Not able to use this utility locally in VSCode ?

Question

Not able to use this utility locally in VSCode ?

onkarp12 opened this issue 8 months ago · 12 comments

I want to test this utility and if possible, want to do some changes which are relevant for me. When I try all the mentioned steps and then tried running the utility it fails with error. The error dump is large and does not give any idea what went wrong. I am new to web development, so I followed the mentioned steps from readme file and only did one extra step of installing open cascade js explicitely.
"npm install opencascade.js@beta".

My node installed version is 20. Can you please guide on how to resolve the issue ?

Hi @onkarp12,

could you please also share the following information:

opencascade.js version number installed
changes made to the source code (if any)
command you tried to execute via the terminal

That will help me to remote debug your problem. Thanks!

BR, Georg

Answer 2 · 2024-04-23T10:31:44.000Z

Hello Georg, I have followed only steps mentioned in the readme file for developers.

Clone the Git repository:

git clone https://github.com/ghackenberg/opencascade-tools.git
Install development and production dependencies:

cd opencascade-tools && npm install
Afterwards you can use the following scripts:

🖥️ Scripts
Remove JavaScript binaries and TypeScript type definitions from previous builds:

cd opencascade-tools && npm run clean
Compile TypeScript sources to JavaScript binaries and TypeScript type definitions:

cd opencascade-tools && npm run build
Install your version of opencascade-tools into local NPM registry:

cd opencascade-tools && npm run deploy-local

As I mentioned earlier I was expecting all dependencies will get installed with this command "cd opencascade-tools && npm install" but somehow it is not the case for me. I did only one extra step of installing opencascade.js. Tried both commands.
"npm install opencascade.js@beta".
npm install opencascade.js@2.0.0-beta.b5ff984

When I tried to run locally from command prompt then it is not working and throwing dump.

Thanks,
Onkar

PS :
I am looking to read Attributes from STEP file( Dimensions, Color). Wanted to check the output with below code. Without my changes only I got problems, so I am not able to test the changes further.
reader.SetColorMode(true);
reader.SetGDTMode(true);
reader.SetLayerMode(true);
reader.SetMatMode(true);
reader.SetSHUOMode(true);

Answer 3 · 2024-04-23T11:04:22.000Z

Thank you for the details! I have one more question:

Are you getting the error when executing npm install opencascade.js@...?
Or are you getting the error when executing opencascade-tools ...?

Answer 4 · 2024-04-23T11:06:51.000Z

Getting the error when executing command like this from command line "C:\Users\OP>opencascade-tools --format gltf D:\warehouse-32.snapshot.1\Warehouse.step".

Answer 5 · 2024-04-23T11:11:54.000Z

Thanks! I think you are missing the --input flag. Could you please try the following command:

opencascade-tools --format gltf --input D:\warehouse-32.snapshot.1\Warehouse.step

You could also try the --help flag to print all the options that you can supply to the command:

opencascade-tools --help

Answer 6 · 2024-04-23T11:16:13.000Z

I just noticed that the documentation in the README file was not up-to-date. Fixed that!

Answer 7 · 2024-04-23T11:29:12.000Z

I am okay with this thread gets closed. Want to understand your thoughts if any. I want to display the PMI ( dimensions ) from STEP file to GLTF file.

I am able to successfully convert the STEP file to GLTF and used the same file for display purpose. But with code changes which I shared earlier; I am still getting same file. Is there anything I am missing?

Referred this link and tried changing the properties from code while reading STEP file.
https://dev.opencascade.org/doc/occt-7.6.0/overview/html/occt_user_guides__step.html#occt_step_7

 reader.SetColorMode(true);
reader.SetGDTMode(true);
reader.SetLayerMode(true);
reader.SetMatMode(true);
reader.SetSHUOMode(true);

======================================================

Answer 8 · 2024-04-23T16:41:44.000Z

I am not sure, what problem you are facing. Could you please explain again, what you are missing? Are you missing color information in the output for example?

I just tested the current version of the CLI on https://www.steptools.com/docs/stpfiles/ap214/as1-ac-214.stp. In the following, you see a screenshot of the original STEP file loaded with CAD Assistant. In the screenshot, you can see the assembly hierarchy stored inside the STEP file as well as the volumes and colors of the different parts.

The second screenshot below shows the GLTF model generated with the CLI. Again, the screenshot shows the generated assembly hierarchy as well as the part volumes and colors. Note that during conversion the coordinate system flips. Also the names of the assemblies change, because GLTF requires unique names of subassemblies.

Answer 9 · 2024-04-24T04:55:07.000Z

I am also using CAD Assistant to view the file. I have converted this particular file which has dimensions (PMIs) and converted the same to GLTF. I am not seeing the PMIs for GLTF format after using this utility.

Now after converting with utility.

Thanks,
Onkar

Answer 10 · 2024-04-24T18:31:16.000Z

Hi @onkarp12,

as far as I understand, the OpenCascade GLTF writer cannot (or does not) consider the PMI data. I assume that it only supports triangles and does not support "simple" line and path geometries, but not sure! Please read the following post from the OpenCascade forum to dive into the details:

https://dev.opencascade.org/content/xcaf-getting-gdt-visible-form

However, you can access the original PMI data using the OpenCascade API. The following post from the OpenCascade forum explains some details of using the OpenCascade API for PMI data extraction:

https://dev.opencascade.org/content/it-possible-create-pmi-gltf-files-and-make-it-visible

Maybe you can use a data format different from GLTF, which supports all, the assembly hierarchy, the part geometries, and the PMI data (not sure one exists!). Or you stick with GLTF for the assembly hierarchy and the part geometries, and use a different (maybe even custom) data format for the PMI data.

Answer 11 · 2024-04-29T17:42:06.000Z

Hi @onkarp12, did these links help you find a solution for your problem?

Answer 12 · 2024-04-30T08:55:43.000Z

Yes and NO. I have already gone through these links earlier before. I was looking for a sample code which will help me to guide through the process of reading PMI and a way to display in GLTF\web format.
I am looking for the sample code which helps me give idea on how to achieve this. Nevertheless, thanks for these links. Hope I will get some way to do this.

Hello Georg, I have followed only steps mentioned in the readme file for developers.

cd opencascade-tools && npm run deploy-local

Thanks, Onkar
