Input Cross-Section

To create a new cross-section geometry, choose New from the Cross Section Selection box in the View toolbar. After entering the cross-section's name, TuMan displays an empty drawing area in the Cross Section View.

You may first input the outline of the tunnel tube cross-section. Make sure the Tunnel Wall item is selected in the Group Selection list box, which means, that the next objects you draw will belong to the Tunnel Wall group. Then use the Line tool, Arc tool or Circle tool to input the outline of the cross-section. The Catch modes may help you, to find the position of grid points, line endpoints or intersections more precisely.

You can break, shorten or lengthen previously drawn lines with the Break tool, Trim tool or Stretch tool. Right-clicking on an object provides access to the Properties command in the context menu. Select this item to open the Object Properties dialog, where you can modify most of the object's parameters (for example, material properties). Enable the Show Relative Position option in the View Settings dialog, if you want TuMan to display the relative position to your previous mouse click while dragging an object.

Select Prediction Plane from the Group Selection list box, if you want to define prediction planes in the tunnel. These planes will be exported to the WinProp database and are needed for calculating wave propagation and radio network planning on arbitrary prediction planes.

Further segment groups are available for modeling more details within a cross-section.

The Cross Section List can be used to save or load cross-section geometries independent of the tunnel document. There you will find other commands for managing several cross-section geometries as well.
