Modell and visualize a glass by Brian James

Use template files: starting point for object dimension and units (we use small objects-centimeter) + draw first cylinder

Select top face and scale: CTRL+SHIFT+left click and scale uniform

Shell object to give thickness: shell (Solid tools + CMD) and draw waterline in ghostview

Round edges of 3d model in shading view (is not a fillet in 3d object): Panel “Properties/Edge Softening

Visualization with raytracing add Material: Panel “Display/displaymode raytrace” + Panel/Material/new material glas (Drag/Drop)

Create liquid with Boolean: draw bigger box in X/Y dimension than glass as overlay + CMD “Boolean difference (DeleteInput = NO) + scale liquid to avoid overlay artefacts for right refraction

Add water material with right refraction to object: add custom Material with transparency = 0 and refraction “water”
