Within TurboCAD LTE you can choose to open a saved file or start a new file. You can also open new and saved files from within TurboCAD LTE, and there are several options for saving files.

Note: The General page of the Program Setup contains several settings for opening and saving files.

See General Setup

Opening Files

Default UI Menu:

Ribbon UI Menu:

Hotkey: Ctrl+O

Files of type: By default, you will open a .tcw file. Use this list if you want to open a file of a different format.See Other CAD Formats. Open as read-only:A read-only file can be viewed only; it cannot be edited.Description:Displays text entered in theSubjectfield of theSummary Infowindow. See Summary Info).Show Preview:Displays a thumbnail of the drawing. Only TurboCAD LTE files (.tcw and .tct) 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.

Purge

Default UI Menu:

Ribbon UI Menu:

The purge tool is designed to make your files smaller by eliminating un-used elements that are stored in your file. For example, you can purge un-used blocks, line styles, or object styles.

1. Select File | Drawing Utilities | Purge. The Purge dialog will open.

1. Select the items you wish to purge. If necessary expand the tree so you can select sub-items. Alternately you can press the Purge All button.
2. After selecting your items to press the Purge button.
3. Press Close when you are finished.

Purge Options

Show Used Items- When this option is selected the tree will show the items in the tree. You cannot purge while this option is on. Selecting items in the tree will show purge parameters for that item type. The parameters are displayed in a text box directly below this option checkbox. Purge default linestyles: If this option is turned on un-used default linestyles will be purged from the drawing. This option is off by defaullt. It is recommended to use this option with caution.

Purge default brushstyles: If this option is turned on un-used default brushtyles will be purged from the drawing. This option is off by default, it is recommended to use this option with caution.

Clear all undo records before action: If this option is turned on all undo buffers will be deleted. This prevents issues with an attempt to undo purged items. This option is on by default.

Confirm each item to be purged: If this option is on you will be presented will a confirmation dialog for each item that is being purged from the drawing. This option is on by default.

Saving Files

Default UI Menu:

Ribbon UI Menu:

Hotkey: Ctrl+ 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 *.tcw file. Use this list if you want to save (export) the file to a different format. When exporting to another file format, provides access to conversion options. See Other CAD Formats.

Save:

Drawing: Saves the entire drawing. Selection: Saves the selected objects only. IfPrompt for Summary Info is checked in the General page of the Program Setup, the Summary Info window will appear before saving.

Tile Area

TurboCAD LTE 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. . See Loading an Individual ,Symbol into the Library.

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 TurboCAD 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 | Summary Info…). The information is stored in the following file formats: TCW, DWG, DXF.

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:

1. Architectural objects Architecture Tools
2. Custom Properties
3. Property SetsProperty Set Definitions

The data is mapped as follows:
