But he wrote it himself. I assumed the OP was talking about some of the collaborations that have been mentioned here in the past. Nothing has ever come of those. And I was only talking about projects here. I'm aware that there are plenty of open source projects that get completed. __________________ Gerry

I thought all "jabuffi" was looking for was cnczone specific projects, only (also).

Anywho ...

Spiro was a one man project, but spalm still left it open for anyone to add to. Which is a good start for a larger project.

Initially I was, but after it became apparent that this forum had typically not gotten past the idea stages, I branched out and started proposing my own ideas... I'll admit I'm a sorry programmer too, but I still think it would be neat to use OpenCacsade as the basis for a powerful opensource application supporting both CAD & CAM... Dan, what "studying projects" were you reading about it? I'd like to see those...

[Dan Falck]

Here are a few Opencascade projects that I know of:

http://sourceforge.net/search/?type_...ds=opencascade

http://lignumcad.sourceforge.net/doc/en/HTML/index.html

http://cam.occ.googlepages.com/home

Dan- Thanks for the links. I've seen Cam.Occ, and I'll look into the other two...

Really obvious question (doing 3 things at once, so I'll ask it just in case someone answers before I have time to find it...) : Is OpenCascade written with the intention of being run in Linux, or something else? The reason I ask, if it were then that fact would greatly enhance the option of perhaps coupling it with EMC...

Wayne-
I think your previous reply on setting up a section code modules would be great! For now we could just start a string dedicated to that, just to get the ball rollin'...

Opencascade is open source and is currently set up for Windows and Linux. I run it under Ubuntu Linux.

Dan-

I'm curious: What do you currently use it for?

[Dan Falck]

I'm running and studying Opencascade, mainly to see how it's done. I am just a novice at it.
The guys who are writing the software in the links that I put up earlier can tell you a whole lot more about it than I can.

I am playing around with python programming and have found that I can write little scripts that can control larger programs in C. I have also taken other people's python programs, modified them and learned enough to be dangerous
If you want to check out a simple, but easy to understand python CAD type application, check this out:

Doug made it really easy to understand how a CAD program can be written. I have been hacking it to extract entity data, in the hope to use it for CAM. I'm starting to make progress.

Hi, I'm the guy writing cam-occ.

The OCC libraries contain much code that can be used in writing a CAD or CAM program, but it is *not* a turn-key, ready to go solution. (Not sure what you mean by "capability" - much of what you need is there, you just have to figure out which pieces to connect, and in what way.)

I wouldn't call the code clunky. It was good enough that Dassault bought all rights to their then-current version of Euclid, as well as Strim. Matra retained rights to all previous versions of Euclid, and then released this code as OpenCAS.CADE. Some of it is documented in French, so the code itself isn't alwasy easy to read - but they provide quite a bit of documentation in the form of pdfs and doxygen html.

It has a fairly steep learning curve which is offset by the demo programs they provide. (Alas, I have not figured out how to build them on x86-64 linux)

Originally Posted by jabuffi If my above two suppostions are correct, then what we need (in my opinion) would be to integrate OpenCascade into a higher level program (probably similar to what Dan's post illustrated) that could simplify use of the sourcecode... I'm thinking something that lets one draw intuitivly (Think easy like SolidWorks)

Heh... and I thought plain CAM was hard. I think something that lets you draw as easily as a professional package will be more difficult!

OCC does contain one demo of interactive 2d drawing, using Draw Harness. It's contained in CASROOT/ros/src/DrawResources/PROFIL.tcl . It's broken in occ6.1. If you want to try it, start DRAWEXE. Type in pload ALL and then source PROFIL.tcl

Originally Posted by jabuffi but translates back to what the source code needs. Second, it would allow for additional blocks of code to be input to do random things, like Wayne's suggestion (think "Add-Ins" in Excel). This way one could have a powerful solidmodeler with capability to perform a cam function after design is complete, output g-code to a machine, and allow for addition of opensourece modules like Spiro... A full, opensource solution for the entire gambut of Cad & Cam. Thoughts????

Sounds good, but CAM itself without any modeling capabilities is difficult enough for me
