This program allows the user to quickly fill out block attributes based on information saved in a text file. Block names are ignored. Only attribute tags are considered.

Unfolds sheet metal elbows and cylindrical segments. A segment is part of a cylinder intersected by two arbitrary planes.

A cylindrical pipe intersects into a cylindrical pipe or a cone-shaped pipe. Unfolding (developing) of the parts (cylinders and cones). Allowances may also be left for fastening.

Sheet metal pipes need shaped elements. Three types are presented here: transition from rectangular to circular section, straight reducing cone, and eccentric reducing cone.
