension Type: Define how you want to calculate your linear dimension.
With the Linear method, distances between two adjacent Reference Points are measured and displayed.
With the Cumulative method, the first Reference Point is considered the zero point of the dimension chain. All dimension values of the chain will give you the distance between any Reference Point and the zero point.
With the Base-line method, measuring the dimensioning distances is the same as with the Cumulative method, but the zero point is not marked.
With the fourth icon, you create Elevation Dimensions.
Witness Line: Click one of the radio buttons to define the Witness Line format.
Note: Length of Custom Witness lines is set below, at: Dimension Marker and Witness Line Options Panel.
Note: The gap between the Witness Line and the dimensioned element is set below, at: Dimension Marker and Witness Line Options Panel.
Arrowhead for Pencolor/Penweight: Type a Pencolor/Penweight number (1-255) here for the Arrowhead marker.
Hint: For thicker Dimension Arrowheads, use a Pencolor with a heavier Penweight (defined in Options/Pens & Colors).
Dimension Line Pencolor/Penweight: Type a Pencolor/Penweight number (1-255) here for the Dimension Line.
Font Type: Click this pop-up field to select a font for the Dimension Text.
To the right, select a Pencolor and Pen weight for the Dimension Text.
Font Script: Click this pop-up field to select a font encoding for the Dimension Text.
Font Size: Enter a font size for the Dimension Text here. Note: Fractional sizes are allowed, but may be rounded.
Text Format: If desired, check the Bold, Italic, or Underline boxes to format the dimension text accordingly.
Horizontal Text: Check this box to display dimension text horizontally. (This is the default setting when the 3D Document window is active.)
Opaque: Check this box to set a background color for your dimension text block and activate the pencolor selection settings at right: open the pop-up menu to choose a color. The pen of this Fill may also be set to 0 (Transparent) or -1 (Window Background). Henceforth your text editor will also have this background color.
Frame: Check this box if you want the dimension text block frame to be visible. Checking the box activates the pencolor selection settings at right: open the pop-up palette to choose a color for the frame.
Marker Size: Enter the size of the marker here.
Dynamic Witness Line Gap: Enter the element-Witness Line gap value here for the Dynamic Witness Line.
Custom Witness Line Length: Enter the length of the Custom Witness Line here.
Note: Even if you have not turned on a Pointer Line for a Dimension text, a Pointer Line will automatically appear if you drag the Dimension text box beyond a certain range.
Define a Line type and Pencolor for the pointer line.
Enter the Pointer Starting Angle using a value from 0 to 90 (the default is 90 degrees). The angle is measured from the dimension line. Click the lock icon to prevent the angle from being modified graphically (e.g. by accident).
Note: The Lock Angle control affects the range of graphical editing. If it is ON, the Pointer Line’s starting angle remains fixed, limiting the edit possibilities.
Hide Arrowhead from: Check this box if you want to hide the pointer line arrowheads on views which exceed a certain scale (enter the desired scale in the field to the right).
The Dimension Details panel contains options for the dimensioning of Windows and Doors and composite Walls.
Note: These controls are in addition to the options available through the Dimension Marker panel of the Door/Window Settings dialog boxes, and works for both smaller and larger sizes for German type reveals.
Display the Height of Openings as well: Check this box if you want the dimension marker to display the opening’s height value along with the width. If you check this box, choose one of the three radio buttons at right to define how to display the Height value:
Dimension only the Core of Walls and Slabs: Check this box to dimension core thickness only for Walls and Slabs. Core dimensions are associative.
Note: These options are available if the dimension type is set to “linear” (not cumulative, baseline, or elevation). (See Dimension Type and Font Panel.)
Classic: The algorithm used in older versions of ARCHICAD.
Allow below dimension line: As part of the adjustment, texts may be displayed below the dimension line as well as above.
Allow adjacent texts to shift: When a dimension text is shifted sideways, its adjacent dimension texts may also shift sideways (to the middle of the space remaining) as needed.
All dimension texts are placed right in the middle of the measured segment. Nothing is adjusted sideways.
Allow below dimension line: As part of the adjustment, texts may be displayed below the dimension line as well as above.
Allow overlap with Markers: Texts may overlap with the dimension markers. (If this is off, then texts will be adjusted vertically to avoid overlap with Markers.)
