[Original report](https://bugs.launchpad.net/bugs/1794324) created by **eelik (eelik)** ``` This is a wishlist item which would require a change to the footprint file format. I would like to have an ability to add a simple parametrized box (or other very simple object) as a 3D model for footprints. It would be an alternative to the external 3d file. The parameters would be saved along with the footprint. The parameters would be: x, y, z dimensions and rounding (chamfer) radius in each direction. Maybe also color. That would be enough for visualizing the board roughly, either in the 3d view or in a step model for physical dimensions. This could be a huge space saver if someone doesn't want to download the 3d models. It would also help when a model isn't available. It could also make projects really standalone without 3d files if exact modeling isn't needed but the 3d view still wanted. ``` 2020-09-29 addition (JE): We should support a few parametric model generators that will result in valid STEP export as well as 3D preview inside KiCad. The easiest way to do this would be to take a closed shape (in the 2D editor) and convert it to a 3D model by an extrude operation. The user just has to draw the shape (rectangle, circle, or even some complex polygon) and specify the height to extrude by.
