Shell

Key H.

The shell took out the material inside, leaving walls of 2 mm; the top face was picked to be open.
The shell took out the material inside, leaving walls of 2 mm; the top face was picked to be open.

The body becomes hollow: the material inside is removed, the walls get the given thickness, and the faces you pick disappear — the hollow opens through them.

How to do it

  1. Press Shell and click the faces to open (one or several).
  2. Type the Thickness at the geometry; in the bar above — where the wall goes: Inwards, Outwards or Centred (half each way).
  3. Enter applies, Esc cancels.

Order in the timeline

A shell goes after the main shape but before small fillets: then the fillets land on both the outer and the inner edges.

If it did not work

The thickness is not taken — in a narrow place such a wall does not exist: no material is left. Make the thickness smaller; the reason is written at the field.

For an even wall along a flat contour rather than over the whole body, see offset.
