About this block

The source title, Dôme sur pendentifs et arcs doubleaux, describes a dome carried on pendentives and stiffened by transverse arches, and the drawing shows exactly that: two bay elevations with grey masonry coursing on the piers and voussoirs on the arches, and a square plan filled with concentric red circles that describe the dome shell. Cyan construction lines and 119 construction points remain in the file, alongside 177 lines, 12 circles, 9 arcs and 5 hatches, all on layer 0. The sheet spans about 1,790 by 2,240 units in millimetres.

This is a teaching drawing for vault geometry, useful when restoring a domed bay or preparing a stereotomy study. Trace the plan circles to set out the shell in your own drawing, and use the elevation coursing as a guide for stone joint layouts. Scale by 0.001 to bring it into a metre-based drawing, and put the construction points on their own layer before printing so they can be turned off.

Questions

What are arcs doubleaux?

Transverse arches: the arches that run across a vault or dome bay and carry its load to the piers.

Are the construction points useful?

Yes. The 119 points mark arc centres and setting-out positions, so you can snap to them when rebuilding the geometry at another size.
