DoubleCAD User Manual : Create Surface from Solid

Enables you to convert a solid volume into a hollow form; each solid face is converted into a surface.

  1. Start by selecting one or more solids. This example uses a 6-sided polygon extruded (using Simple Extrude) into a solid.

  2. Activate the Surface from Solid function, and the solid is hollowed out. Each of its facets is now a surface. To more easily see the results, activate Facet Edit and select one of the vertical faces. (See Facet Edit.)

  3. Delete the face (using the Del key), and view the model in render mode to see the missing facet.

    Note: If you used Facet Edit on a solid, without converting it into surfaces, this would be the result - the other faces would update to accommodate the deleted face.

    One usage of surfaces is to recreate a solid from the changed volume. If you delete a few more faces . . .

    ... you can then use Create Solid from Surface to add one missing face and produce a new solid. (See Create Solid from Surface.)
