Is it possible for ifccityjson to be an exe file?

[Pdongjaelee]

I need to make ifc into cityjson.

https://github.com/IfcOpenBot/IfcOpenShell/commit/0d3c73de822d1b11ebc31e21d3b946e2df15d30b#commitcomment-139858841

Can I make it into an exe file like this?

[Moult]

IfcCityJson does the opposite, it takes CityJSON and converts it to IFC, not the other way around.

And yes, you can turn that into an exe using pyinstaller. This is currently a very low priority but PRs are appreciated :)

[Pdongjaelee]

Can I prune ifccityjson here?

[Moult]

I'm sorry, I don't understand your question?

[Pdongjaelee]

If you post PRs, won't ifcopenbot create an exe like in the link?

[Moult]

IfcOpenBot currently only builds the C++ core. It does not package anything else (e.g. pip builds, bbim builds). So no, it won't create an exe for you. You can either create it yourself using pyinstaller, or add a github workflow so that it can be automatically created for others.

In fact, I have inquired before. My goal is to only need to convert ifc to cityjson. However, out of the 5 files I tried, only 2 were successful. I used ifcconvert for that. I am worried because the 3 ifc files are not converted to cityjson with ifcconvert.

Is there a good way?

[Moult]

This has been answered many times before in multiple channels. Is there still something which is unclear?

Yes, it hasn't been resolved yet. If I give you the files, can you tell me a good way to do it?

[Moult]

It's not resolved because:

1. There is no general solution right now for a computed simplification of complex geometry.
2. There is no "just serialise it" option in the regular IfcConvert, which will probably not give you what you want anyway.
3. Anything more practical probably requires scripting effort on your end, we can't do it for you. If you'd like to help hire a developer or provide funding, perhaps we can help consult though.
4. There seems to be a constant confusion between Ifc -> City and City -> IFC, it's not clear exactly what you want or how you want the geometry to end up looking like.

1. There is no general solution right now for a computed simplification of complex geometry. -> So, ifc with complex geometry cannot be converted?

2. Anything more practical probably requires scripting effort on your end, we can't do it for you. If you'd like to help hire a developer or provide funding, perhaps we can help consult though. -> Could it be possible to solve this problem if you provide funds? I am desperate.

3. There seems to be a constant confusion between Ifc -> City and City -> IFC, it's not clear exactly what you want or how you want the geometry to end up looking like. -> Ifc -> cityjson -> citygml I want to go like this. Two of the five files were converted to final citygml using this method. The problem is that the remaining three files failed. Ifc -> cityjson This part failed.

[Moult]

1. It can be converted, but maybe not with a one-size-fits-all clever algorithm. Maybe a dumber algorithm, heuristics, or multiple options selected by the user based on the project.
2. We don't immediately have spare resources on our end, but if you have a developer who knows C++ and/or Python, they can help (either in writing the CityJSON serialisation, or doing the Pyinstaller side, etc). You'll also need to fund that developer's time.
3. You'll also need graphics to understand what is considered appropriate cityjson. For example, do you really want your cityjson to contain geometry of doorknobs?

-> Oh, so you’re saying that complex forms are not possible with ifcconvert 0.8.0, which I currently use? If I give you a file that needs to be converted, can you check if conversion is possible?

2. We don't immediately have spare resources on our end, but if you have a developer who knows C++ and/or Python, they can help (either in writing the CityJSON serialisation, or doing the Pyinstaller side, etc). You'll also need to fund that developer's time.

->Does this help refer to helping me write an exe or code that will successfully convert the files I have? If so, I am willing to pay the funds.

3. You'll also need graphics to understand what is considered appropriate cityjson. For example, do you really want your cityjson to contain geometry of doorknobs?

-> Are you referring to the graphics in the file that failed to be converted?
