It would be possibile to have metadata (GENERAL_PROPERTY) in X3D?

Could STP2X3D generate a separate file output with these information ?

here the file
http://davidemercanti.altervista.org/sources/1M001934.stp

When running the make command, I get the following error:

/home/ec2-user/environment/STP2X3D/STP2X3D/STEP_Reader.cpp: In member function ‘std::wstring STEP_Reader::GetName(const TDF_Label&) const’:

I have installed OCCT 7.4.0, and I am running cmake 3.18 on AWS Linux 2.

I compiled the latest STP2X3D (VS2022+OCC7.6), and tested the file "nist_ctc_01_asme1_ap242.stp". The html generated by the STP2X3D only displays the CAD model, and does not display the corresponding GD&T data. But the strange thing is, using the "STEP File Analyzer and Viewer" can display the correct GD&T information. The attached file is the file I teste.
nist_ctc_01_asme1_ap242.zip

How can I solve the problem? Thank you

Thanks for your work on this tool, generally I'm getting great results, but occasionally I'm having issues with rough geometry on the output, despite the file size being quite small (3MB)

Checking the NIST SFA gui - low medium high options correspond to --quality flag of 4, 7 & 9 vs. range 1 - 10 available in STP2X3D.cpp.

Can you please advise if it output precision is limited by this range (and could be modified), or if this is a limitation of OCCT?

NB: I haven't tried using STP2X3D (not permitted to install Cmake at work), so just using the NIST SFA gui.

Hello,

I have used this source code to convert STEP file to X3D. The output which I got from this code and the STEP analyzer looks different. Did I miss anything ?

My HTML file snapshot once I ran the code.

Can you please check and suggest me changes if anything ? Also for me the dimensions are extra Tesellated Shapes ( Edge with Blue color) whereas for NIST viewer it is expected and also able to read datum there.

Regards,
Onkar

I noticed that colors are handled differently by m_colorTool->GetInstanceColor compared to Quantity_ColorRGBA::ColorToHex which seems more correct to me (compared to the usual implementations)

Is it possible to use Quantity_ColorRGBA::ColorToHex intead of GetInstanceColor?

R G B as single are =>.0024 .1619 .0222 but this is not true when using ColorToHex that returns correctly 087029FF

I found a problem with the name of some instances
in this Step file : Example
the name of the nodes contains special characters "LIFT-O-MAT®_2389SO300N_1" .
This name seems to break the flow of writing in the string when you get to the transform section. The file remains incomplete.

In stp2x3d.cpp the following include file is mentioned
#include "GDT_Item.h"
also used in Step_Reader.cpp

where do I find this and related files?
Thanks

Static Link to https://www.x3dom.org/x3dom/release/x3dom.js is broken in generated HTML-file.
Better a new commandline parameter, perhaps one wants the script/css on a local place.

I'm getting the following error when using the make command:

I've installed OCCT 7.4.0 successfully, and my includes are located in the following directory:

/usr/local/include/opencascade

How can I point to the right directory for the header files? I am installing on Linux.

environment:

• cmake 3.26.0
• visual studio 2017

project create by cmake-gui

when I build the project,it was stopped by error LNK1104:can not open file stdc++fs.lib。
Is there anyone can help me?

Hi.
In this model
http://davidemercanti.altervista.org/sources/1M001934.stp

Why the shape 9211204001 was built with only one material?

I would have expected to find 2 shapes with 2 different colors coded with different IndexedFaceSet
something like this:

Is it possible to add a Ubuntu 20.04 LTS build to the releases? The reason I am asking is beacuse I am not able to do it myself, as I dont understand how OCCT works.

Hello everyone,
I'm trying to compile the project and I fixed all the errors except this one. Can someone please help me?

The ap242 STP format model, GDT does not display correctly.

The STP model download address for AP242.
