Nodes, restraints and calculated translations

Fixed translations are zero. Reactions are shown only in restrained directions. An absent result is never replaced with a guessed displacement.

CLT LAYERS / GEOMETRIC INSPECTION

Look inside a layered panel.

Rotate the layers, inspect a window opening and check the net timber volume. These are geometric quantities; this view does not calculate CLT structural response.

Geometry only

Opening coordinates start at the panel’s bottom-left corner. All four edge ligaments must remain at least 1 mm. The opening passes through every layer.

Layered CLT panel with 3 layers and a through-window openingOrthographic geometric projection. Alternating grain directions are indicated by lines. Panel width 3000 mm, height 3000 mm, actual total thickness 105 mm. Layer separation is display only. Use the orbit and tilt controls to inspect the model.
Actual thickness
105 mm
Net panel area
7.32 m²
Net timber volume
0.7686 m³

Gross area 9 m² − opening 1.68 m². Net volume = net area × sum of actual layer thicknesses. Surface partition lines around the opening are drawing divisions, not timber joints.
