To import coordinates into Rhino, particularly when dealing with files that contain spatial data like FBX models, you typically use Rhino's import function and configure specific settings during the process. Based on common workflows and information from the reference, this involves selecting the file and adjusting import options like scaling and axis mapping.
Importing Files Containing Coordinates
When you have a file format (such as FBX, DWG, DXF, or others) that contains 3D geometry and its associated coordinate information, Rhino's import command allows you to bring this data into your project. The exact steps and options available can vary slightly depending on the file type and your Rhino version, but key considerations often include handling the scale and the orientation of the coordinate system.
Key Import Settings
According to the provided reference regarding importing, specifically mentioning FBX files, two important settings to look for during the import process are:
- Prompt to scale on import: When selected, this option allows Rhino to prompt you to specify a scaling factor or units conversion during the import. This is crucial because different software or sources might export files in different units (e.g., meters, feet, millimeters). Scaling ensures the imported geometry is the correct size in your Rhino model.
- Map FBX Y to Rhino Z: This setting addresses potential differences in coordinate system orientation. Many 3D applications use a Z-up convention (where the Z-axis represents vertical height), while others use Y-up. Rhino traditionally uses Z-up. If the file you are importing uses a Y-up system (like some FBX files), enabling this option tells Rhino to interpret the incoming Y-axis data as the vertical Z-axis in your Rhino project. This correctly aligns the imported model with Rhino's standard orientation.
The reference states, "And you essentially you want to click on these two. So prompt to scale on import. And map fbx y to Rhino Z." After configuring these options, you would typically confirm the settings by clicking "Okay."
Bringing the File Into Rhino
Once you select these import settings and proceed, Rhino processes the file. The reference notes that this action "is going to bring the file into Rhino." The geometry and its embedded coordinate data are then loaded into your current Rhino model, positioned and scaled according to the settings you chose.
In summary, importing coordinates often means importing a file that contains them. Rhino's import dialogue provides controls to manage the scale and orientation of these coordinates to ensure the data is accurately represented in your project space.
