Hi, my name is Juergen Riegel and try to make a QT Viewer Widget for OpenCasCade. I have some experience with CasCade on NT and tried the same scheme to bind a Xw_Window to a existing Xwindow of a QT Widget. But it didn't work so far. Here's what I did; In the Application: // Graphic Device from def
Hello, I am studying for a Phd at Loughborough University and am considering using Open CASCADE for the development of an application in the area of assembly modelling/tolerance assignment to be integrated with Dassault Systemes/CATIA software. The requirements for Open CASCADE on an NT platform inc
Hi, My name is Jens Kilian and I'm interested in porting Open CASCADE to the Be Operating System (BeOS). In a previous job I worked on a similar application, but I'm doing the port in my spare time. I've downloaded the code and am in the process of getting the Foundation Classes to compile; there ar
What is the underlying form used for storing geometric data? Is is Bezier, rational Bezier, NURBS, a combination or something else? I know the conversion to NURBS is fairly trivial. Can you work completely in NURBS? Or do you have to convert to bezier (in the case of NURB geometry coming from an ext
I have written a simple program to create a PGeom_Line. I am interested in saving this to a file. I have the following code for this -> -------------------------------------------- void main(int argc, char *argv[]) { Handle(Geom_Line) aLine; aLine = new Geom_Line( gp_Pnt(10.0,10.0,10.0), gp_Dir(0.0,
I have seen a banner on the Open Cas.CADe site advertising for C4W www.c4w.com a very impressive suite of tools with data-exchange named 3D-Shop, viewer, surfacing capabilities, COM components, a development environment to deliver plug-ins. It is not open source (it is Windows only) but not very exp
Hello, Kindly check a) whether you have downloaded from Unix machine or not and b) file size. I faced this type of problem when Browser on WinNT was used. But the browser on Linux machine was used, the file size was OK and hence tar / gunzip. Balasubramanian
Tclreadline is a gnu readline extension to tclsh and wish. It allows users of the tcl shells to access command history via the up/down arrow keys and other special behaviors ala' bash and numerous other gnu softwares. I have found using tclreadline with the opencascade Draw package as a simple way t
I'm pleased to inform you that a new Linux version of the Shape Viewer application correcting the Hidden Line Removal bug has been published. You can now click on the second icon on the right most icon stack in order to turn the Hidden Line Removal mode on. This correction, as well as other correcti
J'ai commence avec une petite application, le ShapeViewer...I know, in English ...I started with a small application, the Shape viewer. I loaded a brep and got a nice wireframe. But if I hit the second icon on the right most icon stack, I get the error below. Other functionality seems to be disabled
Has anyone else tried running the "Draw" test harness program? When I try to run the demo program as stated in the sourceREADME file, I get the following output in the text window: (used "script" command to capture") Script started on Wed Dec 29 15:34:30 1999 [root@bobslap1 DrawResources]# ./demo Dr
When I run the LinuxSampleTopology demo on redhat 6.0 with Jave JRE 1.2.2, it crashes with a SIGSEGV and I get the stack trace below. Has anyone else seen this?

For each compilation I got a message like: XX.so linked pg++: no input files XX.so check Error(s) When I try the demo I got the following message: limit: coredumpsize :Can't set limit. What's wrong and what can I do to got the thing f
I can't find any set_env.csh file in the CAS3.0 directory (I have downloaded the source version). Should I set a JDK variable and recompile all the files? Thanks. A.Bertrand
Does anyone know the if/when the data exchange toolkit will be published ? I'm interested in importing trimmed IGES surfaces. Does anyone know how persistant objects will be done in OpenCascade ? In the old Cascade it was done with Object Store. Thanks
Hello, Is there any plan of making Open CAS.CADE availabe on the SGI-IRIX platform. If we wish to port it on SGI what are the pitfalls and what needs to be taken care of. Thanks
Hi all I was wondering if someone can answer a couple of questions about the upcoming Open Cascade release: 1. Does it support non-manifold models (general combinations of solids, faces and edges)? For example can two model regions share a common face? or can there be a face partially jutting into a
I'm very interested in the open-sourcing of the opencascade libs. However I'm wondering what the possibilities will be for developing apps and what we'll actually be able of doing - will we for example be able to create (easily) a CAD platform for linux/unix or will it only serve best as a library t
Hi! Has anyone had any problems with running release version using CasCade2.1 ? Everything runs fine till we use debug version (we have get rid of asm int_3 by using attach to debugger function), but in release build we are getting OSD_AccessViolation just after SEGVWntHandler SIGSEGV without any sc
