A button has been added to the project's topographic surface table, available in the application's toolbar, for exporting the selected surface to a points file. The export format is a comma-delimited value file with the X, Y, Z coordinates of each point on each line.
As of version 2022.g, the points forming the topographic surfaces of the project can be modified. For this purpose, the following options have been added to the application's toolbar.
The "Add points", "Delete points" and "Move points" tools can only be used on "Mesh" type topographic surfaces. "Grid" type topographic surfaces, usually imported from Web Coverage Services (WCS), can be transformed into meshes using the tool for simplifying surfaces (see new feature "Simplifying a topographic surface").
As of version 2022.f, Open BIM Site allows a topographic surface to be entered by placing topographic points on the work area. To do this, the "Define using points" button has been added within the "Topographic surface" group available in the application's toolbar.
Once the points have been entered, the application will automatically generate the surface and it will be added to the list of the project's topographic surfaces.
The new snap, "Fictitious intersection", has been included, which improves object snap tracking as it is able to detect possible intersections between objects that are at different heights.
This tracking makes the design more manageable and results in a more organised object distribution.
Currently, Open BIM applications with a 3D work environment have a tool window where the introduction mode of the model components can be configured. As of version 2022.c, when selecting "3D mode" it will no longer be necessary to specify the workplane nor the displacement value. Therefore, these parameters are left for the "2D mode", thus eliminating the duplicity that was present with both methods when entering or editing the position of elements that do not refer to other objects.
The interface for selecting the reference system of the job available during the linking process with the BIMserver.center platform project has been modified. Now, via the "Reference system selection" button located at the top of the window, the base reference system to be used is chosen. This displays a tree with the reference systems available in the BIM project from the contributions that were previously marked for import.
In the field of topography, contour lines are lines that connect points on a map with identical altitudes. Thanks to this technique, areas with different elevation differences can be easily identified.
The generation of contour lines in Open BIM Site is automatic. However, users can control their visualisation of the 3D model of the site using the application's left-hand sidebar.
The "General parameters" panel, available in the application toolbar, has been divided into two tabs. The "Site data" tab contains the information related to the georeferencing of the model that was already present in previous versions of the tool. To configure the viewing of contour lines, the "View options" tab has been added with the following parameters:
As of version 2022.c, Open BIM Site allows points files to be imported for describing a topographic surface. To do this, the "Points file" option has been added as a possible data source in the definition panel of a topographic surface.
In order for a point file to be interpreted correctly by the application, it must meet the following requirements:
The "Map" and "Topographic surface" options have been added to the "Site components" group in the application’s toolbar. Thanks to these new buttons, maps and topographical surfaces from WMS and WCS web services can now be entered directly onto the drawing area. To do this, users must specify with the mouse pointer the two points corresponding to the opposite corners of the rectangle establishing the map section.
It is now possible to indicate on which plots of the site model the project will be carried out. To do this, an option has been included in the plot definition panel with the caption "Affected by the project". When marking this option, the plot outline will be coloured in a different colour from the work area and this information will be exported into the site model for the project that the job is connected to on the BIMserver.center platform.
As of version 2022.c of Open BIM Site, the Web Map Service of the Portuguese organisation "Direção-Geral do Território. Divisão de Informação Geográfica" can be accessed.
The "Ortos 2018 Portugal-Continent" option has been added to the "Maps" menu available in the application’s toolbar. According to the performance of the WMS service, the following coordinate systems can be used to obtain the map section that will be inserted in the work area:
