The 3D View panel includes functionality to explore the Stringer Surface in a fully rendered, accurate 3D model.
Model Viewer provides you with the opportunity to review your model in 3D in real-time as you update your surface using Stringer Topo. This is a data accurate representation of your survey surface, able to be rendered with a material, have an aerial photo draped, display contours and the triangulation and vertically exaggerate.
As well, you can use polylines (on layers you select) to be represented by thick lines draped on the surface to represent property boundaries or other features such as pavement markings.
Some functionality in Model Viewer is specifically for Civil Site Design users, however this is a very useful tool for surveyors to establish a representative surface and to present to end customers.
The Surface From Satellite command allows users to generate a Surface by referencing online elevation data. This command can be accessed directly from the Roads tab on the ribbon or via the Toggle Display dialog in Model Viewer.
The elevation data used to build this surface is attained using the Google Elevations API. Building a surface from this data is great for conceptual design or for the purpose of extending an existing Surface. Currently, we have capped the point limit for a single surface at 10,000. However, you can set this limit to be unlimited if you attain a Google Elevations API Key and specify this in the Viewer Settings.
Upon selecting the command the following form is displayed:
Before selecting a surface area to build, users will be required to specify a Projection File, which stores coordinate system data. On selecting the button with the 3 dots, the software will open the Model Viewer Projections Folder. If your coordinate system is not listed, then select the link to access the Spatial Reference website to search and download the .prj file for your required coordinate system.
Specify the colour of the Surface. This colour will be used when Model Viewer is display with a Shaded Visual Style.
Sets whether the elevations downloaded are in metres or feet. Note: This setting does not affect the XY coordinates of the points.
Allows the user to shift the elevations of the downloaded data
The downloaded elevations are not shifted
This option allows the user to shift the elevations by referencing an existing Surface. The user is required to specify a surface and a coordinate (by selecting the picker button). The elevation taken from the existing surface is used to shift the elevations of the downloaded data. By using a Reference Surface, the software will also know where you are in the world and therefore when the satellite imagery will default to this location.
This option allows the user to specify either a negative or positive value to shift the downloaded elevations on to the correct datum.
If Reference Surface is specified, then the user will be required to select this surface from the list.
If Elevation is specified, then the user is required to specify the negative or positive value for the elevation shift.
Allows the user to specify a style for the label
Specify the label style that is assigned to the label. Users can customise the style via the Label Styles command.
Set the height of the label leader. This height is measured from the level calculated from the surface elevation.
Allows the user to specify the surface that is used to interpolate the elevation the label uses.
Select a surface from the drop-down list
Confirm Satellite Data
The Surface from Satellite window is displayed allowing users to define the area to generate the Surface.
Exit the command without building a new Surface.
Upon selecting the Confirm Satellite Data button, the following window is displayed. This window allows the user to specify the area to generate the Surface.
The first step is to search for the area. In the search field (defaulting to the text 'Melbourne'), type in the address and select the ENTER key. If found, the software will pan to the location. By holding down the right-mouse button, users can pan around the view.
Once zoomed to the location of choice, use the Define Area button to specify the area. Upon selecting the button, the user is first required to select the top-right corner of the area. On doing so, the software will shift the view to this location. Next, the user is required to select the bottom-right corner. Upon doing so, a red area is highlighted indicating the area to be downloaded.
This option allows the user to clear the currently defined area allowing the user to define a new area.
This value is the intensity of the points downloaded. As this value is edited, the Point Count value will changed so the user is aware of how any points will be downloaded. By default, the download limit for a given surface is 10,000. However. users can make this value unlimited by using their own Google Elevations API Key, which is the defined in the Viewer Settings.
Thw software will download the elevations for the area specified.
Exit the command without building a new Surface.
Once the elevations have been downloaded, the Surface form will display. The user then specifies whether to create a new Surface or update an existing Surface. If creating a new surface, the user will be required to specify the name of the new surface and the surface style.
