Reverse Engineering

I couldn't find this "Click on menu item Tools > Reverse Engineering > .NET Framework". I have that Tools menu, but not Reverse Engineering. I have 6.20.4908.40804 version. Is it moved to somewhere else?

Thanks for the help!

RE: Reverse Engineering

From version 6, Software Ideas Modeler is available in 3 editions - Standard, Professional and Ultimate

Reverse Engineering is not available in Standard edition, only in two higher ones (Professional and Ultimate).

generate uml diagrams

I want to generate UML diagrams like activity, use case, and others from c# source code, but I couldn't do that in trial version I have

can I know why?

RE: generate uml diagrams


Currently, Software Ideas Modeler supports generation of class diagrams, package diagrams and entity relationship. Diagrams can be generated from database, from source code (various languages) or .NET assembly. Other diagram types can be drawn only manually.

Reverse engineering

How can I convert C++ text files (*.h *.cpp) to classes? It's possible?

RE: Reverse engineering

It is not possible in the current version, but it will be very likely part of the version 5.

RE: RE: Reverse engineering

Two questions:

Will you also allow in .NET like C# (*.cs) and VB (*.vb) classes along with their methods from the source code?

From those, will you also be able to generate other diagrams like sequence (from what the methods call other methods themselves) and activity diagrams?

I'm very interested to see if you're able to do that with your next version. It would definitely be helpful to trace out threading issues

Dusan Rodina - 15 February 2011 19:57:27

RE: RE: RE: Reverse engineering

Source code processing of C# and VB will be supported.

It is still questionable whether the next version will be able to generate sequence and activity diagrams. In any case, I added it to my list of requirements.

Im guessing that the same is true for SQL2008 tables?

Dusan Rodina - 17 November 2010 13:59:22


You can import your tables from database using menu Tools>Reverse Engineering>Database. MS SQL Server 2008 as source is supported.

Do you planing include in support othes DBMS, for example Oracle, PG, MySQL or Hierahic DB?

If YES, when you planing do it?

Dusan Rodina - 29 May 2011 16:19:57


I'll try to include the support for them in the next major version 5.

Dmitry 29 May 2011 23:42:26


Thank you very much. I'm don't hope that this possible as soon.

Roger 17 November 2010 16:37:15


Hmmm. must be something I'm doing wrong then. It doesn't appear to work for me.

RE: SQL2008

Thanks for details, I will check it out.

EDIT: Version 4.80 solved this problem (at least for me).

doesn't work

This would be great if it actually worked, but it doesn't ?

RE: doesn't work

I've probably the same issue. The assembly is .NET 2.0, but the "Import Object Model" window has only the root element of the tree. No namespaces or classes ale loaded. I find the problem is in Debug/Release compilation. The Release version loads only the namespace, Debug version loads nothing.

Dusan Rodina - 1 March 2011 0:18:09

RE: RE: doesn't work

I will do some other tests and try to find out where is the problem. It will be fixed as soon as possible.

Dusan Rodina - 15 November 2010 21:38:19

RE: doesn't work

It doesn't work with .NET 4.0 assemblies, because of binary incompatibility of .NET 4.0 with previous versions of .NET. I will try to bring support for .NET 4.0 in the next major version of Software Ideas Modeler.

Aurino 24 March 2011 23:36:59

RE: RE: doesn't work

Do you know when .NET 4.0 assemblies will be supported? I'm using the last version and it doesn't work yet.

Dusan Rodina - 24 March 2011 23:48:46

RE: RE: RE: doesn't work

Very likely in version 5.
