How can I insert 3D objects?
To insert 3D objects in TcpMDT, such as vegetation, traffic signs, or street furniture, you have specific tools that allow you to place them individually or distribute them along an axis.
Here are the steps and methods available to do this:
Standard Insertion Procedure
To begin, you must access the command Maps > Insertion of 3D Objects (or through the ribbon in Maps-Realism > Insert 3D Object). Once executed:
Object selection: A window will open where you can choose the desired object classified by categories such as Vegetation, Signs, and Miscellaneous.
Position definition: You have several options to place the object in the drawing:
Specify on screen: You manually designate with the mouse the points where you wish to place the object; TcpMDT will automatically insert it at the ground elevation given by the current surface at that point.
Along an axis: If you select an axis file (.eje), you can specify an interval (defining Initial Station, final station, interval, and lateral offset) or specify specific stations with their respective offsets.
Final configuration: You can set the insertion angle (absolute or relative to the axis) and the scale of the block before validating the operation.
Importing Custom 3D Objects
If you wish to use your own models in OBJ or FBX formats, TcpMDT includes a 3D Object Importer accessible from the Code Database. For them to work correctly, you must adjust the following parameters in the importer:
Orientation: The Z vector must be vertical, as many 3D applications use the Y axis for height.
Pivot point: You must position the model so that the importer's 0,0,0 point coincides with the desired insertion point in the drawing (for example, the base of a lamppost).
Scale: It is recommended to normalize the scale so that the maximum dimension of the object is 1, which makes it easier to assign the appropriate size when inserting it into the CAD.
Export: Once adjusted, it is exported to the MDT user library so that it is available in the insertion commands.
Visualization and Utility
These objects are fundamental for improving realism in Route by Terrain and TOUR BY ROAD simulations. Furthermore, when exporting to BIM format (IFC), TcpMDT can automatically include these elements, such as inserted vertical signage, maintaining their properties and geographic position.
For objects that must closely follow the geometry of the roadway, such as guide posts or barriers, the specific Insert Linear Objects button within the TOUR BY ROAD command is used.
