In this tutorial you will learn how to create a 2D-representation of your model and how this can be edited.
Opening/Creating the 2D-Representation
Firstly, download the above model file, Fika Chair (with materials).cmsym, then import the model into Model Lab.
Switch to 2D by clicking the 2D button in the toolbar or by pressing Spacebar on your keyboard.:
The tutorial file already has a 2D-representation created, but if your specific model file does not show a 2D-representation, follow these steps to automatically create it from the 3D model:
- Expand the Level of detail dropdown menu.
- Click on Rebuild base from 3D to create a new 2D-representation based on the current Base model visible when you are in 3D-mode.
Editing 2D Nodes
- Expand the Transform dropdown menu.
Within this dropdown menu, you'll notice that it's pretty much the same as in 3D's, but with an additional Selection Elevation slider.
This slider determines the height/order of which the 2D layer is drawn on.
- Before going editing any node, we'll first have to select one. But a 2D-node cannot be selected by clicking on them in the model-view. So, we'll have to select them in the Overview.
- Go to Overview and select Layer. Then, select the layer named “A-FURN-SEAT-BSCR-01”.
- You can edit the elevation of the selected nodes by moving the elevation slider or by inputting a value.
Since the Selection Elevation setting is only available in 2D, it only affects the 2D-representation.
Adjusting 2D Level Of Detail (LOD)
There is only a single LOD for the 2D: Super.
Just like in 3D, the button will be marked with red color to indicate that the model is too heavy performance wise. So in order to adjust it:
- Click on the Super LOD button.
- Select all nodes by using Ctrl + A.
- Use the slider at the bottom of the model view to manually reduce the number of lines. Reduce the number of lines until the button is marked with a green color.
- Select nodes from Overview that you know are completely hidden to further reduce line counts.
- Select and reduce small nodes by using the Select by size found in the Selection controller.
That’s it! Now you should know:
- How to create a 2D-representation from your 3D-representation.
- Edit the elevation of selected nodes.
- Perform manual line reduction.
