# In 3D

Every planex2d object lies on a plane in 3D. `px.Plot3d` draws faces, shapes, wires and sketches on their planes in
one 3D view that can be rotated and zoomed, together with OpenCASCADE shapes. This shows where a profile sits on a
part before it is extruded or cut. Every object also has `.Plot3d()`. In the view:

- a face, shape or wire is drawn on its own plane;
- a sketch contributes its drawn edges;
- a `px.Plane` is drawn as a square with a line along its h axis, with `plane_size` as its side;
- an OpenCASCADE shape is drawn as it is.

`Plot3d` draws with ngsolve_webgpu by default, and with netgen's webgui when `backend="webgui"` is given.

The example is a plate of 4 × 2 with a hole, a copy of it turned upright about the x axis and lifted by 1, and an
OpenCASCADE box of 1 × 2 × 1 beside the plate:

```python
import netgen.occ as occ
import planex as px

part = px.QuickSketch().RectangleC(4, 2).Face() - px.Circle((0, 0), 0.5).Face()
upright = part.Rotated((0, 0, 0), (1, 0, 0), 90).Translated((0, 0, 1))
box = occ.Box(occ.Pnt(3, -1, 0), occ.Pnt(4, 1, 1))
px.Plot3d([part, upright, box])
```

netgen's meshes of them.
