Use PDFin to open and edit PDF drawings within Autodesk® AutoCAD® and other Autodesk programs. Ideal for older versions without built-in PDF support. Trial with watermark.

Places the Length of selected polyline segments, next to the segment as text with user-defined Height, Angle, and offset and drawing dimensions’ units.

Labels the first segment length of selected polylines(s) from the ‘start point’ to the first vertex.

Functions to find and flag vertices of unblocked and blocked polylines marked with a cross. The app will then fix and move/snap these entities to a user-defined grid-snap.

Adds, deletes and extracts entities from a parent block without exploding

View details of a block’s hierarchy and save to TEXT file.

Converts True Type fonts into user-specified vector outlines, a filled hatch or 3D Solids while preserving the original text.

Easily convert those old leaders and text to Mleaders!

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

Converts arc shapes created with multiple vectors into smooth polyline arcs.

Moves entities to the closest intersection of a user defined grid.

Convert Spline Objects, Ellipse objects, Arc objects, Polyline-Arcs and Circles into vectorized objects based on user-defined segment length.

Allows placing block(s) or duplicates of a single block, upon a selected curved or straight object plus allows the user to slide these along the curve / edge.

Converts True Type fonts into user-specified vector outlines or filled hatch while preserving the original text.

Trim lines or polylines internally or externally, using a closed boundary as the edge.

Allows users to easily arrange current layers in any desired order with a couple of picks.

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

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.

A professional version of Text Bubble. You can insert text bubbles to lines, curves, or draw leaders with it, or quickly making a schedule from text bubbles and other blocks.

You can insert text bubbles to lines, curves, or draw leaders with it, or quickly make a schedule from text bubbles and/or other blocks.

Interactively positions text characters along lines, polylines, splines, circles, arcs and ellipses.

Generates successive polyline approximations of lwpolyline/polyline3d objects to smooth out the original shape but keep the overall polyline trend.

Morphs one polyline into another by generating intermediate polylines at arbitrary stages of the process.

A simple 2D maze generation app. It can also be used to generate random hatch patterns.
