Editing layers in profiles

In Gemini Terrain, you can edit physical layers and advanced section layers in the same way you edit lines in application layers. Editing can be performed both through the properties dialog and by using grips.

Editing layers via the properties dialog

Double-click on the layer to open the properties dialog.

Properties dialog for editing layers in profiles

Editing layers with right mouse click

When you point in the cross-section, you get access to these functions via the right mouse button (context menu):

• Exit and save
• Insert point
• Follow the layer
• Sort clockwise around a given point
• Sort counter-clockwise around a given point
• Close contour
• Insert point with undefined height
• Set height undefined
• Move point
• Add line length
• Helper geometry
• Move dialog to pointer position

Tip

The keyboard shortcuts are displayed to the right in the menu. It can be useful to learn these to work more efficiently and avoid many right-clicks. The concepts for helper options for dynamic line, snapping, and guide lines (intersection calculations) are also useful when editing data in the profile.

Creating new physical layers

You can also create new physical layers when you are in longitudinal and cross-section editing. The Add/Create... option is found in the horizontal list field for layer names.

The relationship between manually edited profiles and source data

Warning

When you make manual edits in the profile, you must be aware that these are independent of the model they were generated from. There is no connection between the base data in the application layer and the generated profiles in the SFI model. If you generate profiles again, any manual edits will be overwritten.

To avoid unintentional overwriting of profile edits, you have the option to lock profiles for manual SFI models. Locked profiles will not be affected by the profile generator. The same applies to the building of theoretical layers.

The Lock on option is found on the right mouse button in the list of profiles.

Locking a profile with right-click

Note

This functionality is only active for SFI models with manual calculation method. In road projects with automatic calculation method, the profile generator automatically rebuilds the layers.

Group editing

In many cases, you want to perform an operation on multiple profiles and layers at the same time. Functions for this can be found under Group editing...

Editing theoretical layers

So far, we have only discussed physical layers. When the contractor documents roads, ditches, and tunnels, they also build theoretical layers in the profile. You can edit theoretical layers in the profile in the same way. Typical contractor tasks are described in more detail in a separate section.
