Add a transition to fill an area between two existing grading objects or to create a grading that has transitioning values.
A transition is an area that merges the grading of the regions on either side, for example, from 3:1 to 2:1.
There are several ways to create transitions:
- You can select a location within an existing grading.
- You can select a location between two existing gradings. The transition start and end points are defined by the existing projection lines.
- You can select start and end points for the transition and then define the parameters to use at each end. You can use the same criteria for both ends or you can switch criteria.
In addition, you are sometimes prompted to create transitions when you use the Create Grading command. This occurs when the start point of a new grading is inside or touching an existing grading.
To insert a transition between existing gradings
- Click Home tab
Create Design panelGrading drop-downGrading Creation Tools
.At the Command prompt, enter GradingTools. - Click the arrow next to . Click
Create Transition. - Select the feature line.
- Click the location where you want to add the transition (between two existing regions).
To insert a transition within an existing grading
- Click Home tabCreate Design panelGrading drop-downGrading Creation Tools.At the Command prompt, enter GradingTools.
- Click the arrow next to . Click Create Transition.
- Select the feature line.
- Enter Points.
- Select the grading side.
- Select the location where you want to add the transition (within an existing grading). The station of the point you selected is displayed at the command line. You can change it or press Enter to accept the location.
To insert a transition by defining different criteria and values
- Click Home tabCreate Design panelGrading drop-downGrading Creation Tools.At the Command prompt, enter GradingTools.
- Click the arrow next to . Click Create Transition.
- Select the feature line.
- Enter Points.
- Select the grading side.
- Select the location where you want to add the transition. The station of the point you selected is displayed at the command line. You can change it or press Enter to accept the location.
- Follow the prompts to define the criteria values for the start of the transition.
After you define the values, the following prompt is displayed:
Select the end point or [Criteria/Next/Previous/Both/Length]:
- Do one of the following:
- Select the end point by clicking a location in the drawing. Then follow the prompts to define the criteria values for the end point.
- Enter Length to specify a length for the transition. Then follow the prompts to define the criteria values for the end point.
- Enter Criteria and select a different criteria to apply to the end point of the transition. If you select a criteria that is different from the criteria applied to the start point, the two are blended to create the transition.
- Enter Next to define the transition end point as the edge of the next grading on the footprint (up station).
- Enter Previous to define the transition end as the edge of the previous grading on the footprint (down station).
- Enter Both to straddle the grading transition between the next and previous grading edges on the footprint. This option overrides the selected start point.
