Hi! I am using BRepAlgoAPI_Section to find the section of 2 shapes. Then I connect the edges to closed wires. What I want to do now is to color the surface of the section. I think I could use BRepBuilderAPI_MakeFace with a Geom_Surface and a wire. My problem is how to find the face on which the wire
Hi all, I am trying to use OCC6.2.0 on Linux fc8 x86_64 ./configure --with-tcl=/usr/lib64 --with-tk=/usr/lib64 CFLAGS="-m64 -D_OCC64" CXXFLAGS="-m64 -D_OCC64 -ffriend-injection -fpermissive" make and make install seems ok. testing DRAWEXE I have the following results : - DataExchangeDemo.tcl is ok -
hello everybody: I have an application dévellopé in MS2005, as using the librairie of open cascades. to \" explore the entities topological, geometric cotopoligique,et Geometric of a model BREP \" , I want to compile this application with BorlandC++ builder6.0, to make this i use the DLL method for

Hi all, I've just reinstall OpenCascade 6.2.0 on my KUbuntu 8.04 laptop, and try recompile some of my projects. I've also switched to Qt 4.3.4 (and so for qmake), and g++ 4.2.3. I get linking erros when rebuilding my shared libraries that rely on OpenCascade, for example : "undefined reference to `V
can anyone please tell me how to dipslay coordinate system under OCAF? thanks Eric
Hi, I have got a problem that I think it will be very easy to solve for you. I have got a hierarchical structure like grandfather, father and son (All of them as TopoDS_Shape). To get that, I have created a compoundSon (with son), compoundFather (with father and compoundSon) and compoundGrandFather
Hi, Does anyone know how to calculate vertex normal after triangulation? I have fond that the class BRepMesh_Discret has a function "Normal", does it works? Any help will be appreciated!! Thanks in advance !! Yilin
Hi guys, need your help. I try to create a partial cone surface. And I use the following codes. I always got error . The shape looks: a perfect cone surface trimmed by three curves, so I can get a shape similiar to a triangular shape. Any help will be appreciated. thanks a lot. eric BRepBuilderAPI_M
We wish to generate the skin surface from a sheet metal part with thickness, the thickness is known and can be input as a parameter, how can I get the skin surface in opencascade?

Hi ! (I use VC++ and MFC) I have a number of different "cameras" in my application and when I switch from one to another I use SetEye() SetAt() and SetUp() to modifiy the view. The problem is that the view flashes a lot when I do this, it looks like these commands update the view on their own before
Hi, is it possible to define two surfaces and connect them to build a solid? E.g. can I define two circles that have no point in common and then build a cone-like solid by connecting the circles? If yes, could you outline a strategy to do this? Thanks a lot in advance.
Hi, I read a IGES file by XDE, and I add all top-level shapes in a compound , then I use BRepBuilderAPI_Sewing to sew this compound. Now I want to retrieve all top-level shapes again from this sewed compound. Does anyone kowns how to do this? Is it possible to retrieve the shapes from a compound? Th
Hi there! I'm trying to 'collect' a list of shapes. for this i use: ______________________________________________ void CGruppen::AddPartsToIGES(TopoDS_ListOfShape& shapelisthelpers, TopoDS_ListOfShape& shapelist) { TopoDS_ListIteratorOfListOfShape iter(shapelist); //////////////////// here the erro
Hi all, I'm loading an iges file with IGESControl_Reader, meshing each face in the shape with StlTransfer::BuildIncrementalMesh and triangulating with BRep_Tool::Triangulation; visualization is done in my own app. It seems to work quite good, but with a problem; vertex of triangles do not match alon
Hi guys, below is the piece of codes I use to export a face for testing purpose. I have inserted into the sample: topologybuilding to export PinkFace in that sample. However it doesn't work. I tried to trace it, but the codes is too much convoluted, I have no idea why it is wrong. Could anyone pleas

Hi, all I'am trying to read STEP file using XDE. First, I get all top-level shapes, and one of them is a reference of another assembly. so , I iterate all components of this referred assembly. My problem is that the locations of these components are incorrect. I've tried to affect all components wit
Hello, I believe I have found a bug in OpenCascade 6.2. I am able to load a large STEP model into memory without errors, but when I try to write it back out to disk, the following happens: This is my code: STEPControl_Writer writer; writer.Model( Standard_True ); ...

One behaviour which was not happening with Cascade 2.0 and now appears with 3.0 : Objects are clipped in 3d Viewer. I've tried to play with myV3d_View->SetZClippingType(V3d_SLICE); OR myV3d_View->SetZClippingType(V3d_OFF); no change at all. What was the change with viewers ?
I have created an application, but there is a slight problem with the viewer i.e. the objects displayed such as a line is partly truncated/cut-off. Why am i having this problem and how can i rectify this problem? my source...no clipping V3d_TypeOfZclipping oType = V3d_OFF; _V3dView->SetZClippingType
Hi community! refering to site 30 of the XDE guide: Can someone give me someone a simple example how i can make 4 Shapes to 2 assembly's?? Because i can work it out with the 40 sites of the guide and i read it now for 2days... thanks in advance Author
Hi, I am trying to build a compsolid from 2 solids of 6 faces that share a face. The result should be a TopoDS_CompSolid consisting of 2 solids and 11 faces. I create each solid by sewing the faces together. How do I do to combine the solids in such a way that a compsolid is created?
