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

It calculates flat (unfolded) sheet development of ducts, rectangle to round transitions, cylinders, cones, intersections, connections, Ys, elbows, etc. For HVAC, hoppers, cyclones, ducts, silos, etc.

It is an advanced, complex-shape, mathematical drawing tool for Autodesk® AutoCAD®, that draws complex shapes (either 2D curves, 3D curves or 3D surfaces), that are not available as AutoCAD commands

Polyhedral Mesh to Solid is for that difficult Mesh, which won’t convert to 3D Solids because of self-intersecting faces etc. It also locates the Center of Mass for a single or a group of objects.

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

App to quickly copy a rectangular window of selected objects out from your drawing, and trim everything outside the window's edges. The result can be copied to the current drawing or to the clipboard.

This app can be used to select entities based on the properties of the selected sample entity. All supported properties of the entity will be displayed in a DCL box.

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

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

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

DWG/DXF Compare plugin compares two drawing files and the comparison result is shown in a new Autodesk® AutoCAD® window.
