Array rebar dot over line, polyline, or arc

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.

"GLTF Exporter for Autodesk® AutoCAD®” exports the model to a glTF (.glTF) and GLB (.GLB) file.

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.

PVC-40 3D creates a variety of PVC Schedule 40 Pipe and Fittings as 3D solids for easy placement in the 3D-PVC piping drawing.

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

Obtaining the section or unfolding ( developing ) of a cone intersected by a plane or the unfolding ( developing ) of a winding of a conical or cylindrical shnek is used.

Pick on a drawing entity and place text in the drawing listing the entity's area.

ID a point on the screen and label it with a Mleader.

Identify Northing and Easting of a point on the screen.

MeteorSpec LT is a toolkit for electrical designers. Analysis and design of 0.4 kV networks. Calculators for electricians and totally customizable tool for summarizing lengths and areas of polylines.
