This plug-in puts together a collection of parametric functions for general-purpose profiles (L-shape, U-shape, square, etc.) and commands that will allow you to convert polylines in sheetmetal sections or waterproofing membrane. The commands can be accessed through an integrated tool palette, through its ribbon bar panel or through the traditional command line.


The palette will remember previously used parameters for further quicker selection and will allow to visually changing the insertion point relative to the shape.


The sheetmetal command allows you to specify thickness and bending radius and will work on simple polylines or even already converted sheetmetal shapes, allowing you to change parameters on the fly.


All functions, if applicable, allow you to draw only the external shape, or complete it with section xhatch and/or axis.


Entities will be drawn on specific layers, that users may freely choose and configure.


This software is free and will remain free. However, you cannot sell or distribute it for profit, nor you cannot decompile and use the code without explicit agreement with us.

Beware! This is the final release. There won't be any updates for 2023.
Thank you for all the support during the past years!

    I can't move on to a new version of AutoCAD without it!

    it seems that I have problems with autocad 2020;

    the created object appears offset from the point of origin where the cursor is

    Massimo Cicognani | agosto 27, 2020

    Hi, the origin should match the red dot position on the sample picture. You can change the relative origin clicking on the picture. May have you done so without noticing? However, write me at with detailed information and we will look into it.

  • I love it!
    Alberto Venturini | junio 27, 2015 Descarga verificada (¿Qué es esto?)

    I really love sheet metal function! I don't understand why Autodesk don't implement this set of function in AutoCAD like a standard command! Just a little note... membrane command should have a linetype generation enabled.

  • Membrane doesn't work with acad2014-ADT
