Solids and meshes in the webgui

netgen’s webgui draws the OpenCASCADE solids made from planex2d faces and the meshes that netgen makes of them, which can be rotated, zoomed and clicked on to identify faces and edges. See In 3D for drawing planex2d objects themselves on their planes in 3D. The example is a plate 4 × 2 with a hole:

[1]:

from netgen.webgui import Draw
import planex as px

plate = px.QuickSketch().RectangleC(4, 2).Face()
part = plate - px.QuickSketch().Circle(0.5).Face()

Solids

The plate extruded by 0.5 with OpenCASCADE:

[2]:

Draw(part.ToOCCShape().Extrude(0.5))

Meshes

The solid meshed by netgen with curved elements:

[3]:

mesh = px.OCCGeometry(part).GenerateMesh(maxh=0.3)
mesh.Curve(3)
Draw(mesh)

On a plane in space

When the plate is turned by 60° about the x axis and lifted by 1, its export lies on that plane.

[4]:

Draw(part.Rotated((0, 0, 0), (1, 0, 0), 60).Translated((0, 0, 1)).ToOCCShape())
