The commercial, registered version of 2DSHEET may not be duplicated other than for backup purposes. A registered copy of 2DSHEET must be treated like a book, in that the same registered copy of 2DSHEET may not be used in more than one computer at the same time, just as a book may not be read by more than one person at the same time (without making an illegal copy). 2DSHEET is property of Juan Mario Lavric and you're bound by the terms of the license agreement by using this program.
Registered users of 2DSHEET can get the current version via E-mail, mailed notification of major 2DSHEET updates, and priority when calling the E-mail (we guarantee no support to unregistered users).
Most importantly, registered users know they are helping to make sure that high quality software like 2DSHEET continues to be sold in this low-cost way.

2DSHEET is copyrighted software. (C) 1998 & 2001 by Ing. J. M. LAVRIC. Other brand and product names are trademarks or registered trademarks of their respective holders.
This is an AutoLISP program for 2D sheet metal, running in AutoCAD 2000, R14, R13 or R12, implemented with DCL dialogue boxes.
One drawing unit stands for one millimeter.
The program can perform the following:
The program draws the resulting profile with its bending radiuses and calculates the unfolded length. (3D developments are drawn directly).
When the program starts, you are also asked for: sheet thickness, inside bending radius (or width of punch; thus the program calculates the resulting radius).
You are also asked for a correction factor (which is normally 1.0; look further for more details).
Until you register, you have limited options: The polylines shall not have any arc segment (just linear segments). This software is shareware and you are encouraged to register it if you use it more than 30 days.

Registration fees:
$40.00 US if cash payment (*)
$50.00 US if cheque payment
$15.00 US each additional site license
Payment in US dollars can be by cheque or money order.
(*) In some countries it may be expensive to obtain cheques in US dollars. Therefore I will accept US cash dollars in a letter. Make sure the letter does not feel like it has cash inside.
Please allow 2-4 weeks for processing.
Send payment to: (see updated address and other data), providing the following information: e-mail address, program to register [2dsheet], payment method and number of additional site licenses.
2DSHEET consist of the following files:
2DSHEET.LSP
regstred.zip (*)
2DSHEET.EXE
2DSHEET.HTM (this file)
2DSHEET1.GIF
2DSHEET2.GIF
2DSHEET3.GIF
2DSHEET.SLB
2DSHEET.DCL
acad2000doc.lsp
acadr14.lsp
acadr12.lsp
2DSHEET.DWG (a R12 file with some examples)
(*): regstred.zip is a password-protected zip file that contains the fully working (registered version) of 2dsheet. When you register, you will receive the password to decompress it.
Remark: This list is not to be regarded a comprehensive one. Some other files might be included.
The easiest way of installing 2DSHEET is to copy all the files to one of the defined AutoCAD path search directories:
for example in C:\ACADR12\SUPPORT.
(In the same directory that DDMODIFY is a good place!)
The program is loaded by typing the following in AutoCAD's command prompt:
(load "2DSHEET")
(the parentheses and the quotation marks shall be included). Press enter.
Remark: An automatic loading was implemented. The corresponding acad*.lsp file shall be copied in AutoCAD's SUPPORT folder. The file shall be selected from the ones provided depending on the AutoCAD version: acad2000doc.lsp for AutoCAD 2000, acadr14.lsp for AutoCAD R14, etc. The original file should be kept (change the name of the original file: for example acad2000doc.old, acadr14.old, etc.).
The automatic loading will be available the next time AutoCAD is started. To load and start the program type:
2DSHEET
(and press ENTER) in AutoCAD's command prompt.
An alternative for AutoCAD expert users: Add the following line in the ACAD.LSP file (for example: ACADR12.LSP). This file is generally located in the SUPPORT folder:
(autoload "2DSHEET" '("2DSHEET"))
To start the program type:
2DSHEET
(and press enter) in AutoCAD's command prompt.
To run the program type 2DSHEET in AutoCAD's command prompt (refer to the previous section for shortcuts).
If you have not registered yet, a dialogue box appears asking you for a REGISTRATION KEY (PASSWORD).
Important: Some options will not be available until you register: The polylines shall not have any arc segment (just linear segments). This software is shareware and you are encouraged to register it if you use it more than 30 days.
Enter the thickness and the inside bending radius (if you enter the width of the punch, the program will calculate a bending radius; although the bending radius depends of the mentioned width, it also depends, in a smaller degree, of the shape of the tool and of some other factors. Our experience is, that such is a good approach).
The already mentioned correction factor is for correcting the unfolded length. The so called neutral fiber (for calculating the unfolded length) depends of the bending radius and of the thickness, and sometimes of the material. The program considers the use of steel (correction factor 1). For other metals, some correction might be needed.
Next you can choose among the following options:
If you select picking a POLYLINE, pick one (representing one side of the sheet), and then select the other side. The result of this process will be two parallel polylines and some texts representing the partial lengths of the development. Finally, the text showing the calculated unfolded length is printed. The round off can be selected (0.1, 0.2, 0.25, 0.5, or 1.0 mm).
![[Dialogue: 2D Profiles - 5 KBytes]](2dsheet2.gif)
If you select to draw a parametric profile, another dialogue box appears showing the profile (select one using the 'next' and 'previous' keys) and asking you for the parameters. After that the profile is drawn as in the previous case.
![[Dialogue: 3D Bonus Developments - 8 KBytes]](2dsheet3.gif)
Finally there is a bonus: some very common 3D developments: Cylinders and cones, shoe branches, segmented bends and angled branches. Thus another dialogue box appears showing the 3D developments (just select one using the 'next' and 'previous' keys) and asking you for the parameters. After that the development is drawn.
In the case of cones (cylinders) the whole development is drawn.
In the case of angled branches a half of part is drawn (Consider that when the program ask you for n (number of parts, it refers to the number of whole parts; do not count the 2 halves at the ends as 1!)
In the case of shoe branches the half of the development is drawn (being symmetrical).
In the case of angled branches, the whole development is drawn.
