Drape Line

(This functionality is available with the Modelling module)

This command is used to modify lines or create new lines such that they are draped on the current model.

This allows any lines to be modified or copied such that the modified or copied lines becomes coincident with the model surface.

For example, a title boundary without any elevations could be draped on the model, edited to become a break line (and perhaps a new model boundary), and then new model(s) formed as desired.

Drape Line dialog box

Item	Used to
Model Name:	Display the name of the currently displayed model. Any previously created model may be displayed using the Display Features command.
Block is active:	Indicate whether there is a block currently active. This message is only displayed if a block is currently active. Refer to the Block command for information on creating and using blocks.
Line ID:	Key in the identifier of the required line, or display the identifier of the line selected with the mouse. If a block is active the Line Identifier field is disabled and cannot accessed, as the selected lines are defined by the block definition.
Option
Modify	Modify the selected lines such that they are draped on the model.
Duplicate	Create a copy of the selected lines and modify the copies such that they are draped on the model. This option leaves the original selected lines unchanged.
OK	Perform the drape according to the option selected.
Cancel	Close the dialog box.
Notes	The draped lines include newly created points at all model triangle crosses coincident with the model elevations. Pre-existing points in the draped lines have their elevations added or changed to be coincident with the model elevations. Draping does not alter the triangulation in the model. To incorporate the new points and any draped break lines in the model, you will need reform the model. This will obviously alter the triangulation.
