Copy Geometry from Command List to Application Layer

Use this dialog to copy geometry from objects in the command list to an application layer.

Where can I find the dialog?

In the toolbox of the terrain model drawing, select Copy Geometry from Command List to Application Layer...

Using the Dialog

You can copy geometry from Gemini models and other inserted objects in the command list, such as IFC files.

You can choose to copy with or without elevation. If you want to copy lines with radii, for example, roads and intersections for use in zoning plans, you must copy without elevation. If you copy with elevation, radii will be split into line segments. A value of 5 mm is used for arrow height (deviation between radius and straight line) horizontally, and 1 mm for arrow height vertically.

Geometry Type

Gemini Models

You can copy geometry directly from Gemini models. The data you can extract varies depending on the data type:

  • Road bodies and intersections: Lines
  • Line definitions: Generated points (if the option is selected) and lines
  • Line definition data: Points and lines
  • Excavation pits: Points, lines/polygons, and triangle nets

Line definition has its own option. You can generate profile and curve points in the same operation. This gives you single points in the centerline with elevations from vertical curvature. You choose the profile interval to use, for example, 10 meters. Note that curve points are also included. Profile number becomes the point number (S_OBJID).

Gemini Models and Other Objects in the Command List

You also have an option to copy geometry as it is drawn on the screen (WYSIWYG - What You See Is What You Get).

What you can copy depends on whether you are in 2D or 3D view. In 3D view, for example, you can copy triangle models for roads, intersections, and excavation pits. Note that the entire model must be active. This will not work if you have defined a terrain model area that intersects the model and clipping is enabled.

Options

Surfaces in IFC files can be represented by geometry types such as polygon-based surface sets and triangle nets. Polygon-based surface sets can be converted to triangle nets during the copying process.

A surface can also be represented by different geometry types as multi-geometries, for example, a triangle net for each triangle in the surface. These multi-geometries can also be merged into a single triangle net during the copying process.

Result Application Layer

You decide where the result will be placed with the result application layer option. By default, the program suggests the active layer. Only application layers open for editing are listed in the dropdown menu. If you select blank in the list, the result will be placed on the clipboard.

Properties

You can also choose to include properties in the copying process. After you click OK in the dialog, a new dialog appears where you select which properties to copy. The options are:

  • All attributes
  • Only attributes that exist in the application layer
  • No attributes

This is especially useful for inserted IFC models, which often have many property sets. The property set at the top level is copied. Note that the GUID is also copied, and you can find it under the property S_PARENTGUID.

If it is important to reduce the amount of information to the desired level, since IFC models often have a lot of information that is irrelevant to the user, you can solve it as follows:

  1. Copy with All attributes.
  2. Open the metadata tab and delete attributes you do not want.
  3. Select Only attributes that exist in the application layer the next time you copy data from IFC.
