I try to import an IGES file using open cascade and get an exception The code: IGESControl_Reader reader; IFSelect_ReturnStatus stat = reader.ReadFile("filePath"); Standard_Boolean ok = reader.TransferRoots(); TopoDS_Shape shape = reader.OneShape(); I get stat = IFSelect_RetDone in the reader.Rea
We are upgrading an older version of OCC and are having problems exporting STL files. In the older code, when writing an STL file, a mesh was automatically created. In the current release, however, the StlAPI_MeshIsEmpty error code is returned. I've traced the problem to the following OCC code chang
Hello. I have asked already the same question on the user forum, but unfortunately, nobody react on it. The question relates to OCC 6.8.0 Does somebody know, if there is a way to estimate the possible size of OCAF file having TDocStd_Document object without saving it? Any suggestions and tricks are
I'm looking for some guidance on the correct way to write/read a TopoDS_Shape to/from a memory buffer. Something like BRepTools::Write/Read, but using a binary format instead of ASCII as well as being able to target a specific version. The information I found for OCAF persistence mentions a binary f
Is there any control similar to xstep.cascade.unit for the Parasolid reader (XtControl_Reader)? The bodies I am getting are scaled up by 1000 and currently need to be transformed.
Hello everyone, I'm trying to extract product names from STEP files, but, I always fail. I tried with following steps: Read STEP file using STEPCAFControl_Reader reader, set its name mode to true (STEPCAFControl_Reader::SetNameMode(true)) and called transfering STEPCAFControl_Reader::Transfer(Handle
Hi, I am trying to write a STEP file using 'STEPControl_Writer'. I am adding product names using the following command (c#) My code looks like this, /////////////////////////////////////////////////////////////////////////////////////////////////////////////// foreach (KeyValuePair<string, TopoDS_Sh
Hi All, I have an issue while using XDE. I am able to read and display .STEP assembly but not able to read component names and colors. I have tried the following code:- { Handle(TopTools_HSequenceOfShape) aHSequenceOfShape= new TopTools_HSequenceOfShape(); aHSequenceOfShape->Clear(); //Create Docume
Hi all, I finally managed to load a STEP file (with colors and labels) and export it as a VRML file using this code below. It works fine with most of the models I tested it, but there are a few models that seem to be composed of various parts that don't work. What happens is, that all parts seem to
I'm trying to use OCCT to read IGES files so I can translate them into our proprietary data format, which is BREP-based. I originally used IGESControl_Reader.TransferRoots() and .OneShape() to create an entity tree, which I parsed recursively. That works great for flat-sided objects, but it fails mi
Hi All, I am able to read and display a complete assembly (STEP) using stepcontrol. but when I try to read same assembly (STEP) with names of components, colors etc. using stepcafcontrol, I am unable to do so. Any Clues ? Thanks in Advance Shamher
I'm new to OCCT. I'm trying to use it to read an IGES file and convert it into the internal data structures of the software package that we write. I think I've figured out the code to read the IGES file into a TopoDS_Shape object. I can use Shapetype() to see which TopAbs_XXXX type this shape really
What can I do in order to make opencascade support chinese file path? Opencascade can not open file under chinese file path now .
When STEPControl_Writer::Transfer () is called multiple times in order to export a list of shapes to a common STEP file, the performance might be bad because the third parameter "compgraph" of the Transfer function is true by default. It means after every translation of a shape the graph is rebuilt.
Hi all, I'am a beginner, please help me.. my objectif is to import a .igs file and triangulate it, so i try to use three functions: 1- ImportIges(string filename); 2- FacesFromCompounds (const TopoDS_Shape &Shape, std::vector &topoFaceVector); 3- Triangulation_Occ();// in the function,i do three for
Read/Write DXF and SAT files ... As an old Cas.Cade customer my code use objects like : // specific SAT //#include //#include // specific DXF //#include //#include //#include Where have gone these objects in 3.0 ???
