Sat: The saturation level for the color (amount of color), up to a maximum of 240. Lum: The luminosity (brightness) of the color.


Default UI Menu: Options/Program Setup/Constraints

Ribbon UI Menu:


Settings and controls for geometric and dimensional constraints. img
Auto Add Constraints: If checked, the Auto Add Constraints tool is enabled. Any constrainable geometry you create while this is active will have constraint automatically assigned. Update Connected Objects while Dragging: Dynamically updates the position, shape, and size of constrained objects as you drag them within the Edit tool. Connected Objects Editing: DCM Default: Changes to any part of a set of constrained objects can affect all objects equally. Use Priority Level: Constraint changes to any part of a set of objects will affect that part first, with minimal changes to the remaining objects. Incremental Evaluation: Constraint changes are constantly checked and changes are being made. If disabled, the results will be checked only after changes are made. For large scale changes, this option should be enabled.

Constraint Markers and Dimensions

Place marker to the same layer with object: Constraint markers are placed on the same layer as the object that is constrained. Otherwise, they are placed on their own layer. Show variable name in dimension text: Displays the variable name in parentheses after the dimension value. Printing: Choose whether constraint markers and constrained dimensions will be included when printing.


Default UI Menu: Options/Program Setup/Desktop

Ribbon UI Menu:


Controls what appears on the screen. img

Workspace: Controls the display of the working area Status Bar: Displays or hides the Status Bar. Scroll bars: Displays or hides the scroll bars. Rulers: Displays or hides the rulers.

Tip: You can switch off the paper until you're ready to print, then use the Page Setup (see Page Setup to place your drawing on the page.

OpenGL Hardware Acceleration: Available if your video card is equipped with an accelerator, take this characteristic into account while performing a render. Render new window: When you render your drawing, the render view will open in a new drawing window. Background Render: With this option, DoubleCAD tools work faster in Render mode; rendering will "interfere" less with other tools. This setting can only be applied when working with one window.

File Locations

Default UI Menu: Options/Program Setup/File Locations

Ribbon UI Menu:


Enables you to specify the folders where DoubleCAD places several types of program files. img

Templates (.2ct) - Files in which you save settings as well as block libraries, symbol libraries, and scripts, that you can use to start a new drawing. Backups (.bak) - Backups that are created if you check Make Backup Copies option in the General page. AutoSave Files (.asv) - Files that are saved automatically, if this option is turned on in the General page. These files allow you to restore work after a system crash. Symbol Library Files (.slw) - Sets of related symbols, saved to one common .slw file or a set of drawing files saved to a specified folder. Drawings (.tcw) - Drawings and models you create in DoubleCAD. Publish to HTML Files - Files created using File / Publish to HTML. Print Styles: See Print Style Options Shapes (.shx): Shape files (.shx) used in the creating of line styles. (This is not the same as *.shx font files.) See Line Styles

Tip: If you have two disk drives (or access to a network drive), it is wise to have your backup files automatically saved to a second drive.
