It’s easy to start exploring Teigha Civil using a simple console application named TCTest. Using it, you can see how Teigha Civil opens, saves, and renders files, and more.

#### Running TCTest

TCTest is located in the Civil\\Tests\\TCTest folder.  
To run it:  
TCTest script - BATCH "command\[,...\]" INPUT\_FILE &lt;inputFile&gt; OUTPUT\_FILE &lt;outputFile&gt;  
For example:  
TCTest script - BATCH "load,render" INPUT\_FILE 1.dwg OUTPUT\_FILE 1.bmp  
The result is displayed in the console.

#### Most useful TCTest commands

- load — Loads a file.
- MTLoad — Loads a file in multithreaded mode (same as «MT Open» in OdaMfcApp).
- partialLoad — Loads a file in partial loading mode (same as «Partial Open» in OdaMfcApp).
- saveCurrentVer — Saves a file to the latest version supported by Teigha Civil. Useful for testing successful saves (no corruption) or updating your dataset to the latest file version.
- render – Renders a drawing and creates a bitmap file as OUTPUT\_FILE. Useful for testing rendering without OdaMFCApp or Teigha Viewer. The resulting bitmaps can be compared with an external tool.
- enableZoomExtens /disableZoomExtens — Sets zoomExtents mode for rendering.
- explodeToPrimitives / explodeTree — Tests correctness of explode
- transformObjects — Tests correctness of the transformation of civil entities.
- dump — Prints to the console information about a file and its structure (header, layers, linetypes, regApps, etc.).

To see the list of all TCTest commands, run TCTest without parameters.
