Dynamic markers indicate start and end points along reference shapes.
For example, markers might indicate the portion of a road along which a series of lamp columns will be placed, or the portion of a road to which a swept object might be applied.
In viewports, marker objects appear as wireframe cubes. A green cube indicates the start point, and a red cube indicates the end point (you can change these default colors on the Civil View Preferences panel). To change marker values, you can drag the cubes along the reference shape.
The Start Marker value is constrained to prevent it from having a greater value than the end marker. The End Marker the value is always at least one unit greater than the current Start Marker value.
In a dialog, you can enter a marker value directly, or drag the spinner control arrows up or down.
Spinner Control Tips
- Holding down the Ctrl key while dragging the spinner moves the marker at a faster rate.
- Right-clicking the arrows of any spinner control resets the control to its default value (typically zero).
- A good trick for quickly placing markers over a short section of the reference shape is to position the start marker first, then right-click the arrows of the end marker spinner to bring the end marker just in front of the start marker. Then you need only to move the end marker a short distance to place it in the required position.
- While any spinner control is active, you can display a calculator called the Numerical Expression Evaluator by pressing Ctrl+N. 3ds Max evaluates the expression you enter, and displays the result in the Result field. Clicking Paste then replaces the spinner value with the result of the calculation. Clicking Cancel exits the Expression Evaluator.
