About this block

The source, Dômes sur pendentifs avec pans coupés, compares two domes whose supporting square has its corners cut off, giving an octagonal transition. Two elevations at the top show the shells drawn with 127 ellipses over arched openings, one bay wider than the other; two plans below show the chamfered corner piers as grey hatches with the dome circle inscribed. The file has 426 entities on layer 0, including 87 construction points and 11 hatches, spanning about 1,850 by 2,190 units in millimetres.

This is the drawing to consult when a square room needs a dome but the corners are chamfered, a common condition in hammams, mosques and Beaux-Arts halls. Trace the plan with the pier width that matches your structure, then reuse the elevation to draw the shell in section. Bring it into a metre drawing at a scale of 0.001, and move the construction points onto a frozen layer before plotting.

Questions

What are pans coupés?

Cut or chamfered corners. The square bay under the dome has its corners cut back, so the dome ring meets an octagon rather than a square.

How many dome variants are drawn?

Two. Each has one elevation and one plan, arranged in two columns on the sheet.
