Designing in Roof Sub-Layers

For a long time, the SEMA program has made it possible that various layers can be individually applied, processed, evaluated and made available for machine production on the top side of the roof. These functions and this freedom in planning and execution have now also been implemented for the bottom side of the roof.

In the new Version 22-3, it is now possible to cover up to twelve additional roof sub-layers under each roof area together with a construction layer, which as usual also intersects in the valley areas in order to obtain an accurate area evaluation.

In order to enable the creation of more detailed plans and detail drawings of profiles, roof layers are displayed in the vertical and horizontal sections with appropriate fillings as stored in the master data.

Layer connections to ridge and eaves purlins as well as overlying walls are executed as stored in the master data. Layers can be reworked manually at any time if desired by the user.

The soffits of existing or subsequently placed skylight windows also take into account the roof sub-layers and are calculated automatically up to the lower edge of the last roof sub-layer.

Exact evaluations of materials, areas and quantities are possible using the material list. The layers are listed individually and precisely by means of the comprehensible measurement. Correspondingly, the measurement can be recalculated easily and comprehensibly.
