Drape Element tool settings

Setting	Description
Direction	Specifies the view or axis to drape along.
Output Level	Select the Level where the draped element will be placed. Select "From Element" to place the draped element on the same level as the input element.
Height	Height in master units of the box used to select points to be considered while draping the element. Tip: Dynamically measure on the reality model by clicking on the Measure icon.
Keep Original	Keeps the original draping element.
Use All Reality Models	Use all attached reality models during processing.
Max Chord Height	Maximum Chord height (in master units)is used only with curve elements to convert them to linestring before running the drape process. It corresponds to the tool Facet Curve (Tools/Curves/Curve Utilities/Facet Curve). This parameter is used to define the max chord height to stroke the arcs before draping the line on the reality model surface. Tip: Dynamically measure on the reality model by clicking on the Measure icon.
Generalization	Applies a generalization algorithm to reduce the number of points on the produced draped element. Douglas Peucker – a well known algorithm to reduce the points on a curve while keeping within a tolerance. Stream Parameter: Uses the four MicroStation stream parameters to perform generalization. See the MicroStation reference guide for details. `KEY-IN:` `POINTCLOUDADV GENERALIZELINE`
Tolerance	A value in master units that will be applied to the generalization process. Tip: Dynamically measure on the reality model by clicking on the Measure icon.
