(This functionality is available with the Profiles and Design module)
Control the scale and the dimensions of the cross section to be output to a CAD system.
Setting configurations in this dialog will be saved in the currently open cross section CAD output layout file.
The Datum and Scale option can be chosen from the CAD Output dialog. This dialog is displayed after selecting the CAD Output command from the Profiles task in a cross section view.
Datum and Scale dialog box
| Item | Used to |
| Scale: | This group is used to set the scale that is used when plotting the drawing from the CAD system.
For LISCAD CAD, the CAD file is created at the scale entered in plan units (millimetres on the
plan). For AutoCAD and MicroStation the CAD file is created at full size according to the co-ordinates in the data base. In these two cases the scale entered here is used only to calculate the text and symbol sizes in ground units, such that when plotted at the entered scale, they will be at the required size on the plan. |
| Horizontal 1: | Key in the horizontal scale that is used to determine the plotting extents of the cross section. |
| Vertical 1: | Key in the vertical scale that is used to determine the plotting extents of the cross section. |
| Scale Label Settings: | Open the Scale Label Settings dialog. This is used to define the attribute information for the horizontal and vertical scale text. |
| Start Distance/Chainage: | Key in the start distance or chainage of the primary long section in the display |
| End Distance/Chainage: | Key in the end distance or chainage of the primary long section in the display. Note: The "Start...." and "End...." fields will either show "Chainage" or "Distance" depending on the settings defined in the Configure Alignment dialog. If alignments are configured for chainages and the primary long section in the window is based upon an alignment then additional drop down list fields will become available so that any chainage ambiguities can be resolved. |
| Datum | |
| Datum Shift Below Minimum Elevation: | Key in a value that is used to determine the relationship between a cross section and the
datum elevation that is displayed. For example, if the value entered is 0.5 and the lowest elevation in the cross section is 19.432 then 0.5 would be subtracted from 19.432 and then the resultant 18.932 would be rounded to the closest 0.5 resulting in a datum elevation of 19.000. |
| Fixed At: | Key in a value that is used to set a fixed datum elevation for all cross sections. |
| Recompute Fixed Datum: | Press this button to recompute the lowest elevation in the cross section set. |
| Height Shift Above Maximum Elevation: | Key in a value that is used to determine the relationship between a cross section and the
maximum elevation of the grid area. For example, if the value entered is 0.5 and the highest elevation in the cross section is 19.432 then 0.5 would be added from 19.432 and then the resultant 19.932 would be rounded to the closest 0.5 resulting in a maximum elevation of 20.000. |
| Datum Label: | Toggle the output of the base elevation datum value. |
| Datum Label Settings: | Open the Datum Label Settings dialog. This is used to define the attribute information for the datum elevation value text. |
| Section name Settings: | Open the Section name Settings dialog. This is used to define the attribute information for the Section name text. |
| CAD System Options: | Display the CAD System Options dialog. |
| Layout Determines the layout of the cross sections that are output. For each chainage range the cross sections will be output in columns of increasing chainage from left to right. |
|
| Top Down: | Output the cross sections with the chainages increasing from the top downwards. |
| Bottom Up: | Output the cross sections with the chainages increasing from the bottom upwards. |
| Maximum Plan Height: | Key in the maximum plan height. This option defines the drawing height of the page in the CAD file. So cross sections will be stacked to that height, then move on to the next row. |
| Minimum Vertical Separation: | Key in the minimum vertical separation between the columns of cross sections. This minimum value allows the datum lines for all cross sections to line up along each row. |
| Minimum Horizontal Separation: | Key in the minimum horizontal separation between the rows of cross sections. This minimum value allows the centre lines for all cross sections to line up down each column. |
| Label all Tables: | Output labels for each table row in every cross section. |
| Label Left Hand Tables Only: | Output labels for the table rows in the first column of cross sections. |
| Offset Limits | |
| Right Limit: | Select and key in a restriction width for cross sections that are output to a CAD system. If the check box is selected a square cut will be applied to the left hand side of each cross section at the designated offset limit. |
| Left Limit: | Select and key in a restriction width for cross sections that are output to a CAD system. If the check box is selected a square cut will be applied to the right hand side of each cross section at the designated offset limit. |
| OK: | Close the dialog and save the current settings. |
| Cancel: | Close the dialog without applying the changes. |
