Check this box to display previously magnified detail in the 3D Window whenever the 3D Window is rebuilt. Click this pop-up to select the precision of the chosen Angle Measurement Unit. Click this pop-up to select from various standard Angle Measurement Units. Click this button to move the ArchiCAD Temporary Folder (holds Autosave files and other temporary documents) to another volume with at least 8 MB of free disk space (preferably more). Note: remote network volumes may cause very slow performance. Check this box to automatically Redraw the Floor Plan after deleting any element(s). Click this button to use the standard CAD "click-click" drafting method (default). Example: to draft a Line, click the mouse button at the first endpoint and release it, move to the other endpoint and click to complete the Line. Click this button to use the standard Macintosh "click-drag" drafting method. Example: to draft a Line, click the Mouse button down at the first endpoint, drag while holding it down and release at the other endpoint. Enter a value here for the distance at which the SmartCursor "snaps" to an element. Enter the number of Undo-able or Redo-able editing operations between Autosaves here. Enter a time interval between Autosaves here. Example: 120 secs = 2 min., etc. Click this button so Autosave will be triggered after a specified number of Undo-able or Redo-able editing operations. Click this button so Autosave will be triggered at specified time intervals. Click this button to turn off Autosave. Note: it's a good habit to use File/Save ([cmd]-[s]) to save your work frequently. Click this button to have ArchiCAD save your work in the background periodically. Note: creates a backup file in the ArchiCAD Temporary Folder which can restore work otherwise lost by serious interruptions (power failures, system errors, etc.). Use the slider to define one of four levels of detail for the 3D Report. Click this button to create a 3D Report window summarizing information about the Imaging procedure for viewing after the Imaging process is completed. Click this button to allow interruption of any Imaging process with Alert dialogs warning you of problems. Check this box to display a 3D Progress information window with a thermometer indicator showing image completion stages when Imaging. Check this box to bring the 3D Window to the front whenever the 3D Projection Settings or Rendering modes are changed. Check this box to Rebuild the 3D Window whenever it's brought to the front by mouse-click or menu command after a 3D element is changed or added to the Floor Plan. Use this list to select Line types for Slab & Roof outline display on stories below the one on which they were created. Use this list to select Line types for Slab & Roof outline display on stories above the one on which they were created. Enter a Custom Angle value here for Mouse/SmartCursor constraint. Note: when you define a Reference Edge or Reference Vector with the Parallel or Perpendicular Drafting Modifiers, this value will be updated with the new Custom Angle. Check this box to enable Mouse/SmartCursor constraint at the defined Custom Angle from any Edit Origin by holding down the [shift] key. Enter a Fixed Angle value here for Mouse/SmartCursor constraint. Check this box to enable Mouse/SmartCursor constraint at the defined Fixed Angle from any Edit Origin by holding down the [shift] key. Check this box to constrain Mouse/SmartCursor movement to 0°, 90°, 180° and 270° from any Edit Origin by holding down the [shift] key. Check this box to display Inches even when equal to zero (1/2" is shown as 0' 1/2"). Check this box to use the European method for rounding decimal values (a superscript "5" is added to indicate fractions between .25 and .75). Check this box to hide zeros to the left of the decimal point. Note: 0.12 (meters) is shown as "12" (cm). Click this pop-up to define the number of decimals displayed for the selected Measurement Unit. Click this pop-up to select from various Measurement Unit options. Click this button to remove the selected Dimension Preference from the pop-up menu above. Click this button to add the Custom Dimension Preference defined below to the list of available choices. Click this pop-up to select from various predefined Dimensioning Standards. Standards include: • ANSI • DIN • Any Custom user definition Click this pop-up to set the number of decimals displayed for Text Height & Rotation Angle values in dialog text boxes. Click this pop-up to select the accuracy of the chosen Measurement Unit. Click this pop-up to select from various standard Measurement Units. Click this pop-up to select another Preferences dialog. Click Cancel to close this dialog without confirming changes to any of the different Preference dialogs. Click OK to confirm any new Preferences and leave this dialog.
