Start with Layout Ribbon Panel.
To draw an alignment with floating elements, construction elements (tangent or circle) need to be drawn in the drawing first. Click on the Fixed Element icon.
Draw Arc +/ Arc – / Line element. When finished, click on the icon Draw with floating elements.
The command interface differs based on a combination of construction elements that have been selected. There are several combinations possible, from single construction element (tangent or circle), tangent – circle combinations to circle – circle combinations which include circle orientation in the same or opposite direction.
Select the first and second fixed element and press Enter.
The following dialog box of combinations to draw floating elements opens up (which dialog box of combinations open depends on the selected combination of construction elements). In this tutorial are presented three possible combinations.
1. tangent – circle combination
After the selection of the tangent and circle construction elements the following dialog box opens up:
Select the proper combination. Then the detailed user interface opens, where the radius value can be defined. Press OK to draw the alignment.
2. circle – circle combinations
After the selection of two circles of construction elements in the following dialog box select the proper combination and in the detailed user interface define specific parameters, like the length of spiral or radius value.
3. Tangent-tangent combinations
Based on two construction tangent elements, three different combinations of floating horizontal elements creation are possible. Select the proper combination and in the detailed user interface define the length of spiral or radius value.
In the Draw lanes and widenings dialog box choose the appropriate vehicle combination.
