Length, Area, Volume and Unit conversion for Autodesk® AutoCAD® objects.

Replaces the object linked to a field preserving all the other field's settings.

Calculates the Total Length of multiple objects of selected type(s).

This plug-in can be used with Autodesk® AutoCAD® to quickly collect the area and length of a group of selected polylines grouped by layers.

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.

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.

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.

Powerful application for designing electrical parts of street lighting installations. It fully automates all electrotechnical calculations, computations of specifications and drawings of schemes.

QuickAreas is a handy add-in for Autodesk® AutoCAD® that retrieves the area property of multiple polylines and inserts a label with its associated area value.

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.

Dynamic block that makes drawing reinforcement sections easier. Not transparent.

Rebar Distribution is a dynamic block for Autodesk® AutoCAD® that makes it easy to display custom length, pitch, diameter and distribution length of reinforcement bars.

Poly-U includes 67 kinds of mathematical formulas, gradient curves between curves, influence curve, quadrilateral mapping, curve optimization, associative curve, inner and outer contours, etc.

10 commands in a single click. Heads up Display for Autodesk® AutoCAD® & verticals.

Add, Delete Attribute for all blocks in drawings with one click.

Triangulation creates a SubDMesh, Polyface Mesh or 3D Solid from a set of points using a Delaunay triangulation algorithm.

Create dynamic cross-sections of the ground level.

This app makes drawing trial trenches easy and uniformly.

Download topographical data from the Dutch BGT and parcel data from the Dutch BRK. (Within the Netherlands).

Search multiple drawings for blocks or texts, grouping and counting them based on their attributes. Results can both be inserted as a table or exported as XLS workbook. Table tools included.

3dS simplifies connecting beams, sizing plates and bolts. It also produces fully automated overview and workshop drawings. Use 3dS for steel structures in industrial buildings, housing, offices, etc.

Generates 3D model from cross-sections and unfolds it into flat pattern.

OneNote Add-in for Autodesk® AutoCAD®. Take notes right alongside your drawings!
