Opening and Saving Files
Within DoubleCAD you can choose to open a saved file or start a new file. You can also open new and saved files from within DoubleCAD, and there are several options for saving files.
Note: The General page of the Program Setup contains several settings for opening and saving files.
Opening Files
Default UI Menu: File/Open
Ribbon UI Menu:
Hotkey: Ctrl+O
Files of type: By default, you will open a .2CD file. Use this list if you want to open a file of a different format. Open as read-only: A read-only file can be viewed only; it cannot be edited. Description: Displays text entered in the Subject field of the Drawing Properties window. S Show Preview: Displays a thumbnail of the drawing. Only DoubleCAD files (.2CD and .2CT) can display previews. Setup:* When importing files of other formats, provides access to conversion options.
Note: You can select multiple files from the file window to open at the same time. Simply hold down the Shift key to select multiple files.
Saving Files
Default UI Menu: File/Save
Ribbon UI Menu:
Hotkey: Ctrl+S
Saves the current drawing to disk. If the file was not previously saved, the Save As window will appear.
Save as type: By default, you will save the file as a .2CD file. Use this list if you want to save (export) the file to a different format. Setup: Enables you to set parameters for the saved .2CD file . When exporting to another file format, provides access to conversion options.
Save:
Drawing: Saves the entire drawing. Selection: Saves the selected objects only. If Prompt for Summary Info is checked in the General page of the Program Setup, the Summary Info window will appear before saving.
Tile Area
DoubleCAD splits a large image into pieces (horizontal stripes) in order to save memory while rendering, and then stitches these fragments into a single image.
The filter settings dialog bitmap (bmp, jpg, gif, png) now contains an option called Tile Area, which allows users (based on the amount of memory) to establish the image fragmentation settings
Minimal (default) value – 1 megapixel, corresponds to the image size of 1000 x 1000.
Maximal value – 256 megapixels, corresponds to the image size of 16000 x 16000 (maximum resolution).
If you set"Tile Area" = 256, then for any size of image, fragmentation will not work.
Please note: When installing large values "Tile Area" is very likely to be used throughout the computer's memory which can lead to system instability.
Undo/Redo File Buffer
With this Save file option, the Undo/Redo buffer of a file is saved when the file is closed or when the application closes. The buffer is re-loaded when the file is reopened and can be used from the last point. Some operations are not saved within the Undo/Redo buffer.
Summary Info
Records general information to be saved with the drawing.
If Prompt for Summary Info is checked in the General page of the Program Setup, the Summary Info window will appear when you save the drawing. File Name and Directory: Information for files that have already been saved. Keywords: Text used when searching for this file. Subject: Descriptive text that appears in the Open and Save windows. This text can also potentially be used by Windows file search utilities.
Tip: If a drawing is being saved as a symbol, the Title should be a short description of the symbol, and Subject contains a more detailed description.
Save Preview Graphics with Drawing: Sets the type of graphic image that will be stored with the drawing, so that it can be previewed in DoubleCAD and in other Windows programs. None: No preview graphics will be saved. Bitmap: Suitable for large files because the bitmap will use the same amount of space no matter how complex the drawing is. Metafile: Suitable for small files because it displays more detail. Symbol previews are generally stored using this option. Create Preview by: Saves the preview as the plan view or by the current view and render mode.
Time Stamp
The time stamp feature adds system information about the date/time of drawing creation, the date/time of the last modification, total time spent editing the drawing and the total time of the last editing session.
The information is available in "Summary Info" dialog (File | Drawing Properties...).
IFC Export and BIM
IFC stands for Industry Foundation Classes (IFC). This is a standard data model used to describe data for the building and construction industries It is a platform-neutral, open file format specification commonly used collaboration format for Building information modeling (BIM). The following Items are exported to IFC:
- Architectural objects
- Custom Properties
- Property Sets
The data is mapped as follows:
