Slope

The laSlope command draws an annotation leader with arrowhead and attached text, displaying the slope of a selected path. The slope is calculated based on the path length and the difference in height between the the start and the end point of the slope path.

Insert a slope

Steps:

1. Pick an existing curve in the model to define the Slope annotation, or select a different option in the command line.
   • Polyline: the slope will be created as if you were drawing a polyline.
   • Spline: the slope will be created as if you were drawing a spline.
   • Arc: the slope will be created as if you were drawing an arc. The first click determines the insert point. Second click determines a middle point in the arc. Third and last click determines where the arc ends.
2. Press ENTER, ESC or right click to end the command.

Control points

The slope object has as many control points as the curve it was created from.

In addition, it has a Move control arrow, to move the whole object.

Slope control points are automatically enabled when selecting them one by one. To turn one ore more slope object control points on just select them and run the PointsOn command (or press F10). To turn the points off, press ESC button or run the PointsOff command.
