This app helps you save a lot of time to select objects by quickly making filter and quickly selecting similar objects based on sample entities.

3 tools in 1 app. The easiest way to get total Area and Length or Perimeter of objects. Export result to clipboard or put to text objects

Application that draws dynamic coordinate grids linked to closed polylines.

Joins and cleans-up polylines and line entities to create closed boundaries and to close gaps not seen visibly.

Universal tool for calculating total lengths and total areas of polylines

Plugin for calculating total lengths and total areas of polylines

Creates multiple-types of 3D screw and/or fastener hardware with a variety of head types in Imperial and Metric units. It comes with built –in post processing tools for block modifications.

Joins adjacent polyline, line and arc segments to create (or convert selected line objects) into closed polyline objects

Creates multiple-types of 3D screw and/or fastener hardware with a variety of head types in Imperial units.

Creates a 2D or 3D spring object from user-input; Height, Pitch, Diameter and number of Coils

Searches the minimum distance in a design, finds design errors, and will flag on-screen plus list the minimum distance value and X/Y coordinates

Display the degree angle of selected LINE or POLYLINE entities in either Decimal or Minute values based on a selected ‘base line’

Parametrically creates a radial type grid useful for drafting needs that require precise angular grids.

Adds a vertex to polyline segment(s) and snaps it to a specific degree angle, to one of: 10, 12, 15, 30, 45, 60 or 90 degrees

3 Function App to create multiple layer groups to turn on one group/Batch and turn off others

Checks for and identifies closed polylines with outward or inward facing acute angles (less than 90°) and draws pointers

Application for Autodesk® AutoCAD® for shop detailing of structural concrete and steel structures.

Linked Alignments Manager to set dynamic links.

This program calculates the offset distance of multiple points to a straight line consisting of an alignment (polyline). Handles easily 1000k points in .txt formats.
