Light Distribution distributes the lighting fixtures in a room according to the rule that: the distance between the elements is twice the distance between the elements and the walls of the room.

With Chaos, you can randomly distribute Points or Blocks in the drawing using a sizable Brush.

Tanks3D includes five vertical tank styles and three horizontal vessel types. The program has a simple dialog box interface allowing the user to specify the dimensions.

Lisp allows continuing drawing Polyline, 2D polyline, 3D Polyline, MultiLine, or Line starting from the selected end.

SURVEYflow automates key survey creation tasks such as adding coordinates, levels, and areas. It adds doors and trims walls, includes a tailored layering system, and content libraries.

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.

Commands for moving or copying objects in different UCS that are set dynamically. Finds the intersection points of lines with a plane, cylinder, cone, or sphere. Draws a chain sprocket and spur gears
